Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners are used to secure wiring harnesses to the structure, then the wiring harness is securely attached, but holes must be drilled in the structure which limits flexibility and causes corrosion
Solution Approach 1:
The invention extracts the fastener from the mounting system and replaces it with an adhesive system. The adhesive is applied to a carrier that is then attached to the structure, eliminating the need for holes and fasteners while maintaining secure attachment and improving mounting flexibility.
Solution Approach 2:
The invention replaces the mechanical fastening system (holes and fasteners) with an adhesive bonding system. The adhesive provides the securing function without requiring mechanical penetration of the structure, thereby eliminating corrosion risks and improving adaptability.
2Reliability
If fasteners are used to secure wiring harnesses, then the wiring harness is securely attached, but multiple manufacturing steps are required to prepare holes
Solution Approach 1:
The invention removes the hole preparation step from the manufacturing process by replacing mechanical fasteners with adhesive bonding. The adhesive system can be applied directly to the structure surface without requiring drilling, punching, or other hole preparation operations.
Solution Approach 2:
The mechanical hole preparation and fastening process is replaced with an adhesive application process. This substitution eliminates multiple manufacturing steps including drilling, deburring, and fastener installation, simplifying the overall manufacturing process while maintaining secure attachment.
3Reliability
If fasteners are used with fixed locations and orientations, then the wiring harness is securely attached, but substantial coordination, inspection, testing and re-work expenses are incurred
Solution Approach 1:
The invention introduces flexibility and adjustability to the mounting system. The adhesive carrier can be positioned and oriented freely on the structure surface, allowing for dynamic adjustment during assembly rather than being constrained to fixed predetermined locations and orientations.
Solution Approach 2:
The invention changes the mounting parameters from fixed discrete locations to continuous adjustable positions. The adhesive system allows the wiring harness to be mounted at any location within the adhesive's bonding area, providing continuous positional adjustment rather than discrete fixed points.
4Reliability
If holes are drilled in the structure for fasteners, then the wiring harness is securely attached, but opportunities for rust and corrosion are created
Solution Approach 1:
The invention extracts the hole-creating fastening method and replaces it with surface bonding. By removing the need for holes, the invention eliminates the primary pathway for moisture and corrosive agents to penetrate the structure, thereby preventing corrosion while maintaining secure attachment.
Solution Approach 2:
The mechanical penetration system is replaced with a surface bonding system. The adhesive bonds to the surface without penetrating it, eliminating the creation of holes that would otherwise serve as corrosion pathways while providing equivalent or superior attachment reliability.

Function Achieved in This Case
This solution reduces manufacturing waste and costs by allowing flexible placement of wiring harnesses, avoiding corrosion, and minimizing rework and inspection expenses, while maintaining secure attachment of the harnesses.
Implementation Method 1
Pressure sensitive adhesive disposed on one side of the two opposing end portions of the carrier selectably secures each of the two end portions and hence the loop and object to a support surface

AI summary
An adhesive system comprises a carrier and an adhesive for attaching objects, such as a wiring harness, to a support surface, such as the structure of a motor vehicle, aircraft or appliance. The adhesive system features two end portions and a strap portion. An opening in one end portion is configured to receive the other end portion. The opening has a width normal to the longitudinal axis of the carrier that is configured to receive the strap portion of the carrier to define a loop. The carrier may be configured so that the loop maintains a closed condition about an object. Pressure sensitive adhesive disposed on one side of the end portions allows the carrier to be securely attached to a support surface.
