Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid cable routing is used to maintain cable position, then cable stability is improved, but vibration damage to connectors and components increases
Solution Approach 1:
The patent employs a flexible retaining member with a C-shaped cross-section that envelops the electrical cables. This flexible structure allows the cables to move and vibrate without transmitting excessive forces to the connectors, while still providing adequate support and routing guidance. The flexibility of the retaining member absorbs vibration energy, preventing damage to connectors and electronic components.
Solution Approach 2:
The retaining system transitions from a rigid fixed structure to a dynamic flexible structure that can adapt to vibrations and relative movements. The flexible retaining member deforms elastically under vibration loads, allowing the system to accommodate dynamic movements between the electrical equipment and control unit while maintaining cable support.
2Reliability
If flexible cable routing is used to accommodate vibrations, then connector reliability is improved, but cable position control deteriorates
Solution Approach 1:
The C-shaped flexible retaining member provides a balance between flexibility and positional control. While allowing vibrations to pass through, the retaining member maintains the cables in a defined route, preventing excessive displacement and maintaining adequate cable position stability for reliable electrical connections.
3Strength
If rigid retaining structures are used to support cables, then cable support is improved, but vibration energy transmission to components increases
Solution Approach 1:
The flexible retaining member provides adequate cable support strength while simultaneously absorbing and damping vibration energy. The flexible material deforms under vibration loads, converting mechanical vibration energy into heat through internal friction, thereby reducing the transmission of harmful vibrations to connectors and electronic components.
Solution Approach 2:
The patent converts the harmful vibration energy into a beneficial damping effect. The flexible retaining member is designed to absorb and dissipate vibration energy through elastic deformation and internal friction, transforming the harmful mechanical vibrations into heat energy, thereby protecting the electrical connectors and components from vibration damage.
4Object-affected harmful factors
If flexible retaining members are used to dampen vibrations, then vibration damping is improved, but cable position control deteriorates
Solution Approach 1:
The C-shaped flexible retaining member maintains adequate cable position control while providing effective vibration damping. The geometric configuration and material properties of the flexible member are designed to provide sufficient stiffness for positional stability while maintaining flexibility for vibration absorption.
