Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If battery modules are arranged compactly in the battery pack, then space utilization rate improves and overall safety and stability improve, but disassembly efficiency deteriorates and manual labor requirements increase
Solution Approach 1:
The disassembly device is segmented into multiple independent gripping mechanisms (first gripping device with hooks, second gripping device with locking elements, third gripping device with sucker) that can independently engage with different parts of the battery module. This segmentation allows the system to handle compactly arranged modules efficiently by applying localized gripping forces at multiple points simultaneously, resolving the contradiction between compact arrangement and disassembly efficiency
Solution Approach 2:
The gripping devices incorporate movable components including adjustable hook positions, transverse and longitudinal movable locking elements, and a suction cup system with adjustable positioning. These dynamic elements enable the device to adapt to different battery module configurations and extract modules from compact arrangements without requiring excessive manual intervention, thereby maintaining high space utilization while improving disassembly efficiency
2Device complexity
If conventional disassembling equipment with fixed structure is used, then device complexity is reduced, but adaptability to battery modules with different shapes and sizes deteriorates
Solution Approach 1:
The disassembly device integrates three different gripping mechanisms (hooks for protruding structures, locking elements for cylindrical grooves, and sucker for flat surfaces) into a single system. Each mechanism can be selectively activated depending on the battery module type, enabling one device to handle multiple module shapes and sizes. This multi-functionality approach maintains reasonable device complexity while achieving broad adaptability across different battery module configurations
Solution Approach 2:
The locking elements are designed to move both transversely and longitudinally along the connecting rack, allowing dynamic adjustment of their positioning and engagement depth. This dynamic capability enables the same device structure to adapt to battery modules of different dimensions and geometries without requiring multiple specialized devices, thus maintaining structural simplicity while achieving versatility
3Device complexity
If manual operation is used for disassembly, then device complexity is reduced, but labor requirements increase and automation level deteriorates
Solution Approach 1:
The disassembly device is designed to automatically identify and engage with the battery module features (hooks engage with protruding structures, locking elements insert into cylindrical grooves, sucker adheres to flat surfaces) without requiring manual positioning or intervention. The gripping mechanisms self-adjust and self-engage based on the module's geometry, enabling automated operation while keeping the device structure relatively simple and avoiding the need for complex sensors or control systems
