Solution Overview

Problem

Existing gas cooking appliances face challenges in ensuring proper alignment and secure orientation of the regulating valve with respect to the control panel, which can affect the ease of operation and maintenance.

Innovation Solution

A bracket with a base and arms is secured to the valve body and control panel, featuring complementary housings and pins or protrusions for precise alignment and centring, allowing the valve to be securely attached while enabling easy replacement of external components like the bezel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bracket is used to secure the valve body to the control panel, then the valve orientation and handle alignment are improved, but the device complexity increases due to additional components

Engineering Contradiction:
Improvehandle alignmentVSAvoidbracket structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bracket is divided into a base portion that attaches to the valve body and arm portions that attach to the control panel, allowing independent positioning and alignment of each segment to achieve proper handle alignment while maintaining a relatively simple overall structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket acts as an intermediary component between the valve body and the control panel, providing a mechanical link that ensures proper orientation and alignment of the valve handle with the control panel opening without requiring direct attachment

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the valve is securely attached to the control panel, then the orientation stability is improved, but the ease of repair deteriorates due to difficulty in replacement

Engineering Contradiction:
Improvevalve orientationVSAvoidvalve replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The bracket is designed as a separate, removable component that can be detached from both the valve body and the control panel, allowing the valve to be easily replaced by simply removing the bracket without damaging or modifying the control panel structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket is pre-configured with attachment features that facilitate both secure mounting and easy removal, allowing the valve to be quickly installed or replaced by attaching or detaching the bracket without requiring complex assembly or disassembly procedures

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If complementary housings and pins are used for precise alignment, then the manufacturing precision is improved, but the device complexity increases due to additional alignment features

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment features
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bracket arms feature asymmetric pin configurations and complementary housing shapes that provide precise alignment in specific orientations, ensuring the valve handle aligns correctly with the control panel opening while using simple geometric forms

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The complementary housings and pins are designed to automatically align the bracket arms with the control panel features during assembly, providing self-aligning functionality that ensures precise positioning without requiring additional adjustment mechanisms or complex alignment procedures

Inventive Principle:
Principle #25Self-service
