Compact Urine Bag With Nested Folding And Pull Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine bags are not compact or discrete enough for easy carrying and use, particularly for individuals with reduced dexterity, as they maintain large plane dimensions even when folded, making them cumbersome and difficult to handle.
Innovation Solution
A method for folding and unfolding urine bags into a compact state using multiple folding lines as stiffening means, allowing for easy unfolding by applying forces to opposite areas, and a constraining element to maintain the compact configuration, with a connector for attaching to catheters for fluid collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the urine bag is made from a plane foil material with large surface area, then it provides sufficient capacity for fluid collection, but it becomes cumbersome and difficult to carry
Solution Approach 1:
The urine bag is divided into multiple sections through folding lines, creating a segmented structure that can be compacted into a discrete unit while maintaining sufficient capacity when unfolded
Solution Approach 2:
The urine bag is folded and nested within itself multiple times, with each fold creating a smaller configuration, ultimately forming a compact discrete unit that is easy to carry
2Volume of moving object
If the urine bag is folded multiple times to reduce dimensions, then it becomes compact and discrete, but it becomes difficult to unfold
Solution Approach 1:
Folding lines are pre-formed during manufacturing to define precise fold locations and angles, enabling the bag to be easily unfolded by simply pulling at specific points without requiring complex manipulation
Solution Approach 2:
The folding lines act as intermediary structural elements that mediate between the compact folded state and the unfolded state, providing guidance and mechanical advantage during the unfolding process
3Weight of moving object
If the urine bag is made from thin foil material, then it becomes lightweight and compact, but it lacks structural rigidity for easy handling
Solution Approach 1:
The thin foil material is segmented into multiple sections by folding lines, which collectively provide structural rigidity through the distributed fold structure while maintaining the lightweight characteristic of the thin material
Solution Approach 2:
The urine bag combines thin foil material with the structural framework provided by multiple folding lines, creating a composite structure that achieves both lightweight and rigid characteristics

AI summary
The present invention relates to a collecting device comprising a collecting device for collection of body fluids. The invention relates to a collecting device arranged in a compact configuration wherein the dimensions of the collecting device is small in comparison with the dimensions of the collecting device in an unfolded configuration. In particular the invention relates to a bag having an inner folding and an outer folding. Two pull points may further be arranged so that the application of oppositely directed forces to the first and second pull-points will lead to unfolding of the inner folding. With this arrangement the outer folding may be forced to unfold as the inner folding unfolds.
