Wiring Member Attachment Structure for Soft Base Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for attaching a wiring member to a vehicle body face challenges when the base member is soft, as they rely on the rigidity of the protection material, which can make attachment difficult.
Innovation Solution
A wiring member design that includes a base material attachment part capable of plastic deformation or elastic sandwiching to securely attach the wiring member to a soft base member, using snap fasteners that can be molded or deformed to fit around the base member from both sides, allowing for attachment even when the base member is soft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the second locking part of the clamp is locked to the protection material using rigidity of the protection material, then the clamp can be locked to rigid protection material, but it is hard to attach the clamp to soft protection material
Solution Approach 1:
The patent changes the attachment mechanism from rigidity-based locking to deformation-based sandwiching. The base material attachment part is designed to be plastically or elastically deformed to wrap around and sandwich the base member, adapting to both soft and rigid protection materials. This parameter change in the attachment mechanism enables versatility across different material hardness levels while maintaining secure attachment.
Solution Approach 2:
Instead of using the rigidity of the protection material to lock the clamp (conventional approach), the patent inverts the approach by using deformability of the base material attachment part to sandwich the base member. The attachment part actively deforms to conform to the base member rather than relying on the base member's rigidity to maintain the attachment.
2Reliability
If the base material attachment part is plastically deformed to sandwich the base member, then reliable attachment to soft base member is achieved, but the attachment part requires significant deformation capability
Solution Approach 1:
The patent utilizes plastic or elastic deformation parameters of the base material attachment part to achieve reliable attachment. By designing the attachment part with appropriate material properties and geometric features that enable controlled deformation, the system achieves secure sandwiching of the base member without requiring complex deformation mechanisms. The deformation capability is built into the attachment part's design rather than requiring additional mechanisms.
3Reliability
If the attaching member is designed to sandwich the base member from both sides, then secure attachment is achieved, but the attachment structure becomes more complex
Solution Approach 1:
The patent combines the base material attachment part and the attaching target attachment part into a single integrated attaching member. This merging of functions allows the attachment part to simultaneously sandwich the base member from both sides while also providing the attachment interface for the wiring body, reducing overall structural complexity compared to using separate components for each function.
Solution Approach 2:
The base material attachment part serves multiple functions: it sandwiches the base member from both sides for secure attachment, provides structural support, and integrates with the attaching target attachment part. This multi-functionality reduces the need for additional components while achieving reliable attachment security.
