Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic gas valves in gas cooking appliances require separate main and secondary fluid channels, leading to increased complexity, size, and cost due to the need for two gas conduits, which complicates integration with gas regulating valves.
Innovation Solution
An electromagnetic gas valve design that integrates a secondary fluid channel within the closure member, allowing a single gas conduit, which simplifies the structure and reduces size by eliminating the need for separate channels, enabling direct coupling with gas regulating valves and reducing overall appliance complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate main and secondary fluid channels are used, then the electromagnetic gas valve can provide both maximum and minimum gas flow, but the device complexity and size increase due to requiring two gas conduits
Solution Approach 1:
The patent merges the secondary fluid channel directly into the closure member (needle) itself, rather than having it as a separate component. The needle contains an internal passage that serves as the secondary fluid channel, allowing minimum gas flow when the valve is closed. This integration eliminates the need for separate parallel channels and reduces overall device complexity while maintaining both maximum and minimum flow capabilities.
Solution Approach 2:
The secondary fluid channel is nested within the closure member structure. The needle (closure member) contains an internal passage that forms the secondary channel, effectively placing one functional element inside another. This nesting approach allows the minimum flow path to be accommodated within the existing closure member geometry without adding external complexity.
2Adaptability or versatility
If separate main and secondary fluid channels are used, then the electromagnetic gas valve can provide both maximum and minimum gas flow, but the volume and space requirements increase
Solution Approach 1:
By combining the secondary fluid channel functionality into the closure member itself, the patent eliminates the need for separate parallel channel structures. The integrated design uses the existing valve body and closure member geometry to accommodate both flow paths, significantly reducing the overall volume required compared to separate channel configurations.
Solution Approach 2:
The nested configuration of the secondary channel within the closure member allows efficient space utilization. The internal passage of the needle serves dual purposes: as part of the closure mechanism and as the secondary flow path, maximizing functional density within minimal volume.
3Adaptability or versatility
If separate main and secondary fluid channels are used, then the electromagnetic gas valve can provide both maximum and minimum gas flow, but the manufacturing cost increases
Solution Approach 1:
The integration of the secondary fluid channel into the closure member reduces the total number of parts that need to be manufactured and assembled. Instead of producing separate main and secondary channel components, the design consolidates these functions into fewer elements, simplifying manufacturing processes and reducing assembly steps, thereby lowering production costs.
Solution Approach 2:
The closure member is designed to serve multiple functions: it acts as the primary closure element for the main fluid channel and simultaneously contains the secondary fluid channel for minimum flow. This multi-functionality reduces the number of specialized components needed, simplifying manufacturing and reducing overall system cost.
4Adaptability or versatility
If separate main and secondary fluid channels are used, then the electromagnetic gas valve can provide both maximum and minimum gas flow, but the integration with gas regulating valve becomes more complex
Solution Approach 1:
By merging the secondary channel into the closure member, the patent creates a more compact and integrated valve structure that requires fewer external connections and components when integrating with a gas regulating valve. The simplified architecture with fewer separate channels makes the coupling and installation process more straightforward and less prone to leakage issues.

Data Source
AI summary
Electromagnetic gas valve with a gas inlet, a gas outlet, and a closure member that is displaceable between an opening position and a closing position. A maximum flow is supplied through the gas outlet with the closure member in the open position and a minimum flow being supplied with the closure member in the closed position. The valve includes a main fluid channel with a closure hole through which the maximum flow is supplied to the gas outlet. The closure member includes a secondary fluid channel calibrated for the minimum flow to pass therethrough, such that the closure member in the closed position covers the closure hole and allows the passage of gas through the secondary fluid channel.
