Solution Overview
Problem
Current methods for producing climbing footwear soles are inefficient, leading to long production times and high manufacturing costs due to waste and residual materials, making industrialization impossible.
Innovation Solution
A chemical composition comprising butyl rubber, carbon black, silica, dibenzothiazol-2yl disulphide, 3-triethoxysilylpropyl thiocyanate, aliphatic hydrocarbon resins, and fillers, used in a moulding process to create a single-piece climbing sole with specific design features for grip and flexibility, reducing material waste and production time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rubber strip cutting and folding methods are used, then climbing shoe soles can be manufactured, but production time becomes extremely long and industrialization becomes impossible
Solution Approach 1:
The patent replaces the traditional mechanical cutting and folding process with a chemical moulding process. The composition is introduced into a mould and vulcanized to directly form the complete sole structure, eliminating the need for mechanical cutting, folding, and stitching operations that characterized the prior art method
Solution Approach 2:
The patent merges multiple separate manufacturing operations (cutting, folding, stitching, assembly) into a single integrated moulding process. The composition contains all necessary components (rubber, fillers, reinforcement elements) that are combined in one vulcanization cycle to produce the complete sole
2Loss of substance
If traditional cutting and joining methods are used, then climbing shoe soles can be assembled, but material waste and residual materials increase significantly
Solution Approach 1:
The patent changes the fundamental parameter of material form from discrete strips requiring cutting to a mouldable composition that can be directly shaped. The composition includes fillers and reinforcement elements in specific proportions that enable direct moulding into the final sole geometry without material removal
Solution Approach 2:
The patent eliminates the need to discard excess material through cutting operations. The moulding process uses only the exact amount of composition needed to form the sole, with no residuals or waste materials generated from cutting, folding, or joining operations
3Ease of manufacture
If multiple rubber strips are cut and joined, then the sole structure can be formed, but manufacturing costs increase due to waste and complex processes
Solution Approach 1:
The patent replaces costly mechanical cutting, folding, and stitching operations with a single chemical vulcanization process in a mould. This substitution eliminates the need for multiple processing steps, specialized equipment, and skilled labor associated with traditional assembly methods
Solution Approach 2:
The patent combines multiple material components (rubber, fillers, reinforcement) and multiple manufacturing operations into a single integrated moulding process, thereby reducing the number of processing steps, equipment requirements, and associated manufacturing costs
4Extent of automation
If traditional assembly methods are used, then soles can be constructed, but the process becomes too complex for industrialization
Solution Approach 1:
The patent replaces complex mechanical assembly operations with a single chemical vulcanization process controlled in a mould. This substitution transforms a multi-step mechanical process requiring precise manual operations into a controllable chemical process suitable for automated industrial production
Solution Approach 2:
The patent changes the manufacturing approach from mechanical assembly of pre-cut components to chemical moulding of a formulated composition. This parameter change enables automation by replacing manual cutting and joining operations with a controllable vulcanization process that can be integrated into automated production lines
