No-Flip Flat Bread Cooking Using Rotational Heating Element

Solution Overview

Problem

Conventional cooking devices for flat bread require flipping, which increases size and weight, making it impractical for compact portable appliances to achieve even cooking without bulk.

Innovation Solution

A platen system with adjustable temperature profiles and movement sequences, allowing for uneven heat distribution and cooking without flipping, using multiple platens with specific surface structures and individual temperature control, optimized by software based on flour quality, water content, and recipe selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If flipping mechanism is added to cook both sides of flat bread, then cooking evenness is improved, but device size and weight increase

Engineering Contradiction:

Improvecooking evennessVSAvoiddevice weight

Core Design Contradiction:

Manufacturing precisionVSWeight of moving object

Solution Approach 1:

Instead of flipping the flat bread to cook both sides, the patent inverts the approach by having the heating element flip to cook alternating sides of the dough. The heating element rotates 180 degrees to apply heat to the opposite side, eliminating the need for mechanical flipping of the food while achieving even cooking on both sides.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the mechanical flipping system with a thermal field rotation system. Instead of mechanically flipping the heavy dough product, a lighter heating element with rotational capability is used to alternately apply heat to different sides, substituting a heavy mechanical operation with a lighter thermal field operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If flipping mechanism is added to cook both sides of flat bread, then cooking evenness is improved, but device complexity increases

Engineering Contradiction:

Improvecooking evennessVSAvoidmechanical complexity

Core Design Contradiction:

3Adaptability or versatility

If multiple platens with individual temperature control are used, then cooking adaptability is improved, but device size increases

Engineering Contradiction:

Improvecooking adaptabilityVSAvoiddevice volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent employs dynamic temperature control where the heating element can be independently controlled and rotated to different positions. The system dynamically adjusts which side receives heat and at what temperature, allowing adaptability to different cooking requirements without requiring multiple static heating zones that would increase device volume.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The single heating element serves multiple functions by rotating to different positions and adjusting temperature independently. It can cook either side of the dough, provide different temperature zones, and adapt to various cooking scenarios, replacing the need for multiple dedicated heating elements that would increase device size.

Inventive Principle:

Principle #6Universality (Multi-functionality)
