Bedpan Liner Drawstring Conduit Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedpan liners with drawstrings do not effectively secure the liner closed during disposal, failing to address the need for efficient and economical odor control and infection prevention.
Innovation Solution
A bedpan liner with a drawstring that includes a biodegradable or flexible material construction, featuring a conduit assembly with retractable drawstrings and optional fragrances to secure the liner and manage odors, made from materials like LDPE, PVC, or cloth, ensuring secure closure and odor management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bedpan liner is designed without a drawstring closure mechanism, then the device complexity is reduced and manufacturing cost is lowered, but the liner cannot be securely closed during disposal leading to odor release and potential infection
Solution Approach 1:
The drawstring closure mechanism is integrated directly into the liner structure by forming loops from the liner material itself and threading drawstrings through them. This merging of the closure system with the liner body eliminates the need for separate closure components, reducing device complexity while maintaining reliable closure security during disposal.
Solution Approach 2:
The drawstring loops and closure mechanism are pre-formed during the liner manufacturing process. The drawstrings are threaded through the loops and the knot-tying mechanism is prepared in advance, allowing the user to simply pull the drawstrings to secure the liner. This preliminary preparation ensures reliable closure without requiring complex assembly or additional components during use.
2Object-generated harmful factors
If a bedpan liner includes fragrance to manage odors, then odor control is improved, but the manufacturing cost and material complexity increase
Solution Approach 1:
Fragrance is applied locally to specific areas of the liner where odor generation is most likely to occur, such as the waste containment area. This localized fragrance application provides effective odor control while using less fragrance material compared to treating the entire liner, thereby reducing manufacturing cost and material complexity.
Solution Approach 2:
The liner incorporates fragrance as an integrated component during the manufacturing process, combining the liner material with fragrance-containing compounds. This creates a composite structure where the fragrance is embedded within or attached to the liner matrix, providing sustained odor control without requiring separate fragrance application steps or additional complex manufacturing processes.
3Object-affected harmful factors
If a bedpan liner uses biodegradable or flexible material construction, then hygiene and infection prevention are improved, but the structural strength and durability during disposal may be compromised
Solution Approach 1:
The liner utilizes flexible materials that can dynamically adapt to the contours of the bedpan and the waste it contains. This flexibility allows the liner to conform tightly to the bedpan shape, creating a secure fit that prevents leakage and maintains structural integrity during disposal, while still using biodegradable or flexible materials for infection prevention.
Solution Approach 2:
The liner material properties are optimized by adjusting parameters such as thickness, density, and composition within specific ranges. These parameter changes enable the liner to achieve sufficient structural strength for secure disposal while maintaining the flexibility and biodegradability needed for infection prevention and environmental compatibility.

AI summary
A bedpan liner with drawstring including a liner assembly, a conduit assembly, and a drawstring assembly. The bedpan liner is a flexible liner The bedpan liner has a shape that conforms to the shape of a bedpan. The liner assembly includes an upper portion and a lower portion. The lower portion is used as a waste compartment. The conduit assembly includes a conduit, a first opening and a second opening. The drawstring assembly includes a drawstring. The drawstring is inserted into said first or second opening and goes through the conduit. The drawstring emerges from the first opening and second opening of the edge portion. The drawstring surrounds the edge of the bedpan liner. The conduit slidably contracts along said drawstring to close said liner to secure the bedpan liner during removal and disposal.
