Solution Overview
Problem
The assembly process of existing heating appliances is complex and inefficient due to the numerous components and assembly steps required for the temperature sensor, leading to bottlenecks and reduced production efficiency.
Innovation Solution
A simplified assembly process for a heating appliance is achieved by incorporating a movable probe with a stop-limiting portion and an elastic support, which allows for pre-fixation between the probe, heating part, and elastic support, reducing the number of components and assembly steps, and utilizing a modular structure for the temperature sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple components (limiting clamp spring, sleeve, thermistor module, housing) are used to ensure temperature sensor functionality, then measurement precision and reliability are improved, but device complexity and assembly process complexity increase
Solution Approach 1:
The patent combines the limiting clamp spring, sleeve, and thermistor module into an integrated temperature sensor assembly. The limiting clamp spring is assembled with the housing and abuts against the coil disc to limit the housing upwardly, while the thermistor module is mounted in the housing with the sleeve providing support. This merging reduces the number of separate assembly steps and components while maintaining the temperature measurement accuracy through the integrated structure.
Solution Approach 2:
The housing serves multiple functions: it provides structural support for the thermistor module, acts as a limiting element through the limiting clamp spring, and interfaces with the coil disc. The limiting clamp spring simultaneously limits the housing upwardly and provides elastic support. This multi-functionality reduces the need for separate components, simplifying the assembly process while maintaining measurement precision.
2Reliability
If the housing is passed through the through hole of the coil disc and multiple components are assembled, then the temperature sensor can be properly positioned and limited, but the assembly process becomes complicated and involves many steps
Solution Approach 1:
The limiting clamp spring is pre-assembled with the housing before the housing is installed through the coil disc. The spring is configured to abut against the coil disc and limit the housing upwardly, ensuring proper positioning is established in advance. This preliminary assembly of the limiting mechanism with the housing reduces the number of steps required during final installation and improves position stability.
3Measurement precision
If the limiting clamp spring is assembled with the housing to limit the housing upwardly and the thermistor module is limited downwardly, then measurement precision and reliability are improved, but the assembly process involves bottleneck processes and reduces productivity
Solution Approach 1:
The patent merges the limiting clamp spring assembly with the housing assembly into a single integrated unit. The spring is assembled with the housing and configured to limit the housing upwardly, while the thermistor module is mounted in the housing with the sleeve providing support and limiting the module downwardly. This merging allows the entire temperature sensor assembly to be installed as one unit through the coil disc, eliminating bottleneck processes and improving assembly efficiency while maintaining measurement precision through the integrated limiting mechanisms.
