Solution Overview

Problem

Conventional barbecues offer limited options for cooking food, particularly for types like shish kebabs that require specific heat arrangements, as they can either be too close to the heat source and char or not close enough, and the warming rack provides inadequate cooking.

Innovation Solution

A barbecue support assembly that allows for an elongate skewer to be positioned at multiple preselected heights above the grill, with body elements and apertures that enable vertical and transverse repositioning, providing multi-level cooking options and stabilizing the skewer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If food is positioned close to the heat source for cooking, then cooking efficiency is improved, but the food may char or blacken

Engineering Contradiction:
Improvecooking efficiencyVSAvoidcharring of food
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces vertical positioning of skewers at multiple heights above the grill, transforming the traditional two-dimensional cooking surface into a three-dimensional cooking space. This allows food to be positioned at optimal distances from the heat source, enabling efficient cooking without charring by utilizing the vertical dimension for heat distance control.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The support assembly allows dynamic adjustment of skewer positions between different height levels, enabling users to adapt the cooking distance in real-time based on food type and cooking stage, thus preventing charring while maintaining cooking efficiency.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If food is positioned on the warming rack far from the heat source, then charring is avoided, but cooking efficiency decreases and minimal cooking occurs

Engineering Contradiction:
Improveavoiding charringVSAvoidcooking efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

By adding vertical positioning capability, the invention creates intermediate cooking zones between the grill and warming rack, allowing food to be positioned at optimal heights for both cooking efficiency and charring prevention simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the barbecue has a flat grill with limited positioning options, then device complexity is reduced, but adaptability for different food types decreases

Engineering Contradiction:
Improvegrill structure simplicityVSAvoidcooking arrangement flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The support assembly is segmented into multiple body elements with apertures at different heights, allowing independent positioning of skewers at various levels. This segmentation provides cooking flexibility for different food types while maintaining relative simplicity of the overall grill structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support assembly serves multiple functions: it provides vertical positioning for skewers, allows transverse repositioning, and accommodates different food types and cooking stages, thereby increasing adaptability without significantly complicating the grill structure.

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

4Device complexity

If the skewer position is fixed, then device complexity is reduced, but the ability to reposition for different cooking needs is limited

Engineering Contradiction:
Improvepositioning mechanism simplicityVSAvoidskewer repositioning flexibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The support assembly incorporates movable components that allow skewers to be repositioned vertically between different height levels and transversely along the grill, providing operational flexibility while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The body elements with apertures serve as intermediary structures that facilitate easy skewer positioning and repositioning, allowing users to adjust skewer locations without complex mechanisms while maintaining structural support.

Inventive Principle:
Principle #24Intermediary (Mediator)
