Protective Cup Fit Stability via Elastic Leg Strap Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jockstraps often exhibit poor fit and discomfort during intense movements due to play between the protective cup and the user's body, and their complex designs make them expensive to manufacture.
Innovation Solution
A protective device featuring a protective cup with a waist strap and a leg strap device that engages with the cup at both lower and upper points, using adjustable and elastic components to ensure a secure fit without complex construction, comprising a protective cup with a triangular shape, elastic or inelastic waist strap, and leg strap parts that run around the legs to maintain the cup's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional jockstrap designs are used with simple straps, then manufacturing cost is reduced, but fit and stability during intensive movements deteriorates due to play between the cup and body
Solution Approach 1:
The protective device is divided into multiple functional components: a protective cup with engagement means, a waist strap with adjustment mechanism, and leg straps with engagement means. This segmentation allows each component to be optimized independently for both manufacturing simplicity and functional effectiveness, resolving the contradiction between ease of manufacture and fit stability.
Solution Approach 2:
The leg straps are designed to be adjustable in length and tension, allowing the device to adapt dynamically to different body positions and movement intensities. This dynamic adjustment capability maintains reliable fit during intensive movements while keeping the overall design simple and cost-effective to manufacture.
2Reliability
If complex jockstrap designs are used to improve fit, then fit and comfort during intensive movements is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The engagement means are designed with universal functionality, serving multiple purposes: securing the leg straps to the protective cup, allowing adjustment of strap tension, and enabling easy donning and doffing of the device. This multi-functionality achieves high fit quality without requiring complex separate mechanisms for each function.
Solution Approach 2:
The adjustment mechanisms are designed to be user-operable without requiring additional tools or complex procedures. The user can independently adjust the waist strap and leg straps to achieve optimal fit, eliminating the need for complex pre-adjustment mechanisms or professional fitting procedures.
3Device complexity
If fixed-length straps are used, then device complexity is reduced, but adaptability to different body positions and movement intensities deteriorates
Solution Approach 1:
The leg straps incorporate adjustable length mechanisms that allow users to modify strap length according to different body positions and movement requirements. This dynamic adaptability is achieved through simple adjustment features rather than complex mechanisms, maintaining low device complexity while significantly improving versatility.
Solution Approach 2:
The strap system allows users to change key parameters such as strap length and tension to adapt to different body positions and movement intensities. These parameter changes are achieved through straightforward adjustment mechanisms, providing high adaptability without increasing overall device complexity.

AI summary
Protective equipment for protection of a user's lower abdominals includes a protective cup with upper and lower parts, a waist strap arranged to engage with and retain the protective cup on the user's body in a position where the protective cup hangs down with its lower part downwards and covers the user's genital body parts, a leg strap device, arranged to engage with and retain the protective cup in a position close to the user's body, the leg strap device including two leg strap parts, arranged to run around each leg of the user. The leg strap device engages with and runs from at least one lower engagement means in the protective cup's lower part, and backwards between the user's legs. The leg strap parts run up to and engage with the protective cup at at least one upper engagement means in the protective cup's upper part.
