Solution Overview
Problem
Existing gas valve technologies for electronically controlled gas appliances face challenges with space requirements and production costs, particularly when dealing with different types of gas and burners with varying nominal outputs, and require precise and reproducible gas flow control with a shut-off valve.
Innovation Solution
A rotor disk valve with a stamped thin sheet metal rotor disk, driven by a pinion with a selectable transmission ratio, and a solenoid shut-off valve, allowing for precise and reproducible gas flow control with a compact design, using a common gas supply line and distribution line to minimize space and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rotor valve with a hollow cone body and bypass channel is used, then gas flow control is achieved, but space requirement and manufacturing complexity increase
Solution Approach 1:
The patent replaces the complex mechanical bypass channel system with an electronically controlled valve system. The electronic valve uses an electromagnetic actuator to control gas flow through a simple opening, eliminating the need for complex mechanical bypass channels and reducing both manufacturing complexity and space requirements.
Solution Approach 2:
The patent integrates multiple functions into a single valve unit: the electronic valve serves both as a flow control mechanism and a shut-off mechanism. The sensor system provides both flow detection and control feedback, eliminating the need for separate bypass channels and reducing overall system complexity.
2Manufacturing precision
If mechanically controlled gas valves are used, then gas flow control is achieved, but precision and control functions are limited
Solution Approach 1:
The patent replaces mechanical control mechanisms with an electronic control system. The electronic valve receives electrical signals to precisely control gas flow, while sensors provide feedback for automated regulation. This substitution enables higher precision flow control and more sophisticated control functions compared to purely mechanical systems.
Solution Approach 2:
The patent incorporates sensor systems that detect gas flow parameters and provide feedback to the electronic control unit. This feedback mechanism enables precise, reproducible adjustment of gas flow by continuously monitoring and adjusting the valve position based on actual flow conditions, achieving high manufacturing precision.
3Adaptability or versatility
If multiple valve units with separate gas lines are used, then gas flow control for multiple burners is achieved, but space requirement increases
Solution Approach 1:
The patent merges multiple valve functions into a single integrated valve device. The electronic valve system with common sensor and control unit can control gas flow to multiple burners through a unified control mechanism, eliminating the need for completely separate valve units and reducing the space required in the gas hob.
Solution Approach 2:
The patent designs the valve unit to perform multiple functions: a single electronic valve system can control gas flow to multiple burners, provide individual shut-off for each burner, and enable various control modes (flame failure detection, electronic ignition, different flame levels). This multi-functionality reduces the number of separate components needed.
