Innovation Solution

A pod-holding device utilizing a motor-driven screw system for sealed closure and expulsion, featuring a top and bottom subunit configuration with motors for precise control, allowing for safe and efficient operation within compact spaces, suitable for both aluminum and paper pods, and facilitated by a firmware-controlled system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spring systems or hydraulic systems are used for closing the pod-holder, then the pod can be securely sealed, but the device becomes bulky and complex

Engineering Contradiction:
Improvepod sealing reliabilityVSAvoidclosure system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex spring systems or hydraulic systems with a simpler mechanical screw system. The screw mechanism, driven by a motor, provides reliable sealing through controlled mechanical advancement of the top shell onto the bottom shell, eliminating the need for springs or hydraulic components while maintaining sealing reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts the essential function of sealing from complex auxiliary systems (springs, hydraulics) and achieves it through a simplified motor-driven screw mechanism. This extraction of the core sealing function removes unnecessary complexity while preserving the reliability of pod closure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If the pod-holder is made compact to fit small spaces, then space constraints are satisfied, but maneuverability for cleaning and pod insertion becomes difficult

Engineering Contradiction:
Improvepod-holder volumeVSAvoiddrawer maneuverability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent employs a drawer-type pod-holder that can dynamically extend and retract. During normal operation, the drawer is retracted to maintain a compact profile. During cleaning or pod insertion, the drawer can be manually extended to provide full access and maneuverability. This dynamic configuration allows the system to adapt between compact storage and operational accessibility.

Inventive Principle:
Principle #15Dynamics

3Force

If external lever systems are used for heater operation, then mechanical advantage is achieved, but parts project from the machine profile creating safety hazards

Engineering Contradiction:
Improvemechanical advantageVSAvoidsafety hazards from protruding parts
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the lever mechanism from the external profile of the machine and integrates it internally. The motor-driven screw system provides the necessary mechanical advantage for closing the pod-holder without requiring external levers to project from the machine body, thereby eliminating the safety hazard of protruding parts.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The screw mechanism and motor are nested within the compact pod-holder assembly, with all components contained within the machine profile. This nested configuration provides the required mechanical advantage while maintaining a smooth, protrusion-free external surface for safety.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Productivity

If sliding expulsion mechanism is used, then aluminum pods are easily expelled, but paper pods remain attached to the support shells

Engineering Contradiction:
Improvepod expulsion speedVSAvoidcompatibility with different pod types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The expulsion mechanism is segmented into multiple functional zones: a scraping zone with textured surfaces or brushes to dislodge paper pods, a lifting zone to elevate the pod, and an expulsion zone. This segmentation allows the system to handle both aluminum and paper pods effectively by providing different mechanical actions at different stages of the expulsion process.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention relates to a pod-holding device (100) for a beverage dispensing machine. The pod-holding device comprises a first (7) and a second (1 1 ) extraction subunit, the first extraction subunit (7) sealingly closing against the second subunit (1 1 ) so as to form, when closed, an extraction chamber for the pod, and, when open, allow insertion of the pod between the two subunits (7, 1 1 ).
