Universal Flame Sensor Kit for Multi-OEM Furnace Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of original equipment manufacturer (OEM) gas furnace flame sensors in various configurations complicates maintenance for field service technicians and distributors, leading to unnecessary trips, wasted time and money, and potential missed service calls due to the need for multiple stock keeping units (SKUs) and lack of parts.
Innovation Solution
A universal flame sensor kit that includes multiple screw-in flame sense rods, an adjustable flame sensor body, wiring adapters, and mounting brackets, allowing technicians to configure a replacement part for multiple OEM configurations, reducing the need for multiple SKUs and facilitating easy field replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple OEM-specific flame sensor configurations are maintained in stock, then compatibility with different furnace models is improved, but inventory complexity and storage requirements increase
Solution Approach 1:
The patent creates a universal flame sensor assembly that can replace multiple OEM-specific configurations through standardized mounting brackets, adjustable positioning mechanisms, and interchangeable flame sense rods. This single universal design serves the function of multiple specialized parts, allowing technicians to maintain one inventory item instead of numerous OEM-specific SKUs while still achieving compatibility across different furnace models.
Solution Approach 2:
The universal flame sensor assembly is divided into separable components including mounting brackets, positioning mechanisms, and flame sense rods that can be independently selected and configured. This segmentation allows the same basic assembly to be adapted to different furnace types by swapping or adjusting individual components rather than maintaining entirely different assembled units for each OEM configuration.
2Reliability
If technicians carry multiple flame sensor SKUs in their service vehicles, then part availability for different OEM configurations is improved, but vehicle space and weight capacity are consumed
Solution Approach 1:
By implementing a universal flame sensor assembly that can serve multiple OEM configurations, technicians only need to carry one type of sensor in their service vehicles instead of multiple OEM-specific SKUs. This maintains part availability across different furnace models while dramatically reducing the weight and space required in the service vehicle inventory.
3Manufacturing precision
If technicians make multiple trips to distributors to obtain correct flame sensor parts, then part accuracy is improved, but service time and productivity are reduced
Solution Approach 1:
The universal flame sensor assembly is designed with pre-configured mounting brackets, positioning mechanisms, and interchangeable components that allow technicians to perform the correct installation in a single service call. The preliminary design work of creating a universal fit-all solution eliminates the need for follow-up trips to distributors, as the single universal part can accommodate any OEM configuration without requiring additional procurement trips.
4Device complexity
If a single universal flame sensor design is used, then inventory simplicity is improved, but adaptability to specific OEM configurations may be compromised
Solution Approach 1:
The universal flame sensor assembly incorporates adjustable and reconfigurable elements such as adjustable positioning brackets, movable mounting components, and interchangeable flame sense rods. These dynamic features allow the same basic assembly to be adapted to specific OEM configurations on-demand during installation, maintaining inventory simplicity while preserving the ability to fit various furnace types through field-adjustable mechanisms rather than requiring pre-configured specialized parts.

AI summary
A flame sensor assembly includes a flame sense rod and a flame sensor body. The flame sense rod includes a flame sensor end and a coupling end opposite the flame sensor. The flame sensor body defines a receptacle for receiving the coupling end of the flame sense rod, and includes an adjustable positioning bracket. The assembly also includes a wiring adapter for connecting the flame sensor body with a flame sense signal connector, and a mounting bracket adapted to mount the flame sensor body to a heating device with the flame sensor end of the flame sense rod positioned adjacent a flame of the heating device. Methods of replacing a flame sensor assembly for a heating device are also disclosed.
