Solution Overview

Problem

Existing insulators for residential oven flues require adhesives or fasteners to secure them in place, which can be inconvenient and may not effectively manage high temperatures, while also failing to provide comprehensive protection against heat transfer.

Innovation Solution

A bendable insulating body with expandable cuts forming openings that allow the flue to be inserted, creating elastic forces to grip the flue without additional securing methods, providing thermal protection and alignment with the surrounding environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesives or fasteners are used to secure the insulator in place, then the insulator can be held firmly on the flue, but the installation becomes more complex and may not effectively manage high temperatures

Engineering Contradiction:
Improvesecuring effectivenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insulator body is designed with an integrated gripping mechanism that secures itself to the flue without requiring external adhesives or fasteners. The elastic force generated by the bent insulator body automatically clamps onto the flue, making the insulator self-securing and eliminating the need for additional securing components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The insulator utilizes elastic deformation as a key parameter to achieve securing. By bending the insulator body to a specific degree, elastic force is generated that enables the insulator to grip the flue securely. This parameter change from rigid to elastically bent state allows the insulator to adapt and secure itself without additional fastening mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the insulator is designed to accommodate various flue shapes and sizes, then versatility is improved, but the structural complexity increases

Engineering Contradiction:
Improveflue shape accommodationVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The insulator body is designed with flexibility and bendability, allowing it to dynamically adapt to different flue shapes and sizes. Rather than creating multiple rigid insulator variants for different flue configurations, a single flexible insulator design can be bent and shaped to fit various flue geometries, simplifying the overall product line while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The insulator employs a flexible blanket-like structure that can be bent and conform to different flue shapes. This flexible shell approach allows the insulator to adapt to circular, rectangular, or irregular flue cross-sections without requiring complex adjustable mechanisms or multiple specialized designs.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the insulator provides comprehensive thermal protection, then thermal isolation is improved, but the weight and bulk of the insulator increase

Engineering Contradiction:
Improvethermal protection effectivenessVSAvoidinsulator weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The insulator applies thermal protection locally where it is most needed - surrounding the flue in critical heat exposure zones. The insulator blanket is positioned to provide targeted thermal isolation around the flue perimeter and at key heat transfer points, rather than uniformly insulating entire cabinet surfaces, thereby reducing overall material usage while maintaining effective thermal protection.

Inventive Principle:
Principle #3Local quality

AI summary

An exemplary insulator for a flue of a residential oven includes a bendable insulating body having a first end, a second end, and a bending portion. A first cut is disposed between the bending portion and the first end and a second cut is disposed between the bending portion and the second end. The first cut is expandable to form a first opening and the second cut is expandable to form a second opening.
