Accessibility-focused rotary storage system

Abstract

The invention enables containers (6) to remain horizontally aligned on linear and curved paths through passive balancing and sequential guiding without the use of sensors or actuators. In the closed-loop configuration, pin (6.3) engages with the guide channel (4.7) via the entry mouth (4.7a); in multi-path transitions, pins (6.3, 6.3a) engage with the curved (4.8) and linear (4.9) channels. During normal operation, transport is contactless, while in oscillation scenarios, brief and controlled interaction occurs. The 45° corner chamfer (6.2) prevents edge snagging; symmetrical arrangement and compact turning radii provide collision-free high-volume efficiency. The system is modular and operates via manual indexing or optional motorized drive. Alignment marks on the static structure and the defined tolerance / measurement regime ensure repeatable precision positioning of the containers (6) and guides.

Description

[0001] DESCRIPTION ACCESSIBILITY-FOCUSED ROTARY STORAGE SYSTEM

[0002] Technical Field

[0003] The invention relates to a rotary storage system that is distinct in purpose and functionality, developed for enabling quick and user-interaction-friendly access to items located especially in upper shelves or rear sections that are difficult to reach, found in logistics and industrial storage / access applications as well as in household cabinets, drawers, and similar storage areas.

[0004] Prior Art

[0005] Previously, several types of shelving systems such as back-to-back shelving systems, dynamic shelving systems, cantilever shelving systems, and mezzanine shelving systems have been available and in use, each with its own disadvantages. These systems can briefly be described as follows:

[0006] Back-to-Back Shelving System: Commonly used for storing pallets or metal containers. It offers maximum storage space and the possibility to store multiple pallets side-by-side. Perforations at different intervals in the upright profiles provide flexibility in shelf height. It can operate with manual or automated stacking machines and enables storage of different products through special accessories.

[0007] Dynamic Shelving Systems: Generally operate based on gravity principles and are particularly designed in accordance with the FIFO (First In First Out) principle. The sliding speed of pallets in these systems can be controlled with brake mechanisms, and maintenance costs are generally low.

[0008] Cantilever Shelving System: An ideal system for long, irregularly shaped, and mixed loads. It can be used outdoors or indoors. Heavy-duty cantilever racks are offered in single- or double-sided models, and require special calculations to ensure resistance to weather conditions in outdoor use. It is very suitable for storing wooden bundles, metal profiles, and other long and heavy loads.

[0009] Mezzanine Shelving System: A shelving system in which a platform system is created using shelf uprights. It provides additional usable space by combining the maximum height of warehouses with a platform. The number of levels in the system determines the warehouse volume, thereby optimizing vertical use. These systems, which allow manual loading, offer advantages for placing and accessing products at desired locations. Manual pallet trucks can be used on walking platforms, and the entire system can be disassembled and moved when necessary.

[0010] These shelving systems are primarily designed for palletized / heavy-load logistics purposes; their intended use and scale differ from the individual access-oriented arrangements described in this application. Such systems are generally used in industrial environments.

[0011] Traditional cabinets have a shelf configuration with doors; deep compartments and upper / lower positions may create specific accessibility limitations. The solution addressed in this application explains a different use scenario by approaching the problem through positioning containers at the point of access.

[0028] Closest Prior Art - Problem / Solution Bridge

[0029] The closest prior art comprises rotary storage / conveyor-based solutions, which do not holistically resolve the issue of maintaining the horizontal position of the container during transfer without active components and increasing the volumetric capacity by reducing pitch. This application addresses the problem through:

[0030] (i) sensorless maintenance of horizontal orientation via dual pin-sequential channel architecture,

[0031] (ii) interference-free transition and pitch reduction through chamfers,

[0032] (iii) a pin-channel interface designed to ensure a limited contact area with edgecatching and wedge-locking prevention geometry and surface quality. In normal operating regimes, the interface remains contactless; during oscillation damping phases, short and controlled interactions occur. Objectives of the Invention

[0033] To establish an integrated layout of the pin-channel kinematics (6.3, 6.3a 4.7b / 4.8a / 4.9a) that ensures contactless and interference-free transport of containers (6) during rotation and sensorless continuity of horizontal positioning.

[0034] To ensure collision-free flow and safe transition during approach-separation phases by eliminating edge capture / wedge effect through 45° corner chamfering (6.2).

[0035] To implement a geometry based on symmetrical layout that provides superior volumetric efficiency at the storage radius; the geometric / mathematical framework and validation methods are disclosed in the specification as exemplary and non-limiting.

[0036] Another objective of the invention is to define modular geometric options (e.g., 4.7b channel width, 4.7a entry angle, container types) for rapid adaptation across scenario selection — configuration — operational scheme phases (parameter names are for illustration, not limitation).

[0037] Summary of the Invention

[0038] The invention is a passive-balanced and drive-independent storage / transport system based on the interaction between the container (6), balance pins (6.3, 6.3a), channels (4.7b, 4.8a, 4.9a), concentric motion elements (4.4, 6.1 ), central rotary mechanism (4), and static assembly (B). The container (6) is suspended from the concentric motion elements (4.4) via a suspension element (6.1 ); the dual balance pins (6.3, 6.3a) engage in sequential and region-selective contact with different segments of a single guide path, i.e. , the circular track channel (4.7b), curved channel (4.8a), and linear channel (4.9a).

