Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-stage gears are used to transfer motion in the rotating mechanism, then the folding terminal product can achieve housing deformation and folding/unfolding functionality, but the synchronous movement performance of the two housings is degraded and the device complexity increases
Solution Approach 1:
The patent removes the complex multi-stage gear transmission mechanism from the rotating mechanism and replaces it with a direct connection structure. This extraction of the disturbing gear components eliminates the cumulative errors and synchronization issues while preserving the essential folding/unfolding functionality through the simplified arm-based mechanism.
Solution Approach 2:
The rotating mechanism is segmented into independent synchronous arms (first synchronous arm and second synchronous arm) that can rotate independently around separate shafts. Each arm is connected to its respective housing and can be individually controlled, allowing for precise synchronous movement without the need for complex gear interactions. This segmentation enables better control over the motion of each housing.
2Adaptability or versatility
If multi-stage gears are used in the rotating mechanism, then motion transfer is achieved, but the quantity of components increases and the cooperation relationship becomes complex
Solution Approach 1:
The patent extracts and removes the multi-stage gear components from the rotating mechanism, replacing them with a simplified direct-connection structure using synchronous arms and shafts. This reduction in component quantity simplifies the overall mechanism while maintaining the essential motion transfer capability needed for housing deformation.
Solution Approach 2:
The synchronous arms serve as intermediary elements that directly connect the shafts to the housings, eliminating the need for complex gear intermediaries. Each synchronous arm acts as a simple rotational link that transfers motion directly from its shaft to its connected housing, simplifying the cooperation relationship between components.
