Liquid Capture Device Holder and Bag Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for capturing bodily fluids, such as urine, face challenges including leakage, difficulty in use for individuals with reduced dexterity or mobility, and the need for assistance, particularly for those with impaired manual dexterity or visual impairment, leading to adverse health and quality of life impacts.
Innovation Solution
A self-contained liquid capture device with a holder and collection bag system that features secure attachment mechanisms, a shape conforming to the human body for ease of use, an angled arm for improved handling, and a collection bag attachment system allowing single-handed operation and easy removal, designed to be used in various orientations and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If non-invasive worn absorbent devices are used, then fluid absorption is improved, but skin contact issues and leakage occur
Solution Approach 1:
The invention extracts the collection bag from direct skin contact by introducing a holder that interfaces with the body while the bag remains suspended. Urine is directed from the holder into the bag, eliminating prolonged skin contact and associated problems while maintaining absorption functionality.
Solution Approach 2:
The device is segmented into distinct functional components: a holder for body interface, a collection bag for fluid storage, and a closure system. This segmentation allows each component to be optimized independently - the holder for comfort and fit, the bag for capacity and leakage prevention.
2Quantity of substance
If non-invasive non-worn devices are used, then urine capture is achieved, but ease of use and accessibility are reduced
Solution Approach 1:
The device is designed for independent use by individuals with impaired dexterity. The holder can be self-applied, the collection bag can be attached and detached easily, and the closure mechanism can be operated with minimal manual dexterity requirements, enabling users to manage their own toileting needs.
Solution Approach 2:
The closure mechanism uses a simplified parameter change approach - moving from complex multi-step closures to a single-action closure system that can be operated with limited dexterity. The attachment mechanism between holder and bag also uses simplified mechanical parameters for easy connection and disconnection.
3Reliability
If invasive devices such as catheters are used, then urine capture is reliable, but infection risk and user independence are reduced
Solution Approach 1:
The invention extracts the collection bag from direct body insertion, using instead a holder that interfaces with the body externally and directs urine into the bag. This eliminates the need for invasive catheter insertion while maintaining reliable urine capture functionality.
4Reliability
If secure attachment mechanisms are used, then leakage is reduced, but device complexity increases
Solution Approach 1:
The attachment mechanism between holder and collection bag uses simplified mechanical parameters - a collar that fits over a protrusion with a single closure action. This provides secure attachment and leakage prevention while avoiding complex multi-component fastening systems.
