Conductive Raised Floor Edge Strip for Creaking Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge strips for raised floors suffer from creaking noises due to relative movement of elements and require additional processing steps for conductivity and electrostatic discharge, which can cause noise and wear.
Innovation Solution
An edge strip composed of a thermoplastic material with a conductivity additive, such as carbon black, and a tribology additive, like polyketone or UHMW polyethylene, is manufactured by combining these components without additional processing steps, ensuring improved conductivity and reduced creaking.

Engineering Contradiction Analysis
1Object-generated harmful factors
If graphite is added to the edge strip material to reduce creaking, then sliding ease is improved, but electrical conductivity may be compromised
Solution Approach 1:
The patent uses a composite material system consisting of thermoplastic base material, carbon black conductivity additive (5-20 wt%), and polyketone tribology additive (3-15 wt%). This composite formulation simultaneously achieves electrical conductivity (surface resistance 10^4-10^6 Ω) and reduced creaking behavior through optimized friction properties, resolving the contradiction between conductivity and noise reduction.
Solution Approach 2:
The patent optimizes the concentration parameters of additives: carbon black at 5-20 wt% for conductivity and polyketone at 3-15 wt% for tribological performance. By precisely controlling these compositional parameters, the edge strip achieves both electrical conductivity and reduced creaking without compromising either property.
2Reliability
If multiple additives are added to improve conductivity and creaking behavior, then performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines conductivity and tribology additives into a single thermoplastic compound formulation that is processed in one extrusion step. The edge strip is manufactured by extruding the compound and forming it to dimensions, eliminating the need for separate coating or treatment steps, thus simplifying manufacturing while achieving both conductivity and noise reduction.
Solution Approach 2:
The thermoplastic compound serves multiple functions simultaneously: it provides structural integrity, electrical conductivity through carbon black, and reduced creaking through polyketone. This multi-functional material eliminates the need for separate components or processing steps for each function.
3Ease of manufacture
If conventional thermoplastic materials are used for edge strips, then ease of manufacture is maintained, but electrostatic charge dissipation is insufficient
Solution Approach 1:
The edge strip material is self-sufficient in providing both structural and functional properties. The carbon black additive inherently provides electrical conductivity for electrostatic discharge without requiring external grounding systems or additional components, while the thermoplastic base material maintains ease of manufacturing through conventional extrusion processes.
