Universal Furnace Controller Harness Connector Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furnace controllers for gas-powered systems lack compatibility with different furnace systems due to varying wiring harness pin configurations, leading to excess costs and increased complexity in installation, as multiple adapters are often required for each manufacturer's system.
Innovation Solution
A furnace controller with a circuit board and multiple harness connectors, each with unique pin configurations, where at least one pin connector from each connector is connected in parallel, allowing for compatibility with various wiring harnesses without the need for additional adapters, by remapping pin connections based on the specific wiring configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wiring harness adapters are provided to improve compatibility with different furnace systems, then adaptability is improved, but device complexity and installation complexity increase
Solution Approach 1:
The controller is designed with multiple harness connectors (first, second, third connectors) integrated directly into the circuit board, each capable of connecting to different wiring harness pin configurations. This multi-functional design eliminates the need for separate adapters while maintaining compatibility with various furnace system manufacturers, directly resolving the contradiction by providing universal compatibility without increasing device complexity.
Solution Approach 2:
Multiple harness connectors that were previously separate adapter components are merged and integrated directly onto the controller's circuit board. This consolidation reduces the total number of parts and simplifies the overall system while maintaining the ability to connect to different wiring harness configurations, thereby improving compatibility without increasing complexity.
2Adaptability or versatility
If multiple wiring harness adapters are provided to improve compatibility with different furnace systems, then adaptability is improved, but loss of substance increases due to excess costs and waste
Solution Approach 1:
The controller incorporates multiple harness connectors with different pin configurations directly into the circuit board, making the controller itself universal and compatible with various furnace systems. This eliminates the need to manufacture, package, and ship multiple separate adapter components, reducing material waste and excess costs while maintaining full compatibility.
Solution Approach 2:
The functionality previously extracted into separate adapter components is taken back and integrated directly into the controller's circuit board. This extraction of the adapter function from separate components eliminates the waste associated with producing and distributing multiple unused adapters, while still providing the necessary compatibility features.
3Adaptability or versatility
If wiring harness adapters are used to connect furnace controller to different systems, then adaptability is improved, but ease of operation deteriorates due to increased installation complexity
Solution Approach 1:
Multiple harness connectors are merged and integrated directly onto the controller's circuit board in fixed positions. This eliminates the need for technicians to identify, select, and install separate adapter components, significantly simplifying the installation process while maintaining compatibility with different wiring harness configurations.
Solution Approach 2:
The controller is designed as a universal unit with multiple built-in connectors that can accommodate different wiring harness pin configurations. This eliminates the operational complexity of matching and installing separate adapters, making installation straightforward while ensuring broad compatibility across different furnace system manufacturers.
