Solution Overview

Problem

Existing grills lack a simple and efficient mechanism to switch between direct and indirect grilling methods while also failing to optimize energy usage and food flavor enhancement.

Innovation Solution

A guide plate with a rounded area and inclined sections, featuring indentations and slots for liquid drainage and air flow, which can be easily inserted and removed from a gas grill without tools, allowing for energy-efficient indirect cooking and enhanced flavor through controlled air circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex mechanism with multiple components is used to switch between direct and indirect grilling, then the grilling functionality is improved, but the device complexity increases

Engineering Contradiction:
Improvegrilling method switching capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grill system is segmented into functionally independent components: a removable guide plate for indirect grilling, a separate direct grilling configuration, and modular burner arrangements. This allows users to switch between grilling methods by simply adding or removing the guide plate rather than operating a complex mechanical switching mechanism, thus maintaining versatility while reducing device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grill system employs dynamic reconfigurability where the guide plate can be easily inserted and removed to change grilling modes. This dynamic approach allows the system to adapt between direct and indirect grilling configurations without requiring complex fixed mechanisms, achieving versatility through simple, flexible component arrangement

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If traditional grilling without optimized heat distribution is used, then the device complexity is reduced, but the energy efficiency deteriorates

Engineering Contradiction:
Improveenergy efficiencyVSAvoidheat distribution structure
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The guide plate features locally optimized characteristics with specific geometric designs including curved surfaces and strategically positioned openings that enhance heat distribution efficiency. These local quality improvements optimize thermal performance without requiring a complete redesign of the entire grill structure, thus improving energy efficiency while limiting the increase in overall device complexity

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The guide plate acts as an intermediary heat distribution element between the burners and the food. It mediates heat flow by directing and diffusing thermal energy uniformly across the grilling surface, improving energy efficiency without requiring direct modification of the burners or complex integrated heat management systems

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a fixed grill structure is used, then the ease of operation is improved, but the adaptability deteriorates

Engineering Contradiction:
Improvegrilling method variabilityVSAvoidstructure modification ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The grill system transitions from a fixed structure to a dynamically reconfigurable one by incorporating a removable guide plate. This allows the structure to adapt between different grilling configurations (direct and indirect grilling) simply by adding or removing the plate, maintaining ease of operation while significantly improving adaptability

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a grill, for example a gas-powered grill according to the preamble of claim 1, for barbecuing, cooking or baking food on a grill grate or similar, particularly for use outdoors. It comprises a burner chamber (2) in which a burner arrangement (3) is provided, said burner chamber (2) having a foldable hood (5) that covers the grill grate (6) when closed. This should achieve simple and reliable conversion between direct and indirect grilling, and allow simultaneous, energy-saving direct and indirect grilling. The grill is provided with a baffle plate (14) made in a desired width in the direction of a main axis (17) of the burner chamber (2), covering at least one part of the burner arrangement (3), and being designed to extend between the front side and the rear wall of the burner chamber (2) and to lie on inner edges of the burner chamber (2).
