Graphene Wax Chain Coating for Dirt-Resistant Off-Road Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycle and motorbike chains experience undesirable lengthening due to dirt accumulation in off-road environments, leading to increased friction and reduced durability, as existing lubricants fail to effectively protect against dirt and maintain optimal chain condition.
Innovation Solution
A composition comprising more than 10% solvent, 5-65% wax, and 0.005-10% graphene is applied to the chain, which, upon evaporation of the solvent, leaves a wax layer with entrapped graphene, providing protection against dirt and reducing chain lengthening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oil-based lubricants are applied to the chain, then metal-to-metal contact is smoothed, but dirt accumulates rapidly creating abrasive paste that compromises chain durability
Solution Approach 1:
The patent changes the physical and chemical parameters of the lubricant by using a solvent-based formulation with specific viscosity characteristics that allow the lubricant to remain liquid during application but evaporate quickly afterward, leaving minimal residue that attracts less dirt
Solution Approach 2:
The patent employs a volatile solvent carrier that temporarily carries the lubricating components during application but then evaporates completely, leaving only the active lubricating substances. This short-lived carrier approach minimizes persistent residue that would otherwise attract and hold dirt particles
2Reliability
If aqueous-based wax lubricants are applied to the chain, then some drying occurs leaving a wax layer, but the layer remains sticky and collects dirt
Solution Approach 1:
The patent changes the solvent base from aqueous to organic volatile solvents, fundamentally altering the evaporation characteristics and residue properties. This parameter change enables complete evaporation without leaving sticky residues that attract dirt
Solution Approach 2:
The patent uses volatile organic solvents as temporary carriers that evaporate completely after application. These short-lived solvent molecules deliver the lubricating components and then disappear entirely, leaving no persistent sticky layer to collect dirt particles
3Reliability
If dry lube with solvent and ceramic powder is applied to the chain, then lubrication is provided, but wind and chain movement quickly remove the additive
Solution Approach 1:
The patent creates a composite lubricating system combining multiple components (solvent, wax, PTFE, and ceramic particles) that work synergistically. The ceramic particles are embedded within a matrix of wax and PTFE, creating a composite structure that adheres better to the chain while providing sustained lubrication
Solution Approach 2:
The patent structures the lubricant composition with ceramic particles nested within a matrix of wax and PTFE, which itself is carried by the solvent. This nested structure allows the smaller ceramic particles to be protected and retained by the larger wax-PTFE matrix, preventing premature removal by wind and chain movement
4Reliability
If molten wax bath treatment is applied to the chain, then a thin layer of solid wax is left for lubrication, but the chain must be removed from the bike frequently for reapplication
Solution Approach 1:
The patent replaces the mechanical/thermal process of molten wax bathing (requiring heating equipment and chain removal) with a simple liquid application process. The solvent-based lubricant is applied in liquid form and dries naturally, eliminating the need for complex heating apparatus and chain removal procedures
Solution Approach 2:
The patent changes the application temperature parameter from high temperature (molten wax at 150°C) to ambient temperature. This parameter change allows the lubricant to be applied in liquid form directly to the chain while on the bike, eliminating the need for heating and chain removal