[0039] In the normal operating regime, load is borne solely by the suspension elements (4.4, 6.1 ); the pin-channel interface is contactless. During oscillation phases, only one balance pin becomes active in the relevant region: in closed loop segments and curved transitions, pin (6.3) engages with guides (4.7, 4.8); in linear transitions, pin (6.3a) engages with linear guide (4.9). Thus, on a hybrid path composed of linear and curved segments, only the relevant pin-channel pair is active in each region; the other pin remains passive, minimizing jamming and wedge-locking risk. The corner chamfer (6.2) and surface quality form the geometry that limits edge capture in the pin-channel interface; the clearance A = w_k - d_p and minimum approach distance 5_min, selected in conjunction with the tribological condition tan [3 > p+, enable interference-free high-density operation and oscillation damping under passive balance, even in compact turning radii. The system is configured to operate independently of drive mechanisms through manual indexing; optional motor / actuator modules following the same kinematics are merely illustrative and do not limit the scope of the claims.

[0040] Fields of Application

[0041] This system is suitable for modular storage / distribution in residential, office, commercial, and industrial environments. Thanks to passive balancing and sequential guidance, containers (6) remain horizontal throughout the cycle without sensors or actuators. Indexed presentation windows that can be positioned at user-accessible heights reduce bending / reaching distances and enable rapid sequential access. Compact turning radii and modular container interchangeability allow quick adaptation to different scenarios.

[0042] Corner chamfering (6.2) and the pin-channel interaction (6.3, 6.3a 4.7b / 4.8a / 4.9a) ensure interference-free transitions and flow continuity within the container-channel- neighboring container envelope; as turning radii decrease, usable volume increases proportionally.

[0043] This architecture provides repeatable, reliable, and scalable usage across a wide range of domains such as logistics lines, pharmaceutical distribution units, component management, and in-home modular storage. Variants deviating from this architecture require closed cams, sensor-actuator ecosystems, or tightly toleranced machining to achieve equivalent non-contact stability-factors that elevate production and maintenance costs.

[0044] Key Benefits of the Solution

[0045] Sensorless Horizontal Stability Containers (6) are concentrically suspended via the container suspension element

[0046] (6.1 ) on the concentric motion element (4.4); passive balance and sequential guidance maintain horizontal alignment throughout the cycle without active sensors or actuators; presentation repeatability is high.

[0047] Modular Architecture and Ergonomics: A standardized suspension interface, interchangeable container types, and configurable access openings (front / rear / top) enable management of differently sized / shaped items within the same system. Indexed presentation windows reduce bending / reaching distances and support rapid sequential access.

[0048] Cleaning and Servicing: The removable container structure enables users to accelerate cleaning and maintenance tasks.

[0049] Storage Density and Flow Continuity: With 45° profile-matched corner chamfering

[0050] (6.2) and symmetrical placement, interference-free transfer is achieved at compact turning radii; usable volume is increased.

[0051] Jamming-Free Flow and Anti-Wedge Behavior: The pin-channel interface (6.3, 6.3a <- 4.7b / 4.8a / 4.9a) ensures contactless operation in normal regimes through edge-capture-preventing geometry and surface quality; during oscillations, brief and controlled engagement occurs.

[0052] Drive-Independent Operation: Regardless of defined geometric and parametric conditions (tan [3 > p+, A = w_k - d_p > A_min, b_min > x), the system is configured for full functionality under manual indexing based solely on passive balance kinematics provided by concentric motion elements (4.4, 6.1 ), balance pins (6.3, 6.3a), and guide channels (4.7b, 4.8a, 4.9a).

[0053] Definitions

[0054] Direction and Coordinate Definitions: The terms “right / left / front / rear / top / bottom” and “inner / outer” used in this specification are based on a dedicated Cartesian coordinate system (X, Y, Z) defined specifically for this document and established in Figure 1 . The coordinate system is fixed to the system body (A).

[0055] • X-axis: The device’s horizontal front-rear direction (+X: front).

[0056] • Y-axis: Vertical direction (+Y: upward). • Z-axis: The rotation axis passing through the center of the rotary assembly. Positive rotation direction for Z follows the right-hand rule.

[0057] “Normal operating position” refers to the device’s mounting and operational orientation; all other figures use the same directional reference. “Inner” and “outer” are defined relative to the volume of the system body (A). (See Figure 1 -2 for general view; Figures 12-15 for arm / container positions and reference markings.)

[0076] - Tribology: p+measured by linear reciprocal tribometer; sampling > 100 Hz; steadyphase average > 10 cycles.

[0078] Note: This section does not limit the scope of the claims; it serves only to standardize instruction and validation.

[0079] 2.6 Precision Alignment and Repeatable Positioning (Non-Limiting)

[0080] The static assembly (B) includes alignment marks indicating the installation positions of the containers (6) and the guides (4.7, 4.8, 4.9); these marks are placed based on the reference angles and orientations shown in Figures 1-2 and the corresponding detail drawings. During assembly, the container (6), suspension element (6.1 ), and pins (6.3, 6.3a) are connected to the concentric motion elements (4.4) based on these markings. Values of w_k, d_p, A, and b_min are measured using a CMM / contactless probe and evaluated considering tolerance stack-ups and alignment deviations; configurations satisfying the acceptance criteria A > A_min and b_min > x are preferred for oscillation damping and interference-free transition. This alignment and validation regime does not limit the scope of the claims; it supports the skilled person in configuring the system with repeatable precision and in accordance with the passive balance principle.

[0081] 3. Oscillation Kinematics and Contact Regime

[0082] While the container (6) is carried by the concentric motion elements (4.4, 6.1 ), it also undergoes oscillation during the cycle. Under normal operation, the pin-channel interface is contactless; during oscillation damping phases, short and controlled contact occurs. A static jamming regime is not anticipated.

