Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional batting gloves provide inadequate shock absorption when hitting a high-speed ball, resulting in counterforces being directly received by the batter's fingers and palm, affecting performance.
Innovation Solution
A cushion pad with a ciliated member and a base member made of flexible plastic, featuring hollow protrusions and a rim belt with a pressure release valve and one-way valve, which is inflated using a pumping device to enhance shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional batting glove made of cloth or leather is used, then the glove provides basic grip and structure, but the shock absorption capability is insufficient
Solution Approach 1:
The patent applies pneumatic principles by incorporating air-filled hollow protrusions within the cushion pad structure. When a ball impacts the glove, the air inside these protrusions compresses and expands, providing effective shock absorption. This pneumatic mechanism significantly enhances the glove's ability to absorb impact forces compared to conventional solid or fabric-based gloves.
Solution Approach 2:
The cushion pad features a porous structure with numerous hollow protrusions that contain air. This porous architecture allows the material to deform and compress under impact, facilitating energy absorption through the compression and expansion of air pockets within the porous structure, thereby improving shock absorption while maintaining flexibility.
2Strength
If an air-filled cushion pad with multiple components is implemented, then superior shock absorption is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functional components into a single integrated cushion pad unit. The base member, ciliated member with hollow protrusions, and sealing rim are combined into one cohesive structure that can be manufactured as a single piece or pre-assembled unit. This integration simplifies the manufacturing process while maintaining the complex shock absorption functionality.
Solution Approach 2:
The cushion pad structure serves multiple functions simultaneously: the hollow protrusions provide shock absorption, the sealed rim enables air inflation and retention, and the overall design allows for easy attachment to batting gloves. This multi-functionality reduces the need for separate components, thereby simplifying manufacturing while achieving superior performance.
3Strength
If the cushion pad is inflated with air using a pumping device, then the shock absorption capability is significantly enhanced, but the device requires additional components and setup
Solution Approach 1:
The cushion pad is designed to be inflated with air before use through the sealed rim and valve mechanism. By performing the inflation action in advance, the cushion pad achieves its optimal shock absorption capability prior to encountering impact. This preliminary preparation ensures the air-filled structure is ready to effectively absorb shocks during actual use.
Solution Approach 2:
The shock absorption capability of the cushion pad is adjusted by changing the air pressure parameter within the hollow protrusions. By controlling the amount of air pumped into the cushion pad, users can optimize the shock absorption performance according to their specific needs, allowing for parameter adjustment without changing the physical structure.
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 cushion pad significantly improves shock absorption by distributing pressure through air-filled protrusions, providing superior protection and comfort during ball hits.
Implementation Method 1
a pumping device is plugged in the other opening. When air is pumped into a closed space among the ciliated member, the base member, and the rim belt by the pumping device
Implementation Method 2
The base member is attached to a back side of the ciliated member by high-frequency fusing their circumferences together

AI summary
The cushion pad according to the present invention contains a ciliated member and a base member, both made of a flexible plastic material and having a same planar shape. The ciliated member has a large number of hollow protrusions on a front side. The base member is attached to a back side of the ciliated member by high-frequency fusing their circumferences together to form a rim belt with two openings. A pressure release valve is plugged in one opening, and a one-way valve and a pumping device is plugged in the other opening. When air is pumped into a closed space among the ciliated member, the base member, and the rim belt by the pumping device, the cushion pad could offer significantly superior shock absorption.
