Soldering Iron Tip Temperature Sensing With Direct Sensor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soldering iron devices suffer from low measurement accuracy due to the temperature sensor detecting the heating core's temperature rather than the tip's temperature, resulting in a temperature difference.
Innovation Solution
A soldering iron device with a measuring element that includes a sensor inserted directly into the tip, mounted on a rod extending away from the tip, and optionally an elastic structure for secure attachment, allowing direct temperature measurement of the tip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is provided in the heating core, then the device structure is simple, but the measurement accuracy is low due to temperature difference between heating core and tip
Solution Approach 1:
The patent introduces a mounting rod as an intermediary component to bridge the gap between the heating core and the tip. The sensor is mounted on the mounting rod, which extends into the tip's measuring cavity, allowing the sensor to directly contact the tip while the mounting rod provides structural support and connection to the heating core assembly.
Solution Approach 2:
The patent transitions the sensor from a one-dimensional position (inside the heating core) to a three-dimensional position (directly in the tip's measuring cavity). This spatial repositioning allows direct temperature measurement at the tip while the mounting rod provides the necessary structural extension.
2Measurement precision
If the sensor is directly inserted into the tip, then the measurement accuracy is high, but the mounting and dismounting operation becomes more complex
Solution Approach 1:
The mounting rod serves as a mediator that simplifies the mounting and dismounting process. The sensor is fixed to the mounting rod, which can be easily inserted into and removed from the tip's measuring cavity. This intermediary structure eliminates the need for direct sensor insertion into the tip, making the operation more convenient.
3Volume of stationary object
If the mounting rod penetrates inside the heating core and is coaxial, then the internal structural space is optimized, but the manufacturing precision requirement increases
Solution Approach 1:
The patent allows the mounting rod to be positioned asymmetrically relative to the heating core, rather than requiring strict coaxial alignment. The rod extends through or near the heating core to reach the tip's measuring cavity, optimizing space utilization while reducing manufacturing precision requirements.

Implementation Method 1
the elastic element may be in a compressed state, one end of the elastic element may abut against the fixture piece, and the other end of the elastic element may abut against an inner wall of the mounting cavity
Implementation Method 2

AI summary
A soldering iron device includes a main body, where an end portion of the main body is provided with a tip, a heating core for heating the tip is provided in the main body, and a measuring element is provided in the main body; and the measuring element includes a mounting rod and a sensor, the sensor is provided on an end portion of the mounting rod, a measuring cavity is formed in the tip, the sensor is inserted into the measuring cavity, and the mounting rod extends toward a direction away from the tip. Compared with the prior art, since the sensor is not provided in the heating core, but is directly inserted into the tip, the present disclosure overcomes the heat transfer distance between the heating core and the tip and directly measures the temperature of the tip, which is highly accurate in measurement and strongly practicable.
