Integrated Support Gasket for Uniform Compression Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gaskets in lighting systems often compress unevenly, leading to weak seals that allow debris and moisture to enter joints, which can cause operational issues and joint failure.
Innovation Solution
A gasket with integrated structural supports, such as co-molded metallic inserts, is used to ensure uniform compression and maintain a consistent distance between mating surfaces, preventing over-compression and enhancing seal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional gasket is compressed between mating surfaces, then the gasket can form a seal, but the compression can be uneven or the mating surfaces can have geometries that cause the gasket to form a weak seal
Solution Approach 1:
The gasket incorporates rigid support regions at specific locations to provide localized structural reinforcement. These support regions compensate for uneven compression forces and geometric variations in mating surfaces, ensuring uniform seal contact pressure where needed most while maintaining overall seal integrity.
Solution Approach 2:
The gasket is constructed as a composite structure combining a compressible sealing material with embedded rigid support elements. This composite design allows the gasket to simultaneously provide compliance for sealing and structural rigidity for maintaining uniform compression, resolving the contradiction between seal formation and compression uniformity.
2Object-affected harmful factors
If the gasket is compressed to create a seal, then debris and moisture can be prevented from entering joints, but uneven compression can allow debris and moisture into the joints
Solution Approach 1:
Rigid support regions are strategically positioned within the gasket to maintain consistent seal pressure in critical areas. This localized reinforcement ensures that the seal remains effective and prevents harmful factors like debris and moisture from penetrating through weak points caused by uneven compression.
3Device complexity
If a gasket without structural support is used, then the device complexity is low, but the gasket can be compressed unevenly leading to weak seals
Solution Approach 1:
The rigid support elements are integrated directly into the gasket structure during manufacturing, merging the sealing function and structural support function into a single unified component. This integration eliminates the need for separate support structures while ensuring consistent seal performance, thus maintaining low device complexity while improving reliability.

AI summary
Certain aspects involve a lighting system including a compressible gasket. The gasket can include front and back surfaces and at least one substantially rigid support embedded within the gasket. The embedded support can be positioned within the gasket so as not to be exposed on the front or back surfaces of the gasket.
