Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vibration reduction structures (spring, wire rope, hydraulic) are used, then vibration protection is provided, but the structure becomes complex and occupies significant space
Solution Approach 1:
The patent combines the vibration reduction function with the mounting bracket structure itself. The inverted U-shaped bracket directly connects to the electronic device and vehicle body, eliminating the need for separate vibration reduction components while maintaining protection functionality.
Solution Approach 2:
The mounting bracket serves multiple functions: structural support, vibration reduction, and impact protection. This multi-functional design simplifies the overall structure by eliminating dedicated vibration reduction components while maintaining all necessary protection functions.
2Reliability
If traditional vibration reduction structures are used, then vibration protection is provided, but the service life is short
Solution Approach 1:
The patent changes the material parameter from traditional rigid or semi-rigid vibration reduction materials to elastomeric material with specific durometer hardness (40-70 Shore A). This material parameter change provides both vibration protection and enhanced durability with resistance to aging, cracking, and degradation.
Solution Approach 2:
The patent uses composite construction combining the elastomeric material with reinforcing elements (fabric layers or metal inserts) to create a mounting bracket that maintains flexibility for vibration reduction while gaining structural strength and longevity for extended service life.
3Reliability
If traditional vibration reduction devices are used, then some protection is provided, but they are not suitable for varying load conditions
Solution Approach 1:
The elastomeric material provides dynamic adaptation to varying loads through its inherent viscoelastic properties. The material automatically adjusts its stiffness and damping characteristics based on the applied load, providing optimal vibration protection across different operating conditions without requiring adjustment mechanisms.
4Device complexity
If simple structure is used, then space is minimized and installation is simplified, but vibration reduction effectiveness may be compromised
Solution Approach 1:
The patent employs an elastomeric mounting bracket that functions as a flexible structural element. This flexible design provides effective vibration isolation while maintaining a simple, space-efficient structure that is easier to install than rigid vibration reduction systems.
