Forehead Thermometer Side Indicator Light for Rapid Temperature Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forehead thermometers require users to retrieve the device and view an LCD screen to determine body temperature, leading to reduced detection efficiency, especially for taller individuals or when measuring multiple people.
Innovation Solution
A forehead thermometer with an indicator light that displays different colors based on detected temperatures, allowing users to assess body temperature without removing the device, featuring a transparent light guide body and a backlight board that simplifies the circuit structure and reduces costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users view the LCD screen to determine body temperature, then the temperature measurement is accurate, but the detection time increases and detection efficiency decreases
Solution Approach 1:
The patent divides the information display function into two parts: the LCD screen provides detailed temperature information for accurate measurement, while the indicator light provides immediate visual feedback for quick assessment. This segmentation allows users to obtain both precise measurement and rapid results depending on their needs.
Solution Approach 2:
The indicator light acts as an intermediary element between the temperature measurement system and the user. It translates the measured temperature into immediate visual color cues (green for normal, yellow for elevated, red for high fever), allowing users to quickly assess results without needing to read the LCD screen.
2Measurement precision
If users view the LCD screen to determine body temperature, then the temperature measurement is accurate, but detection efficiency decreases especially for taller individuals or when measuring multiple people
Solution Approach 1:
The indicator light serves as an intermediary that provides immediate visual feedback, eliminating the need for users to retrieve and read the LCD screen. This is particularly beneficial for taller individuals who may have difficulty reaching the display, and for high-volume screening where rapid assessment is crucial.
Solution Approach 2:
The patent provides more than one way to obtain measurement results: the indicator light offers sufficient information for most users to quickly determine if a reading is normal or requires attention, while the LCD screen provides complete detailed information for those who need it. This partial action approach speeds up routine screenings.
3Productivity
If an indicator light is added to display different colors according to temperature, then detection efficiency improves, but device complexity increases
Solution Approach 1:
The indicator light system serves multiple functions: it provides immediate temperature assessment, eliminates the need for users to read the LCD screen, and works for users of all heights. The backlight board with different colored LEDs (green, yellow, red) creates a multi-functional visual indication system that enhances the basic temperature measurement capability.
Solution Approach 2:
Instead of using a complex additional display system, the patent uses a simplified approach by copying the temperature information into visual color form through the indicator light. This creates a parallel, simpler information channel that conveys the essential temperature status without requiring complex additional components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly improves detection efficiency by enabling users to quickly judge normal, low fever, or high fever states by observing the color of the indicator light from the side, eliminating the need to view the LCD screen.
Implementation Method 1
a body temperature detection probe, fixedly disposed at a front end of the housing
Implementation Method 2
a backlight board that can light up in different colors according to different temperatures detected by the body temperature detection probe
Implementation Method 3
a light guide plate that can guide the light emitted from the backlight board to the indicator light

AI summary
In view of the drawback that the detection efficiency will be significantly reduced since the result is viewed after measurement in forehead thermometers in the prior art, the present disclosure provides a forehead thermometer that displays different colors according to detected temperatures and a control circuit thereof, which belong to the technical field of forehead thermometers. The forehead thermometer includes a forehead thermometer body, the forehead thermometer body being provided with an indicator light at a side, which can light up in different colors according to different detected temperatures. The forehead thermometer is provided at a side with the indicator light which can light up in different colors according to detected temperatures, so that whether the body temperature of the detected person is normal can be judged by simply viewing the different colors of the indicator light at the side of the forehead thermometer, which can significantly improve the detection efficiency.
