Integrated Panel Fastener for Close Blind Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening techniques for automotive components require separate fasteners, which complicate assembly and do not allow for close positioning of panels, lacking reliability and efficiency in blind, close-panel assemblies.
Innovation Solution
An integrated fastener system where the fastener is fabricated as a unitary structure with the component, using additive manufacturing techniques, allowing for improved assembly characteristics and reduced part numbers by eliminating the need for separate fasteners and clip-attachment structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fasteners and clip-attachment structures are used, then reliable fastening is achieved, but assembly complexity increases and panel positioning distance increases
Solution Approach 1:
The patent combines the fastener and the panel into a single integrated component. The fastener is formed as an integral part of the panel during the panel manufacturing process, eliminating the need for separate fastener components and clip-attachment structures. This merging reduces assembly complexity while maintaining fastening reliability through the integrated design.
2Reliability
If separate fasteners are used, then secure fastening is achieved, but assembly time and manufacturing cost increase
Solution Approach 1:
The fastener is pre-formed as an integral part of the panel during panel manufacturing, before the final assembly operation. This preliminary action of integrating the fastener into the panel structure eliminates the need for separate fastener installation steps during assembly, thereby improving assembly efficiency while ensuring secure fastening through the pre-integrated design.
3Strength
If traditional fasteners are used, then connection strength is achieved, but panel positioning distance increases
Solution Approach 1:
By merging the fastener with the panel structure, the patent eliminates the need for separate fastener components that would increase the distance between panels. The integrated fastener allows for closer panel positioning while maintaining connection strength through the direct integration of the fastening feature into the panel itself.

AI summary
Disclosed are systems and methods for coupling a first component to a second component via an integrated fastener. The component assembly includes a first component having a first surface and a second surface. An integrated fastener extending from the second surface and configured to attach the first component adjacent to the second component. The first component and the integrated fastener are formed as a unitary structure using, for example, an additive manufacturing process. The integrated fastener can include a clip assembly with one or more retention features extending outwardly from the integrated fastener at an end opposite the first component.
