Glove Finger Shell Segmentation for Waterproof Tactility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional waterproof gloves suffer from water entry through sewn edges, reduced thermal insulation, high manufacturing costs, limited finger flexibility, and compromised tactility due to the use of flat waterproof linings and complex seam contours, making them unsuitable for activities like climbing and skiing.
Innovation Solution
A glove design featuring an outer shell composed of multiple finger shells with three lobes or tongues that are joined together at their edges, eliminating the need for a flat waterproof lining, and using waterproof strips to seal the edges, which simplifies manufacturing and enhances flexibility and tactility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat waterproof lining is used to ensure waterproof assembly, then waterproofing is achieved, but finger tactility and flexibility are reduced
Solution Approach 1:
The finger shell is divided into three separate lobes (first lobe, second lobe, third lobe) that can be independently formed and assembled. This segmentation allows each lobe to be optimized for both waterproofing and tactility, with the ability to create seamless joints between lobes that maintain finger sensitivity while ensuring waterproof integrity.
Solution Approach 2:
The invention transitions from a traditional flat two-dimensional lining to a three-dimensional multi-lobe structure. By forming the finger shell with multiple lobes that extend in different spatial dimensions, the design achieves waterproofing without compromising the natural contours and sensitivity of the finger tip area.

AI summary
The invention is directed to a glove that includes an outer shell having several finger shells. At least one finger shell includes first, second, and third tongues, the first tongue forming the palm portion of the finger shell, and the second and third tongues forming the back and side portions of the finger shell. The tongues are joined together at their adjacent edges. The glove can further include waterproof strips overlapping the adjacent edges and fastened to the edges. The invention is also directed to a method of manufacturing the glove.
