Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the insulator is fixed under the engine hood via adhesives or rivets, then the insulator is securely attached, but it becomes difficult to remove for maintenance and replacement
Solution Approach 1:
The patent employs dynamic fastening elements (clips) that can transition between engaged and disengaged states, allowing the insulator to be securely attached during operation but easily removed when needed. The clips are designed to snap into place for strong attachment yet can be conveniently released for maintenance.
Solution Approach 2:
The fastening system is divided into multiple discrete clips distributed across the insulator surface, rather than using a continuous adhesive or rivet pattern. This segmentation allows individual clips to be engaged or disengaged independently, facilitating easy removal and reinstallation of the insulator.
2Ease of operation
If through holes are formed in the insulator for mounting clips, then the insulator can be removably attached, but the insulating area is reduced and insulation performance is affected
Solution Approach 1:
The patent extracts the mounting function from the insulator body itself by providing separate mounting structures on the engine hood or surrounding components. The clips are positioned at the periphery or on the backside of the insulator, eliminating the need for through holes in the main insulating surface and preserving insulation performance.
Solution Approach 2:
The mounting holes are relocated from the face of the insulator to the periphery or backside, utilizing a different spatial dimension. This allows the clips to be mounted without penetrating the main insulating surface, thereby maintaining the integrity and effectiveness of the insulation area.
3Ease of operation
If through holes are formed in the insulator for mounting clips, then the insulator can be removably attached, but the appearance is affected due to uneven thickness
Solution Approach 1:
The mounting features are extracted from the visible surface of the insulator and placed on the periphery or backside. This ensures that the clips and mounting structures do not protrude from or create unevenness on the exterior surface, maintaining a smooth and aesthetically pleasing appearance.
4Ease of operation
If multiple clips are used to attach the insulator, then the insulator can be removably connected, but the production cost increases
Solution Approach 1:
The clips are designed as multi-functional elements that provide both attachment and positioning functions. Each clip serves multiple purposes: securing the insulator, providing alignment during installation, and enabling easy release. This consolidation of functions reduces the total number of components needed and simplifies the overall assembly process.
