Modular Thermal Fuse Assembly for Accurate Appliance Heat Cutoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal assemblies in appliances require separate replacement of temperature sensing devices and thermal fuses, leading to potential malfunctions and increased service calls when the temperature sensing device is not replaced concurrently with the thermal fuse.
Innovation Solution
A modular thermal assembly that integrates a temperature sensing device and a thermal fuse onto a common housing, allowing for attachment and detachment as a single unit from the appliance, ensuring accurate heat detection and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the thermal fuse and temperature sensing device are replaced separately, then the replacement process becomes complex and time-consuming, but the modular integrated design increases device complexity
Solution Approach 1:
The patent combines the thermal fuse and temperature sensing device into a single modular assembly that is pre-mounted on a common housing. This integration allows both components to be replaced together as one unit, eliminating the complexity of separate replacements and ensuring that both components are simultaneously updated to working condition.
2Ease of manufacture
If only the thermal fuse is replaced without the temperature sensing device, then the immediate repair cost is lower, but the appliance may malfunction again requiring repeat service calls
Solution Approach 1:
The modular assembly is designed to be replaced as a complete unit, performing the preliminary action of replacing both the thermal fuse and temperature sensing device simultaneously. This prevents the scenario where a newly replaced thermal fuse immediately fails again due to a malfunctioning temperature sensing device, thereby eliminating repeat service calls.
3Ease of manufacture
If the thermal fuse and temperature sensing device are mounted at different locations, then the housing design is simpler, but the thermal fuse detection accuracy decreases
Solution Approach 1:
The patent positions both the thermal fuse and temperature sensing device at the same local position on the housing, specifically near the heat source. This localized arrangement ensures that both components experience the same thermal conditions, maximizing detection accuracy while the common housing design maintains manufacturing simplicity.

Function Achieved in This Case
This integration improves thermal fuse detection accuracy, reduces repeat service calls, and lowers costs for manufacturers and service providers by simplifying part management and installation.
Implementation Method 1
a thermal fuse can also be used to shut down the heater before the heat produced by the heater reaches a dangerous level
Implementation Method 2
A temperature sensing device can be used to regulate the amount of heat produced by the heater

AI summary
An appliance assembly includes an appliance and a thermal assembly. The thermal assembly includes a housing attached to the appliance, a temperature sensing device carried by the housing and electrically coupled with the appliance, and a thermal fuse carried by the housing and electrically coupled with the appliance, the thermal assembly being a modular assembly and thereby configured for being, as a single unit, attached to and detached from the appliance.
