Device for the prevention of cooking boilover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking vessels often experience boilovers due to starch release during boiling, leading to safety hazards and messes, with existing solutions like wooden spoons being ineffective and prone to bacterial growth.
Innovation Solution
A device with a center portion having a concave upper surface and a convex lower surface with holes, designed to traverse the top of a cooking vessel, reducing foam buildup by breaking surface tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wooden spoon is placed over the pot to prevent boilover, then the boilover is reduced to some degree, but the spoon absorbs steam and starch leading to bacterial and mold growth
Solution Approach 1:
The patent describes a disposable aluminum foil-based boilover preventer that is discarded after single use. This eliminates the hygiene problem of reusable wooden spoons by ensuring the prevention device is always clean and sterile, while still providing effective boilover prevention through its foil construction that can be crimped to the pot rim.
Solution Approach 2:
The invention changes the material parameter from organic wood to inorganic aluminum foil, which does not absorb moisture or starch. This parameter change prevents the biological degradation and bacterial growth that occurs with wooden spoons while maintaining the mechanical function of disrupting foam bubbles.
2Reliability
If multiple wooden spoons are used to improve boilover prevention, then the effectiveness increases, but the complexity of the solution and cleaning/maintenance burden increases
Solution Approach 1:
The disposable foil preventer is designed to be used once and then discarded, eliminating the need for multiple spoons and the associated cleaning and storage complexity. A single inexpensive foil device provides sufficient protection without requiring maintenance.
Solution Approach 2:
The invention extracts only the essential function of boilover prevention from the wooden spoon concept, removing the problematic material properties (wood) and keeping only the functional requirement (disrupting foam). This results in a simpler, more effective solution that doesn't require multiple components.
3Duration of action of stationary object
If the wooden spoon is used continuously, then it provides ongoing boilover protection, but the steam and heat change the shape of the wood making it less useful
Solution Approach 1:
The foil-based preventer is designed for single-use duration, which is sufficient for most cooking operations. After use, it is discarded rather than reused, avoiding the shape degradation problem that occurs with continuous use of wooden spoons. The low cost of the foil material makes disposable use economically viable.
Solution Approach 2:
The invention changes the material parameter from wood (organic, deformable under heat) to aluminum foil (inorganic, heat-resistant). This parameter change allows the preventer to maintain its shape and structural integrity throughout the cooking process without the deformation issues that plague wooden spoons.

AI summary
A device for the prevention of cooking boilover is disclosed. The device is placed on a cooking vessel while in use to disrupt building surface tension in a boiling liquid, and thus reduce or eliminate the tendency for the cooking vessel to boil over. The device for the prevention of cooking boilover (“boilover preventer”) has a first supporting member and a second supporting member with a center portion joined to each supporting member and having a generally concave upper surface with holes there through.
