Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas supply valves for cooking appliances are complex to use and require multiple parts to regulate gas flow, making it difficult for users to achieve consistent gas flow rates for different types of gas, such as natural gas and petroleum gas, without stable and repeatable position associations.
Innovation Solution
A gas supply valve design featuring a regulating cone and a regulator member that can rotate between positions to control gas flow, allowing adaptation to different types of gas with a single gesture, ensuring consistent heating power by adjusting channel configurations, and incorporating a movable part with notches to associate positions with specific gas flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a regulating cone is rotated to regulate gas flow between minimum and maximum positions, then gas flow regulation is achieved, but the positions of the adjustment knob and operating mechanism are not stable and repeatable, making it difficult for users to know which gas flow rate is associated with each position
Solution Approach 1:
The patent implements a feedback mechanism through audible clicks generated during rotation of the regulating cone. These clicks provide real-time feedback to the user about the current position of the cone, enabling precise control and repeatable positioning. The click mechanism is integrated into the operating mechanism, allowing users to hear distinct auditory signals at specific angular positions, thereby knowing exactly which gas flow rate is associated with each position without visual aids.
2Adaptability or versatility
If multiple parts are used to regulate gas flow and adapt to different gas types, then adaptability to different gas types is improved, but the device complexity increases and requires multiple tools for calibration
Solution Approach 1:
The patent merges the functions of gas flow regulation and gas type adaptation into a single integrated mechanism. The regulating cone itself is designed with different geometric configurations (different angles and dimensions) that can be selectively positioned to accommodate different gas types. This eliminates the need for separate calibration devices, multiple regulating components, or tool-based adjustment mechanisms. The single regulating cone performs both flow control and gas type adaptation functions.
Solution Approach 2:
The regulating cone is designed as a universal component that can handle multiple gas types (natural gas, petroleum gas, LPG) through its geometric design. Different angular positions of the same cone correspond to different gas flow rates and different gas type configurations. This multi-functional design allows one component to replace what would traditionally require multiple specialized parts, simplifying the overall device structure while maintaining adaptability.
3Manufacturing precision
If a bypass device with a needle is used to calibrate reduced flow, then calibration capability is achieved, but the valve requires tools such as a screwdriver for rotation, making it difficult to use
Solution Approach 1:
The patent implements self-service calibration by integrating the calibration function directly into the user-operated regulating mechanism. The same rotating motion that users perform to control gas flow also performs the calibration function. There is no separate calibration device requiring external tools. The regulating cone's rotation naturally adjusts the flow characteristics, and the system provides self-contained adjustment capabilities through its geometric design, eliminating the need for tool-assisted calibration.
