Universal Spark Ignition Controller for IP and DSI Gas Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spark ignition modules for gas-powered appliances are typically configured for either direct spark ignition (DSI) or intermittent pilot (IP) systems, requiring separate modules for each type and making it difficult to configure the module for different ignition systems.
Innovation Solution
A controller with a circuit board, multiple connectors, and a processor that can be programmed to control both IP and DSI systems, allowing users to select the appropriate configuration through user interfaces or mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate spark ignition modules are used for IP and DSI systems, then each module can be optimized for its specific function, but the device complexity and inventory requirements increase
Solution Approach 1:
The controller is designed with universal functionality to support both intermittent pilot (IP) and direct spark ignition (DSI) systems through software configuration. The processor can be programmed via dipswitches, buttons, or mobile devices to control different ignition sequences, gas valve operations, and component timing for either IP or DSI modes, eliminating the need for separate hardware modules for each system type
2Adaptability or versatility
If a single controller supports both IP and DSI systems, then the adaptability and inventory efficiency improve, but the control logic complexity increases
Solution Approach 1:
The controller employs dynamic configuration capabilities where the control logic adapts based on user-selected ignition mode. The system can switch between IP and DSI operational sequences through programmable settings, allowing the same hardware to dynamically reconfigure its control strategy, timing parameters, and component activation patterns depending on the selected ignition system type
Solution Approach 2:
The controller utilizes configurable parameters such as dipswitch settings, button combinations, or mobile device inputs to change operational characteristics. These parameter changes enable the same controller to implement different ignition sequences, gas valve control timing, and component coordination patterns appropriate for either IP or DSI systems without requiring physical reconfiguration

AI summary
A controller for use in a gas appliance system includes a circuit board, a plurality of connectors and a processor mounted on the circuit board. The processor controls operation of the gas appliance using, in part, at least one connector of the plurality of connectors and control settings for an intermittent pilot (IP) system in response to a user selection to configure the controller to control an IP system, and controls operation of the gas appliance using, in part, at least one connector of the plurality of connectors and control settings for a direct spark ignition (DSI) system in response to a user selection to configure the controller to control a DSI system.
