Solution Overview

Problem

Existing gas-fueled cooktops face challenges in achieving uniform heating when using a griddle, as they often lack a one-to-one valve-to-burner ratio and require additional components for gas supply, leading to complex connections and non-uniform heating.

Innovation Solution

A tube assembly with an orifice holder that integrates multiple gas passages and tubes, allowing for independent control of burners in normal mode and simultaneous operation in griddle mode without additional components, reducing connections and enhancing uniform heating by channeling gas through multiple valves to multiple burners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a one-to-one valve-to-burner ratio is used, then each burner can be controlled independently, but it becomes difficult to achieve uniform heating when using a griddle

Engineering Contradiction:
ImproveIndependent burner controlVSAvoidUniform heating
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The orifice holder is designed with multiple tube passages (first tube passage, second tube passage, etc.) that allow a single orifice holder to receive gas from multiple different valves and distribute it to multiple burners. This multi-functional design enables the system to switch between independent burner control mode and griddle mode (where multiple burners are controlled as a unit), resolving the contradiction between independent control capability and uniform heating capability.

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

2Adaptability or versatility

If multiple separate components are used for gas supply connections, then gas distribution flexibility is improved, but device complexity increases

Engineering Contradiction:
ImproveGas supply flexibilityVSAvoidNumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple tube passages and their corresponding tube openings are integrated into a single orifice holder body. Instead of using separate components for each gas supply connection, the invention combines multiple gas distribution functions into one unified orifice holder structure, reducing the number of parts while maintaining the flexibility to connect to multiple valves and burners.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The orifice holder serves multiple functions simultaneously: it acts as a gas distribution manifold with multiple tube passages for different gas supplies, an orifice plate holder, and a mounting component for the burner. This multi-functionality eliminates the need for separate components, reducing overall device complexity while maintaining gas supply flexibility.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables uniform heating of multiple burners by allowing simultaneous control through a common valve, reducing component complexity and connections, and ensuring even heat distribution during griddle mode operation.

Implementation Method 1

The orifice holder includes a body, an orifice passage defined in the body, a first tube passage defined in the body, and a second tube passage defined in the body. The orifice passage, the first tube passage, and the second tube passage are in flow communication within the body.
