Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a complex gear system is used to reduce rotating power, then the user force requirement is reduced, but the device complexity and space occupation increase
Solution Approach 1:
The operation part is divided into a first operation part and a second operation part, each with its own housing and elastic member. This segmentation allows the system to store and release elastic energy in stages, reducing the peak force required by the user while avoiding the need for complex multi-stage gear systems.
Solution Approach 2:
The elastic members are pre-compressed during the operation cycle, storing energy before it is needed. The first elastic member is compressed as the first operation part rotates, and the second elastic member is compressed as the second operation part rotates, preparing energy for the lifting phase without requiring additional force from the user during the critical lifting moment.
2Power
If multiple gears are used to transfer torque, then the torque transfer is facilitated, but the device complexity increases
Solution Approach 1:
The patent extracts the torque multiplication function from the traditional gear system and replaces it with elastic energy storage and release mechanisms. The elastic members take out the function of torque amplification that would otherwise require multiple gears, simplifying the overall structure while maintaining effective torque transfer.
Solution Approach 2:
The system uses dynamic elastic deformation to achieve torque multiplication rather than static gear ratios. The elastic members dynamically compress and expand during the operation cycle, providing variable torque multiplication that adapts to the lifting requirements without requiring multiple fixed gear stages.
3Device complexity
If a simple structure is used, then the device complexity is reduced, but the torque transfer capability is insufficient
Solution Approach 1:
The second operation part is disposed inwardly of the first operation part, with the second housing containing the second elastic member inside the space occupied by the first operation part. This nested arrangement maximizes the use of available space, allowing the system to incorporate multiple energy storage elements without increasing the overall footprint, thereby maintaining simple structure while enhancing torque transfer capability.
