Urostomy Bag Absorbent Insert Gelatinizing Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urostomy appliances lack an absorbent gel insert with deodorizing agents, are cumbersome and heavy, and have leak-prone closures, making them difficult for individuals with mobility issues to use and interfering with clothing.
Innovation Solution
A urostomy bag with a water-permeable absorbent insert containing a gelatinizing agent and a resealable secondary aperture, designed to be compact, odor-resistant, and easy to attach and detach, featuring a gelatinizing agent that turns urine gelatinous to prevent leakage and a deodorizer to neutralize odors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing urostomy appliances are used without an absorbent gel insert, then the structure remains simple, but odor protection and leak prevention are insufficient
Solution Approach 1:
The absorbent insert with gelatinizing agent is nested inside the urostomy bag, creating a multi-layered system where the insert is placed within the bag's interior space. This nesting approach adds functional complexity for odor and leak protection while maintaining the overall compact structure of the appliance.
Solution Approach 2:
The invention combines multiple materials with different properties: the water-permeable outer layer for fluid passage, the absorbent core for moisture absorption, and the gelatinizing agent for gel formation. This composite material structure enhances odor and leak protection by leveraging the complementary properties of each material layer.
2Quantity of substance
If existing urostomy appliances are made large to accommodate waste, then storage capacity is sufficient, but the appliance becomes heavy and interferes with clothing
Solution Approach 1:
The gelatinizing agent changes the physical state of urine from liquid to gel, fundamentally altering the density and volume characteristics of the waste. This parameter change allows the same quantity of waste to occupy less space and weigh less, resolving the contradiction between storage capacity and appliance weight.
Solution Approach 2:
The urine undergoes a phase transition from liquid to gel state through the gelatinizing agent. This phase change increases the waste's volume efficiency and reduces its weight, enabling sufficient storage capacity while maintaining a lighter, more comfortable appliance that does not interfere with clothing.
3Ease of operation
If existing urostomy appliances require direct draining into a toilet, then no additional components are needed, but usability is difficult for people with mobility issues
Solution Approach 1:
The invention extracts the draining function from the mandatory action and replaces it with a removable absorbent insert. Users can simply remove the insert through the secondary aperture and dispose of it in a toilet or receptacle, eliminating the need for complex draining mechanisms while greatly improving ease of operation for mobility-impaired users.
Solution Approach 2:
The absorbent insert is designed to be self-contained and removable, allowing users to easily detach and dispose of waste without requiring assistance or complex maneuvers. The insert's ability to be independently removed through the secondary aperture enables self-service waste disposal, significantly improving usability for people with mobility issues.
4Ease of operation
If a secondary aperture is added for insert removal, then ease of operation improves, but leak risk increases
Solution Approach 1:
The gelatinizing agent acts in advance to convert urine to gel before the insert is removed. This preliminary action ensures that waste is already in a contained gel state, reducing leak risk during the insert removal process through the secondary aperture. The deodorizer is also pre-positioned to neutralize odors before they can escape.
Solution Approach 2:
The gelatinized waste acts as an intermediary between the liquid urine and the external environment during insert removal. This gel state serves as a protective mediator that prevents liquid leakage while allowing the insert to be easily detached through the secondary aperture, thus maintaining both ease of operation and leak resistance.
