Waterproof Glove with Breathable Sections and Coating Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gloves for cycling and outdoor sports face challenges in maintaining hand warmth and breathability in cold, wet conditions, as existing solutions often result in heat loss due to moisture retention and lack of windproofing.
Innovation Solution
A waterproof and breathable glove assembly is created by coating an outer shell with a waterproof material, including masked sections for breathability, and securing an inner liner, with optional textured coatings for grip and insulation, utilizing materials like Gore-Tex and OutDry technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer shell is coated with waterproof material on the entire inner surface, then waterproofing is improved, but breathability deteriorates
Solution Approach 1:
The patent applies local quality by creating breathable sections with cut-out patterns on specific areas of the inner surface of the outer shell, while maintaining waterproof coating on other areas. This allows different regions of the glove to have different properties: waterproof in most areas and breathable in specific sections, resolving the contradiction between overall waterproofing and localized breathability.
Solution Approach 2:
The inner surface of the outer shell is segmented into coated and uncoated regions through the cut-out pattern design. The waterproof coating is applied selectively to certain areas while leaving other areas exposed, creating a segmented structure that provides both waterproofing and breathability functions in different zones of the glove.
2Object-generated harmful factors
If breathable sections are created in the outer shell, then moisture vapor transfer is improved, but waterproofing deteriorates
Solution Approach 1:
The breathable sections are created as localized cut-out patterns on the inner surface, allowing moisture vapor to escape from specific areas while the rest of the surface maintains its waterproof coating. This local breathability approach preserves overall waterproofing while enabling targeted moisture vapor transfer.
Solution Approach 2:
The inner liner acts as an intermediary layer between the breathable sections of the outer shell and the user's hand. It manages moisture transport while maintaining the waterproof barrier, allowing the system to achieve both breathability and waterproofing through the interaction of multiple layers with different properties.
3Object-affected harmful factors
If the entire inner surface is coated with waterproof material, then windproofing is improved, but heat loss due to moisture retention worsens
Solution Approach 1:
By creating localized breathable sections rather than uniform coating, the patent allows heat and moisture to escape from specific areas while maintaining windproofing in other areas. This resolves the contradiction by providing targeted ventilation to prevent heat loss while preserving overall wind protection.
Solution Approach 2:
The patent converts the potential harm of moisture retention (which causes heat loss) into a benefit by designing breathable sections that actively manage moisture escape. The cut-out patterns in the waterproof coating create controlled pathways for moisture vapor to escape, turning what would be a harmful accumulation into a beneficial ventilation mechanism.
4Object-generated harmful factors
If breathable sections are added to the glove design, then moisture management is improved, but device complexity worsens
Solution Approach 1:
The breathable sections are integrated into the outer shell through cut-out patterns in the waterproof coating, rather than adding separate components. This segmentation approach maintains moisture management functionality while minimizing structural complexity by using a single-layer solution with patterned coating rather than multiple separate layers or components.
