Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-pressure air generation unit is attached on a panel constituting a back door or the like of a vehicle, then the device can remove foreign matters from the lens, but the versatility at the time of attaching the high-pressure air generation unit on the vehicle is lowered due to varying vehicle panel shapes
Solution Approach 1:
The adhesive member is designed with a plate-shaped flexible structure that can elastically deform to conform to various panel shapes. This flexible adhesive member allows the high-pressure air generation unit to be securely attached to panels with different curvatures and geometries, thereby maintaining attachment reliability across diverse vehicle types while improving versatility.
2Reliability
If the high-pressure air generation unit is securely attached to the vehicle panel, then the attachment reliability is improved, but abnormal noise due to resonance of the drive source operation may occur
Solution Approach 1:
The adhesive member is designed to provide vibration isolation between the high-pressure air generation unit and the vehicle panel. By selecting adhesive materials with appropriate damping characteristics, the system beforehand cushions against the transmission of vibrations from the drive source, preventing resonance-induced abnormal noise while maintaining secure attachment.
