Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If electrical equipment is mounted to an inside or outside of the battery pack using existing methods, then the battery pack can include necessary electrical components, but the structure becomes complicated and the volume increases
Solution Approach 1:
The patent combines multiple electrical equipment components (BMS, current sensor, relay, fuse) onto a single plate-shaped electrical equipment plate. This merging approach consolidates what would otherwise be separate mounting requirements into one integrated structure, reducing overall complexity while maintaining all necessary electrical functions.
Solution Approach 2:
The electrical equipment plate serves multiple functions simultaneously: it acts as a mounting substrate for various electrical components, provides structural support, and facilitates organized electrical connections. This multi-functionality eliminates the need for separate mounting structures for each component.
2Quantity of substance
If electrical equipment is mounted using existing methods, then the battery pack can be assembled, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
Multiple electrical components are pre-mounted onto the electrical equipment plate before the plate is installed into the battery pack. This preliminary assembly reduces the number of separate installation steps required during final assembly, significantly improving productivity and reducing assembly time.
Solution Approach 2:
By combining multiple electrical components onto a single plate, the patent reduces the number of separate assembly operations needed. Instead of installing each component individually into the battery pack, the entire assembly is installed as one unit, streamlining the manufacturing process.
3Quantity of substance
If electrical equipment is installed with a complicated structure, then the battery pack can include necessary components, but the exchange and maintenance become difficult
Solution Approach 1:
The patent segments the electrical equipment into a modular plate assembly that can be easily removed and replaced as a single unit. This segmentation allows maintenance personnel to quickly exchange the entire electrical equipment plate without having to work with individual components, significantly improving ease of repair.
Solution Approach 2:
The electrical equipment plate is designed as a extractable module that can be easily removed from the battery pack. This extraction capability allows for quick replacement of electrical equipment during maintenance or upgrades without requiring complex disassembly procedures.
