Functional Diaper With Segmented Excrement Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diapers fail to effectively separate and store urine and excrement, leading to hygiene issues and pressure sores due to the close proximity of excrement to the skin, and existing solutions are inconvenient and expensive.
Innovation Solution
A functional diaper with a dual excrement storage structure featuring an upper and lower compartment connected by a passage with waterproof zippers, where excrement is collected through an excrement outlet, preventing skin contact and utilizing a silicone-based adhesive band with antimicrobial properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional diapers are used to contain waste, then the diaper structure is simple and easy to manufacture, but the hygiene is poor because the space between the diaper and human body is very narrow causing excrement to touch the skin
Solution Approach 1:
The diaper is divided into functionally separate zones: an absorption layer for urine, a reflection layer for thermal management, and a through-hole layer with large openings for excrement passage. This segmentation allows each layer to specialize in its function, improving hygiene by preventing excrement contact with skin while maintaining structural feasibility
Solution Approach 2:
The through-hole layer introduces a dimensional change by creating large vertical openings (5-10mm diameter) that extend through the diaper structure, providing a three-dimensional excrement passage space. This allows excrement to pass through without contacting the absorption layer or skin, solving the hygiene problem without requiring complex mechanical components
2Object-affected harmful factors
If the space between diaper and human body is made narrow for fit, then the diaper fits well, but excrement infiltration risk increases especially for women where anus is close to vagina
Solution Approach 1:
The through-hole layer acts as an intermediary structure between the skin and excrement, providing a dedicated passage way that directs excrement flow away from sensitive areas. The reflection layer further mediates by creating a thermal barrier that prevents moisture accumulation, reducing the risk of excrement infiltration while maintaining close fit
Solution Approach 2:
The diaper utilizes flexible thin film structures for the through-hole layer and reflection layer that can conform to body contours, maintaining good fit while providing the necessary functional separation. The flexible nature allows the diaper to adapt to body movements without compromising the excrement passage function
3Object-affected harmful factors
If a functional diaper with excrement storage part and passage is implemented, then hygiene and smell prevention are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The diaper is manufactured as segmented layers (absorption layer, through-hole layer, reflection layer) that can be produced separately and then assembled through lamination. This segmentation simplifies manufacturing by allowing each layer to be optimized and produced using standard processes, then combined to create the functional excrement passage system
Solution Approach 2:
The diaper employs composite material construction where different material layers are combined to achieve multiple functions: superabsorbent polymers for urine absorption, porous materials for the through-hole structure, and reflective materials for thermal management. These composite structures can be manufactured using existing lamination and coating technologies, reducing overall manufacturing complexity

AI summary
The present invention relates to a functional diaper, which can be worn by a baby or a patient and comprises a body having, therein, an excrement storage part, which is a space for gathering excrement, wherein the upper part of the excrement storage part has an excrement entrance that allows excrement to enter therein and exit therefrom. The present invention allows urine or excrement to be immediately and separably stored in a separate space of the diaper immediately after coming out of the anus such that there is little odor and excrement does not come in contact with the skin, and thus the present invention prevents bedsores and the like and is remarkably clean and sanitary.
