Self-Securing Fastener Insert With On-Demand Adhesive Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of fastener-receiving inserts in composite panels is inefficient due to the need for a multi-step process with adhesive materials that have a short curing time, leading to potential wastage and excess adhesive application, which increases labor and equipment requirements.
Innovation Solution
A fastener-receiving insert system with adhesive-dispensing chambers and a puncturing device that releases the adhesive material upon installation, minimizing excess adhesive and simplifying the installation process by integrating the adhesive application directly into the insert system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive material is applied using a multi-step process with actuated adhesive materials, then the insert can be secured to the composite panel, but the installation time increases and adhesive wastage occurs due to short curing time and potential excess application
Solution Approach 1:
The adhesive material is pre-loaded into the adhesive-dispensing chamber of the insert before installation. This preliminary preparation eliminates the need for on-site adhesive mixing and application equipment, allowing the adhesive to be dispensed immediately upon insertion into the composite panel, thereby reducing installation time while ensuring proper bonding.
Solution Approach 2:
The insert is designed with integrated adhesive-dispensing chambers that automatically dispense the adhesive material when the insert is inserted into the composite panel. The system serves itself by incorporating the adhesive application function directly into the insert, eliminating the need for separate adhesive application equipment and reducing installation time.
2Reliability
If adhesive material is applied to ensure complete coverage, then adequate bondage is achieved, but adhesive wastage increases due to potential excess application
Solution Approach 1:
The adhesive material is contained within specific adhesive-dispensing chambers positioned at precise locations on the insert. These chambers are designed to dispense adhesive only where needed - specifically at the interface between the insert and the composite panel - ensuring complete coverage for adequate bonding while minimizing adhesive wastage by preventing excess application.
Solution Approach 2:
The adhesive material is pre-measured and pre-loaded into the adhesive-dispensing chambers during insert manufacturing. This preliminary action ensures that the exact amount of adhesive needed for complete coverage is provided, eliminating the need to apply excess adhesive to ensure adequate bonding and thereby reducing adhesive wastage.
3Reliability
If adhesive application equipment and multi-step process are used, then the insert can be secured, but labor and equipment requirements increase
Solution Approach 1:
The adhesive application function is merged with the insert itself by incorporating adhesive-dispensing chambers directly into the insert body. This integration combines the insert installation and adhesive application into a single operation, eliminating the need for separate adhesive application equipment and reducing labor requirements while ensuring reliable bonding.
Solution Approach 2:
The insert is designed to automatically dispense its own adhesive material through integrated adhesive-dispensing chambers when inserted into the composite panel. This self-service capability eliminates the need for external adhesive application equipment and multi-step processes, reducing both labor and equipment requirements while maintaining bond strength.

AI summary
A fastener-receiving insert system includes a fastener-receiving insert having a proximal end and a distal end and at least one adhesive-dispensing chamber adjacent to the distal end of the insert, containing at least one part of an adhesive material within a chamber wall. The fastener-receiving insert system further includes a puncturing device operably engaged with and configured to puncture the chamber wall to release the at least one part of the adhesive material around the fastener-receiving insert.
