Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If free drop test from certain height is used, then test simplicity is maintained, but test representativeness deteriorates due to inability to simulate actual road conditions
Solution Approach 1:
The patent applies dynamics by making the dropping platform adjustable in both angle and height. The platform can be tilted to various angles (0-90 degrees) and positioned at different heights, allowing the battery case to be dropped under diverse simulated road conditions rather than a fixed vertical drop, thereby improving test representativeness while maintaining operational simplicity through mechanical adjustability.
Solution Approach 2:
The patent changes key parameters of the dropping system - specifically the dropping angle and height - to simulate different road conditions. By allowing continuous adjustment of these parameters, the test device can replicate various real-world scenarios (different road slopes, impact heights) without complicating the basic drop test mechanism, thus resolving the contradiction between simplicity and representativeness.
2Ease of operation
If fixed angle and height drop test is used, then test operation is simple, but adaptability to different road conditions deteriorates
Solution Approach 1:
The dropping platform is designed with dynamic adjustability, allowing it to be tilted to different angles and positioned at various heights. This dynamic capability enables the same simple drop test mechanism to adapt to multiple road conditions without requiring complex test procedures, maintaining operational simplicity while enhancing versatility.
Solution Approach 2:
The patent creates a universal test platform that can perform multiple functions by adjusting its configuration. The same platform structure serves different purposes by changing its angle and height settings, allowing a single device to simulate various road conditions rather than requiring separate test setups for each scenario.
