Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional torque conversion mechanisms are used, then torque output can be increased, but the complexity of the device increases and efficiency is insufficient
Solution Approach 1:
The device is divided into two independent rotors (first rotor and second rotor) that can rotate independently, connected by simple link portions. This segmentation allows each rotor to function independently while maintaining a relatively simple overall structure, avoiding the need for complex multi-stage transmission mechanisms.
Solution Approach 2:
The patent introduces a vertical dimension by positioning the rotating shafts of the first and second rotors at different heights (first shaft at higher position, second shaft at lower position). This spatial arrangement in three dimensions allows for torque multiplication without requiring complex horizontal gear trains or multi-stage mechanisms.
2Device complexity
If simple mechanisms are used for torque conversion, then device complexity is reduced, but output torque cannot exceed input torque
Solution Approach 1:
The link portions are designed to be movable rather than fixed, allowing dynamic adjustment of the mechanical connection between rotors. The link portions can rotate and change orientation as the rotors turn, enabling the system to exploit centrifugal forces and dynamic momentum to achieve torque multiplication beyond what static mechanisms can provide.
Solution Approach 2:
The patent changes the physical parameters of the system by introducing weights attached to the rotors and utilizing the centrifugal force generated by rotating masses. By adjusting parameters such as rotor mass distribution, rotational speed, and link geometry, the system achieves torque multiplication without complex mechanical advantage structures.
3Force
If weights are attached to link portions for centrifugal force generation, then torque output increases, but the device complexity increases
Solution Approach 1:
The weights are merged with the rotors themselves rather than being separate components. The first and second rotors incorporate the weighting masses as integral parts, eliminating the need for separate weight attachment mechanisms and reducing overall structural complexity while still generating the necessary centrifugal forces for torque multiplication.
