Stud Pin Recessed Surface for Ice Powder Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional winter tires with stud pins face reduced grip on icy roads due to ice powder accumulation, which existing designs fail to adequately address.
Innovation Solution
A stud pin design featuring a tip with a recessed surface on the upper flange, inclined or curved to collect and prevent ice powder accumulation, combined with a pneumatic tire structure incorporating pin embedding holes and specific tread patterns to enhance ice contact and reduce powder buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stud pin is used on icy road surfaces, then grip is provided, but ice powder accumulates on the stud pin reducing its effectiveness
Solution Approach 1:
The invention extracts the harmful ice powder from the contact interface between the stud pin and road surface by providing grooves that collect and remove the powder, preventing it from interfering with the grip mechanism
Solution Approach 2:
The grooves act as an intermediary structure between the stud pin and the road surface, capturing and containing the ice powder in designated areas rather than allowing it to accumulate on the critical contact surfaces
2Object-generated harmful factors
If a recessed surface is added to the upper flange, then ice powder attachment is reduced, but device complexity increases
Solution Approach 1:
The upper flange is segmented into different functional zones including the recessed surface and grooves, with each segment serving a specific purpose in managing ice powder while maintaining overall structural integrity
Solution Approach 2:
The recessed surface is provided locally at specific positions on the upper flange where ice powder accumulation is most problematic, rather than modifying the entire structure, thus reducing complexity while maintaining effectiveness

AI summary
A stud pin includes a tip including a tip end surface configured to come into contact with a road surface and a trunk portion that supports the tip and extends in one direction. The trunk portion includes an upper flange disposed at a first end of the trunk portion, the tip being fixed to the upper flange, and a lower flange disposed at a position to a side opposite the upper flange of the trunk portion. An upper end surface of the upper flange from which the tip protrudes includes a recessed surface, the recessed surface including a smooth inclined surface recessing in a curved manner or a linear manner toward the lower flange with advancement toward a protruding base portion of the tip.
