Double-Walled Urine Collection Pouch with Valve for Leak Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal waste/specimen collection devices are difficult to adjust and install, uncomfortable for animals, prone to leakage, and not suitable for long-term use, leading to skin irritation and unsanitary conditions.
Innovation Solution
A double-walled pouch with a valve at the bottom and flexible adhesive straps for secure attachment, preventing leaks and easy removal, designed for both male and female animals, allowing for easy attachment, detachment, and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable collection bags are used, then ease of removal is improved, but reliability deteriorates due to leakage during animal movement
Solution Approach 1:
The collection device is divided into two separate components: a reusable harness and a disposable collection bag. This segmentation allows the harness to be adjusted and reused while the bag is easily removed and disposed of, resolving the contradiction between ease of removal and leak resistance during animal movement.
Solution Approach 2:
The collection bag is designed as a disposable component that is easily removed and discarded after use. This eliminates the need for cleaning and sanitization, ensuring reliable containment during animal movement while maintaining ease of removal through simple detachment from the harness.
2Ease of manufacture
If cloth apparatus is used, then ease of cleaning is improved, but reliability deteriorates due to saturation and skin irritation
Solution Approach 1:
The collection bag is designed as a disposable plastic component that replaces cloth apparatus. It provides reliable containment without saturation, eliminating skin irritation while maintaining ease of cleaning through simple removal and disposal rather than washing.
Solution Approach 2:
The collection bag is made from flexible plastic material that forms a waterproof barrier. This thin film structure provides reliable containment to prevent skin irritation while maintaining flexibility for comfortable animal wear and easy removal.
3Ease of operation
If flexible adhesive straps are used, then ease of attachment is improved, but device complexity deteriorates due to secure attachment requirements
Solution Approach 1:
The attachment mechanism replaces complex mechanical fastening systems with flexible adhesive straps. This substitution provides ease of attachment through simple sticking while maintaining secure attachment through the adhesive bond, reducing overall device complexity.
Solution Approach 2:
The flexible adhesive straps are made from flexible material that can conform to the animal's body contours. This flexibility allows easy attachment and adjustment while maintaining secure attachment through the adhesive property, simplifying the overall attachment mechanism.
4Ease of operation
If unsealed collection bags are used, then ease of installation is improved, but reliability deteriorates due to leakage during prolonged use
Solution Approach 1:
The collection device separates the harness (reusable) from the collection bag (disposable). The bag is designed with a valve mechanism that maintains seal integrity during animal movement while allowing easy installation and removal from the harness, resolving the contradiction between ease of installation and leak resistance.
Solution Approach 2:
The collection bag is designed as a disposable component with integrated sealing and valve mechanisms. It provides reliable leak resistance during prolonged use while maintaining ease of installation through simple attachment to the harness, eliminating the need for cleaning and reuse.
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 leak-resistant, comfortable, and easy-to-use solution for urine/specimen collection, reducing skin irritation and environmental damage, while allowing animals to move freely without leakage, facilitating timely disposal and potentially reducing marking behavior.
Implementation Method 1
The inner valve shaped bottom pouch fits into the outer cylinder shaped pouch. The seal between the layers towards the top of the pouch and the valve at the bottom of the inner pouch restrict the flow of fluid out of the device.
Implementation Method 2
The device is attached to the animal using flexible adhesive straps/supporters.

AI summary
An animal urine/specimen collection device for home or clinic that allows easy, prolonged use and is leak resistant. A disposable urine collection device and marking deterrent for use by pet owners and veterinarians on animals such as dogs is disclosed. The urine collection device of the present invention is formed from one pouch of flexible plastic material formed into a valve opening at the bottom, being inserted into another pouch of plastic flexible material with no valve formed at the bottom, creating an encapsulating container for liquid that passes through the inner valve pouch due to the outer and inner (valve shaped) pouch layers being sealed at the top peripheral edges. Flexible supporters that are integrally formed to the collection device are drawn up to secure on the back near the hind quarters for male animals, and around the legs and thighs, then on the back for female animals.
