Solution Overview

Problem

Existing outdoor cooking setups, such as barbeques, often require constant manual attention to prevent meat from overcooking or burning, leading to uneven cooking and limiting participant engagement, while also being cumbersome and lacking portability.

Innovation Solution

A demountable and portable electric rotating spit grill with a central pillar, holder arm, and geared motor, featuring a unique fixing mechanism and prongs that allow for compact, lightweight, and easy assembly, enabling consistent and even cooking without vertical supports, powered by a variety of energy sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manual grill is used, then the cook can monitor the meat, but the meat is cooked unevenly and the cook is limited in participation in other activities

Engineering Contradiction:
Improvecooking consistencyVSAvoidcook freedom
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The spit grill incorporates a rotating mechanism that dynamically moves the meat through the cooking zone, transforming the static manual monitoring approach into an automated dynamic system. The rotation ensures all surfaces of the meat are exposed to heat evenly, achieving consistent cooking while freeing the cook from continuous manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating spit grill is designed to automatically rotate and position the meat itself, making the cooking process self-regulating. The mechanical rotation system serves the function of even heat distribution without requiring continuous human operation, allowing the cook to participate in other activities while maintaining reliable cooking results.

Inventive Principle:
Principle #25Self-service

2Reliability

If a traditional rotating spit grill is used, then the meat is cooked evenly, but the device is cumbersome and lacks portability

Engineering Contradiction:
Improvecooking qualityVSAvoiddevice portability
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The spit grill is divided into separate modular components including the rotating spit mechanism, the support structure, and the mounting system. This segmentation allows each component to be optimized independently and enables easy assembly and disassembly for portability while maintaining the functional integrity of the rotating cooking mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a fixed, ground-based grill structure to a portable, suspendable design that utilizes vertical space and alternative mounting dimensions. The ability to hang the grill from trees or portable stands eliminates the need for heavy ground-based infrastructure, achieving both cooking reliability and portability.

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

3Stability of the object's composition

If a fixed grill structure is used, then stable cooking is achieved, but the grill cannot be easily moved or set up in different locations

Engineering Contradiction:
Improvecooking stabilityVSAvoidlocation flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting system is designed to be dynamically adaptable rather than statically fixed. The grill can be securely mounted to various surfaces including trees, portable stands, or ground anchors, allowing the stability characteristics to be adjusted and optimized for different outdoor environments while maintaining secure, stable cooking operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spit grill incorporates a universal mounting system that can interface with multiple types of supports and surfaces. The same basic grill structure can be installed in diverse locations using different mounting methods, achieving both cooking stability and location versatility without requiring location-specific customizations.

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