Urine Absorption Pad With Self-Standing Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urine absorption pads for men are ineffective in capturing the entire voided volume of 150 cc to 200 cc due to design limitations, such as urine release direction and the presence of the scrotum obstructing absorption, leading to incomplete absorption and leakage.
Innovation Solution
A urine absorption pad design featuring self-standing guides A and B that rise to control urine flow, with guide A having higher water retainability and guide B facilitating urine distribution across the pad, preventing overflow and ensuring complete absorption by utilizing porous, water-permeable materials without superabsorbent polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional pad design is used for men, then the pad is compact and easy to wear, but it cannot capture the entire voided volume of 150 cc to 200 cc due to the scrotum obstructing urine flow
Solution Approach 1:
The pad is divided into multiple functional zones: a front portion positioned in front of the scrotum to receive urine flow, and a rear portion behind the scrotum to absorb urine that flows past. This segmentation allows the pad to capture urine from multiple directions and positions, overcoming the obstruction caused by the scrotum and reliably capturing the entire voided volume of 150-200 cc.
Solution Approach 2:
The front portion of the pad acts as an intermediary structure positioned between the urethral opening and the rear absorbent portion. It receives urine flow directly from the urethra and guides it toward the rear portion, ensuring that urine is captured even when the scrotum obstructs direct flow to the rear absorbent material.
2Ease of operation
If the scrotum is present immediately below the urethral opening, then it is a natural anatomical feature, but it becomes an obstacle that prevents urine from reaching the absorbent in the rear side of the pad
Solution Approach 1:
The absorbent material is segmented into a front portion and a rear portion, with the front portion positioned to receive urine flow before it encounters the scrotum. This segmentation ensures that urine is absorbed in the region where it naturally flows, rather than requiring it to overcome the scrotal obstruction to reach the rear absorbent.
Solution Approach 2:
The pad provides different functional qualities at different locations: the front portion has high absorbency to capture urine flow directly from the urethra, while the rear portion provides additional absorption capacity for urine that flows past the scrotum. This local differentiation of absorbent properties optimizes urine capture throughout the entire voiding process.
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 pad effectively captures 150 cc to 200 cc of urine without leakage, allowing for reliable use during daily activities and reducing the need for frequent urination interruptions, enhancing usability and quality of life for men with frequent urination issues.
Implementation Method 1
The guides A and B are separate bodies, are porous bodies that are continuous voids and have water permeability
Implementation Method 2
guide A which is self-standing so as to rise and has a certain height... allows urine to permeate
Implementation Method 3
guide A... has higher water retainability than guide B... prevents overflow of urine to the outside of the system
Implementation Method 4
an absorbent that is sandwiched between the front surface sheet and the back surface sheet and absorbs urine
Implementation Method 5
the absorbent... absorbs urine having passed through the front surface sheet

AI summary
A urine absorption pad for preventing leakage of urine is provided. A urine absorption pad includes: a front surface sheet (16) which has water permeability and contacts a skin; a back surface sheet (17) which has water impermeability and contacts underwear; an absorbent (18) which is sandwiched between the front surface sheet (16) and the back surface sheet (17) and absorbs urine having passed through the front surface sheet (16); and a guide A (11) and a guide B (12) which allow urine to permeate and are self-standing so as to rise to the front surface sheet (16) side with respect to the absorbent (18) to control flow of urine. The guide A (11) is arranged at an edge portion, and the guide B (12) is arranged so as to extend in a left-right direction.
