Strape Glove Non-Elastic Web for Striking Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gloves do not provide a mechanical advantage or improve energy transfer when using striking tools like baseball bats or hammers, leading to reduced control, increased hand fatigue, and inefficient energy transfer.
Innovation Solution
A glove design featuring a non-elastic strap web between the thumb and fingers, with a contact friction loop that increases grip and leverage, distributing impact force more effectively and reducing muscle fatigue, while allowing for adjustable configurations to accommodate different hand and tool sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional gloves are used, then hand protection is provided, but mechanical advantage and energy transfer are not improved
Solution Approach 1:
The glove is segmented into distinct functional zones: a non-elastic strap web portion between thumb and fingers for energy transfer, elastic finger portions for flexibility, and a wrist strap for stabilization. This segmentation allows each zone to perform its specific function optimally without compromising the others.
Solution Approach 2:
The non-elastic strap web acts as an intermediary element between the hand muscles and the tool handle. It mediates the energy transfer by providing a stable, non-compliant interface that efficiently transmits muscular force to the tool while preventing energy absorption through material deformation.
2Force
If muscle strength is increased to improve control, then striking force improves, but hand fatigue increases
Solution Approach 1:
The wrist strap with elastic material acts as a counterbalancing element that supports the weight and instability of the tool handle. By providing this supporting counterforce, the wrist strap reduces the burden on hand muscles, allowing for sustained control without excessive fatigue.
Solution Approach 2:
The elastic finger portions and wrist strap provide automatic adaptation to tool handle dimensions and hand position. The elastic materials self-adjust to provide optimal support and control, reducing the need for continuous active muscle engagement and thereby reducing fatigue during prolonged use.
3Stability of the object's composition
If grip strength is increased to prevent slippage, then control improves, but energy absorption by hand muscles increases
Solution Approach 1:
The glove provides different material properties in different locations: non-elastic material where grip stability is needed (strap web), elastic material where flexibility is needed (fingers), and high-friction material where slip prevention is needed (handle contact surfaces). This local differentiation of material properties optimizes each function while minimizing energy loss.
Solution Approach 2:
The glove combines multiple materials with different properties: non-elastic strap web material for energy transfer efficiency, elastic finger material for adaptability, and high-friction coating material for grip enhancement. This composite construction allows the glove to simultaneously achieve grip stability and minimize energy absorption by distributing functions across different material zones.
4Speed
If tool head acceleration is increased, then impact force improves, but vibration shock increases
Solution Approach 1:
The elastic finger portions and wrist strap convert harmful vibration shocks into beneficial elastic deformation. By allowing controlled deformation of elastic materials, the glove absorbs and dissipates vibration energy that would otherwise be transmitted to the hand, while still permitting rapid tool head acceleration during the striking motion.
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 enhances control, striking force, and energy transfer, reduces hand fatigue, and dampens vibration shock, enabling more efficient use of striking tools with less physical effort and improved performance in sports and construction tasks.
Implementation Method 1
dampen the vibration shock associated with use of a striking tool during use. This is done by first distributing the shock wave through the length of the strap material and then dampening that wave within the strap material
Implementation Method 2
improved grip results from multiple factors including an increased surface contact area as well as increased friction when the strap is made with or used in combination with a tacky material or substance

AI summary
A glove made from narrow strap material. Glove advantages when used with a striking tool: improved control, improved striking force, improved tool head acceleration, improved energy transfer, reduced hand fatigue, improved grip, and reduced vibration shock. It can be configured for 1, 2, 3 or 4 fingers plus the thumb. The glove forms a web between the thumb and fingers. The width of the web and the tightness of fit on the thumb and fingers is controlled by a single pull-tab type of adjustment. The adjustment is secured by a contact friction loop which increases in friction during impact force use. The glove can be worn on a bare hand or over the top of a more conventional type of glove while still providing the same advantages.
