Multi-Liner Receptacle Assembly for Fast Sanitary Liner Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body liquid receptacles require time-consuming and potentially risky cleaning, and while disposable linings reduce waste, the process of wrapping and removing them can be cumbersome.
Innovation Solution
A multi-liner assembly with superimposed lining units, each with an impermeable layer and absorbent material, featuring an attachment mechanism for secure engagement with the receptacle, allowing for easy removal and replacement of individual units, and a rigid support for alignment and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a disposable lining is used to line the body liquid receptacle, then cleaning time and health risks are reduced, but the process of wrapping and removing the lining becomes cumbersome and time-consuming
Solution Approach 1:
The disposable lining is divided into multiple separate lining units that can be individually removed. Each lining unit is independently removable from the receptacle, allowing users to remove only the soiled portion rather than the entire lining assembly, thereby simplifying the removal process and reducing complexity
Solution Approach 2:
The lining units are designed with flexible attachment mechanisms (such as elastic bands or adhesive elements) that allow for easy engagement and disengagement. The dynamic nature of the attachment enables quick installation and removal without complex procedures, making the lining process more user-friendly
2Reliability
If multiple lining units are superimposed in the multi-liner assembly, then continuous use without contamination is ensured, but the device complexity increases
Solution Approach 1:
Multiple lining units are stacked or nested within each other in a compact arrangement. The lining units are positioned one inside another or adjacent to each other in a space-efficient configuration, allowing multiple units to be contained within the receptacle without requiring excessive space or complex structural support
Solution Approach 2:
The multi-liner assembly is designed to accommodate multiple lining units of the same standardized design, allowing the system to provide both sanitary protection through multiple layers and ease of operation through uniform, interchangeable units. The assembly structure serves multiple functions: holding multiple units, facilitating individual removal, and maintaining sanitary barriers

AI summary
A multi-liner assembly for lining a body liquid receptacle includes a plurality of lining units superimposed on one another and engageable with the body liquid receptacle to line a cavity formed therein. Each of the plurality of lining units includes an impermeable layer having a top side with an absorbent material superposed thereon. When the multi-liner assembly is engaged with the body liquid receptacle, a topmost one of the plurality of lining units is exposed and is individually removable from the multi-liner assembly to leave a subsequent one of the plurality of lining units exposed. A multi-liner assembly including a rigid support removably engageable with a body liquid receptacle is also provided. When a rigid support is engaged with the body liquid receptacle, the top side of at least one lining unit is exposed and positioned to line a cavity formed in the body liquid receptacle.
