Protective Grip Structure for Hand Protection Without Losing Dexterity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand protection solutions, such as gloves and grips, often fail to provide adequate protection against punctures and friction during activities like manual labor, gymnastics, and exercises, while maintaining dexterity and comfort.
Innovation Solution
A grip with a concave-shaped wrist end, a wrist strap secured at an anchor location, and a combination of elastic and non-elastic sections in the wrist strap, along with a multi-layer material comprising non-woven composite and synthetic rubber, providing enhanced protection and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gloves or grips are used to protect hands from punctures and friction, then protection is provided, but dexterity and comfort are compromised
Solution Approach 1:
The protective material is divided into multiple sections: a palm section with enhanced protection, finger sections with individual dexterity, and a wrist section with force distribution features. This segmentation allows each area to provide appropriate protection while maintaining natural hand movement and dexterity in all zones.
Solution Approach 2:
Different regions of the protective material have different properties - the palm section uses thicker, more abrasion-resistant material for maximum protection, while the finger sections use thinner, more flexible material to maintain dexterity. The wrist section incorporates a concave shape and force distribution features localized to that area.
2Strength
If thick protective material is used to enhance durability and protection, then resistance to abrasion and punctures improves, but flexibility and comfort deteriorate
Solution Approach 1:
The protective material exhibits local quality variations with different thicknesses and material densities in different areas. The palm section uses thicker, high-strength material for maximum protection against abrasion and punctures, while the finger sections use thinner, more flexible material that maintains natural finger movement and comfort.
Solution Approach 2:
The protective material combines multiple materials with different properties - high-strength abrasion-resistant materials in the palm area for durability, and more flexible materials in the finger areas for comfort and dexterity. This composite approach allows simultaneous achievement of protection and flexibility.
3Reliability
If a wrist strap is added to secure the grip, then stability and protection improve, but device complexity increases
Solution Approach 1:
The wrist strap is integrated with the protective material as a unified structure rather than being a separate component. The strap emerges from the concave-shaped wrist section of the protective material itself, combining the wrist protection and strap functions into a single integrated element, thereby providing stability without significantly increasing overall device complexity.
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 grip effectively distributes force on the wrist, maintains hand dexterity, and offers high durability and protection against abrasion, chemicals, and UV light, while being comfortable to wear.
Implementation Method 1
The wrist strap can include an elastic section and a non-elastic section

AI summary
Disclosed is a grip that includes a material having a wrist end, a finger end, and sides that extend from the wrist end to the finger end. The wrist end of the material has a concave shape that (i) is between the sides of the protective material and (ii) defines at least two legs on opposite sides of an apex of the concave shape. A thumb guard is defined on a first side of the sides of the material. A wrist strap is attached to a leg of the wrist end.
