Biological Sample Measuring Device with Orientation-Aware Touch Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological sample measuring devices with mechanical input buttons become cumbersome as functions increase, making it difficult for users to intuitively identify the purpose of each button, and there is a risk of accidentally touching the blood sensor during input operations.
Innovation Solution
A biological sample measuring device with a touch input-type display that includes a first area for displaying measurement values and a second area for displaying input buttons, where the acceleration sensor detects the device's orientation and rotates the displays 180 degrees to keep input buttons on the opposite side of the sensor mounting component, preventing finger contact with the sensor and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mechanical input buttons are disposed around the display component, then the device structure is simple, but as functions increase the buttons become non-intuitive and hard to use
Solution Approach 1:
The patent replaces physical mechanical buttons with virtual button images displayed on the touch panel. These virtual buttons are graphical representations that replicate the function of physical buttons but are rendered on the display surface, allowing users to interact through touch input rather than mechanical pressing. This resolves the contradiction by maintaining functional simplicity while improving intuitiveness through visual feedback.
Solution Approach 2:
The patent substitutes the mechanical button system with a touch-based graphical interface system. Instead of relying on physical mechanical components that require direct contact and pressing, the system uses a touch-sensitive display with visual button representations, replacing mechanical interaction with electronic touch detection and visual feedback mechanisms.
2Area of stationary object
If input buttons are disposed around the display component, then the device layout is compact, but user fingers may accidentally touch the sensor during input operations
Solution Approach 1:
The patent resolves the spatial conflict by transitioning from a two-dimensional physical layout where buttons surround the display to a layered dimensional arrangement where virtual buttons are overlaid on the touch panel surface. This allows the button interface and sensor area to coexist in the same physical space without interference, as the touch input layer separates user interaction from the underlying sensor mounting area.
3Ease of operation
If the device orientation is inverted, then the display appears rotated and difficult to read, but physically rotating the device requires additional mechanical adjustment
Solution Approach 1:
The patent implements dynamic display orientation that automatically adapts to the device's physical orientation. The display content, including virtual buttons and text, rotates or reorients based on the acceleration sensor detection of device orientation, providing continuous readability without requiring manual mechanical adjustment. This dynamic adaptation resolves the contradiction by making the display responsive to orientation changes rather than fixed.
Solution Approach 2:
The patent employs feedback from the acceleration sensor to automatically adjust display orientation. The sensor continuously monitors device orientation and provides feedback signals to the control unit, which then rotates or repositions display elements accordingly. This closed-loop feedback system ensures the display remains readable regardless of device orientation, eliminating the need for manual adjustment while maintaining simplicity.
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
The solution provides a more intuitive and convenient user experience by clearly displaying input buttons on a separate area from the sensor, preventing accidental contact and improving usability, especially when the device is inverted.
Implementation Method 1
an acceleration sensor connected to the controller and operable to sense an orientation of the main body case
Data Source
AI summary
The controller divides a display of the display component provided to the main body case into a first display area that is disposed on a sensor mounting component side and displays measurement values, and a second display area that is disposed on the opposite side from the sensor mounting component side and displays input buttons. When the acceleration sensor has detected that the orientation of the main body case is inverted in a horizontal direction, the controller rotates a display of the first display area and a display of the second display area 180 degrees within each of these areas.
