Telescopic Hot Stick Thermal Sensor for Remote Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld non-contact temperature measurement devices are not suitable for situations where the user cannot be in close proximity to the object being measured or where physical proximity poses a risk, as they require direct operation and physical contact or proximity.
Innovation Solution
A non-contact temperature measurement system comprising a head unit with a directional non-contact thermal sensor and a remote unit, allowing wireless transmission of temperature data and featuring a direction pointing protrusion for accurate targeting and a telescopic hot-stick for extended reach, enabling safe and remote temperature measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a handheld non-contact temperature measurement device is used, then temperature measurement capability is provided, but the user cannot measure objects from a distance or when physical proximity poses a risk
Solution Approach 1:
The system is divided into two separate functional units: a head unit containing the thermal sensor and mounted on an extended pole, and a remote unit containing the display and control interface held by the user. This segmentation allows the sensing element to be positioned at a safe distance from hazardous objects while the user interacts with the remote unit from a comfortable position.
Solution Approach 2:
An extended pole or hot-stick serves as an intermediary mechanical linkage between the user and the thermal sensor. This intermediary allows the sensor to reach distant or hazardous targets while keeping the user at a safe distance, effectively mediating the measurement process between the user and the object of interest.
2Object-affected harmful factors
If the user operates the device from a distance, then safety is improved, but targeting precision and measurement accuracy deteriorate
Solution Approach 1:
The head unit features an asymmetric design with a directional protrusion that extends in the direction of the thermal sensor's field of view. This asymmetric feature serves as a visual aiming aid, creating a clear reference point that helps the user align the sensor precisely with the target object, thereby maintaining measurement accuracy despite the extended measurement distance.
Solution Approach 2:
The directional protrusion may incorporate visual indicators such as colored markings or reflective surfaces that enhance visibility and provide clear directional cues. These visual features help the user accurately target the sensor at a distance by creating a conspicuous aiming reference that stands out against the background.
