Solution Overview

Problem

Conventional grills lack effective temperature control over different regions of a continuous cooking surface, leading to difficulties in maintaining distinct temperature zones due to heat conduction between adjacent areas.

Innovation Solution

A grill with individually controllable heating zones separated by isolation zones that incorporate cooling fluid channels, allowing for independent temperature control of each zone through a cooling fluid circulation system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a continuous cooking surface is used with heating elements positioned beneath it, then the cooking surface can be heated, but it becomes difficult to maintain distinct temperature zones due to heat conduction between adjacent areas

Engineering Contradiction:
Improvetemperature controlVSAvoidheat conduction between zones
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The continuous cooking surface is divided into multiple heating zones, each with its own independently controllable heating element. This segmentation allows different temperature settings for different regions of the cooking surface, enabling precise temperature control for various cooking needs simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Isolation zones are introduced between adjacent heating zones to act as thermal barriers. These isolation zones prevent excessive heat conduction between neighboring heating zones, allowing each zone to maintain its desired temperature independently while still being part of a continuous cooking surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If heating zones are separated by isolation zones with cooling fluid channels, then temperature control precision is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature management precisionVSAvoidcooling fluid circulation system
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

Cooling fluid channels are embedded within the isolation zones to actively manage heat transfer. By circulating cooling fluid through these channels, the system can precisely control the temperature in isolation zones, enhancing the thermal separation between heating zones and improving overall temperature management precision.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The cooling fluid circulation system is integrated directly into the structure of the isolation zones, combining the thermal barrier function with active cooling capability. This merging of functions allows the isolation zones to serve both as physical separators and as active thermal management components, reducing the need for separate cooling systems.

Inventive Principle:
Principle #5Merging (Combining)
