Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If audio actuators are mounted directly to vehicle body components, then installation is simple, but acoustic performance and vibration radiation are compromised
Solution Approach 1:
A bridging bracket is introduced as an intermediary component between the audio actuator and the vehicle body component. The bracket includes a mounting platform that couples to the audio actuator and legs that couple to the vehicle body component, enabling proper vibration transmission while simplifying the overall mounting process through a standardized interface
Solution Approach 2:
The bridging bracket utilizes composite material construction, combining rigid sections for structural support with polymeric bushings for vibration isolation and acoustic coupling. This composite approach optimizes both mechanical strength and acoustic performance
2Stability of the object's composition
If rigid mounting is used for audio actuators, then structural stability is improved, but vibration transmission and sound radiation are reduced
Solution Approach 1:
The bridging bracket applies local quality differentiation by using rigid materials in the mounting platform and leg structures for stability, while incorporating polymeric bushings at specific contact points with the audio actuator to enhance vibration transmission and acoustic coupling where needed
3Reliability
If complex mounting structures are used, then acoustic and operational requirements are met, but device complexity and assembly difficulty increase
Solution Approach 1:
The bridging bracket is designed as a universal mounting solution that integrates multiple functions: structural support, vibration transmission, acoustic coupling, and positioning. This multi-functional design meets acoustic and operational requirements while avoiding the need for multiple separate components
