Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex connection system is used between wiper arm and blade adapters, then connection stability is improved, but assembly and disassembly become difficult requiring tools and significant user effort
Solution Approach 1:
The connection system is divided into separate positive locking elements on the wiper arm adapter and corresponding locking recesses on the blade adapter. These segmented components work together to provide both stable connection and easy operation through simple axial movement without requiring complex mechanisms or tools.
2Ease of operation
If a simple connection system is used between adapters, then assembly and disassembly become easy, but connection stability and force transmission are reduced
Solution Approach 1:
The connection system incorporates dynamic positive locking elements that can be easily deflected during assembly to engage with the locking recesses, providing simple operation. Once engaged, these elements maintain stable connection and force transmission through their rigid locked position, achieving both ease of operation and connection reliability.
3Strength
If positive locking elements are not accessible from outside, then structural integrity is maintained, but manual deflection and operation become impossible
Solution Approach 1:
The actuating elements are nested within the adapter body structure, allowing users to access and operate them from the outside. This nested design enables manual deflection of the positive locking elements while maintaining the overall structural integrity of the adapter, as the actuating elements are integrated into the existing structure rather than requiring external modifications.
