Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional coaxial devices with multiple components (flexible part, external joint, pin, nut, inner joint, ring, ring nut, anti-friction bushing) are used to maintain coaxial rotation, then the coaxial alignment is achieved, but the device complexity increases and manufacturing difficulty increases
Solution Approach 1:
The patent combines multiple separate components (flexible part, joints, pins, nuts, rings, bushings) into a single integrated flexible damping device. The device features a unified structure with damping elements directly embedded in the flexible body, eliminating the need for separate fastening and alignment components while maintaining coaxial alignment functionality.
Solution Approach 2:
The flexible damping device performs multiple functions simultaneously: it provides coaxial alignment, absorbs torque fluctuations, dampens vibrations, and accommodates misalignment. This multi-functional design replaces several specialized components with a single device that handles all alignment and damping requirements.
2Stability of the object's composition
If conventional coaxial devices with multiple accessories are used, then coaxial alignment is achieved, but the weight of the device increases
Solution Approach 1:
By merging multiple heavy components into a single integrated flexible body with embedded damping elements, the overall weight is reduced. The unified structure eliminates redundant materials from separate joints, pins, nuts, and bushings while maintaining the necessary alignment and damping functions.
3Stability of the object's composition
If conventional coaxial devices with many components are used, then coaxial alignment is achieved, but the ease of manufacture decreases
Solution Approach 1:
The integrated design allows the flexible damping device to be manufactured as a single unit using techniques like rubber injection molding or composite fabrication, eliminating the need for assembling multiple precision components. This significantly simplifies the manufacturing process and reduces assembly steps.
Solution Approach 2:
The flexible body is designed with segmented damping elements that can be independently optimized during manufacturing while maintaining overall integration. This allows for modular manufacturing approaches that simplify production while preserving the unified structure's benefits.
4Stability of the object's composition
If elastomer is placed in sealed space formed by semi-coaxial devices, then coaxial alignment is achieved, but the reliability decreases due to elastomer deterioration
Solution Approach 1:
The elastomeric damping elements are extracted from sealed enclosed spaces and exposed to the environment through the flexible body's structure. This allows for better heat dissipation and prevents the accumulation of degradation products, extending the service life of the elastomer while maintaining alignment functionality.
5Stability of the object's composition
If conventional coaxial devices with many screws and screws holes are used, then coaxial alignment is achieved, but the manufacturing cost increases
Solution Approach 1:
By integrating all alignment and damping functions into a single device without separate fastening components, the bill of materials is significantly reduced. The elimination of numerous screws, nuts, and associated holes reduces both material costs and manufacturing complexity.

AI summary
A flexible shock-absorbing parts, suitable for use in a flexible damping device which connects and absorbs torque from two different mechanical shafts, so that they are coaxial during transmission. The flexible shock-absorbing parts is arranged between the two machines and closely attached to them; the flexible shock-absorbing parts are arranged radially on the first plane. The first plane is composed of the X-axis and the Y-axis in the Cartesian coordinate system. When the flexible shock-absorbing parts are installed in the vehicle, it allows the vehicle to absorb larger instantaneous external forces received by the wheels when the vehicle is travelling so that the impact of these external forces on the structure of the motor and the second gear inside the gear box can be reduced, thereby achieving protection for them.
