Solution Overview

Problem

Existing grills with continuous cooking surfaces struggle to maintain different temperature zones effectively due to heat conduction between regions, making it difficult to cook foods at varied temperatures simultaneously.

Innovation Solution

A grill design featuring individually controllable heating zones separated by isolation zones with cooling channels to reduce heat conduction, allowing for independent temperature control of each zone and easy movement of food across the continuous surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a continuous cooking surface is used with heating elements beneath, then the cooking surface provides a large area for cooking, but heat conduction between regions causes temperature zones to merge and prevents independent temperature control

Engineering Contradiction:
Improvecooking surface areaVSAvoidtemperature zone independence
Core Design Contradiction:
Area of stationary objectVSTemperature

Solution Approach 1:

The continuous cooking surface is segmented into discrete heating zones by inserting thermally isolating bars between adjacent heating elements. These bars divide the cooking surface into independent temperature zones while maintaining the overall continuous surface structure, allowing each zone to be controlled at different temperatures without heat interference from neighboring zones.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Thermally isolating bars serve as intermediary elements positioned between adjacent heating zones. These bars act as thermal barriers that prevent heat conduction between zones while maintaining structural continuity of the cooking surface, enabling independent temperature control of each heating zone.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If thermally isolating bars are inserted between heating zones, then temperature zone independence is improved, but the cooking surface continuity is disrupted

Engineering Contradiction:
Improvetemperature zone independenceVSAvoidcooking surface continuity
Core Design Contradiction:
TemperatureVSArea of stationary object

Solution Approach 1:

The thermally isolating bars are designed with upper surfaces that are substantially coplanar with the adjacent cooking surface plates, creating a flush transition. This design maintains the visual and functional continuity of the cooking surface while the bars themselves provide thermal isolation between heating zones.

Inventive Principle:
Principle #30Flexible shells and thin films
