Waste Bin Cover System Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste bin covers do not effectively protect bins from freezing water, leading to potential lid sticking issues and interference with the bin's operation.
Innovation Solution
A flexible, water-impermeable cover with a belt strap and flaps that secures to the waste bin, allowing partial opening of the lid without removing the cover, using materials like polyethylene or vinyl, and featuring a hook-and-loop fastener for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flexible fabric cover is used to protect the waste bin, then the cover provides basic protection, but it allows water penetration that causes freezing and lid sticking
Solution Approach 1:
The patent uses a flexible plastic wrap or film cover instead of traditional fabric covers. This thin film is water-impermeable, preventing water from penetrating to the lid and causing freezing. The flexibility of the film allows it to conform to the bin shape while maintaining complete water protection, resolving the contradiction between providing protection and preventing water infiltration.
Solution Approach 2:
The patent employs a disposable plastic wrap or film that is discarded after a single use. This inexpensive, single-use cover provides effective water protection without requiring durable construction. The disposable nature allows for complete water-tight sealing without complex fastening mechanisms, ensuring reliable lid operation while preventing freezing.
2Object-affected harmful factors
If the cover is secured tightly to prevent water penetration, then water protection is improved, but access to the bin becomes difficult
Solution Approach 1:
The patent divides the cover into multiple sections: a main body that secures tightly to the bin and a separate flap or opening mechanism that provides access. The main cover remains tightly secured to prevent water penetration, while the segmented access flap can be independently opened to reach the bin contents. This segmentation resolves the contradiction between tight sealing and ease of access.
Solution Approach 2:
The patent introduces an intermediary access mechanism such as a flap, opening, or removable panel that mediates between the tightly secured cover and the need for bin access. This intermediary element allows users to access the bin without compromising the water-tight seal of the main cover, resolving the contradiction between protection and accessibility.
3Ease of operation
If the cover is designed to be removable for complete access, then bin accessibility is improved, but the cover cannot remain on the bin during operation
Solution Approach 1:
The patent employs a dynamic cover system that can transition between a secured state during operation and a removed state for access. The cover includes a fastening mechanism that securely attaches to the bin during normal operation, preventing water penetration. When access is needed, the same mechanism can be quickly released to remove the cover completely. This dynamic capability resolves the contradiction between security during operation and accessibility when needed.

AI summary
A waste bin cover system for protecting a waste bin from interference from freezing water includes a waste bin with a lid for opening and closing an aperture at a top end of the bin. A cover is deployable over the lid and a rim of the waste bin when the lid is closed to protect the waste bin from interference from freezing water. The cover has a pair of flaps in front which are removably couplable to each other to secure the cover to the waste bin.
