Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature measuring devices, such as ear and forehead thermometers, are inconvenient and hygienic concerns exist with ear thermometers, while forehead thermometers are often inaccurate due to environmental sensitivity and limited functionality, lacking the ability to measure both ear and forehead temperatures simultaneously.
Innovation Solution
A temperature detecting device equipped with a reflecting shell featuring a hollow joint unit, guide unit, and receiving unit, where heat radiation is reflected by corresponding surfaces to focus and transmit infrared radiation to a detecting part, enabling accurate measurement of both ear and forehead temperatures with improved hygiene and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ear thermometer is used to measure temperature, then measurement accuracy is improved, but hygiene concerns arise due to insertion into ear
Solution Approach 1:
The patent combines the ear thermometer and forehead thermometer into a single integrated device. The temperature detection device includes both an ear detection module and a forehead detection module with a reflecting shell, allowing users to have one device that performs both functions, eliminating the need to choose between hygiene and accuracy
Solution Approach 2:
The reflecting shell acts as an intermediary component that enables the ear thermometer functionality to be integrated into the forehead thermometer device. The reflecting shell focuses infrared radiation from the ear canal onto the detection sensor, allowing accurate ear temperature measurement without direct insertion of the entire device into the ear
2Object-affected harmful factors
If forehead thermometer is used for non-contact measurement, then hygiene is improved, but measurement accuracy deteriorates due to environmental sensitivity and limited detecting distance
Solution Approach 1:
The reflecting shell serves as an optical intermediary that collects and focuses infrared radiation from the target area onto the detection sensor. This intermediary structure enables the forehead thermometer to accurately measure temperature at longer distances and reduces sensitivity to environmental factors by concentrating the thermal radiation signal
Solution Approach 2:
The reflecting shell utilizes curved reflective surfaces to focus infrared radiation from a specific direction (forehead or ear) onto the detection sensor. The curved geometry of the reflecting shell helps concentrate thermal radiation and improve measurement accuracy by directing more radiation energy to the sensor
3Adaptability or versatility
If separate ear thermometer and forehead thermometer are used, then measurement versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates both ear thermometer and forehead thermometer functions into a single device. The temperature detection device includes an ear detection module with reflecting shell and a forehead detection module, allowing users to measure both ear and forehead temperatures with one device, reducing the need to carry multiple separate thermometers
Solution Approach 2:
The temperature detection device is designed with multi-functionality to perform both ear temperature measurement (using the reflecting shell) and forehead temperature measurement (using the non-contact sensor). This universal device can adapt to different measurement needs, replacing the requirement for separate specialized thermometers

AI summary
A reflecting shell includes a hollow joint unit, a hollow guide unit and a hollow receiving unit. The hollow joint unit has a stationary part at one end, and the stationary part is detachably connected to a detecting part of a measuring device. One end of the hollow guide unit is connected to the other end of the hollow joint unit, and an internal wall of the hollow guide unit has a first reflective surface and a second reflective surface, in which the first reflective surface and the second reflective surface correspond to each other. One end of the hollow receiving unit is connected to the other end of the hollow guide unit. Heat radiation from a heat source enters the hollow guide unit, and the heat radiation is transmitted to the detecting part by the reflection of the first reflective surface and the second reflective surface.
