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 to reduce part numbers and assembly complexity, allowing for close panel positioning and secure attachment without additional clip-attachment structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate fasteners are used, then fastening function is provided, but assembly complexity increases and panel positioning distance increases
Solution Approach 1:
The fastener is merged with the primary panel to form an integrated fastener system. The fastener becomes a unitary structure with the primary panel, eliminating the need for separate fastener components and reducing assembly complexity while maintaining fastening reliability through the integrated design
2Productivity
If traditional separate fasteners with clip-attachment structures are used, then secure fastening is achieved, but number of parts increases and assembly time increases
Solution Approach 1:
The fastener and primary panel are combined into a single integrated component, reducing the total number of parts. The unitary structure eliminates the need for separate clip-attachment structures, thereby improving assembly efficiency and productivity
3Ease of manufacture
If integrated fastener is used, then assembly is simplified and part complexity is reduced, but manufacturing process complexity increases
Solution Approach 1:
The manufacturing process utilizes additive manufacturing technology, which changes the manufacturing approach from traditional subtractive or formative methods. This parameter change in the manufacturing process enables the creation of complex integrated geometries that would be difficult or impossible to achieve with conventional manufacturing, thereby simplifying assembly while managing manufacturing complexity through advanced fabrication

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.
