Baseball Glove Web With Inclined Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baseball or softball gloves have a limited movable range of the web, which restricts the ease of closing the glove.
Innovation Solution
The design includes a web with a first protrusion and a second protrusion, each having through holes with inclined edges, allowing them to engage in a chain shape, expanding the movable range and facilitating easier opening and closing by changing the distance between the thumb and index finger parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the web structure uses conventional through holes without inclined edges, then the manufacturing is simpler, but the movable range of the web is limited
Solution Approach 1:
The patent modifies the geometric parameters of the through holes by adding inclined edges to at least one of the first or second through holes. This parameter change allows the web to achieve a larger movable range while maintaining ease of manufacture, as the inclined edge is a simple geometric modification rather than a complex structural addition.
2Ease of operation
If the thumb part and index finger part are brought closer together, then the ease of closing is improved, but stress is generated in the conventional web structure
Solution Approach 1:
The patent implements a dynamic web structure where the first and second protrusions can move relative to each other through the engaged through holes. The inclined edges enable smooth relative movement between the protrusions, allowing the web to dynamically adjust its configuration as the glove closes, reducing stress while maintaining ease of closing.
3Ease of operation
If the web has a larger movable range, then the ease of closing is improved, but the structure becomes more complex
Solution Approach 1:
The patent segments the web into two independently movable protrusions (first and second protrusions) that engage through the through holes. This segmentation allows each protrusion to move independently within its through hole, achieving a larger overall movable range while keeping the structural complexity manageable through the simple engagement mechanism of the through holes.

AI summary
The baseball or softball glove includes a thumb part, an index finger pan, and a web. The web includes a first protrusion and a second protrusion. The first protrusion has a first through hole. The second protrusion has a second through hole. At least either the first through hole or the second through hole has an inclined edge that extends obliquely upward from a base of the thumb part or the index finger part on a peripheral edge forming the through hole. The first protrusion and the second protrusion are engaged with each other in a state where the first through hole and the second through hole are connected to each other in a chain shape.
