Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual folding of legs and guides is used, then device complexity is reduced, but time to enter side storage space is extended
Solution Approach 1:
The docking assembly is pre-configured with docking units positioned on both sides of the battery case. Before the battery needs to be accessed, the docking assembly can be quickly deployed into the vehicle, with the docking units already in place to receive and support the battery case, eliminating the need for manual folding operations during the time-critical battery access phase.
Solution Approach 2:
The docking assembly incorporates rotatable docking units that can dynamically adjust their position and orientation. The ability to rotate and fold the docking units allows the structure to transition between different configurations quickly, reducing the time required to enter or exit the side storage space while maintaining structural integrity.
2Device complexity
If only one leg is disposed at a side portion of battery housing, then device complexity is reduced, but battery case stability deteriorates
Solution Approach 1:
The docking units are positioned asymmetrically on both sides of the battery case, with the first docking unit at one end and the second docking unit at the opposite end. This asymmetric distribution of support points creates a more stable configuration that prevents the battery case from moving or tipping during insertion and removal operations.
Solution Approach 2:
The support structure is segmented into multiple independent docking units rather than a single leg. Each docking unit can independently support the battery case, and the segmentation allows for better weight distribution and stability while maintaining relatively simple individual component designs.
3Ease of manufacture
If manual folding of legs is required, then ease of manufacture is improved, but ease of operation deteriorates
Solution Approach 1:
The docking assembly is designed to automatically perform the folding and deployment actions through its mechanical linkage system. When the vehicle moves or when the docking button is activated, the push block automatically pushes the docking units to rotate and fold, eliminating the need for manual intervention and making the system self-operating while maintaining manufacturing simplicity.
4Productivity
If automated docking assembly with rotatable units is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The docking assembly serves multiple functions: it supports the battery case during insertion, provides stability during operation, enables quick deployment, and allows for easy retrieval. By integrating these multiple functions into a single multi-functional docking structure with rotatable units, the system achieves high productivity without requiring separate mechanisms for each function, thereby limiting the increase in overall complexity.

AI summary
The vehicle battery attachment/detachment device includes a battery case that accommodates a battery therein and moves into a vehicle in a width direction of the vehicle, and a docking assembly that is rotatably coupled to the battery case and is folded to move into the vehicle together with the battery case or is unfolded to move the battery case to an outside of the vehicle.
