Shoe Tread Pattern with Nested V-Shaped Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many shoe treads are poorly designed, leading to inadequate comfort and traction, which can result in discomfort, increased effort to maintain balance, and a higher risk of slipping.
Innovation Solution
A shoe tread pattern comprising a plurality of V-shaped tread members arranged in nested rows on the outsole, providing improved comfort and grip through varied thicknesses and orientations of the tread members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the tread lacks grooves, patterns, or depth, then the shoe construction is simpler, but the surface grip is inadequate
Solution Approach 1:
The tread is segmented into multiple grooves and patterns including circumferential grooves, radial grooves, and siping that divide the continuous tread surface into discrete functional elements. This segmentation creates multiple contact points and channels for water/ejecta removal, improving surface grip without requiring excessive overall tread depth or complexity.
Solution Approach 2:
Different regions of the tread are designed with locally optimized characteristics - the circumferential grooves provide primary water channels, radial grooves provide secondary channels and structural support, and siping provide micro-level contact enhancement. Each local area performs a specific function contributing to overall grip performance.
2Ease of manufacture
If the tread depth is inadequate, then the manufacturing is simpler, but the shock absorption capability is limited
Solution Approach 1:
The tread design employs nested grooves where radial grooves are positioned within the valleys of circumferential grooves, and siping are embedded within the tread blocks. This nested arrangement maximizes the functional depth and shock-absorbing capacity within the available tread depth, allowing effective shock absorption without requiring excessive material removal or complex multi-layer construction.
Solution Approach 2:
The tread design utilizes multiple dimensions of groove arrangement - circumferential grooves run around the shoe, radial grooves extend from the center outward, and siping provide cross-hatching patterns. This multi-dimensional groove system creates a three-dimensional shock absorption network that dissipates impact forces through various pathways without requiring increased single-direction depth.
3Device complexity
If the spacing between tread features is sub-optimal, then the design is simpler, but the weight distribution is poor causing localized high-pressure points
Solution Approach 1:
The tread design merges multiple groove types (circumferential, radial, and siping) into an integrated pattern where they work together to distribute weight. The circumferential grooves handle lateral weight distribution, radial grooves manage fore-aft distribution, and siping provide localized pressure points. This combined approach achieves uniform weight distribution without requiring complex independent adjustment of each groove system.
Solution Approach 2:
The tread pattern is designed to dynamically adapt to walking conditions - the grooves flex and deform under load to optimize contact distribution. The spacing and depth of grooves are designed to allow dynamic adjustment of pressure points during the gait cycle, distributing weight evenly across the foot as the shoe flexes during movement rather than maintaining rigid fixed pressure points.

AI summary
A tread pattern for a shoe is provided that improves the comfort, grip, and/or other aspects of the shoe as perceived by a consumer when the shoe is worn. The tread pattern comprises a plurality of tread members positioned on at least a portion of the bottom surface of the outsole of the shoe. In some instances, the plurality of tread members may be arranged in nested rows to form the tread pattern. In other instances, the plurality of tread members may be arranged in other configurations to form different tread patterns. Additionally, the tread members may be substantially V-shaped and include a first arm, a second arm, and a vertex. Each tread members may be contoured such that at least a portion of the tread member protrudes a greater distance from the bottom surface of the outsole of the shoe than at least another portion of the tread member.
