Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two staggered elastic members are used to increase elasticity, then the elastic performance is improved, but the fixing arm of one elastic member blocks the connecting arm of the other elastic member during welding, resulting in poor welding quality
Solution Approach 1:
The elastic member is divided into distinct functional segments: a fixing arm for attachment to the base, elastic arms for providing elastic force, and connecting arms for attachment to the vibrating unit. This segmentation allows each part to perform its specific function without interfering with the welding process of other parts, as the fixing arm and connecting arm are spatially separated.
Solution Approach 2:
The elastic member utilizes three-dimensional spatial arrangement to resolve the blocking issue. The fixing arm and connecting arm are positioned at different locations and orientations in space, allowing the welding process to access the connecting arm without being blocked by the fixing arm. The staggered arrangement in multiple dimensions enables both elastic members to be welded simultaneously or sequentially without interference.
2Strength
If two elastic members are oppositely arranged to clamp the vibrating unit, then the elastic performance is enhanced, but the assembly process becomes complex and welding is difficult due to mutual blocking
Solution Approach 1:
The elastic member is designed as a segmented structure with distinct fixing arm, elastic arm, and connecting arm portions. This segmentation simplifies the assembly process by allowing each component to be independently positioned and welded, reducing the complexity associated with assembling oppositely arranged elastic members.
Solution Approach 2:
The fixing arm is designed to be welded to the base first, establishing a stable foundation before the connecting arm is welded to the vibrating unit. This preliminary action sequence simplifies the overall assembly process by pre-positioning the elastic member on the base, making subsequent assembly steps more straightforward despite the oppositely arranged configuration.
