Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliances face issues with sluggish container movement, especially when fully loaded, and complex inner container designs that result in stability problems and inefficient use of space.
Innovation Solution
A household refrigeration appliance featuring a carrier carriage with rollers for smooth movement guidance, a mobile tray design that absorbs weight forces evenly, and a plate-shaped supporting part with a frame for enhanced stability and versatility, allowing for variable container positioning without lateral space constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage devices are integrated into the inner container to guide container movement, then movement guidance is provided, but the inner container becomes complex in shape and production complexity increases
Solution Approach 1:
The guide device is extracted from the inner container structure and implemented as a separate, independent component. The guide device includes guide channels formed on the floor of the inner container, while the carrier carriage has corresponding guide elements that engage with these channels. This separation allows the inner container to maintain a simple, depression-free structure while the guide device provides the necessary movement guidance functionality.
2Stability of the object's composition
If storage devices are integrated into the inner container to provide stability, then stability is improved, but lateral space is consumed and interior volume is reduced
Solution Approach 1:
The stability-providing guide functionality is extracted from the side wall structure and implemented on the floor of the inner container through guide channels. The carrier carriage moves along these floor-based guide channels, providing stability and guidance without requiring lateral protrusions or depressions in the side walls, thus maximizing the usable interior volume.
3Reliability
If linear guides are used to guide carrier carriage movement, then movement guidance is provided, but the guides can be overloaded when extensively loaded and lateral space is required
Solution Approach 1:
The guide device transitions from traditional lateral linear guides to a floor-based guide channel system. The guide channels are formed on the floor surface and extend in the depth direction, allowing the carrier carriage to move along a predetermined path without requiring lateral clearance. This dimensional repositioning of the guide structure eliminates lateral space requirements and distributes loads along the floor structure rather than concentrating them in lateral guide rails.
