Tennis Bra Pocket System with Elastic Slit Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bra systems fail to provide a safe, convenient, and economical method for receiving and supporting tennis balls while offering breast support and shape to the wearer.
Innovation Solution
A tennis pocket bra system comprising a strap assembly, a bra with laterally coupled front and rear sections, and patches with a linear slit and elastic band, allowing tennis balls to be removably received and retained, using stretchable fabric knitted from 95% nylon and 5% spandex, which provides support and shape to the breasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tennis balls are received in the bra system, then convenience and safety are improved, but device complexity increases
Solution Approach 1:
The bra system is divided into distinct functional components: pockets for ball reception, elastic bands for retention, and slits for ball insertion/removal. This segmentation allows each component to perform its specific function independently, improving ease of operation while managing complexity through modular design
Solution Approach 2:
The elastic bands automatically retain tennis balls in the pockets without requiring additional fastening mechanisms. The balls are retained through the natural elastic tension of the bands, and removal is facilitated by the slit opening, allowing the system to serve itself without complex controls or manual intervention
2Reliability
If elastic bands are used to retain tennis balls, then reliability of ball retention is improved, but ease of operation for ball removal deteriorates
Solution Approach 1:
The elastic bands are designed to be dynamic rather than static, allowing them to stretch and contract. The bands maintain strong retention force when at rest, but can be easily stretched to release balls. The slits provide a controlled opening mechanism that temporarily reduces retention force for ball removal while maintaining reliability during play
Solution Approach 2:
The elastic bands change their physical parameters (tension, stretch) based on the state of ball retention. When balls need to be removed, the bands are stretched beyond their normal tension, changing their retention parameter from high to low, facilitating easy removal while maintaining strong retention during normal use
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 system effectively and economically supports the breasts of the wearer while allowing for easy and safe retention and removal of tennis balls, enhancing user convenience and durability.
Implementation Method 1
An elastic band is provided within each patch. The elastic band surrounds the slit. The elastic band is adapted to return the slit to a closed orientation.

AI summary
A strap assembly includes an upper strap and left and right straps. The straps are coupled with respect to each other. A bra had front and rear sections depending from the straps. The bra has spaced arm holes and an upper neck hole and a lower body hole. At least one patch is operatively associated with the bra. The patch has upper and lower edges separated by a height. The patch has parallel left and right edges separated by a width. The patch has a periphery with stitching coupling the left and right and lower edges of the patch to the bra. A linear slit is formed in the patch parallel with, and closely spaced from, the upper edge of the patch.
