Rigid Waste Bin Liner With Rim-Locking Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waste bins often become soiled and difficult to clean due to direct contact with waste, leading to sanitary hazards and unpleasant odors, especially when no flexible bag liner is used, and existing solutions are either ineffective or costly to replace.
Innovation Solution
A rigid waste bin liner with hook parts that extend over and under the perimeter rim of the bin, locking in place and serving as both a protective layer and lifting handles, allowing for easy removal and disposal while reducing cleaning burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid liner is inserted into a waste bin, then protection against waste contact is improved, but cleaning difficulty increases
Solution Approach 1:
The patent applies the disposable principle by providing a rigid liner that is intended to be replaced rather than cleaned. The liner includes a disposable bag nested within it, and the entire assembly is designed to be removed and discarded after use, eliminating the cleaning burden on the bin itself. This resolves the contradiction by sacrificing the durability of the liner for the ease of cleaning the bin.
Solution Approach 2:
The patent segments the liner system into multiple components: an inner disposable bag and an outer rigid liner with hook parts. This segmentation allows the inner bag to be disposed of separately from the outer liner, enabling the bin to be cleaned while maintaining protection during use. The segmented design addresses the contradiction by separating the protective function from the cleaning requirement.
2Reliability
If hook parts are extended over and under the perimeter rim, then securing reliability is improved, but device complexity increases
Solution Approach 1:
The hook parts serve multiple functions: they secure the liner to the bin by extending over and under the perimeter rim, and they simultaneously provide lifting handles for removing the liner. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while maintaining securing reliability.
Solution Approach 2:
The patent merges the securing function and lifting function into a single integrated hook part structure. The hook parts are formed as continuous elements that both engage with the bin rim and extend outward to serve as handles, combining multiple functions into one component to minimize complexity.
3Ease of operation
If a disposable liner is used, then cleaning burden is reduced, but cost increases
Solution Approach 1:
The patent uses a flexible disposable bag nested within the rigid liner. This thin film approach provides effective protection and disposal functionality while minimizing material usage and cost. The flexible bag conforms to the rigid liner's shape, providing adequate protection without excessive material consumption.
Solution Approach 2:
The patent employs a disposable bag that is inexpensive and intended for single use. This disposable component transfers the contamination burden from the bin to the bag, which can be easily discarded. The low cost of the disposable bag makes the overall system economically viable despite the continuous consumption of liners.

AI summary
Waste bin liners, such as rigid liners, methods of using waste bin liners, and combinations of waste bins with a liner, are disclosed. In one example hook parts of a waste bin liner are extended in sequence over and under a perimeter rim of a waste bin, and laterally inward of a part of the perimeter rim. In one example a rigid liner has multi-purpose hook parts that lock to the rim of a waste bin, and also form lifting handles for removing the liner from the bin.
