Microwave Splatter Cover With Venting and Magnetic Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microwave oven covers or enclosures fail to effectively inhibit food and liquid splattering, become excessively hot, take up kitchen space, and lack ergonomic design for easy handling and storage.
Innovation Solution
A reusable microwave oven cover or enclosure with a magnet assembly for storage inside the oven, a structurally supported rim for easy gripping, and ventilation features to reduce steam buildup, along with a magnet configuration that enhances magnetic pull strength and minimizes space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic plate cover or splatter guard assembly is used, then splatter inhibition is improved, but the cover becomes extremely hot to the touch and takes up excessive space in the kitchen cabinet
Solution Approach 1:
The cover is divided into a base portion and a domed portion that can be separated. The domed portion can be removed for washing or storage, reducing the space occupied by the cover when not in use and allowing better heat dissipation from the base portion that remains in the microwave.
Solution Approach 2:
The cover transitions from a flat planar structure to a three-dimensional domed shape. This dimensional change creates internal volume for steam escape and reduces contact area with hot surfaces, thereby reducing the temperature of the cover while maintaining splatter inhibition effectiveness.
2Reliability
If a splatter guard assembly is used, then splatter inhibition is improved, but the assembly makes food soggy due to steam build-up inside the microwave cover
Solution Approach 1:
The base portion of the cover incorporates a porous structure with numerous small openings distributed throughout. These pores allow steam to escape continuously while still blocking larger food particles and liquid splatters, preventing steam build-up that would otherwise make food soggy.
Solution Approach 2:
Different regions of the cover have different properties: the base portion has a porous structure for steam ventilation, while the domed portion provides a smooth barrier for splatter prevention. This local differentiation allows simultaneous achievement of steam escape and splatter inhibition.
3Reliability
If a conventional microwave oven cover is used, then splatter inhibition is provided, but the cover lacks ergonomic design for easy handling and storage
Solution Approach 1:
The cover is segmented into a base portion and a removable domed portion. This segmentation allows the user to handle only the domed portion when placing or removing the cover from the microwave, improving ease of operation and reducing the risk of burning hands.
Solution Approach 2:
The domed portion can be nested within or alongside the base portion when stored, significantly reducing the space required in the kitchen cabinet. The nested configuration allows the cover to occupy minimal storage space while maintaining full functionality during use.

AI summary
Various reusable microwave oven covers or enclosures configured to inhibit food and liquid splattering during microwave oven cooking or heating. A microwave oven cover assembly may include a housing configured for covering a food item during microwave oven cooking, the housing having a closed end and an open end. The cover assembly may further include a rim coupled to the housing at the open end, the rim having a first rim portion couplable to a second rim portion at a corner to provide structural strength to the rim. The rim can be configured for gripping by a user to move the cover assembly on to or off a food item during microwave oven cooking. Optionally, the cover assembly can include a magnet assembly or a non-magnetic handle assembly for moving or storing the cover assembly.
