Solution Overview
Problem
Existing urine collection devices are complex, costly, and prone to accidental urine leakage during night sleep due to the complexity of pump and valve systems, particularly in urostomy pouches.
Innovation Solution
A urine collection device comprising a urostomy pouch, a urine collection bottle, and a flexible tube, where the bottle is designed with a corrugated wall to create negative pressure, ensuring safe and reliable urine transfer to the bottle without leakage, using a manually-rotatable valve and threaded connectors for sealed fluid communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional pump systems and complex valve systems are used in urine collection devices, then urine drainage reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent removes the complex pump and valve systems from the urine collection device, retaining only the essential valve for manual control. This extraction of unnecessary components directly reduces device complexity while maintaining the core urine collection function through the bottle's positioning and simple valve mechanism.
Solution Approach 2:
The urine collection bottle is designed to utilize the user's own body movements and positioning to facilitate urine flow. The bottle's weight and position create the necessary pressure differential, eliminating the need for external pump systems. The system serves itself by using gravity and user positioning rather than mechanical assistance.
2Reliability
If additional pump systems and complex valve systems are used in urine collection devices, then urine drainage reliability is improved, but exploitation expenditures increase
Solution Approach 1:
By removing pump systems and complex valve mechanisms, the patent significantly reduces manufacturing costs and exploitation expenditures. Only simple, inexpensive components remain: a bottle, a flexible tube, and a basic valve, all of which can be manufactured at low cost and are easy to replace if needed.
Solution Approach 2:
The patent employs inexpensive, easily replaceable components that can be manufactured cheaply. The simple valve, flexible tube, and bottle design allow for low-cost production and potential disposable use, reducing exploitation expenditures while maintaining functional reliability.
3Device complexity
If a simple urostomy pouch system is used during night sleep, then device complexity is reduced, but accidental urine leakage occurs due to pouch squeezing
Solution Approach 1:
The flexible tube acts as an intermediary element between the urostomy pouch and the collection bottle. It transmits the pressure differential created by the bottle's weight and position to the pouch, ensuring urine flow while preventing backflow and leakage even when the pouch is squeezed during sleep.
Solution Approach 2:
The patent utilizes hydraulic pressure principles by positioning the collection bottle below the pouch level, creating a pressure differential that drives urine flow from pouch to bottle. This passive hydraulic system prevents leakage by maintaining negative pressure in the pouch, eliminating the need for active pumps or complex valves.
4Stress or pressure
If the urine collection bottle is made squeezable with corrugated wall, then negative pressure creation is improved, but bottle structural complexity increases
Solution Approach 1:
The corrugated wall design introduces curved, flexible surfaces to the bottle structure. These curved ridges and grooves allow the bottle to be squeezed and deformable, creating negative pressure when compressed. The curvature enables the structural complexity to achieve the desired pressure control function.
Solution Approach 2:
The bottle incorporates a flexible corrugated wall structure that can deform under compression. This flexible shell design allows the bottle to be manually squeezed to create negative pressure for urine evacuation, then return to its original shape, providing a simple mechanical means of pressure control without complex mechanisms.

Function Achieved in This Case
The device prevents accidental urine leakage by maintaining negative pressure within the system, ensuring safe and reliable urine collection during sleep, reducing complexity and cost by eliminating the need for additional pump systems.
Implementation Method 1
The essence of the invention is the urine collection bottle of a special configuration allowing to create a negative pressure or such rarefaction in the urine collection device, that the discharged urine in the urostomy pouch can be safely transported to the urine collection bottle
Implementation Method 2
The corrugated wall is formed such that it can return the urine collection bottle to its initial volume or state when the pressure between the urine collection device and the surrounding environment is equalized

AI summary
The present invention relates to a urine collection device that comprises a urostomy pouch (1), a flexible tube (5) and a urine collection bottle (6). The urine collection bottle comprises a corrugated wall (9) allowing to squeeze the urine collection bottle decreasing its volume. The corrugated wall is formed so that it can return the urine collection bottle to its initial volume or state when the pressure between the urine collection device and the surrounding environment is equalized. The present invention is also a method of use of the urine collection device wherein before a use the urine collection bottle is squeezed by means of the corrugated wall of the urine collection bottle. The squeezed urine collection bottle is connected to the urostomy pouch via the flexible tube creating fluidly connected and from environment sealed system.
