Shoe Upper Composite with Point-Like Laminated Ventilation Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breathable shoes and clothing do not provide sufficient breathability, especially during heavy sweating, as they lack efficient sweat removal and moisture evaporation mechanisms.
Innovation Solution
The shoe and clothing incorporate a composite material where a ventilation layer is laminated to a waterproof, water-vapor-permeable membrane in a point-like or net-like manner, enhancing sweat removal and moisture evaporation through the membrane and ventilation layer interface, allowing for improved air circulation and evaporation during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ventilation layer is placed inside the shoe with spacers to keep it at a distance from the outer layer, then breathability is improved, but the structure becomes more complex and the sweat removal efficiency is insufficient for heavy sweating
Solution Approach 1:
The invention extracts the ventilation function from a separate internal layer structure and integrates it directly into the outer layer through a perforated or mesh-like design. This eliminates the need for spacers and separate ventilation layers, simplifying the overall structure while maintaining breathability functionality.
Solution Approach 2:
The invention merges the outer layer and ventilation layer into a single integrated structure where the outer layer itself possesses ventilation properties through perforations or mesh patterns. This combination eliminates the need for separate layers and spacers, reducing structural complexity while improving sweat removal efficiency.
2Object-affected harmful factors
If a waterproof membrane is used to protect from external moisture, then water protection is improved, but sweat vapor escape is hindered
Solution Approach 1:
The invention applies different properties to different parts of the shoe upper: the waterproof membrane provides water protection in areas exposed to external moisture, while the perforated or mesh ventilation areas allow sweat vapor to escape. This local differentiation of material properties resolves the contradiction between water protection and vapor permeability.
Solution Approach 2:
The invention uses a composite structure combining a waterproof membrane with a perforated or mesh ventilation layer. The membrane provides water protection while the perforated sections allow vapor transmission, creating a material system that simultaneously achieves both water protection and sweat vapor escape functionality.
3Productivity
If the ventilation layer is laminated to the membrane in a point-like or net-like manner, then sweat removal and evaporation are significantly improved, but the manufacturing process becomes more complex
Solution Approach 1:
The lamination process is segmented into discrete point-like or net-like bonding areas rather than continuous bonding. This segmentation allows sweat and vapor to pass through the unbonded areas while maintaining structural integrity at the bonded points, improving sweat removal efficiency without requiring completely new manufacturing technologies.
Solution Approach 2:
The ventilation layer uses a porous or perforated structure that, when laminated in a net-like pattern to the membrane, creates channels and pathways for sweat and vapor to pass through. The porous structure enables efficient moisture removal while the net-like lamination pattern balances structural support with vapor transmission.
