Adjustable Sink Cover with Sliding Mechanism for Pathogen Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Kitchen sinks are often the dirtiest place in a home, harboring a high number of bacteria and other pathogens, and can spread odors and contaminants to other areas.
Innovation Solution
A sink cover designed to fit over the sink basin, featuring an edge portion that contacts the sink rim, a lip portion that extends beyond the rim, and a sliding mechanism to adjust length, along with optional features like a thermochromic top, handles, and a ratchet-like fastening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sink cover is provided to isolate sink contents, then pathogen spread and odor contamination are reduced, but device complexity increases due to sliding mechanisms and adjustable components
Solution Approach 1:
The sink cover incorporates a sliding mechanism that allows the cover length to be dynamically adjusted. The cover can extend to cover the entire sink basin when needed for isolation, and retract when access is required. This dynamic adjustment resolves the contradiction by providing full coverage for pathogen and odor isolation only when necessary, rather than maintaining constant full coverage structure.
Solution Approach 2:
The sink cover is divided into separate sections that can slide relative to each other. This segmentation allows the cover to be adjusted in length by sliding portions together or apart, enabling the cover to adapt to different coverage needs while reducing structural complexity compared to a fixed full-coverage design.
2Adaptability or versatility
If the sink cover length is made adjustable to fit different sink sizes, then adaptability improves, but device complexity increases due to sliding mechanisms
Solution Approach 1:
The sliding mechanism enables the sink cover to dynamically change its length to adapt to different sink sizes. Users can extend the cover to cover larger basins or retract it for smaller sinks, providing versatility without requiring multiple fixed-size covers.
Solution Approach 2:
The adjustable sliding mechanism allows a single sink cover design to serve multiple sink sizes and configurations. The cover can be extended to cover entire basins or retracted to cover only portions, making one product universally applicable to various sink types and sizes.
3Object-affected harmful factors
If the sink cover is made solid to provide a clean surface for food preparation, then sanitation improves, but ease of operation decreases due to reduced flexibility
Solution Approach 1:
The sink cover maintains a solid top surface for sanitation when extended for food preparation, but can be retracted or folded back when not needed. This dynamic configuration allows the solid surface to provide continuous sanitation protection during use while allowing easy access to the sink when the cover is retracted.
Solution Approach 2:
The cover is segmented into a solid top portion and adjustable side portions. The solid top maintains sanitation for food preparation, while the segmented sides can be slid or folded to provide access flexibility without compromising the integrity of the solid sanitary surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sink cover effectively isolates the sink contents from the rest of the kitchen, reducing the spread of pathogens and odors, while also providing a clean and sanitary surface for food preparation and storage.
Implementation Method 1
The sink cover may further include a pigment that changes color based on a temperature of the sink cover
Implementation Method 2
At least one of the edges, lip portion, and top portion include a heat insulating material

AI summary
A sink cover includes an edge portion shaped to contact the circumference of a sink rim. The edge portion includes an inner cover and an outer cover, with the outer cover configured to constrain the inner cover to slide along a longitudinal axis relative to the outer cover. The sink cover may further include a fastening mechanism that prevents the inner and outer covers from separating beyond a specified distance along the longitudinal axis. The fastening mechanism can consist of a first projection on the inner cover and a second projection on the outer cover, which make contact when the covers are separated to the specified distance. The outer cover may feature a track to constrain the first projection to the longitudinal axis, and this track can include a pair of longitudinal protrusions aligned with the longitudinal axis to prevent movement along a traverse axis perpendicular to the top portion.
