Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited number of holes in traditional gas stove stopcocks restricts the number of levels, hindering the development of gas stoves.
Innovation Solution
A gas flow control device with a drive device, valve body, rotating portion, reposition device, and spool, featuring multiple gas outlets and a replaceable flow adjustment member, allowing for increased levels by rotating the spool to open or close the outlets, and utilizing a motor-driven shaft and cams to manage gas flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional stopcock structure is used, then the device complexity is low, but the number of gas flow levels is limited
Solution Approach 1:
The stopcock body is divided into multiple independent cavities (first cavity, second cavity, third cavity, etc.), each containing its own spool and gas outlet. This segmentation allows each cavity to independently control one or more gas flow levels, enabling the system to provide multiple discrete flow levels while maintaining a modular and manageable structure.
Solution Approach 2:
Multiple spools are arranged concentrically or in nested configurations within the stopcock body, with each spool corresponding to a specific cavity and gas outlet. The nested arrangement allows compact integration of multiple flow control mechanisms within a single device, increasing the number of controllable levels without proportionally increasing external dimensions.
2Adaptability or versatility
If multiple holes are provided on the spool to increase levels, then the number of gas flow levels increases, but the manufacturing precision requirement increases
Solution Approach 1:
Instead of providing multiple holes on a single spool, the invention segments the flow control into multiple separate cavities, each with its own spool and gas outlet. This eliminates the need for precise multi-hole drilling on a single component, as each spool only requires a single hole or simple opening, significantly reducing manufacturing precision requirements while still achieving multiple flow levels.
Solution Approach 2:
The invention transitions from increasing flow levels by adding multiple holes in the same plane (2D approach) to creating multiple levels through additional spatial dimensions by adding more cavities and spools in a nested or concentric arrangement (3D approach). This dimensional transition allows for multiple flow levels without the compounding precision requirements of multi-hole drilling.
3Adaptability or versatility
If a compact stopcock structure is used, then the volume is small, but the number of levels is limited
Solution Approach 1:
Multiple spools and cavities are arranged in a nested or concentric configuration where smaller components are positioned within or around larger ones. This nested arrangement maximizes the utilization of internal space, allowing multiple flow control levels to be integrated within a compact overall volume, thereby increasing the number of levels without a proportional increase in device size.
Solution Approach 2:
The invention utilizes three-dimensional spatial arrangement by creating multiple cavities and spools in different spatial positions (concentric or nested), rather than simply extending the device in one direction. This 3D utilization of space allows for increased functional complexity and number of levels while maintaining a compact external footprint.

AI summary
The present invention provides a novel gas flow control device for a gas stove and a gas stove. A gas flow control device for a gas stove provided by the present invention includes a drive device (12), a valve body (1), a rotating portion (2), a reposition device (3), and a spool (4, 5); the valve body includes an inner cavity (6), a gas inlet (7), and a gas outlet, and the gas inlet and the gas outlet are separately in communication with the inner cavity; the spool is disposed in the inner cavity; the drive device is used to drive the rotating portion to rotate; when the rotating portion is located in a first rotation position, the spool is pushed by the rotating portion to close the gas outlet; and when the rotating portion is located in a second rotation position, the spool, under the action of the reposition device, opens the gas outlet. By adopting the technical solution, the number of levels of the gas stove can be easily increased
