Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas burning devices require manual operation and visual observation to confirm proper configuration with different fuel types, and they often need separate systems or complex gas distribution valves due to the large thermal value differences between fuels.
Innovation Solution
A fuel burning system that automatically detects the fuel type using thermocouples and a printed circuit board, allowing for seamless operation with either fuel without manual intervention, and includes a thermoelectric generating system to power the system and control valves, eliminating the need for external power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate independent systems or complex gas distribution valves are used to handle different fuel types, then the system can utilize multiple fuel types, but the device complexity increases
Solution Approach 1:
The patent implements a single integrated gas distribution valve that can handle both propane and natural gas flows, replacing the need for separate independent systems. The valve is designed with multiple positions (off, propane, pilot, natural gas, service) to universally manage different fuel types through one component, thereby reducing overall system complexity while maintaining multi-fuel capability
Solution Approach 2:
The patent combines the functions of multiple fuel management components into a single integrated valve assembly and control system. The electronic control system merges fuel type detection, valve control, and safety monitoring into one unified system that automatically manages both propane and natural gas operations, eliminating the need for separate manual control mechanisms
2Device complexity
If manual operation is required for ignition and fuel selection, then the system can be operated with simple components, but the ease of operation decreases
Solution Approach 1:
The patent implements an automatic ignition system that eliminates manual intervention. The electronic control system automatically detects the connected fuel type (propane or natural gas) and initiates the appropriate ignition sequence without user input. The system self-manages the entire ignition process, including activating the correct burner elements and adjusting gas flow, thereby significantly improving ease of operation
Solution Approach 2:
The patent incorporates sensors and control logic that provide real-time feedback on fuel type detection and ignition status. The system monitors whether propane or natural gas is connected and automatically adjusts its operation accordingly, ensuring proper fuel management without requiring manual observation or adjustment by the user
3Device complexity
If visual observation is required to confirm proper flame configuration, then the system can use simple ignition components, but the ease of operation and safety decrease
Solution Approach 1:
The patent incorporates electronic sensors and control logic that automatically detect and verify proper fuel configuration and flame establishment. The system provides electronic feedback to confirm correct operation, eliminating the need for visual observation. This automated verification enhances both safety and ease of operation by ensuring proper fuel-matcher pairing without user intervention
4Reliability
If external power sources are required to operate the control system and ignition, then the system can function reliably, but the device complexity and power dependency increase
Solution Approach 1:
The patent implements a self-powered system where the gas burning appliance generates its own electricity through thermoelectric generators or other energy conversion mechanisms. The generated power is used to operate the electronic control system, ignition elements, and gas distribution valve, eliminating external power dependencies. This self-sustaining approach maintains reliability while reducing overall system complexity
