Disposable Urine Control Device Sealing Bead Conduit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional female urination devices are not easily portable and often lead to cleanliness issues due to the need for cleaning or rinsing, and they can spread urine inadvertently, especially in public or unsanitary conditions.
Innovation Solution
A disposable urine control device with a flexible, absorbent panel and sealing beads that can be folded compactly for easy carrying, featuring a conduit to direct urine into a receptacle, ensuring containment and absorption or directed flow without contaminating the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reusable urination devices are used, then functionality is provided, but cleanliness and hygiene deteriorate due to cleaning requirements and odor buildup
Solution Approach 1:
The patent applies the disposable principle by designing a single-use urination device that is discarded after one use. The device includes a absorbent layer, liquid-impermeable layer, and partition structure that can be manufactured cheaply and thrown away after use, eliminating cleaning requirements and ensuring hygiene without the complexity of reusable device maintenance
2Ease of operation
If conventional public toilet facilities are used, then urination function is provided, but hygiene deteriorates due to bacterial contamination and unclean conditions
Solution Approach 1:
The patent applies the intermediary principle by introducing a personal urination device that acts as a mediator between the user and the public toilet environment. The device includes a absorbent layer and liquid-impermeable layer that contain urine and prevent contact with contaminated surfaces, while the partition structure directs urine flow into the toilet bowl, thus maintaining hygiene while preserving urination convenience
3Ease of operation
If manual holding devices are used, then urination control is achieved, but portability deteriorates due to size and handling requirements
Solution Approach 1:
The patent applies the flexible shells and thin films principle by constructing the urination device with flexible materials including a absorbent layer and liquid-impermeable layer. This allows the device to be compact, lightweight, and easy to carry while maintaining the structural integrity needed for urination control. The flexible nature enables easy manipulation and positioning during use
4Reliability
If disposable devices are used, then hygiene is improved, but environmental impact worsens due to waste generation
Solution Approach 1:
The patent applies the discarding and recovering principle by designing a disposable urination device that can be easily discarded after use, eliminating the need for cleaning and disposal of biological materials. The device is constructed from materials that can be manufactured efficiently and disposed of conveniently, with the partition structure and absorbent layer containing all urine for complete disposal in the toilet, thus maintaining hygiene while minimizing environmental impact through efficient waste management
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 device provides a clean and convenient urination solution by containing urine within the device, preventing spills and allowing for easy disposal, thus maintaining hygiene and ease of use in various settings.
Implementation Method 1
an elongated absorbent layer attached to a longer liquid-impermeable layer
Implementation Method 2
an elongated absorbent layer attached to a longer liquid-impermeable layer

AI summary
A disposable urine control device for females during urination when in a crouched position. The control device is provided preferably folded flat and preferably packaged in a stack, each including an elongated flexible folded panel formed of disposable material and having side margins preferably narrowing toward a central portion from enlarged end portions thereof. A perimeter sealing bead extends upwardly from, and substantially continuously around the panel perimeter to provide stiffness and sealing against the labia majora of a female to contain urine within the perimeter sealing bead during urination. A flexible elongated conduit is connected at one end thereof in alignment with a urine drainage aperture formed into a central portion of the panel. When the panel and conduit are unfolded for use from a substantially flat folded orientation of the panel and a folded orientation of the conduit, urine is directed through the conduit into a toilet bowl. An inner sealing bead and urine impermeable layers may also be provided.
