Robot Head Orientation for Body Temperature Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current service robots with fixed temperature measurement angles require users to move to a designated position, leading to inefficient and time-consuming temperature measurement processes.
Innovation Solution
A method and apparatus that determine the orientation of a target user using a pyroelectric sensor, adjust the robot's head to align a thermopile temperature sensor with the user, and measure body temperature without requiring the user to move, utilizing horizontal and pitching rotating steering gears to ensure accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed temperature measurement angle is used, then the device structure is simple, but the measurement efficiency is low and users must move to a designated position
Solution Approach 1:
The patent applies the dynamics principle by making the robot's head movable instead of fixed. The head can rotate and tilt to track users in real-time, allowing the temperature measurement device to dynamically adjust its measurement angle according to user position, thereby eliminating the need for users to move to designated positions and significantly improving measurement efficiency
Solution Approach 2:
The patent implements feedback through sensors (such as infrared sensors or cameras) that detect user position and provide real-time information to the control system. The control system then adjusts the head's orientation based on this feedback, creating a closed-loop system that continuously optimizes the measurement angle to maintain high measurement efficiency
2Loss of time
If users must travel to a designated position for temperature measurement, then the measurement accuracy is ensured, but the measurement time increases
Solution Approach 1:
The patent applies inversion by reversing the traditional approach: instead of requiring users to move to a fixed measurement position, the measurement device moves (via head rotation and tilting) to track the user's position. This inverted approach maintains measurement accuracy by ensuring the sensor always faces the user while dramatically reducing the time users need to spend moving
Solution Approach 2:
The system performs preliminary detection of user position and orientation before initiating temperature measurement. By pre-positioning the head to face the user and confirming proper alignment, the system ensures measurement accuracy is established beforehand, allowing immediate measurement without requiring user movement while maintaining precision standards
