Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lifting plate is used to place the battery during compression and penetration tests, then both tests can be conducted, but the lifting plate shakes under external force making it difficult to achieve accurate test results
Solution Approach 1:
The device separates the lifting function from the testing function by introducing a dedicated lifting device with lifting blocks, while the base block with guide bars provides stable support for compression and penetration tests. This segmentation allows each component to perform its specific function without interfering with the other.
Solution Approach 2:
The lifting blocks act as intermediaries between the lifting device and the battery, providing stable support during lifting operations. The guide bars serve as intermediaries to guide the movement of pressure blocks, ensuring accurate positioning during compression tests.
2Stability of the object's composition
If four guide bars are installed to guide pressure blocks, then the direction of transfer is guided, but the total size of the device increases and stability is reduced due to high center of gravity
Solution Approach 1:
The invention extracts the guiding function from multiple guide bars and concentrates it into a single guide bar structure. This guide bar is positioned to extend in the longitudinal direction and guide the pressure blocks effectively, reducing the overall device size and lowering the center of gravity while maintaining directional guidance capability.
3Ease of operation
If the battery is placed on the lifting plate during tests, then the battery can be positioned for testing, but fire heat can directly transmit to pressure cylinders causing device damage
Solution Approach 1:
The fireproof chamber acts as an intermediary barrier between the battery and the pressure cylinders. It allows the battery to be positioned for testing while preventing fire heat from directly transmitting to the pressure cylinders, thus protecting the device from fire damage.
Solution Approach 2:
The fireproof chamber creates a protected environment that isolates the pressure cylinders from the harmful effects of fire, allowing testing to proceed while maintaining device safety.
