Floor Access Panel Grounding Clip with Conductive Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access floor panel grounding solutions face challenges in achieving low electrical resistance due to paint barriers and ineffective brass strip implementations, which hinder efficient conductivity between the panel and the building ground.
Innovation Solution
A deformable metal clip is fastened to the floor panel, compressing against the stringer to establish electrical contact, allowing for efficient grounding by being designed to spring inwardly and outwardly without damage, ensuring reliable conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring clip is mounted to the stringer to make electrical contact to the floor panel, then electrical conductivity is improved, but the paint on the floor panel acts as a barrier increasing resistance
Solution Approach 1:
A conductive adhesive is introduced as an intermediary substance between the spring clip and the floor panel. The adhesive penetrates through the paint layer to establish direct electrical contact with the conductive core of the floor panel, thereby overcoming the insulating effect of the paint while maintaining mechanical bonding.
Solution Approach 2:
The invention replaces purely mechanical contact methods (which fail due to paint) with a chemical-mechanical bonding system. The conductive adhesive creates both mechanical attachment and electrical conductivity simultaneously, substituting the need for direct mechanical contact through the paint barrier.
2Reliability
If brass strips are laminated between the laminate top and bare panel to improve conductivity, then electrical contact is enhanced, but the panel paint must be scratched and brass strips must touch the stringers
Solution Approach 1:
The invention extracts the grounding function from complex multi-component assemblies (brass strips, paint scratching, alignment requirements) and consolidates it into a single spring clip component with integrated conductive adhesive, eliminating the need for manual paint removal and precise alignment.
Solution Approach 2:
The spring clip serves multiple functions simultaneously: mechanical attachment to the stringer, electrical contact through the conductive adhesive, and compliance with grounding requirements. This multi-functional design replaces the specialized brass strip system that required separate steps for paint removal and strip installation.
3Reliability
If a deformable metal clip is used to compress against the stringer for electrical contact, then grounding reliability is improved, but the clip must be designed to spring inwardly and outwardly without damage
Solution Approach 1:
The spring clip is designed with elastic deformation capabilities, allowing it to dynamically adjust to variations in stringer position, panel thickness, and installation tolerances. The clip's elastic properties enable it to maintain consistent contact force while accommodating dimensional variations without permanent deformation or failure.
