Solution Overview

Problem

Conventional grilling devices require manual rotation and monitoring to ensure even cooking, which can be time-consuming and labor-intensive.

Innovation Solution

A deployable grill with a support frame and spit rods that can be rotated using a drive system, allowing for automated cooking with a heating element positioned adjacent to the spit rods, enabling efficient and even cooking without constant user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual rotation and monitoring is used for grilling, then the cooking process can be controlled, but it requires constant user intervention and time

Engineering Contradiction:
Improveautomation of rotationVSAvoidcomplexity of grill system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The spit rod is designed to rotate automatically through a hinge assembly that converts the reciprocating motion of the support member into rotational motion of the spit rod, enabling self-service rotation without requiring external motors or complex drive systems

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The hinge assembly dynamically converts linear reciprocating motion of the support member into rotational motion of the spit rod, creating an automated rotation system that adapts to the cooking process without requiring complex mechanical drive systems

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If flat pan or flat grates are used, then the structure is simple, but the food requires manual moving or flipping to cook evenly

Engineering Contradiction:
Improveease of cooking operationVSAvoidtime for manual monitoring
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The spit rod configuration allows food to be skewered and rotated automatically, enabling self-service cooking where the food turns itself evenly without requiring manual flipping or monitoring by the user

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The dynamic rotation of the spit rod through the hinge assembly provides continuous movement that ensures even cooking of food without requiring manual intervention to flip or reposition the food items

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the support member is fixed in position, then the structure is stable, but the grill cannot be deployed or stowed

Engineering Contradiction:
Improvedeployability of grillVSAvoidstability of support member
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The support member is designed with movable connections to the support frame, allowing it to reciprocate between deployed and stowed positions while maintaining stability during each position through the mechanical constraints of the hinge assembly and bracket structure

Inventive Principle:
Principle #15Dynamics

AI summary

A deployable grill including a support frame having a support member operable between a stowed position and a deployed position. First and second brackets outwardly extend from the support member and are spaced-apart from one another to define a receiving area therebetween. A heating element is disposed on the support member adjacent to the receiving area. At least one spit rod is received in the receiving area.