[0083] Active Pin-Channel Matching

[0084] While passive-balanced transport is maintained throughout the cycle, only one balance pin (6.3 or 6.3a) actively engages with the corresponding guide segment in each path regime. In the closed-loop segment and curved transitions, pin (6.3) engages sequentially with the guide channel (4.7b) and curved channel (4.8a); during the linear transition, pin (6.3a) engages with the linear channel (4.9a). The other pin remains in a passive state within geometric bounds for that region. This segment-selective engagement reduces jamming risk along the single-path hybrid route and limits pinchannel contact to oscillation damping moments.

[0085] The mechanism supports the following path regimes:

[0086] (i) Circular track: Pin (6.3) engages with channel (4.7b) through entry mouth (4.7a).

[0087] (ii) Transition tracks: (a1 ) 6.3 4.8a in the open-ended curved section,

[0088] (a2) 6.3a 4.9a in the channel with curved ends and a straight body; transition between (a1 ) and (a2) is possible.

[0089] The geometry and surface quality of the pin-channel interface are dimensioned to prevent edge capture and wedge-locking; thus, oscillation effects are dampened and cycle stability is maintained. 4. Operational Threshold - Wedge-Locking Prevention

[0090] Acceptance Criterion (Design Guide): tan p > p+

[0091] Definition and Validation: Valid for values of p and p+. Determined in accordance with the measurement methods defined in Sections 2.1-2.3. Validation is performed based on the measurement procedures and tolerance budget (emax) described in Section 2. The methods and parameters used are explicitly stated in the report.

[0092] Note (illustrative, non-claim): Does not limit the scope of the claims.

[0093] 5. Placement Trigonometry and Collision Avoidance

[0094] 5.1 Geometric Framework

[0095] • Symmetrical Arrangement: Container centers are arranged at equal angular intervals around the rotation axis.

[0096] • Angular Step: 0 = 3607n

[0097] • Placement Radius: r = D / { 2 [ 1 + (1 / sin(1807n)) ] }

[0098] • Definitions: n = number of concentric containers; D = outer circle diameter.

[0099] • Objective: To define the geometric basis for a non-overlapping and balanced arrangement that maximizes volumetric efficiency.

[0100] 5.2 Validation (Example / Preferred Configuration; Non-Limiting)

[0101] • Measurements (in assembled state): w_k = shortest distance [mm] between opposing lateral faces of the channel (4.7b) d_p = diameter [mm] of the largest inscribed circle within the cross-sectional silhouette of balance pin (6.3)

[0102] A = w_k - d_p (clearance) bmin= Euclidean distance [mm] between the container (6) and the hannel / neighboring elements

[0103] • Acceptance Criteria: A > A min and b min > x Method: Measurements taken via CMM / contactless probe; evaluation includes worstcase tolerance stack-up and measurement uncertainty budget emax.

[0104] Note (Section 5.2 is illustrative, non-claim): This section serves instructional / validation purposes and does not limit the scope of the claims.

[0183] Primary Configuration The invention comprises a combination of container (6), balance pins (6.3, 6.3a), and channels (4.7b, 4.8a, 4.9a), including:

[0184] (i) In the 360° continuous rotation segment:

[0185] Pin 6.3 —> (insertion into channel) 4.7a — 4.7b; and

[0186] (ii) In multi-path routing regimes:

[0187] . (a1) 6.3 - 4 ,8a - involves curved guide (4.8), which includes curved channel (4.8a) designed as a circular arc segment. The central angle <p of this curved channel corresponds to the designated curvature in the design. (Examples: <p = 180° — semi-circle; <p = 90° — quarter-circle. These examples are illustrative and non-claim.)

[0188] During the movement of the rotary mechanism (C), the curved channel (4.8a) inside the continuously orbiting curved guide (4.8) and the container (6) with its curved-path balance pin (6.3) track along a congruent curved trajectory. This pairing follows bidirectional matching.

[0189] • (a2) The linear-path balance pin (6.3a) on the container (6) enables transition between segments via the linear channel (4.9a), which features curved ends and an open structure. During multi-path regimes, when the curved-path balance pin (6.3) exits the curve, the linear-path balance pin (6.3a) begins entering the linear channel (4.9a). The reverse occurs at the other end of the same curved path.

[0190] This configuration preserves the balance regime and maintains sensorless horizontal alignment of the containers. (See Figure 24)

[0191] Chamfers (6.2) have been applied to the containers (6), forming an integrated combination that increases usable volume by allowing motion without collision or contact between containers and the assembly. These elements collectively constitute the core technical features of the invention. The type of drive used is not limiting.

[0192] The invention is an accessibility-focused rotary storage system in which all mechanical parts operate in harmony, with appropriate structural strength and in accordance with mechanical engineering principles. It includes load-bearing supports (1 ) that ensure the positioning, stability, and balance of the rotary mechanism (C) housed within, and that carry the load of the entire system (A). Each of the load-bearing supports (1 ) includes shaft concentric motion elements (2) rigidly mounted in a concentric configuration to the concentric motion element mounting area (1.1 ), bearing the full load of the rotary mechanism (C) (Figure 6).

[0193] The system incorporates various concentric rotation elements (1.1 - 2 - 4.4 - 6.1 ), designed for rotary storage solutions in residential and living spaces. These elements may include bearings, belt and shaft systems, gear mechanisms, free-hanging components, and ball bearings, each associated with a rotational function wherever referenced.

