Ergonomic Electronic Thermometer Inverted Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held electronic thermometers are difficult to hold and operate with one hand due to their top-heavy design, with the LCD screen positioned above the buttons, making them awkward to use.
Innovation Solution
The design features a housing with a control panel above the display screen, allowing for one-handed operation, a probe well on the backside for secure probe storage, and an ergonomic shape that accommodates the natural position of the thumb, ensuring easy access to buttons without blocking the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the LCD screen is positioned above the buttons, then the display is easily visible, but the thermometer becomes top-heavy and awkward to hold
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the control panel above the display screen instead of below. This inversion repositions the heavy components (buttons and control panel) toward the top, balancing the weight distribution and allowing the user to operate the device comfortably with one hand while keeping the display visible below.
2Illumination intensity
If the control panel is positioned below the display screen, then the display is easily viewed, but the user cannot access the buttons without blocking the screen
Solution Approach 1:
The patent reverses the conventional layout by placing the control panel above the display screen. This allows the user's thumb to naturally access the buttons without obstructing the display, as the thumb operates from the top while the display is positioned below for clear viewing.
3Volume of moving object
If the probe is stored in the probe well, then the thermometer is compact, but the probe can be unintentionally removed
Solution Approach 1:
The patent incorporates a latch mechanism that automatically engages when the probe is inserted into the probe well. This preliminary anti-action prevents unintentional removal by requiring a deliberate unlatching action, thus maintaining both compact storage and reliable probe retention.
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
Enables comfortable, balanced, and efficient one-handed use of the thermometer, with the control panel and display screen positioned for optimal accessibility, reducing muscle exertion and preventing accidental probe removal.
Implementation Method 1
Electronic temperature sensors such as thermistors or other temperature sensitive elements are contained within a tip of the probe. When the tip is placed, for example, in a patient's mouth, the tip is heated up by the patient's body and the thermistor measures the temperature of the tip
