Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the circuit is externally mounted to the vehicle to add functions, then the circuit can be retrofitted to the vehicle, but the circuit may fail due to vibrations transmitted from the vehicle
Solution Approach 1:
A vibration-proof member is introduced as an intermediary component between the housing and the vehicle. This mediator absorbs and dampens vibrations transmitted from the vehicle, preventing them from reaching the circuit while still allowing the circuit to be externally mounted for function addition.
Solution Approach 2:
The vibration-proof member is installed in advance between the housing and vehicle to preemptively cushion against vibrations. This prior cushioning prevents vibration-induced failures before they occur, ensuring circuit reliability while maintaining external mountability.
2Stability of the object's composition
If the circuit is fixed to the vehicle, then the circuit can be securely mounted, but vibrations from the vehicle may cause faults in the circuit
Solution Approach 1:
The vibration-proof member serves as a mediator that decouples the housing from direct rigid contact with the vehicle. This allows the housing to be stably mounted while the vibration-proof member filters out harmful vibrations, preventing circuit faults.
Solution Approach 2:
The vibration-proof member changes the mechanical parameters of the mounting system by introducing vibration-damping properties. It transforms the rigid connection into a compliant connection that maintains stability while reducing vibration transmission to the circuit.
3Reliability
If vibration-proof members are provided between the housing and vehicle, then vibrations are dampened and circuit faults are suppressed, but the device complexity increases
Solution Approach 1:
The vibration-proof member is designed as a simple, inexpensive component that can be easily replaced if needed. This approach manages complexity by using a basic damping element rather than a complex active vibration control system.
Solution Approach 2:
The vibration-proof member is designed as a replaceable component that can be discarded and replaced without affecting the core circuit or housing. This simplifies the overall system by making the vibration protection a maintainable accessory rather than an integrated complex system.