[0194] The rotary mechanism (C) comprises at least one central rotation mechanism (4) and at least one shaft (3). To maintain the general balance of rotating components within the system (A), the rotary mechanism (C) is equipped with at least three item containers (6). In this storage system, which typically includes two central rotation mechanisms (4), the shaft (3) is affixed at both ends to the central rotation mechanisms (4).

[0195] In the central rotation mechanism (4), concentric motion element mounting areas (4.2) are designed concentrically around the shaft seating socket (4.1 ) at a predefined radial distance. In a storage system (A) with five item containers (6), the angular position of each concentric motion element mounting area (4.2) equals 36075, or more generally, 360° divided by the number of item containers (6) (Figure 7).

[0196] Accordingly, the concentric motion element mounting areas (4.2) are spaced at angular intervals of 72°, each at an equal predefined radial distance. The concentric motion elements (4.4) may be designed as an integrated part of the central rotation mechanism (4) or as areas into which motion elements (4.4) are later inserted.

[0197] The item containers (6) are the fundamental components forming the storage space in the accessibility-focused storage system (A). The containers (6) are mechanically coupled to the motion elements (4.4) in the central rotation mechanism (4) by means of container suspension elements (6.1 ), allowing them to remain freely suspended.

[0198] The accessibility-focused storage system (A) features two different rotation tracks. The first track involves the transfer of containers (6) along a 360° rotation of the rotary mechanism (C). This track is designed for disassembly and relocation between environments, allowing adaptation to different locations such as kitchens, pantries, garages, and workshops.

[0199] The second rotation track is intended to utilize the space occupied by the system (A) in a linear form, particularly to optimize the depth usage of a confined residential space. This structure redirects the system’s occupied volume in different directions-e.g., using the vertical axis by mounting the storage system (A) to the floor or wall, utilizing vertical height instead of floor depth. Thus, both storage capacity is maximized and floor area usage is optimized.

[0200] To enhance system functionality, at least one pair of drive shafts and concentric motion elements (4.4) are incorporated in a belt-driven, flexible central rotation mechanism (4). Due to its modular design, this structure is not limited in track length and provides an effective and organized storage solution across width and depth constraints-between a kitchen and a basement pantry, above a kitchen counter, or in narrow spaces such as small pantries, shoe stores, pharmacies, and medical supply depots. The rotary mechanism (C) enables quick access to stored products and, with its structure designed to elevate the volume envelope, maximizes spatial efficiency.

[0201] As the number of item containers (6) increases within the same volume, their height and depth are reduced in a non-proportional but trigonometric relationship. In wheelshaped rotary systems, container (6) angular intervals and maximum usable diameters are determined based on system capacity, with each calculated using 3607n. This formula ensures maximally sized balanced distribution of item containers (6):

[0202] • D: Diameter of the outer circle

[0203] • r: Radius of the inner circles

[0204] • 0: Central angle between the circles

[0205] • d: Straight-line distance between centers of circles

[0206] • n: Number of inner circles (containers)

[0207] 0 = 360° / n r = D / { 2 ■ [ 1 + (1 / sin(1807n)) ] }

[0208] Calculation Example (n = 5, D = 600 mm): e = 360° / 5 = 72° r = 600 / { 2 ■ [1 + (1 / sin(36°))] }

[0209] « 600 / { 2 ■ [1 + (1 / 0.587785)] }

[0210] « 600 / (2 ■ 2.701301 )

[0211] « 600 / 5.402602

[0212] « 111.06 mm

[0213] Note: All angles in this specification are expressed in degrees (°); trigonometric terms such as sin and cos are evaluated with degree arguments. Unless explicitly stated otherwise, all angles in this specification are in degrees (°).

[0214] In these equations, D refers to the diameter of the outer circle traced by the containers (6) in the X-Y plane (as defined in Figure 1 ); r is the radius of the inner circle traced by the container centers; 9 is the central angle between two adjacent container centers; d is the chord length between these centers. All directions and axes correspond to the X-Y-Z coordinate system defined in Figure 1 , and manufacturing tolerances are specified in the corresponding technical drawings.

[0215] To maximize the volumetric efficiency of system (A), all containers (6) used in the circular track are symmetrically arranged and designed in equal dimensions as rectangular prisms, other polyhedral forms, or cylindrical shapes.

[0216] Access to containers (6) may be provided from any direction except the bottom, depending on the type and structure. The side walls extending from the base edges of the containers (6) serve as load-bearing elements that enable the attachment of the containers (6) to the rotary mechanism (C). Each predefined inner circle, positioned within the inner boundary envelope of a reference circle defined by these trigonometric principles and considered tangent (without physical contact) to the inner boundary envelope of the main circle, defines the maximum projection of the container’s (6) bearing surface-regardless of container geometry. During assembly, 5_min > 0 is maintained.

[0217] The suspension elements (6.1 ) of the containers (6) are positioned directly above the center of the reference inner circle and at equal heights relative to each other. The inner boundary envelope of the reference circles is maintained, thereby lowering the center of mass of the container (6) towards the ground and supporting its tendency to remain parallel to the horizontal plane (Figure 6, Figure 8, Figure 9, Figure 13). Each container (6) is symmetrically arranged at equal angular intervals and distances around the central axis of the rotary mechanism (C) and shaft (3), and is positioned so as not to contact other containers (6). These containers (6), possessing a balance structure that ensures stability during rotation, are designed to remain suspended on the rotary mechanism (C) and maintain their position while moving up and down (Figures 10-12).

[0218] The height of the concentric motion element placement area (1.1 ) is designed such that when the container (6) reaches the lowest level, its bottom remains safely above the ground (Figures 1 , 2, 12, 20). This design enables efficient storage of items packaged in regular or standard shapes, such as cylindrical or polyhedral forms.

