Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plug valve is used to control gas flow, then the gas flow control function is achieved, but the processing becomes inconvenient and cost increases
Solution Approach 1:
The valve core is segmented into multiple valve cores with different shapes (cylindrical, tapered, conical) arranged in sequence. Each valve core controls a specific portion of the gas flow, allowing independent optimization of each segment's function while simplifying the overall structure and processing requirements.
Solution Approach 2:
Different portions of the valve core are given different local qualities through varying cross-sectional shapes (cylindrical sections for linear control, tapered sections for progressive control, conical sections for rapid control). This allows each local region to perform its specific control function optimally while maintaining overall structural simplicity.
2Manufacturing precision
If a plug valve is used to control gas flow, then the gas flow control function is achieved, but the gas flow change becomes uneven across different control grades
Solution Approach 1:
The valve core is divided into multiple segments with different cross-sectional shapes (cylindrical, tapered, conical) that correspond to different control grades. Each segment provides a specific flow control characteristic, enabling even distribution of gas flow across all control grades while keeping the overall valve structure relatively simple.
Solution Approach 2:
The cross-sectional parameters of the valve core are changed along its length, transitioning from cylindrical to tapered to conical sections. This gradual parameter change creates a progressive control effect where each section contributes differently to the overall flow control, achieving even gas flow distribution across control grades.
3Manufacturing precision
If multiple valve cores with different shapes are used, then even gas flow control across different grades is achieved, but the device complexity increases
Solution Approach 1:
Multiple valve cores with different functions (cylindrical, tapered, conical) are merged into a single integrated valve core structure. This unified design allows all control functions to be achieved through one component rather than multiple separate components, reducing assembly complexity while maintaining the ability to provide even gas flow control across different grades.

AI summary
A gas regulating valve used in a gas stove includes a valve body, and a rotating disk in plane contact with a surface of an inner cavity of the valve body and capable of rotating relative to the surface of the inner cavity of the valve body. The valve body is provided with a gas inlet and a gas outlet, and a contact surface of the valve body and that of the rotating disk are fitted in a sealed manner. The rotating disk has a connection channel capable of selectively connecting or disconnecting the gas outlet on the valve body and the inner cavity of the valve body or changing a communication degree therebetween when the rotating disk rotates. The present invention further provides an electrically controlled gas regulating valve used in a gas stove, and a gas stove including the gas regulating valve or the electrically controlled gas regulating valve. The technical solutions of the present invention solve the problem that a plug valve used in an existing gas stove is inconvenient to process and has a high cost.
