Solution Overview

Problem

Benchtop or countertop ovens occupy valuable counter space and pose a risk of burns when removing racks after cooking, as existing solutions do not effectively address the space efficiency and safe extraction of racks.

Innovation Solution

An oven with a paramagnetic rack and a door equipped with a magnet that engages and attracts the rack for easy extraction, combined with a space-saving cutting board or tray that interlocks with the oven's surface, reducing heat exposure and optimizing counter space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rack is fully removed from the oven for access or cooling, then the user can access the food item, but the user may be burned during the process

Engineering Contradiction:
Improverack accessibilityVSAvoidburn risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The magnetic engagement mechanism automatically pulls the rack forward to a partial removal position before the user needs to access it, preparing the rack in a safe position that reduces burn risk while maintaining accessibility

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If a benchtop or countertop oven is used, then the oven can be conveniently used to warm or cook food, but the oven occupies valuable counter space

Engineering Contradiction:
ImproveconvenienceVSAvoidcounter space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The cutting board is designed to serve multiple functions: it provides a workspace surface, acts as a heat-resistant surface for placing hot items, and when equipped with magnetic elements, can interact with the oven's magnetic field to assist in rack extraction, thereby reducing the need for additional tools and minimizing counter space requirements

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Facilitates safe and partial removal of racks from ovens, conserves counter space by using a magnetically assisted extraction mechanism and a heat-resistant, interlocking cutting board or tray that maintains a safe distance from heat sources.

Implementation Method 1

at least one frame element comprises a magnet. The magnet is adapted to engage and attract the front portion of the rack
