Segmented Loop Connection for Baseball Glove Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baseball or softball catching tools with leather members connected by a leather string become difficult to bend and follow hand movements, making it hard to perform ball-catching actions effectively.
Innovation Solution
The tool features a connection portion with a first loop contiguous to the first leather member and a second loop adjacent to the second leather member, with a string member passing through both loops along the central axis, allowing for easier bending and hand movement alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the outer peripheral portions of leather members are connected by a leather string winding around these portions, then the connection strength is improved, but the flexibility and ease of bending deteriorate
Solution Approach 1:
The connection portion is divided into multiple loops (first loop, second loop, third loop) arranged along the central axis, with string members passing through them sequentially. This segmentation allows the connection to maintain strength through multiple attachment points while enabling flexibility through the distributed loop structure that can deform independently during bending.
Solution Approach 2:
The loops are designed to be deformable and adaptable during bending operations. When the glove bends, the loops can change shape and relative position dynamically, allowing the connection to maintain integrity while accommodating the flexing motion. The string members passing through multiple loops create a dynamic connection that adjusts to bending stresses.
2Stability of the object's composition
If the leather members are rigidly connected to maintain structural stability, then the structural stability is improved, but the ability to follow hand movements deteriorates
Solution Approach 1:
The connection is segmented into multiple loops distributed along the central axis rather than a single rigid connection. This segmentation allows different parts of the connection to move independently, maintaining overall structural stability while enabling the glove to adapt to complex hand movements and flexing patterns.
Solution Approach 2:
The loops are formed from flexible leather or synthetic material that can deform during hand movements. These flexible loop structures maintain connection integrity while allowing the glove to conform to the dynamic shapes of the hand during catching motions, throwing motions, and wrist flexion.

AI summary
A glove includes: a first leather member on a side of a ball catching plane; a second leather member disposed to face the first leather member; and a connection portion in which the first leather member and the second leather member are connected at a part of an outer peripheral portion of the ball catching plane. The connection portion includes a first loop contiguous to the first leather member and having a central axis, a second loop disposed adjacent to the first loop in a direction along the central axis and contiguous to the second leather member, and a string member passing through the first loop and the second loop along the central axis. At least one identical string member passes through the first loop and the second loop.