[0219] For storage of both rigid rolls like baking paper or aluminum foil and flexible items such as sponges or cloths, container height and depth dimensions have been increased to expand volume. To prevent contact between containers, the lateral comers are chamfered (6.2) in accordance with a 45° sectional profile.

[0220] The chamfering (6.2) operation provides containers (6) with significant usable volume. Although the chamfered corner regions result in a minor volume loss, this enhances the overall system efficiency by preventing contact during movement.

[0221] Each container (6) is designed to be removable from the rotary mechanism (C) for cleaning or other purposes. Additionally, optional removable inner containers (6.4) compatible with all container (6) sizes are available. These inner containers (6.4) are equipped with movable compartments, allowing the internal volume to be tailored to individual needs and container dimensions, thereby optimizing ergonomics and enabling more personalized organization of contents (Figure 21 ).

[0222] The system is structured such that during motion, neither the containers (6) nor their contents make contact with any other element, preventing locking of the rotary mechanism (C) (Figure 13).

[0223] Some items are not well-suited to closed environments. In such cases, structural flexibility is introduced to the containers (6) while ensuring maximum volume and seamless transport during operation. Different chamfer ratios are applied to the lower and upper portions of the container (6); however, these are proportionally defined to maintain the total geometric envelope of the lower and upper lateral corners. (Illustrative / non-claim: for explanation purposes: 30% / 70%; 35% / 65%) (Figure 15)

[0224] Such ratios may be required for delicate or bulky items. When all containers (6) in the system have chamfering (6.2) with different ratios between top and bottom sections, each ratio is individually calculated, and container placement on the rotation track is designed using trigonometric relationships to meet non-contact principles (Figure 14).

[0225] Due to the inward slope formed by the chamfer (6.2) at the bottom, no internal chamfers are formed on inclined interior surfaces for rigid items packed in polyhedral, cylindrical, or other regular geometries; the external lateral chamfer (6.2) is maintained according to the 45° sectional guideline.

[0226] For curved items, containers (6) are designed with integrated curved slots that conform to the contour of the items-such as plates in kitchen cabinets-to achieve the highest volumetric and numerical capacity. These containers (6) are designed to be placed as closely together as possible while ensuring that neither the containers nor their contents contact anything during motion or cause mechanical interruptions, thereby maximizing capacity.

[0227] In studies encompassing various scenarios, container (6) placement precision has been finely tuned using computer-aided design (CAD) software to maximize spatial efficiency and storage capacity.

[0228] During the design process, considerations include the maximum load capacity of the selected materials, the number of containers (6), environmental conditions, and atmospheric chemistry in coastal or marine regions. Accordingly, materials are selected for their corrosion and mechanical resistance, such as stainless steel, polymer composites, aluminum alloys (e.g., 6061 , 7050, 7075), or coatings designed for durability.

[0229] For lighter and more cost-effective implementations, engineering plastics and high- strength, low-cost materials may be utilized.

[0230] The rotation-based mechanical elements used in the storage system (A) are designed for mechanical resistance against humidity, iodine, and saline air. Elastomer-based friction components ensure smooth and quiet operation of moving parts. This configuration enables the system to function reliably even in domestic environments, requiring minimal maintenance and supporting user ergonomics, all while providing exceptionally quiet usage.

[0231] This invention evaluates the usable volume variation in containers (6) placed within the same boundary envelope under non-overlapping rotational conditions within the static structure (B), based on their cross-sections.

[0232] For a square envelope with side length s, if a cylinder with an equivalent diagonal diameter is used, the radius becomes: r = s / ^2, and the area ratio becomes:

[0233] 1.57

[0234] Assuming equal container depths, the volume ratio is also:

[0235] Hence, cylindrical container configurations can provide up to 57% higher total volume compared to non-chamfered (6.2) square containers.

[0236] This result assumes constant values for wall thickness (t), spacing between containers (g), and functional tolerance (5). (See Figures 22-24)

[0237] Inner container (6.4) contributes to the centering of the center of mass and spatial organization inside the main container in multiple configurations (see Figure 15, Figure 21 ).

[0238] In certain systems (A), multi-directional access is a design goal: containers (6) can be loaded from one direction and unloaded from another. These containers generally consist of a base and two supporting walls and are custom-designed for the specific application. For temporary fixation of inserted or removed items, such containers may also be equipped with removable inner containers (6.4).

[0239] Oscillation Restriction Mechanisms

[0240] A system-specific design includes an oscillation-preventing mechanism for singleshaft carousel architectures. The mechanism is implemented in two structural variants for the storage system (A), and all mechanical parts of these structures and their related connections are manufactured from high-strength materials such as steel.

[0241] Variants:

[0242] • First variant: For systems with rotating storage around a single-shaft (3) axis and at least three containers (6).

[0243] • Second variant: For systems incorporating at least one drive shaft (3) and flexible drive elements such as gears or pulleys driving a centrally rotating mechanism (4) via belts or chains.

[0244] This second variant features curved and linear segments in its storage trajectory. (See Figures 22, 23, 24)

[0245] Definitions:

[0246] Suspension Elements:

[0247] • Concentric motion element (4.4): The anchoring point located on the rotary mechanism (C) for attaching radial structures, carried within the centrally rotating mechanism (4).

[0248] • Container suspension element (6.1): Located on container (6) and aligned concentrically with the concentric motion element (4.4), enabling the container to be suspended and coupled to the rotating mechanism (4) through radial suspension structure (6.1 ).

