Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection is used to connect components, then the connection strength is improved, but noise and vibration transmission increases
Solution Approach 1:
The patent changes the mechanical parameter of the connecting member from rigid to resilient, allowing it to deform elastically under load. This enables the connection to maintain strength while absorbing vibrational energy and reducing noise transmission through the resilient deformation capability of the connecting member.
Solution Approach 2:
The resilient connecting member acts as a pre-configured cushioning element that absorbs and dampens vibrations and shocks before they can be transmitted between components. The elastic properties of the connecting member provide inherent vibration isolation and noise reduction while maintaining structural integrity.
2Stability of the object's composition
If a rigid connection is used, then the structural stability is improved, but the stress magnitude on the clip increases
Solution Approach 1:
The patent transforms the connecting member from a rigid structural element to a resilient one with elastic deformation capability. This allows the member to absorb stress through elastic deformation while maintaining structural stability, thereby reducing the peak stress magnitudes experienced by the clip during impact and vibration events.
Solution Approach 2:
The resilient connecting member serves as a stress-absorbing cushion that mitigates impact loads and vibration stresses before they can be fully transmitted through the clip structure. This protective function reduces the effective stress magnitude on the clip while preserving overall structural stability.
3Object-generated harmful factors
If a resilient connection is used, then noise and vibration transmission is reduced, but the connection strength decreases
Solution Approach 1:
The patent optimizes the resilient properties of the connecting member to achieve a balance between vibration isolation and connection strength. By carefully designing the elastic characteristics of the connecting member, the system maintains sufficient connection strength while effectively reducing noise and vibration transmission through controlled resilient deformation.

AI summary
A clip is structured for coupling together a first component and a second component. The clip includes a body portion and an opposing wall residing opposite and spaced apart from the body portion. At least one connecting member spans a space between the body portion and the opposing wall to connect the body portion and the opposing wall. The at least one connecting member is structured to enable resilient movement of each of the body portion and the opposing wall with respect to the other one of the body portion and the opposing wall responsive to a force acting on the body portion and/or a force acting on the opposing wall.
