Forehead Thermometer Layout for Easier Self-Measurement Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held non-contact thermometers are difficult to use for self-temperature measurement due to the need for awkward arm and wrist postures, and can cause discomfort when used on others, especially with a pistol-shaped design.
Innovation Solution
A hand-held non-contact thermometer with a rod-shaped casing and a flat sensor surface inclined at an angle, featuring a measurement button on the same side as the sensor, allowing easy adjustment of positional relationship and distance without requiring uncomfortable postures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pistol-shaped non-contact thermometer with a long cylindrical portion is used, then the positional relationship and distance can be adjusted by visual observation, but it requires unreasonable arm and wrist postures and causes discomfort when measuring oneself
Solution Approach 1:
The patent introduces a visual indicator (cylindrical portion or marking) that extends perpendicular to the sensor surface, creating a new visual dimension for alignment. This allows users to adjust the thermometer's position and angle by observing the indicator's orientation rather than directly observing the sensor, solving the self-measurement problem where the sensor is too close to observe.
Solution Approach 2:
The patent uses a cylindrical portion or visual marking as an intermediary element between the sensor and the user's line of sight. This intermediary provides a visible reference that mediates the alignment process, allowing indirect observation and adjustment of the sensor's positional relationship with the measurement site.
2Measurement precision
If a pistol-shaped non-contact thermometer is used to measure another person, then the sensor can be positioned correctly, but it causes a sense of discomfort or unpleasantness to the subject
Solution Approach 1:
The patent extracts the visual alignment function from the sensor itself and places it on a separate cylindrical portion or marking. This separation allows the sensor to be small and non-intrusive while the larger cylindrical indicator handles the visual guidance, reducing the intrusive appearance of the sensor when pointed at the subject's face.
Solution Approach 2:
The patent may use visual markings or color-coded indicators on the cylindrical portion to provide clear alignment guidance. These visual elements help users quickly identify the correct positioning without requiring the sensor itself to be large or prominent, thereby reducing discomfort to the subject.
3Measurement precision
If the cylindrical portion is made long to facilitate visual observation, then the positional relationship can be adjusted, but it becomes burdensome to maintain the required arm and wrist postures
Solution Approach 1:
The patent creates a visual reference dimension perpendicular to the sensor surface, allowing alignment to be achieved through angular observation rather than requiring precise linear positioning. This dimensional change reduces the need for extreme arm and wrist positions, making the measurement process more sustainable.
Solution Approach 2:
The patent makes the visual indicator (cylindrical portion) dynamically visible from different angles, allowing users to adjust their viewing position and the thermometer's orientation flexibly. This dynamic visual guidance system accommodates various arm and wrist positions, reducing the burden of maintaining fixed postures.
