Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional torque transmission systems are used, then torque can be transmitted, but the transmission is not strong and smooth enough
Solution Approach 1:
The patent employs circular elements (first and second partial circular elements) connected by a linear web element to form a curved geometric structure. This circular configuration enables smooth torque transmission through distributed stress paths, eliminating the jerky transmission characteristic of straight-line mechanisms and providing continuous harmonic motion.
Solution Approach 2:
The patent transforms the rigid straight-line connection into a flexible curved configuration by changing the geometric parameters of the transmission path. The linear web element connects the circular elements at specific angles, creating a mechanism that converts rotational motion into harmonic oscillation, thereby changing the transmission characteristics from direct to smoothed torque delivery.
2Strength
If a simple transmission mechanism is used, then device complexity is low, but torque transmission strength and smoothness are insufficient
Solution Approach 1:
The spring element is divided into distinct functional segments: the linear web element providing structural connectivity, and the first and second partial circular elements providing rotational compliance. This segmentation allows each component to be optimized for its specific function while working together to achieve strong and smooth torque transmission.
Solution Approach 2:
The spring element functions as a composite mechanical structure combining linear and circular geometric forms in a single integrated component. This composite geometry enables the element to simultaneously provide structural strength through the linear web and torque-smoothing compliance through the circular elements, achieving enhanced performance without requiring multiple separate components.
