Visual-Seal Fastening Clip for Flexible Installation Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening clips have predefined installation positions, which are unreliable and limiting, as they often rely on markings for visual indication of correct installation, leading to potential errors and restricted orientations.
Innovation Solution
A fastening clip with a seal that visually indicates its installed configuration through angular changes as it transitions from an uninstalled to an installed state, allowing for various installation orientations and providing clear visual confirmation of secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If predefined installation positions with markings are used, then visual indication of correct installation is provided, but installation flexibility and orientation freedom are restricted
Solution Approach 1:
The seal changes its visual appearance from a first color state to a second color state when transitioning from uninstalled to installed configuration. This color change provides reliable visual indication of correct installation without restricting installation orientations, as the seal can flex to any position around the collar perimeter while still providing visual confirmation when installed.
Solution Approach 2:
The seal is designed as a flexible component that can dynamically change its position and shape. In the uninstalled configuration, the seal resides in a first position around the collar. When the clip is installed, the seal flexes to a second position, potentially extending beyond the collar perimeter or changing its angular orientation, providing visual indication while allowing flexible installation positions.
2Loss of information
If a seal is designed to flex beyond the collar perimeter in installed configuration, then visual indication of installation is improved, but the seal structure complexity increases
Solution Approach 1:
The seal is implemented as a flexible membrane or thin-walled structure that can elastically deform. This flexible shell design allows the seal to extend beyond the collar perimeter when installed, providing clear visual indication, while maintaining a relatively simple overall structure that integrates with the collar. The flexibility is achieved through material selection and geometric design rather than complex mechanical mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clip ensures reliable visual indication of correct installation, reducing errors and allowing for flexible positioning, thereby enhancing the installation process and user confidence.
Implementation Method 1
the seal is configured to flex against an upper surface of the support structure in response to applied pressure between the seal and the support structure

AI summary
A fastening clip is provided for fastening to one or more support structures. The fastening clip includes a clip body and a seal. The seal is disposed around a peripheral edge of the clip body and includes a first end and a sealing foot, the first end engaging the clip body, the sealing foot projecting from the first end to a second end such that the second end is disposed radially outwardly from the first end, and the second end being radially aligned with or disposed radially inwardly from the peripheral edge of the collar in an uninstalled configuration. In an installed configuration, the circumferential seal is configured to flex against a support structure in response to applied pressure between the seal and the support structure so that the second end is disposed radially outwardly from the peripheral edge of the collar.
