Solution Overview

Problem

Existing containers are inflexible, leading to inefficient use of storage space and potential mixing of media due to rigid tank arrangements, difficulty in accessing small volumes, and unsuitability for applications with hygiene requirements.

Innovation Solution

A container design with at least one flexible device within a receiving space, allowing variable volume distribution and separate access to media through multiple openings, with devices that can be detachably connected to prevent mixing and ensure hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate containers are used to store different media, then media mixing is prevented, but handling complexity and storage space utilization increase

Engineering Contradiction:
Improvemedia separationVSAvoidhandling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate containers into a single container system with internal partitioning. Multiple receiving spaces are created within one container structure, allowing different media to be stored separately while enabling unified handling and transport of the entire system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container is segmented into multiple receiving spaces using partition walls. Each receiving space can be independently filled with different media, maintaining media separation while being part of a single container unit that simplifies handling.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If rigid tank arrangements are used, then structural stability is maintained, but storage space utilization decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage space utilization
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The partition walls are designed to be movable rather than fixed, allowing the receiving spaces to dynamically adjust their volumes. This enables optimal space utilization as media is added or removed, while the overall container structure remains stable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The volume parameters of the receiving spaces can change as partition walls move. This allows the system to adapt the storage volume of each receiving space based on the actual quantity of media present, maximizing storage efficiency.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If flexible separating layers are used to create variable volumes, then storage flexibility increases, but access to small volumes becomes difficult

Engineering Contradiction:
Improvestorage flexibilityVSAvoidmedia access
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Gutter channels are introduced as intermediary structures that run along the container walls, providing dedicated pathways for media supply and removal. These channels ensure that even small volumes in corner areas remain accessible by guiding media flow away from difficult-to-reach regions.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If separate containers are used for media supply and collection, then media mixing is prevented, but storage space efficiency decreases

Engineering Contradiction:
Improvemedia separationVSAvoidstorage space efficiency
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent merges the functions of separate supply and collection containers into a single integrated container system. Multiple receiving spaces within one container allow simultaneous storage of different media (e.g., fresh water and gray water) without mixing, while utilizing the total container volume efficiently.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention relates to a container (1) for receiving at least one medium, preferably a fluid. To this end, the container (1) has a container wall (2), which defines a first receiving space with a first receiving volume (3), and a first device (10), which is arranged within the first receiving space and defines a second receiving volume (11). In order to provide a container (1) having separate receiving volumes, in which, for example, if a device is damaged, not all the receiving volumes are directly connected together and in which the total volume of the container is used optimally, the container (1) has at least one second device (20), wherein the second device (20) is arranged within the first receiving space and defines a third receiving volume (21). In addition, the first device (10) and/or the second device (20) are configured to be variable such that the second receiving volume (11) and/or the third receiving volume (21) are variable with respect to the first receiving volume (3). Furthermore, the container (1) has at least two openings (4, 12), which are designed to feed a medium to the first receiving volume (3) and/or to the second receiving volume (11) and/or to the at least one third receiving volume (21) and/or to discharge it therefrom.
