Flexible Oven Convection Insert for High-Heat Even Baking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens lack the ability to reach high-heat temperatures, leading to dehydration of food items and limitations in cooking size and evenness, with existing heat-directing inserts being rigid and inflexible, making them unsuitable for various oven sizes and requiring excessive storage space.
Innovation Solution
A universal convection manipulation device comprising a flexible, rectangular sheet of material with flanges that can be flexed into an arched shape to fit various oven sizes, creating a high-heat environment by aligning with sidewall support structures and allowing for secure tension retention, thus enhancing convection currents and radiant heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If rigid heat-directing inserts are used, then heat convection is improved, but storage space requirement increases and adaptability to different oven sizes decreases
Solution Approach 1:
The patent applies the dynamics principle by making the heat-directing insert flexible rather than rigid. The insert can be bent into different arch configurations to adapt to various oven sizes and shapes. This flexibility allows the same insert to be universally applied across different conventional ovens, resolving the contradiction between maintaining effective heat convection and adapting to different oven dimensions.
Solution Approach 2:
The patent changes the physical parameter of the insert from rigid to flexible, enabling it to assume different shapes and sizes. This parameter change allows the insert to conform to various oven interiors while maintaining its heat-directing function, thus achieving both effective heat convection and adaptability to different oven sizes.
2Temperature
If rigid heat-directing inserts are used, then heat convection is improved, but storage space requirement increases
Solution Approach 1:
The patent employs a flexible sheet material to create the heat-directing insert. This flexible construction allows the insert to be collapsed or folded into a compact form for storage, dramatically reducing the storage space required compared to rigid inserts. When deployed, it maintains its arch shape to effectively direct heat and improve convection.
3Use of energy by moving object
If conventional ovens are used, then energy consumption is reduced, but temperature capability decreases leading to food dehydration
Solution Approach 1:
The patent uses an arched or curved configuration of the flexible insert to trap and concentrate heat within the oven chamber. This curvature creates a more efficient heat circulation pattern that allows conventional ovens to achieve higher effective temperatures for cooking, preventing food dehydration while maintaining lower energy consumption compared to commercial ovens.
4Volume of moving object
If small rigid inserts are used, then storage space is reduced, but cooking space and convection current effectiveness decrease
Solution Approach 1:
The flexible insert can be expanded to fill a larger volume when deployed in the oven, providing adequate cooking space and effective convection currents. When not in use, it collapses to a compact form for storage. This dynamic size change resolves the contradiction between minimizing storage space and maximizing cooking space effectiveness.

AI summary
A universal convection manipulation device for insertion into a conventional oven and a method of use are provided. The universal convection manipulation device includes a substantially rectangular flexible sheet of material including an intermediate body portion. The intermediate body portion includes a first flange arranged along an end of the intermediate body portion and a second flange arranged along an opposite end of the intermediate body portion. The flexible sheet of material is capable of being flexed into an arched shape and sized to be insertable into various sized conventional ovens depending on the amount of flexure of the sheet of material. The first flange and the second flange are shaped so that they are capable of being inserted and held with a tension against a sidewall support structure of a conventional oven when the flexible sheet of material is flexed into the arched shape and released during installation within the conventional oven. The flexible sheet of material lies substantially flat in a relaxed, unflexed condition.
