Waste Receptacle Notched Retention Tabs Cinch Liner Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste receptacles face challenges in securely retaining liners of different sizes and preventing inadvertent detachment, especially when dealing with varying amounts and types of waste.
Innovation Solution
The waste receptacle design includes a rim with a plurality of retention tabs, including notched tabs to secure multiple liners of varying sizes, and a cinch mechanism to keep the liner securely in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single large liner is used in the receptacle, then the receptacle can accommodate larger amounts of waste, but the liner may become loose and detach inadvertently
Solution Approach 1:
The retention tab is segmented into multiple portions (first tab portion, second tab portion, third tab portion) with a notch between them. This segmentation allows the same retention structure to effectively secure both small liners (using outer portions) and large liners (using inner portions), preventing the large liner from becoming loose and detaching while maintaining the ability to hold substantial waste quantities.
Solution Approach 2:
Different portions of the retention tab serve different functions: the first and second tab portions (outer regions) are designed to retain smaller liners, while the third tab portion (inner region) is designed to retain larger liners. This local differentiation allows the retention structure to adapt to different liner sizes and prevent inadvertent detachment of large liners while still accommodating varying waste amounts.
2Adaptability or versatility
If multiple small liners are used in the receptacle, then waste from different sources can be separated, but the liners may not be securely retained
Solution Approach 1:
The retention tab is divided into multiple functional portions with a notch structure. The first tab portion and second tab portion can independently engage with separate small liners placed in different quadrants of the receptacle. This segmentation enables the structure to securely retain multiple small liners simultaneously, preventing them from becoming loose while maintaining the versatility to separate different waste sources.
3Reliability
If the retention structure is designed to securely hold liners, then liner detachment is prevented, but the structure becomes more complex
Solution Approach 1:
Multiple retention functions are merged into a single integrated retention tab structure. The first tab portion, second tab portion, third tab portion, and notch all form one continuous element that provides secure retention for both small and large liners. This merging approach achieves reliable liner retention without the complexity of multiple separate retention components, simplifying the overall structure while maintaining high retention security.

AI summary
A waste receptacle may include a housing, a rectangular rim defining a rim opening, and a plurality of retention tabs extending from the rim. The plurality of retention tabs includes a notched retention tab defining a retention notch between first and second tab portions. The first and second tab portions are configured to respectively retain first and second liners received within the rim opening being diagonally opposed. The plurality of retention liners is configured to receive a larger third liner. The waste receptacle may include a cinch extending from the rim. The cinch may include a cinch base defining a pair of openings, and a cinch tab between the openings. The cinch tab may extend from the cinch base. The cinch is configured to receive a portion of a liner received in the rim opening between the openings and across the cinch tab.
