Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid material spokes (e.g., steel) are used, then strength and rigidity are sufficient, but the spokes deform and weaken under heavy impacts, leading to safety issues and increased maintenance
Solution Approach 1:
The patent changes the material parameters from rigid metal to flexible textile fiber, fundamentally altering the mechanical properties. The textile fiber spoke rope exhibits different stress-strain characteristics with higher elasticity and energy absorption capacity, allowing it to withstand heavy impacts without permanent deformation while maintaining strength
Solution Approach 2:
The spoke is constructed as a composite structure with textile fiber ropes braided together and encased in a protective sheath. This composite design combines the high strength-to-weight ratio of textile fibers with the protective function of the sheath, achieving both impact resistance and durability
2Stability of the object's composition
If traditional rigid spokes are used, then structural stability is maintained, but they cannot absorb impact energy, resulting in irreversible deformation
Solution Approach 1:
The textile fiber spoke rope inherently possesses elastic properties that provide beforehand cushioning against impact forces. The material's natural elasticity allows it to deform elastically during impact and return to its original state, preventing the irreversible deformation that occurs with rigid materials
Solution Approach 2:
The patent employs flexible textile fiber ropes as the core structural element, replacing rigid metal spokes. The flexible nature of the textile fibers allows for energy absorption through elastic deformation while maintaining structural integrity, effectively cushioning against impact forces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The textile fiber spoke rope maintains its original characteristics under extreme impacts, reducing failure rates, ensuring riding safety, and lowering maintenance and cost requirements.
Implementation Method 1
the flexibility and strength margin of the spoke rope itself, so that the original characteristics of the spoke rope can still be kept under an extreme impact force without irreversible deformation
Implementation Method 2
the pressing opening forms a closed compact structure by means of an adhesive and pressing of a machine platform

AI summary
Provided is a rim spoke, including a spoke rope and nipples. Mounting heads are fixedly sleeved on both ends of the spoke rope; through mounting holes are formed in the nipples; the nipples are fixedly sleeved on the mounting heads by means of the mounting holes; and the spoke rope is made of a textile fiber material. When the textile fiber spoke rope in a high tension state is subjected to a heavy impact, part of an impact force is cushioned due to the flexibility and strength margin of the spoke rope itself, so that the original characteristics of the spoke rope can still be kept under an extreme impact force without irreversible deformation, thereby reducing riding failure rate of riding, ensuring the riding safety, reducing the daily maintenance requirement of a wheel, and reducing costs.
