Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If holding means are used to position the coupling rod relative to wiper bearings, then manufacturing precision and ease of assembly are improved, but device complexity increases
Solution Approach 1:
The holding means are pre-integrated into the wiper bearing structure, establishing predetermined positioning relationships between the coupling rod and wiper bearings before assembly. This preliminary configuration ensures precise alignment during installation without requiring complex external positioning mechanisms.
Solution Approach 2:
The holding means are merged with the wiper bearing structure, combining the functions of bearing support and positioning into a single integrated component. This reduces the number of separate parts and simplifies the overall device structure while maintaining precise alignment capabilities.
2Stability of the object's composition
If traditional consoles are used to connect wiper bearings, then structural stability is improved, but weight and manufacturing cost increase
Solution Approach 1:
The holding means are integrated directly into the wiper bearing structure, eliminating the need for separate console components. This merging of functions reduces the overall weight of the wiper system while maintaining structural stability through the unified design.
Solution Approach 2:
The traditional heavy console structure is extracted and replaced with simplified holding means that are directly formed as part of the wiper bearing. This extraction removes unnecessary weight while preserving the essential structural support and positioning functions.
3Stability of the object's composition
If traditional consoles are used to connect wiper bearings, then structural stability is improved, but manufacturing cost and space requirements increase
Solution Approach 1:
The holding means are combined with the wiper bearing structure, reducing the total number of parts that need to be manufactured and assembled. This integration simplifies the manufacturing process and reduces costs while maintaining structural stability through the unified design.
Solution Approach 2:
The wiper bearing structure is segmented to include integrated holding means, allowing for modular manufacturing and assembly. This segmentation enables cost-effective production while ensuring stable structural configuration.
