Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid attachment structure is used to secure auxiliary components, then the attachment strength is improved, but the structure becomes prone to unintentional detachment due to vibrations
Solution Approach 1:
The patent applies the dynamics principle by introducing an elastic structure (spring) that allows dynamic movement between the first and second structures. This elastic connection enables the attachment to adapt to vibrations and mechanical movements, preventing unintentional detachment while maintaining secure attachment. The spring can compress and extend in response to vibrational forces, absorbing energy and preventing the rigid connection from failing.
2Object-affected harmful factors
If the elastic structure allows axial movement between structures, then vibration damping is improved, but the connection flexibility increases
Solution Approach 1:
The patent applies parameter changes by utilizing the elastic properties of the spring structure. The spring's material and geometric parameters (such as wire diameter, coil density, and length) are designed to provide specific vibration damping characteristics. By adjusting these parameters, the system achieves optimal vibration absorption while maintaining appropriate connection flexibility. The elastic structure's ability to deform and recover maintains a balance between damping performance and connection stability.