[0249] • Relation (6.1) «-> (4.4): Element (6.1 ) is matched to (4.4), maintaining the concentricity condition. (See Figures 5, 6, 8)

[0250] In single-shaft systems, the container (6) is suspended via the container suspension element (6.1 ), which is concentrically mounted to the concentric motion element (4.4) located at the end of the arm (4f) that is part of the centrally rotating mechanism (4) connected to the rotary mechanism (C). To support user access ergonomics, depending on the architectural preferences of system (A), an example configuration positions the container at ±2-3° angular tolerance (illustrative only; not part of claims).

[0251] In X-direction (as defined in the coordinate system), access to the container is provided at either -36° (54°) or +36° (124°) from the 90° vertical, and the angular positions can be arranged based on the reference position of the first slot.

[0252] In this configuration, the entry mouth (4.7a) of the curved guide (4.7) opens in the X- direction, within the Y-axis direction from outer to inner frame, and approximately at the angle at which the rotary mechanism (C) presents the container (6) for access (illustrative and non-binding).

[0253] The center of the curved guide (4.7) is exactly concentric with the center of the concentric motion element (4.4).

[0254] The radius of the curved channel (4.7b), opened at the midpoint thickness of curved guide (4.7), is equal to the distance between the radial center of the container suspension element (6.1) and the radial center of the curved balance pin (6.3). The pins (6.3) extend outward from the outer wall of the load-bearing container (6) and are directed into the curved channel (4.7b).

[0255] Each container (6) has at least one curved guide (4.7) containing one curved channel (4.7b) and one pin (6.3). (See Figure 22)

[0256] During assembly, as the container (6) is mounted onto the concentric motion element (4.4) via its container suspension element (6.1), the pin (6.3) simultaneously enters the curved channel (4.7b) through the entry mouth (4.7a). The entry mouth (4.7a) can be configured to open and close using various techniques depending on application and preference.

[0257] The distance between the container suspension element (6.1 ) and the pin (6.3) may be critical depending on the application; the radius of the channel (4.7b) matches this (6.1 )-(6.3) spacing. Increasing this distance reduces the instantaneous mechanical stress experienced during oscillation. In 360° storage systems (A), each container (6) is associated with at least one channel (4.7b) and entry mouth (4.7a) located on a circular guide ring (4.7). This stabilization system is mounted on one or more carrier walls of the container (6) (e.g., on both structural sides).

[0258] The curved-path pin (6.3) is centrally aligned in the channel (4.7b). The pin’s length is determined such that it does not contact the bottom of the channel. The width of the channel (4.7b) is designed to minimize the gap between the inner channel walls and the cylindrical surface of the pin (6.3). This minimal clearance is defined per design dimensions, load capacity, and the type of content being carried.

[0259] At least one of the shaft-like connectors (e.g., drive shaft) located at the center of the curved path is motor-driven.

[0260] In this configuration, the flexible belt-pulley or chain-gear driven central rotary mechanism (4) serves as the actuated component. The length of this rotary mechanism (4) and the spacing of concentric motion elements (4.4) are designed to match the non-contact spacing required between containers (6). (See Figures 16- 18)

[0261] Example of Unbounded Multi-Channel Regime: In systems with both linear and curved paths, each shaft (3) connects to a shaft slider (4d), which contains arms (4f).

[0262] Each arm (4f) terminates in a curved channel (4.8a) that is open at the mouth. The location of each guide (4.8) is concentric with the concentric motion element (4.4) and the container suspension element (6.1 ). The radius of the channel (4.8a) equals the distance between the centers of elements (4.4 and 6.1 ) and the center of the pin (6.3).

[0263] When the path of the curved channel (4.8a) matches the orbital trajectory of the curved-path pin (6.3) located on the container (6), and an oscillation event occurs, the pin (6.3) makes contact with at least one inner wall of the channel (4.8a), thereby restricting the oscillation angle. This prevents the containers (6) from tipping or colliding with other content in the system (A). In Multi-Arm Systems with Linear Paths: Each shaft slider (4d) typically holds four arms (4f), with each arm terminating in a curved guide (4.8), which is designed as a circular arc segment.

[0264] The central angle <p of each arc corresponds to the segment design. Examples (non-limiting):

[0265] • <p = 180° semicircle

[0266] • <p = 90° — quarter circle

[0267] The pin (6.3) and the curved channel (4.8a) follow synchronized curved trajectories.

[0268] In systems with multiple shafts (3), the entry ends of the curved channels (4.8a) connected to opposing shafts are arranged in opposite directions to ensure synchronized tracking along the same path.

[0269] Shaft Count and Design Guide: Due to structural requirements, the number of arms (4f) connected to the shaft slider (4d) may vary in multi-shaft or pulley-chain gear systems.

[0270] Design Guide (non-binding example):

[0271] For multi-shaft variants, a rule of thumb:

[0272] <p_max » 2-(360° / k) (where k is the number of arms)

[0273] This eases entry-exit path continuity. The value of cp can be adjusted according to application needs.

[0274] In systems with small, closely spaced containers (6), if the transfer path (arc) does not exceed the maximum radial angle of the curved channel (4.8a), it can be optimized to accelerate the transfer of containers (6).

[0275] Design and Placement of Linear Guides (4.9):

[0276] Linear channels (4.9a) form the outbound and return paths. The center-to-center distance between these linear guides (4.9) matches the nominal diameter of the corresponding rotation path.

[0277] Their design accommodates tolerance stacking and assembly deviations.

