Two-Piece Clip for Vehicle Panel Sealing and Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-piece clips for securing elements together often damage the elements they connect and are not suitable for applications where sealing against liquids is required, particularly when used to secure a panel to a vehicle frame.
Innovation Solution
A two-piece clip design featuring a first component with a head and shaft, and a second component that provides a support surface for the head's contact surface, allowing for spring-preloaded protrusions to reduce damage and enable sealing, with the second component optionally having an opening for the shaft to enhance fixation and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-piece metal clip is used to secure elements together, then the clip provides strong fastening capability, but the metal element damages one of the elements being secured
Solution Approach 1:
The clip is divided into two separate components: a first component (metal clip with head and shaft) and a second component (support element). This segmentation allows the metal clip to provide fastening strength while the support component prevents damage to the secured elements, resolving the contradiction between fastening capability and element protection.
Solution Approach 2:
The second component acts as an intermediary between the metal clip and the element being secured. It mediates the contact interface, allowing the metal clip to apply fastening force while the support component protects the element from damage, thus resolving the harm caused by direct metal contact.
2Strength
If a single-piece metal clip is used for securing panels to vehicle frames, then the clip provides structural fastening, but it cannot seal against liquid ingress
Solution Approach 1:
By separating the clip into two components, the invention allows the first component to specialize in structural fastening while the second component specializes in sealing. The second component can be designed with sealing features (such as sealing rings or sealing surfaces) that the single-piece metal clip cannot provide, thus achieving both structural integrity and sealing reliability.
Solution Approach 2:
The two components can be made from different materials optimized for their specific functions. The first component uses metal for structural strength, while the second component can use elastomeric or polymer materials with sealing properties, creating a composite fastening system that provides both structural fastening and sealing capability.

Function Achieved in This Case
The two-piece clip design reduces the risk of damaging connected elements and allows for effective sealing, providing a secure and reliable attachment while preventing liquid ingress, making it suitable for applications like securing panels to vehicle frames.
Implementation Method 1
The protrusion may be spring-preloaded in the direction perpendicular to the shaft axis

AI summary
A two-piece clip for securing an element to another element includes a first component having a head and a shaft extending from the head along a shaft axis having a point. At least one protrusion is provided on the shaft, having a contact surface facing the head, and the head having a contact surface facing the protrusion. The clip further includes a second component having a support surface facing the contact surface of the head, and a contact surface facing the protrusion. The contact surface of the head is supported on the support surface of the second component.
