Solution Overview

Problem

Existing corn roasters fail to evenly roast corn on the cob due to inadequate heating elements and holding mechanisms, which do not properly secure corn in place, especially for varying sizes.

Innovation Solution

A corn roaster assembly with a cylindrical tube structure, a heating element positioned around a rack, and a removable cage with semicircular apertures forming cylindrical receptacles, secured by spring elements or prongs, to hold and evenly roast corn cobs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If corn is placed horizontally on supporting rods, then the device structure is simple, but the corn is not evenly roasted

Engineering Contradiction:
Improvedevice structureVSAvoidevenness of roasting
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The corn roasting device is segmented into multiple functional components: a cylindrical receptacle for holding corn, a heating element positioned around the receptacle, and a rotatable rack with supporting rods. This segmentation allows each component to perform its specific function optimally - the cylindrical shape ensures even heat distribution, the surrounding heating element provides uniform heating, and the rotatable rack enables consistent rotation of corn cobs for even roasting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates dynamic elements, specifically the rotatable rack that allows corn cobs to be rotated during the roasting process. This dynamic rotation ensures that all surfaces of the corn come into contact with the heating element uniformly, solving the problem of uneven roasting that occurs with static horizontal placement.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If a heating element is positioned around the rack, then even roasting is achieved, but the device complexity increases

Engineering Contradiction:
Improveevenness of roastingVSAvoidheating element positioning
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating element is strategically positioned in specific locations around the cylindrical receptacle to optimize heat distribution. By placing the heating element circumferentially around the rack, the device ensures that heat is applied uniformly to all sides of the corn cobs during rotation, achieving even roasting without requiring complex multi-directional heating systems.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If spring elements or prongs are used to secure corn, then corn of varying sizes is held properly, but the device complexity increases

Engineering Contradiction:
Improveaccommodation of varying corn sizesVSAvoidholding mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holding mechanism incorporates spring elements that provide dynamic, adaptive support for corn cobs of varying sizes. The springs can compress and extend to accommodate different corn diameters, while prongs provide stable positioning. This dynamic holding system ensures that corn is securely held in the correct orientation for even roasting, regardless of size variations.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If corn is laid horizontally, then the device structure is simple, but the heating efficiency is inadequate

Engineering Contradiction:
Improvestructural simplicityVSAvoidheating efficiency
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The device transforms the static horizontal laying of corn into a dynamic rotating motion. The rotatable rack allows corn cobs to be rotated during heating, ensuring that all surfaces are exposed to the heating element uniformly. This dynamic approach significantly improves heating efficiency and energy utilization compared to static horizontal placement, as heat is applied consistently to the entire surface area of each cob.

Inventive Principle:
Principle #15Dynamics
