Detachable Chest Protector Segmentation for Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chest protectors integrated into waistcoat-type garments cannot be easily opened to cool down the wearer while maintaining protection, as they cover the chest and upper abdominal region.
Innovation Solution
A detachable chest protector with left and right members that engage with each other, allowing for separation to facilitate cooling while maintaining protection, featuring protruded portions and receptors to manage pressing forces and ensure rigidity and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single piece front shell covers the chest and upper abdominal region, then protection performance is improved, but the ability to open the front portion for cooling is worsened
Solution Approach 1:
The chest protector is divided into left and right members that can be separated. Each member has engaging portions that connect them when closed, but can be released to allow the front portion to open for cooling while maintaining protection coverage.
2Ease of operation
If the chest protector is made separable with left and right members, then the ability to open for cooling is improved, but the strength to resist pressing force is worsened
Solution Approach 1:
Stopping portions are pre-provided in the engaging portions of the left and right members. When pressing force is applied from the front, these stopping portions engage to resist the force, preventing premature separation while allowing intentional separation when needed for cooling.
3Stability of the object's composition
If multiple protruded portions are used for engagement, then stress distribution is improved, but device complexity is worsened
Solution Approach 1:
The engagement structure is segmented into multiple protruded portions distributed across the left and right members. This segmentation allows stress to be distributed across multiple contact points rather than concentrated at a single point, improving stability while keeping each individual protruded portion simple in design.

AI summary
[Problem] The invention aims to enabling a front portion of eight element and chest protector to be easily undone to allow cooling down while maintaining protection performance for a chest protector fitted to a garment. [Resolving Means] A chest protector (3) detachably fitted to the back surface of a body garment comprises left and right shells (36L) and (36R), with the left and right shells (36L) and (36R) engaging in a separable manner.
