Remote Controller Temperature Sensor Mounting for Accurate Air Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning remote controllers face challenges in accurately measuring atmospheric temperature due to the temperature sensor's limited insertion depth, leading to inaccurate positioning and decreased measurement accuracy, and manual adjustments are necessary to correct the sensor's position, which complicates assembly and can result in variability and reduced accuracy.
Innovation Solution
The air-conditioning remote controller design includes a temperature sensor with a covered wire inserted through a hole in the printed board and engaged with a cut in a partition portion, allowing the temperature detection portion to be stably fixed near the inner case surface without manual adjustment, reducing variability and avoiding contact with the upper case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the intermediate portion of the temperature sensor is inserted deeper into the cut to bring the temperature detection portion closer to the atmosphere, then the measurement accuracy is improved, but the temperature detection portion comes into contact with the case and is influenced by the case temperature
Solution Approach 1:
The partition portion is divided into an upper partition portion and a lower partition portion with a gap between them, creating a segmented structure that allows the temperature detection portion to be positioned in the gap where it can access atmospheric temperature without contacting the case walls
Solution Approach 2:
The temperature sensor is positioned to extend in the thickness direction of the case, utilizing the vertical dimension to place the detection portion in the gap between partition portions rather than having it contact the horizontal case surfaces
2Measurement precision
If the intermediate portion of the temperature sensor is pressed into the cut during manufacture to increase insertion depth, then the temperature detection portion is brought closer to the atmosphere, but additional manual operations are required and the sensor may bend backward
Solution Approach 1:
The lower partition portion is pre-formed with a protrusion that engages with the temperature sensor's intermediate portion, and the upper partition portion is pre-formed with a corresponding cut, so that when assembled, the sensor is automatically positioned and fixed at the correct depth without requiring manual pressing operations
Solution Approach 2:
The partition portion structure itself provides the fixing function through the protrusion-cut engagement mechanism, eliminating the need for external manual pressing tools or operations to secure the temperature sensor in place
3Measurement precision
If the temperature sensor is fixed with high insertion depth to improve measurement accuracy, then the detection portion is closer to the atmosphere, but the position variability increases due to manual adjustment requirements
Solution Approach 1:
The protrusion of the lower partition portion acts as an intermediary fixing element that mechanically engages with the temperature sensor, providing a precise and consistent stopping point that eliminates position variability caused by manual adjustment differences
Solution Approach 2:
The cut in the upper partition portion and protrusion in the lower partition portion are pre-configured to match the optimal insertion depth, so that during assembly the sensor naturally reaches the correct position without requiring operator judgment or adjustment, ensuring consistent positioning across all units
