Edgemount Inserts for Hidden Composite Panel Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for composite panels often require visible fasteners and lack efficient methods to secure inserts within recesses, leading to aesthetic and structural challenges.
Innovation Solution
A method and system involving inserts with recesses and epoxy encapsulation, where inserts are secured within recesses of composite panels using epoxy to create a flush and secure connection, allowing for hidden fasteners and enhanced structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional visible fasteners are used to connect composite panels, then structural strength is achieved, but aesthetic appearance deteriorates due to visible fasteners
Solution Approach 1:
The fastener mechanism is extracted and hidden within recesses in the panel surfaces. Inserts are placed inside recesses so that only minimal portions protrude, concealing the fastening mechanism from view while maintaining structural connection strength between panels.
Solution Approach 2:
The fastening system uses nested structures where inserts are placed within recesses, and fasteners are received within the inserts. This nested arrangement hides the fastening components within the panel thickness, achieving a flush appearance that prioritizes aesthetics while maintaining structural integrity.
2Productivity
If inserts are secured within recesses using mechanical methods only, then installation speed is improved, but reliability deteriorates due to insufficient securing
Solution Approach 1:
The securing method merges mechanical insertion with chemical bonding. Inserts are mechanically placed within recesses and then secured using epoxy adhesive, combining both mechanical positioning and chemical bonding for reliable attachment while maintaining efficient installation.
Solution Approach 2:
The securing system uses composite bonding approaches combining mechanical fit (physical structure) with epoxy adhesive (chemical bond). This composite securing method provides both immediate mechanical stability during installation and long-term reliable bonding.
3Strength
If epoxy is applied extensively to secure inserts, then bonding strength is improved, but material waste increases
Solution Approach 1:
Epoxy adhesive is applied locally at specific interfaces where bonding is required, rather than extensively throughout the entire insert-recess interface. The recess geometry and insert design concentrate the epoxy application to critical bonding zones, achieving sufficient bond strength while minimizing material usage and waste.

AI summary
Disclosed is a system for connecting an edge of one panel to an edge of a second panel. Recesses are formed into the edges of each panel, and two distinct inserts are pressed into and held within the recesses. The inserts include holes for receiving epoxy, and epoxy conducting shafts and circuits are formed on the outside of the inserts to assist in the encapsulation of the insert within each panel edge.
