Glove Impact-Resistant Pad Fixation via Coating Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labor gloves with impact-resistant pads tend to experience dislocation and detachment due to stretching, as the pads are not securely fixed to the stretchable fiber material, compromising their protective effectiveness.
Innovation Solution
A glove design featuring a stretchable fiber main body with a synthetic resin or rubber coating layer and sewn-on impact-resistant pads, which provides a space for improved impact absorption and prevents pad dislocation by inhibiting sewing thread movement during stretching, while the coating layer acts as a cushion to prevent tear and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the impact-resistant pad is adhered to the stretchable fiber material, then the fixation force is sufficient, but the pad may separate and dislocate as the glove main body stretches
Solution Approach 1:
The patent introduces a coating layer as an intermediary between the impact-resistant pad and the stretchable fiber material. This coating layer, made of synthetic resin or rubber, serves as a mediator that bonds the pad to the glove main body while accommodating stretching movements, preventing both detachment and dislocation during use
Solution Approach 2:
The patent creates a composite structure consisting of three layers: the stretchable fiber material (glove main body), the coating layer (synthetic resin or rubber), and the impact-resistant pad. This composite material system combines the advantages of each layer to achieve both strong fixation and position stability during stretching
2Reliability
If the impact-resistant pad is sewn onto the glove main body, then the pad remains fixed during stretching, but the sewing thread may move due to spaces between stitches and weave pattern
Solution Approach 1:
The coating layer acts as an intermediary that receives the sewing threads and distributes the fixation force across a broader area. This mediator prevents the sewing threads from moving through spaces in the weave pattern while maintaining strong fixation of the pad to the glove main body
3Strength
If the impact-resistant pad is directly adhered to the stretchable fiber, then the fixation is strong, but the coating layer may separate
Solution Approach 1:
The coating layer is applied to the glove main body in advance before the impact-resistant pad is attached. This preliminary coating creates a stable base layer that prevents separation of the coating from the stretchable fiber material during subsequent pad attachment and during glove use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glove achieves superior impact resistance and prevents dislocation and detachment of the impact-resistant pads, enhancing both protection and durability, with improved waterproofing and oil resistance due to the smooth interfaces between the pads and coating layers.
Implementation Method 1
when a large impact is applied onto the impact-resistant pad, the coating layer acts as a cushion material, whereby tear and the like of the glove main body is also prevented
Implementation Method 2
An internal face of the impact-resistant pad and an external face of the coating layer are preferably smooth. By virtue of the internal face of the impact-resistant pad and the external face of the coating layer each being smooth, an area is provided where these members are likely to be in close contact with each other with no gap therebetween, whereby water proofing properties and oil resistance can be improved
