Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid mounting systems are used to secure circuit boards, then mechanical strength and stability are improved, but vulnerability to shock and vibration increases
Solution Approach 1:
The patent changes the mechanical parameters of the mounting system by using spring elements instead of rigid mounts. The spring constant and damping coefficients are optimized to provide both structural support and vibration isolation, transforming the system from rigid to compliant while maintaining strength
Solution Approach 2:
The mounting system combines spring elements with damping materials to create a composite structure that simultaneously provides mechanical support and shock absorption. This composite approach allows the system to maintain strength while reducing vulnerability to harmful vibrations
2Object-affected harmful factors
If spring elements are used to reduce shock and vibration, then vibration isolation is improved, but mechanical support capability deteriorates
Solution Approach 1:
The patent merges spring elements with damping elements into a unified mounting system. The spring component provides mechanical support and elasticity, while the damping component suppresses vibrations. This combination allows the system to simultaneously achieve both vibration isolation and adequate mechanical support capability
3Adaptability or versatility
If multiple separate components are used for spring and damper systems, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines spring elements and damper elements into an integrated mounting system that can be attached as a single assembly to the circuit board. This integration maintains the distinct functional properties of springs and dampers while reducing the number of separate components and simplifying the installation process
Solution Approach 2:
The mounting system is designed as a universal solution that can be applied to various circuit board configurations and mounting scenarios. The standardized design allows the same basic structure to serve multiple functions across different applications, reducing overall system complexity while maintaining versatility
