Protective Garment Crotch Structure for Leak-Proof Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective garments for leakage protection, such as sanitary panties, lack an improved user experience in terms of aesthetic appearance and comfort while maintaining absorption and protection against leakage, and there is a need for a washable garment that can be reused.
Innovation Solution
A protective garment with a crotch part comprising a first distribution layer with large pores, a second distribution layer with small pores, a liquid-absorbing layer, and a liquid barrier, featuring a dorsal and ventral shaping element that enhances fit and leakage protection, and a connection pattern covering at least 50% of the first distribution layer at the genitalia area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a washable protective garment is designed with multiple layers and connections for leakage protection, then absorption and protection against leakage are improved, but device complexity increases
Solution Approach 1:
The crotch part is divided into multiple functional layers: a first distribution layer with large pores for initial liquid distribution, a second distribution layer with small pores for refined distribution, a liquid-absorbing layer for absorption, and a liquid barrier for prevention. This segmentation allows each layer to perform its specific function efficiently while maintaining overall system reliability.
Solution Approach 2:
The connection pattern is strategically distributed across the first distribution layer, with higher density in the genitalia area (covering at least 50% of this region) and lower density in other areas. This local variation optimizes the balance between leakage protection and garment flexibility, addressing the technical contradiction by concentrating structural elements where they are most needed.
2Reliability
If a protective garment uses elastic elements extending past the crotch part to achieve sealing, then leakage protection is improved, but comfort and aesthetic appearance deteriorate
Solution Approach 1:
The connection pattern is non-uniformly distributed, with higher connection density in the genitalia area (covering at least 50% of this region) and lower density in other areas. This local variation optimizes the balance between leakage protection and garment flexibility, addressing the technical contradiction by concentrating structural elements where they are most needed.
Solution Approach 2:
The first distribution layer is designed with relatively large pores to allow flexibility and comfort while the second distribution layer has relatively small pores for refined liquid distribution. This use of porous materials with varying pore sizes enables the garment to maintain comfort and aesthetic appearance while achieving effective sealing and leakage protection.

AI summary
Protective garment (100) in the form of a pantie, a pair of trousers or other legwear with or without an upper/torso part, comprising a front part (101); a back part (102); a waist (103); and a crotch part (110) having a leak-proof body (120). The invention is characterised in that the garment comprises a dorsal shaping element (130), arranged along the intergluteal cleft of a user, fastened to or constituting an integrated part of the leak-proof body and fastened to or constituting an integrated part of the back part, in that the dorsal shaping element (130) does not extend all the way up the waist, and in that the dorsal shaping element (130) is arranged so that, when a dorsal/upward force is applied thereto when the waist is pulled upwards, it in turn forces a part of the crotch part extend-ing along the intergluteal cleft of said user upwards.