[0278] In vertically oriented systems, the guide (4.9) is positioned such that, when the arm (4f) is in a horizontal state, the channel (4.9a) is aligned vertically on the carrier wall of the suspended container (6) and is fixed to the static structure (B). (Refer to Figures 23 and 24)

[0279] The constraining gap (A) at the pin-channel interface is defined as: A = wk- dp, where contact with the inner channel walls within this A range terminates free swinging kinematically. Material type, stiffness, and the maximum error budget (emax) are selected to prevent elastic or permanent damage.

[0280] The ends of the channels (4.9a) extend along the initial portion of the arc followed passively by the pin (6.3a) during entry and exit from the curved track. The curvature radius of this extension matches the radial distance between the pin (6.3a) and the shaft (3) centers.

[0281] This ensures that when the curved-track pin (6.3) enters or exits channel (4.8a), the linear pin (6.3a) remains properly seated within the linear channel (4.9a), allowing for uninterrupted anti-sway function during transitions.

[0282] Principle of Operation - Anti-Sway System

[0283] Containers (6) are carried in a freely suspended configuration, designed so that their center of gravity remains downward toward the ground. The container bases remain approximately parallel to the ground plane.

[0284] The suspension point (container suspension element 6.1 ) and the linear pin 6.3a are aligned along a common horizontal line, while the suspension point 6.1 and the curved- track pin 6.3 are aligned along a common vertical line.

[0285] When sway dynamics occur, the container (6) begins to swing about the suspension axis (6.1 ), and the pins (6.3, 6.3a) move along the same circular path. If any external disturbance or operational dynamics induce swinging, the pins (6.3, 6.3a) make instantaneous contact with the inner surfaces of the channels (4.7b, 4.8a, 4.9a), thereby terminating the swing kinematically.

[0286] Operational Sequence and Transitions

[0287] On the opposite side of the transfer path, transitions occur in reverse. Once pins (6.3, 6.3a) leave channels (4.8a, 4.9a), they remain passive until they reenter their designated guides.

[0288] During normal operation, load-bearing is handled by the suspension elements (6.1) and concentric motion components (4.4).

[0289] In the event of momentary sway along the linear path, the limited interaction between pin (6.3a) and channel (4.9a) helps dissipate energy, reduce oscillation amplitude, and shorten transient response time.

[0290] Friction remains low and does not negatively impact the drive system.

[0291] The guide geometries (4.8, 4.9) and dimensions can be adapted per application; however, the core function of the balancing pins (6.3, 6.3a) remains unchanged.

[0292] Bevel Angle and Friction

[0293] The bevel angle p, defined along the bisector of the corner chamfer, is selected to satisfy: tan p > p+, where p+is the kinetic coefficient of friction. This prevents wedge-locking at the interface.

[0294] (Design guideline; non-limiting example)

[0295] Example:

[0296] In corner regions, a reference circle (R_ref) can be defined using trigonometric analysis. The bevel geometry is selected to leave at least (100 - x)% of this circle’s diameter within the clearance envelope. This example is illustrative and does not limit the scope of the claims.

[0297] “Zero to Zero + x” Clearance Strategy

[0298] The clearance (5min) from the nearest point to a neighboring component (e.g., guide, cabinet, or adjacent element) is chosen following a “zero to zero plus x” strategy. Here, x represents the safety margin required to accommodate total tolerance stacking and dynamic deviation.

[0299] (Acceptance criterion; non-limiting example)

[0300] Pin Surface Quality

[0301] The balancing pin (6.3) must meet surface roughness and tip radius standards. This ensures proper edge behavior and prevents wedge effects.

[0302] In fully manual designs, the system (A) is tailored to its structural configuration and load capacity.

[0303] This variant allows the user to manually rotate the rotary mechanism (C) by turning the knob (4.5) located on it.

[0304] Such a system (A) is ergonomically designed to be accessible for all healthy users without requiring exertion.

[0305] In certain high-load applications, the shaft (3) is manufactured from high-strength alloys and designed to withstand the forces generated during motion.

[0306] Its connection to the concentric motion elements (2) is supported by structural arrangements that ensure uniform distribution of the torque applied at the shaft ends (3.3).

[0307] To prevent damage to the shaft (3) under overload conditions, the system may incorporate kinematic constraint mechanisms-such as belts connected to pulleys placed at strategic points on the rotary mechanism (C)-that absorb excess rotational motion within elasticity tolerances.

[0308] Damping wheels may also be employed to ensure a safe system configuration. As shown in Figures 6, 8, and 10, the shaft ends (3.3) are either driven into or suspended from the shaft concentric motion elements (2) housed within the carrier supports (1). These supports are rigidly secured in an upright position, and the entire system is designed so that no component of the carrier support (1) comes into contact with the rotary mechanism (C).

[0309] This enables the rotary mechanism (C) to rotate freely in compliance with mechanical principles.

[0310] The rotary storage system (A) is designed with structural flexibility to accommodate various user-specific needs through different configurations. (Figures 1 , 2, 6, 16, 18, and 20)

[0311] As seen in (Figures 7, 10, 13, and 15), when maximizing spatial efficiency-especial ly in situations where utilizing vertical height is preferred over horizontal depth-the rotary mechanism (C) may be driven by one or more shafts or chain sprockets using central rotary mechanisms (4) such as belts or chains to optimize vertical space utilization.

[0312] Manual Drive Variants

[0313] In manually actuated systems with multiple shafts, rotation is achieved by applying hand force to knobs (4.5) that are coaxially integrated with at least one pulley. One shaft may include a telescopic knob lever (4.5) mounted concentrically to the shaft seat (4.1).

