Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited number of holes in traditional gas stove stopcocks restricts the development of gas stoves by limiting the number of levels, which is a significant technical constraint.
Innovation Solution
A gas flow control device with a drive device, valve body, and piston portion, featuring multiple gas outlets and gathering members, allows for precise control of gas flow to inner and outer-ring fire covers, enabling increased levels of gas stove operation through a motor-driven mechanism that converts rotary motion into linear motion.
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 levels is limited
Solution Approach 1:
The gas flow control device is segmented into multiple functional components: a valve body with multiple gas outlets, a piston portion with selective communication paths, a drive device for axial displacement, and gas gathering members. This segmentation allows each component to perform a specific function, enabling complex multi-level flow control without overwhelming system complexity.
Solution Approach 2:
The invention transitions from the traditional rotary spool mechanism to an axial displacement dimension. The piston portion moves axially within the valve body, creating different communication states between gas outlets and the inner cavity along the axial direction. This dimensional change enables multiple gas outlets to be controlled independently, increasing the number of achievable levels.
2Adaptability or versatility
If multiple gas outlets are added to increase levels, then the adaptability increases, but the volume of the stopcock increases
Solution Approach 1:
Multiple gas outlets are merged into a compact arrangement within the valve body. The gas gathering members consolidate the flow from multiple outlets into unified streams for inner-ring and outer-ring fire covers. This merging approach allows multiple outlets to be controlled independently while maintaining a compact overall volume.
Solution Approach 2:
The piston portion serves multiple functions simultaneously: it controls communication for multiple different gas outlets, regulates flow to different rings, and achieves multiple discrete levels through its axial position. This multi-functionality reduces the need for separate control mechanisms for each outlet, thereby reducing overall volume.
3Adaptability or versatility
If a piston portion with axial displacement is used, then the number of levels increases, but the device complexity increases
Solution Approach 1:
The piston portion acts as an intermediary element between the drive device and the gas outlets. It translates the axial displacement from the drive device into selective communication states for multiple gas outlets. This intermediary approach simplifies the overall control mechanism compared to having separate control devices for each outlet.
Solution Approach 2:
The piston portion is designed to be dynamically positionable along the axial direction, creating different communication configurations as it moves. This dynamic positioning allows a single component to achieve multiple discrete levels by changing its position, rather than requiring multiple static components.
