Solution Overview

Problem

Traditional stove burner pot castings require separate castings for single and dual flame control configurations, which are expensive and inefficient, lacking a solution for a single pot casting that can be machined to provide either two flame rings with simultaneous fuel control or independently controllable dual flame rings.

Innovation Solution

A single pot casting that can be machined in two ways: one configuration for dual flame rings with separate fuel inlets for independent control and another for simultaneous fuel control using a single inlet, featuring lateral and transverse channels with non-intersecting passages to allow for dual or single fuel inlet operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate castings are used for single and dual flame control configurations, then manufacturing precision and reliability are improved, but manufacturing cost and device complexity increase

Engineering Contradiction:
Improveburner configuration reliabilityVSAvoidcasting cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a single pot casting that can serve multiple functions: it can be machined to provide either a single flame ring configuration or dual flame ring configuration with separate fuel inlets. This multi-functional design eliminates the need for separate castings for different burner types, reducing tooling costs while maintaining configuration reliability through precise machining of the universal casting.

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

Solution Approach 2:

The patent applies segmentation by dividing the pot casting into distinct machinable zones that can be configured differently. The casting includes separate regions that can be machined to create either single or dual fuel inlet passages, allowing the same base casting to be segmented into different functional configurations based on machining operations rather than requiring separate castings.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If separate castings are used for single and dual flame control configurations, then functional versatility is improved, but manufacturing cost increases

Engineering Contradiction:
Improveburner configuration flexibilityVSAvoidtooling cost
Core Design Contradiction:

3Ease of manufacture

If a single pot casting is used for both single and dual inlet configurations, then manufacturing cost decreases, but device complexity increases

Engineering Contradiction:
Improvecasting costVSAvoidmachining complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the pot casting into distinct machinable zones that can be configured differently. The casting includes separate regions that can be machined to create either single or dual fuel inlet passages, allowing the same base casting to be segmented into different functional configurations based on machining operations rather than requiring separate castings.

4Productivity

If a single pot casting is used for both single and dual inlet configurations, then manufacturing efficiency is improved, but passage intersection problems worsen

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidpassage non-intersection
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies dimensionality change by designing the fuel passages in three-dimensional space to avoid intersections. The casting geometry is specifically designed so that passages for single inlet and dual inlet configurations can be machined at different depths, angles, or spatial locations within the casting, allowing efficient production while preventing passage intersection through clever 3D routing of the fuel channels.

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

AI summary

A burner has a dual use pot whereby the pot can be machined to provide for single flow control to inner and outer flame rings (directly related to each other) as a single flow configuration or maintained in a dual flow configuration whereby a user can separately control flow to inner and outer flame rings (independently related to one another). A lateral passage is fed from an inlet to feed outer flames while a transverse passage possibly elevationally displaced from the transverse passage for some embodiments can feed the inner ring. The lateral and transverse passages are joined to be in fluid communication through the method taught herein.