[0314] This configuration can include a ratchet mechanism, which enables smooth movement of the rotary mechanism (C) even when transporting containers (6) with heavy loads to the access point.

[0315] Disclaimer

[0316] Motor-driven implementations are non-limiting examples; all values are approximate and subject to manufacturing tolerances.

[0317] The methodology is not limited by this example; only the claims define the scope of protection.

[0318] Optional Drive / Electronic Control (Non-claimed Feature) The system is inherently configured for manual operation, regardless of the geometric or parametric requirements.

[0319] To replicate the same kinematics, an optional motor / actuator and electronic driver may be added.

[0320] This optional module is not part of the claims and does not affect the scope of protection.

[0321] It also does not alter the core container-pin-channel interaction, and the design criteria tan p > p+, A = wk- dp> Amin, and 6minstill apply.

[0322] The following passage is an example application and not within the claimed scope:

[0323] Motor-Driven Applications

[0324] In motorized versions, at least one electric motor is included.

[0325] Preferably, this motor is a servo step motor compliant with NEMA standards, integrated with a custom-programmed closed-loop electronic control kit. These motors are compact yet capable of producing high torque in the range of 8- 20 N-m, making them suitable for space-constrained designs with user-centric layouts.

[0326] A controller board integrated into the motor module continuously monitors torque and position, enabling real-time compensation for weight imbalance, thus promoting smooth and vibration-free operation.

[0327] Because of their low-voltage operation, these systems offer a safe user experience. The rotation angle of the motor's drive shaft is constantly monitored via closed-loop control, and instantaneous torque adjustments are made when imbalances are detected.

[0328] The system’s acceleration, travel, deceleration, and stopping phases are finely tuned to be extremely gradual and stable, virtually eliminating sway or vibration. This enhances mechanical stability and allows for fewer components, contributing to simplified design and cost efficiency.

[0329] The central rotary mechanism (4) can interface with a variety of drive belts or chains compatible with the concentric motion elements (4.4). In typical household use, the system is activated a few times per day for item retrieval or storage. Each operation moves the drive components over a distance of less than 80-100 cm, minimizing mechanical wear and allowing for extended maintenance intervals.

[0330] Material Considerations and Use Cases

[0331] Multi-shaft, accessibility-focused storage systems can be fabricated using various material classes, chosen for durability and wear resistance to ensure long service life.

[0332] This approach maintains belt / chain flexibility and ensures consistent performance. All metallic components are treated with anti -corrosive coatings.

[0333] Container (6) Adaptability

[0334] The dimensions and construction of containers (6) are adaptable to the system’s circular motion.

[0335] These variations accommodate a broad range of item types and sizes and enable flexible height configurations.

[0336] Designed to be compatible with standard kitchen cabinets and other furniture modules, the containers easily accommodate dinner plates, jars, and liquid cartons.

[0337] In environments where aesthetic integration is secondary-such as pantries, garages, or workshops-the containers and system structures are designed with greater dimensional flexibility to fit items of diverse size, weight, and type.

[0338] For managing heavy items manually, the system can incorporate telescopic arms (4f) and mechanical jacks.

[0339] When combined with dual-shaft (3) configurations, this mechanism facilitates lower- effort handling of heavy containers (6) mounted on the rotary mechanism (C) and ensures a safe, user-friendly experience.

[0340] The concentric motion elements (4.4) are robustly integrated into the belt, chain, or similar transmission structures that form the transport line of the rotary mechanism (C), ensuring mechanical integrity. This type of accessibility-focused storage system is, by design, not limited in height or track length; for example, it can span across two rooms-from a kitchen on the main floor down to a basement pantry.

[0341] In over-counter storage system (A) applications, the access opening of the containers (6) is oriented horizontally from the front for direct reachability. In undercounter or similar installations, the access opening is positioned on the upper side of the containers (6), operating within a predefined vertical range aligned with ergonomic reach zones (See Figures 16 and 18).

[0342] Electrically Assisted Variants - User-Centric Interface Design

[0343] In some electrically powered and panel-controlled rotary storage systems (A), each container (6) may be assigned a dedicated command button.

[0344] Pressing this button moves the corresponding container (6) to the access position. All buttons are marked with tactile symbols, color codes, and numerals.

[0345] • Tactile markings assist visually impaired users in identifying the correct button by touch.

[0346] • Color and number coding serve as guides for users with memory impairment or color blindness.

[0347] Universal Design Architecture

[0348] The invention provides a system architecture that is adaptable to residential, commercial, and industrial environments, as envisioned during the design phase.

[0349] The objective is to establish a general -purpose storage and transport solution that:

[0350] • maintains the physical balance of containers (6) during movement and at rest,

[0351] • supports sequential organization and access to personal items,

[0352] • and enhances user interaction and autonomy. Cost-Effective Manufacturing Considerations

[0353] To ensure cost-effective production, high-strength but cost-efficient materials are employed for structures that support the free rotation of the rotary mechanism (C). This enables slow yet stable movement, allowing the system to remain entirely manually operated, thus eliminating costly fine manufacturing processes.

[0354] In such manual designs:

[0355] • The outer rim of the rotary mechanism (C) features tactile and colored markings.

[0356] • When these markings align with corresponding indicators on the static structure (B), the containers (6) are correctly positioned.

[0357] • Visually impaired users can identify the correct position by touch, and acoustic signals can notify users when the container (6) has arrived at the access point.

[0358] • The acoustic feedback can be activated or deactivated based on user preference.

[0359] Safety and Interaction
