Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a power source with large capacity is used to operate a robot or mechanical system with large torque at high speed, then the torque and speed performance is improved, but the size, weight, and cost of the system increase
Solution Approach 1:
The patent divides the single large-capacity power source into multiple smaller power sources (first, second, and third power sources). Each power source has smaller individual capacity, but their combined output through the gear system achieves the required torque and speed performance, thereby reducing overall system size and weight while maintaining performance requirements.
Solution Approach 2:
The patent combines the outputs of multiple smaller power sources through a gear unit to achieve the cumulative torque and speed of a single large power source. The gear unit integrates rotational forces from multiple inputs to produce a resultant output that meets the performance requirements of large torque at high speed without requiring a single large-capacity power source.
2Adaptability or versatility
If a gear shift system is used to achieve both high-torque output for smooth driving on a slope and high-speed output for high-speed driving, then the torque and speed versatility is improved, but the device complexity increases
Solution Approach 1:
The gear unit is designed to perform multiple functions simultaneously - it can combine torque from multiple power sources, adjust speed ratios, and provide various output characteristics (high torque or high speed) based on the operational requirements. This multi-functional design eliminates the need for separate gear shift mechanisms while achieving both high-torque and high-speed capabilities.
Solution Approach 2:
The system dynamically adjusts output characteristics by varying the contribution of each power source and the reduction ratios through the gear unit. The gear system can adaptively change between torque-combining mode and speed-combining mode, providing dynamic versatility without requiring complex mechanical gear shifting mechanisms.
3Speed
If a planetary gear system combining input speeds is used, then the speed combination capability is improved, but the inability to combine torque limits the output characteristics variety
Solution Approach 1:
The gear unit is segmented into multiple functional paths that can independently combine torque and speed. The system can selectively engage different power sources and combine their torque outputs separately from speed combinations, allowing for greater variety in output characteristics by independently controlling torque and speed combination pathways.
Solution Approach 2:
The patent merges both torque combination and speed combination capabilities into a single integrated gear unit. Unlike previous systems that only combined speeds, this gear unit simultaneously provides torque combination functionality, enabling the system to achieve a wider variety of output characteristics by combining both torque and speed from multiple power sources.
4Adaptability or versatility
If a complex mechanical system such as a gear shift system is used to achieve various output characteristics, then the output versatility is improved, but the cost and weight increase
Solution Approach 1:
The gear unit is designed as a universal mechanism that can provide multiple output characteristics (high torque, high speed, various speed-torque combinations) through a single integrated structure. This eliminates the need for separate gear shift systems, thereby reducing system weight and cost while maintaining output versatility.
Solution Approach 2:
The patent combines the functions of multiple power sources and the gear shift system into a single integrated gear unit that achieves various output characteristics. By merging torque combination, speed combination, and gear ratio adjustment into one unit, the system reduces overall complexity, weight, and cost while maintaining the ability to provide diverse output characteristics.
