Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large quantity of components is used to implement folding and unfolding, then the foldable mechanism can achieve stable folding function, but the structure becomes complex and assembly precision deteriorates
Solution Approach 1:
The patent merges multiple separate components into integrally formed pressing plates and swing arms. The pressing plate integrates the pressing surface, support portion, and auxiliary portion into a single component, while the swing arm integrates the rotating portion and sliding portion. This merging reduces the total number of components, simplifies the structure, and improves assembly precision while maintaining the stable folding function through the integrated design that preserves necessary mechanical relationships.
2Ease of manufacture
If multiple separate components are used for pressing plate and swing arm, then assembly flexibility is improved, but assembly precision deteriorates due to multiple connection interfaces
Solution Approach 1:
By integrating the pressing plate components (pressing surface, support portion, auxiliary portion) and swing arm components (rotating portion, sliding portion) into single unified components, the patent eliminates multiple connection interfaces between these parts. This reduces the cumulative error accumulation from multiple assemblies, thereby improving overall assembly precision while the integrated structure maintains manufacturing feasibility through modular integral forming processes.
3Adaptability or versatility
If a complex structure with many components is used, then functional requirements are met, but weight increases and lightweight design is hindered
Solution Approach 1:
The patent reduces the total number of components by merging separate pressing plate parts and swing arm parts into integrally formed structures. This reduction in component quantity directly decreases the overall weight of the foldable mechanism while the integrated design maintains all necessary functional requirements through preserved geometric relationships and mechanical properties within the unified components.
