Conical Aggregate for Ice Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for enhancing traction on icy and wet surfaces, such as using sand, gravel, or salt, are inefficient due to irregular forms and slow melting rates, leading to inadequate friction and safety issues for vehicles and pedestrians.
Innovation Solution
A traction-enhancing aggregate with a symmetrical, conically shaped body and centralized masses on both top and bottom surfaces, designed to penetrate surfaces effectively, providing immediate traction enhancement without dissolving quickly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sand or gravel is used to increase friction on icy surfaces, then the coefficient of friction is improved, but the effectiveness is reduced because irregular shapes cause planar sides to contact ice instead of vertex points biting into the surface
Solution Approach 1:
The aggregate is designed with intentional asymmetry in the form of protruding masses with vertex points that are asymmetric relative to the body, ensuring that these pointed features contact the ice surface first and bite into it, rather than planar sides making contact
Solution Approach 2:
The aggregate features curved or rounded vertex points on the protruding masses rather than sharp angles, which allows for more consistent contact with the ice surface while maintaining the biting capability, and the overall body may have rounded contours that facilitate uniform distribution
2Reliability
If salt is used to melt ice, then the ice surface is exposed, but the effect is not immediate and becomes ineffective once the salt fully dissolves
Solution Approach 1:
The aggregate is designed to immediately mechanically penetrate and fracture the ice surface upon contact, providing instant traction enhancement before any chemical melting action occurs, rather than waiting for dissolution to begin the process
Solution Approach 2:
The invention replaces the purely chemical melting mechanism of salt with a mechanical fracture and penetration mechanism using protruding masses that physically break and bite into the ice, providing immediate structural disruption and traction
3Reliability
If regular aggregates are used on wet surfaces, then some friction is provided, but the liquid film barrier causes loss of traction or hydroplaning
Solution Approach 1:
The aggregate body is segmented into multiple protruding masses distributed across the surface, creating numerous discrete contact points that collectively penetrate the liquid film barrier and establish direct solid-to-solid contact with the underlying surface
Solution Approach 2:
The protruding masses extend the aggregate structure into a third dimension perpendicular to the base surface, allowing the vertex points to reach through the liquid film barrier that forms on wet surfaces and establish contact with the substrate beneath the fluid layer

AI summary
A traction enhancing aggregate is provided comprised of a body with a side having a top and bottom with each having three or more protruding conical masses with axes positioned about a circular centerline and made from moldable material capable of being delivered by hand or traction enhancing system to a lower surface such as ground to provide an increased coefficient of friction between an upper surface such as a shoe or tire and a lower surface.
