Multi-Material Glove for Joint Flexibility and Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gloves lack flexibility and adaptability to fit different hand sizes and provide adequate protection and comfort, especially during activities like sports.
Innovation Solution
The glove is designed with multiple covering portions made of varying materials, with flexible second material used for joint and surface-covering portions to ensure comfort and fit, while maintaining strength, and includes dividing portions for thumb and finger flexibility, allowing for one-size-fits-all functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional gloves are made with uniform material throughout, then manufacturing is simple, but flexibility and comfort at joint areas are insufficient
Solution Approach 1:
The glove applies different materials to different regions: a first material for tip-covering portions requiring durability, a second flexible material for joint-covering portions requiring bendability, and a third material for surface-covering portions. This local differentiation resolves the contradiction by providing flexibility at joints without compromising overall manufacturing feasibility through modular construction.
Solution Approach 2:
The glove is divided into multiple functional segments: tip-covering portions, joint-covering portions, and surface-covering portions, each with distinct material properties. This segmentation allows each region to be optimized independently for its specific function while maintaining overall structural integrity.
2Adaptability or versatility
If conventional gloves are made with single material, then material selection is simple, but adaptability to different hand sizes and activities is limited
Solution Approach 1:
The multi-material construction enables the glove to serve multiple functions simultaneously: protection at finger tips, flexibility at joints, and overall hand coverage. The modular design with connecting portions allows the glove to adapt to different hand sizes and activity requirements while maintaining a unified structure.
3Ease of operation
If conventional gloves use uniform material density, then material usage is consistent, but comfort and fit for different body parts are inadequate
Solution Approach 1:
Different materials are selected for different body parts based on their specific requirements: flexible material for joints requiring movement, durable material for tips requiring protection, and appropriate materials for surface areas. This local optimization enhances comfort and fit while managing material variety through systematic selection.

AI summary
A glove comprises tip-covering portions, joint-covering portions, and surface-covering portions. Each of the tip-covering portions is made of a first material and configured to cover each palm or back side of tip portions of fingers. Each of the joint-covering portions is made of a second material, connected to corresponding one of the tip-covering portions, and configured to cover one of palm or back side of joint portions of the fingers. Each of the surface-covering portions is made of a third material, connected to at least one of the tip-covering portions and the joint-covering portions, and configured to cover surface portions other than hand portions covered by the tip-covering portions or the joint-covering portions. The second material is more flexible than the first or third material, so that the glove has one size and multi-size feature.
