Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a power source with large capacity is used to achieve high torque and high speed, then the required work is satisfied, but the size, weight, and costs of the system increase
Solution Approach 1:
The patent divides a single large-capacity power source into multiple smaller power sources (first and second input units). Each power source operates independently but contributes to the total output through the gear unit, achieving the required power without the weight penalty of a single large motor.
Solution Approach 2:
The patent combines the outputs of multiple power sources through a gear unit that synthesizes their rotational forces. The gear unit merges the torque and speed from different input units to produce a combined output that satisfies high torque and high speed requirements.
2Power
If a gear transmission system is used to achieve both high-torque and high-speed output, then the required performance is obtained, but the mechanical configuration becomes complex and weight increases
Solution Approach 1:
The gear unit serves multiple functions simultaneously: it acts as a speed synthesizer, torque synthesizer, and differential mechanism. This multi-functionality eliminates the need for separate transmission stages, reducing overall system complexity while achieving both high-torque and high-speed outputs.
Solution Approach 2:
The system dynamically switches between different operational modes (speed synthesis, torque synthesis, differential operation) based on the rotation directions and speeds of the input units. This dynamic adaptability allows a single gear unit to replace multiple fixed-ratio transmission systems.
3Speed
If a planetary gear system is used for synthesizing input speeds, then speed synthesis is achieved, but the ability to synthesize torque and create various output properties is limited
Solution Approach 1:
The system dynamically switches between different operational modes (speed synthesis, torque synthesis, differential operation) based on the rotation directions and speeds of the input units. This dynamic adaptability allows a single gear unit to replace multiple fixed-ratio transmission systems.
Solution Approach 2:
The gear unit serves multiple functions simultaneously: it acts as a speed synthesizer, torque synthesizer, and differential mechanism. This multi-functionality eliminates the need for separate transmission stages, reducing overall system complexity while achieving both high-torque and high-speed outputs.

Implementation Method 2
A gear, which is formed with one of the first one-way bearing and the second one-way bearing which is different in power transmission blocking direction from the third one-way bearing, may be engaged with a planetary gear unit or a differential gear unit of the gear unit
Implementation Method 3
