Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a strengthening structure is provided inside the blade during assembly, then the structural integrity is improved, but the positioning accuracy deteriorates due to difficulty in ensuring correct positioning
Solution Approach 1:
The reinforcement parts are designed to be displaceable relative to each other during assembly, allowing dynamic adjustment to compensate for positioning inaccuracies. The adjusting means enable the reinforcement parts to move and self-align, transforming a static rigid structure into a dynamic adaptable one that can accommodate manufacturing tolerances while maintaining structural integrity.
Solution Approach 2:
The adjusting means change the positional parameters of the reinforcement parts during assembly, allowing them to shift from initial imprecise positions to correct final positions. This parameter adjustment capability enables the strengthening structure to achieve both high positioning accuracy and structural integrity by adapting to actual assembly conditions.
2Productivity
If force means are provided to force reinforcement parts apart during assembly, then the assembly efficiency is improved, but the device complexity increases
Solution Approach 1:
The force means are designed to automatically generate the necessary separating force during assembly without requiring external intervention. The reinforcement parts themselves, through their displaceable design and adjusting means, provide the force needed for their own positioning and alignment, eliminating the need for complex external forcing mechanisms and simplifying the overall assembly device.
Solution Approach 2:
The adjusting means act as an intermediary between the reinforcement parts and the assembly process, mediating the interaction by providing both the displacement capability and the force generation. This intermediary mechanism simplifies the assembly process by consolidating multiple functions (positioning, alignment, and forcing) into a single integrated component rather than requiring separate complex systems.
