Textile Outsole Connection Without Bonding Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunctional outdoor shoes, such as mountain and trail running shoes, face challenges in providing comfort and durability while maintaining stability and traction, especially during prolonged wear, due to the limitations of existing sole connections and manufacturing processes that often require additional binders and may use environmentally hazardous substances.
Innovation Solution
A shoe design featuring a textile two-dimensional region connected to the shoe upper and an outsole unit with vulcanized rubber, forming a mechanical and chemical connection without bonding agents, enhancing durability and stability while allowing for breathability and water resistance, and incorporating varying rubber materials for improved traction and abrasion resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vulcanized rubber is used for outsoles to provide good elasticity, traction, and abrasion resistance, then the durability and traction are improved, but the manufacturing complexity increases due to the need for additional binders and bonding agents
Solution Approach 1:
The patent merges the outsole and upper into a single integrated component by molding the rubber material directly onto the textile region. This eliminates the need for separate bonding processes and additional binders, resolving the contradiction between durability and manufacturing complexity.
Solution Approach 2:
The textile two-dimensional region is prepared in advance with specific structural features (loops, pores, or textured surfaces) that enable direct mechanical interlocking with the rubber material. This preliminary preparation allows the rubber to bond directly without additional chemical binders, simplifying manufacturing while maintaining durability.
2Reliability
If the shoe upper is comprised from rubber to provide durability and protection, then the protective function is improved, but the comfort deteriorates due to excessive sweating and poor breathability
Solution Approach 1:
The patent uses a composite structure combining rubber material for the outsole ( providing protection and durability) with a textile two-dimensional region for the upper (providing breathability and comfort). This material combination resolves the contradiction between protective function and comfort by assigning different materials to different functional requirements.
Solution Approach 2:
Different regions of the shoe are assigned different material properties: the outsole uses rubber for protection and abrasion resistance, while the upper uses breathable textile for comfort. This local differentiation of material quality allows each region to optimize its specific function without compromising the other.
3Ease of manufacture
If the connection of the shoe upper to the sole exists only in individual regions along the rim to simplify manufacturing, then the ease of manufacture is improved, but the stability deteriorates for climbing activities
Solution Approach 1:
The patent merges the connection from discrete rim-point attachments into a continuous integrated structure where the rubber material is molded directly onto the entire textile region. This creates uniform stability across the whole shoe while maintaining manufacturing simplicity through the single-step molding process.
4Strength
If additional binders are used to enhance the connection between outsole and upper, then the strength of connection is improved, but the environmental harm increases due to hazardous substances
Solution Approach 1:
The textile two-dimensional region provides its own bonding capability through its structural features (loops, pores, or textured surfaces) that enable direct mechanical interlocking with the rubber material. This self-service bonding eliminates the need for external binders and hazardous substances, resolving the contradiction between connection strength and environmental harm.
