Motorcycle Glove Stitching Extraction and Impact Shield Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle riding gloves lack effective protection against injuries from falls and accidents, particularly at the finger tips and wrist, due to inadequate stitching and conventional materials prone to abrasive damage, and fail to prevent fractures and sprains.
Innovation Solution
A glove structure with reduced and protected stitching, integrated rigid polyurethane protection for the upper fingers, a shield for the back of the hand, and a wrist joint protector to manage forces during accidents, using non-rigid and rigid polyurethane layers with internal stitching and Velcro fixation, ensuring comprehensive impact and sliding abrasion protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stitching is used in glove manufacturing, then the glove can be made with standard construction methods, but the stitches are prone to abrasive damage from road surface friction causing the glove to open at finger tips
Solution Approach 1:
The patent removes stitches from the outer surface of the glove by inserting them internally between the first and second leather elements. This extraction of stitches from the external environment eliminates their exposure to abrasive road surface friction, preventing the stitching failure that occurs in conventional gloves.
Solution Approach 2:
The patent uses a continuous leather element that wraps around the finger, creating a seamless protective shell that encloses the internal stitching. This flexible leather shell protects the stitches from external abrasion while maintaining the flexibility needed for hand movement.
2Object-affected harmful factors
If plastic moulded parts are applied to protect the upper part of fingers and hand, then sliding protection on ground or road surface is achieved, but protection against fractures and sprains is insufficient
Solution Approach 1:
The patent combines multiple materials with different properties: leather elements for flexibility and abrasion resistance, rigid plastic moulded parts for impact protection, and internal stitching for structural integrity. This composite construction provides both sliding protection and strength against fractures and sprains that neither material could achieve alone.
Solution Approach 2:
The protective glove structure is divided into multiple functional segments: first and second leather elements for the base structure, plastic moulded parts for rigid protection at critical areas, and internal stitching for reinforcement. Each segment performs a specific protective function, creating comprehensive protection against different types of injuries.
3Strength
If rigid protective devices are applied to the upper part of the glove, then protection against sliding and impact is improved, but the glove structure becomes less flexible and comfortable
Solution Approach 1:
The patent applies rigid plastic moulded parts only at specific locations where impact protection is most needed (upper part of fingers and hand), while the rest of the glove maintains flexible leather construction. This localized application of rigidity provides necessary protection without compromising overall hand flexibility and comfort.
Solution Approach 2:
The glove structure allows the rigid plastic moulded parts to move and flex with the natural movement of the hand and fingers. The plastic components are designed to accommodate dynamic hand movements during riding, maintaining protection while preserving ease of operation and comfort.

AI summary
A motorcycle glove structure comprises a system for protecting the fingers, made with a double layer of plastic, the first layer of which is injected directly and coextensively onto a flat part made of leather or similar material or fabric. The second layer made of impact and abrasion resistant plastic is injection-molded over the first layer and preferably has projections opposite the minor knuckles. The structure also comprises a shield which is made of impact and abrasion resistant plastic applied to the back of the hand and which has at the front portions shaped so as to mate with projections formed at the end of said second layer for protecting the fingers, said co-operating projections being positioned opposite the major knuckles of the hand.
