Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional healthcare devices require specific user positioning and posture for accurate biometric measurements, which can be inconvenient and may lead to measurement failures if not used correctly, and often rely on physical keys or separate input devices for operation.
Innovation Solution
An electronic device with a sensor module to measure load and an electrode module that allows biometric information to be measured without user directionality, using a controller to recognize electrode pairs and output information intuitively based on weight center shifts, eliminating the need for physical keys or separate input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the healthcare device requires specific user positioning and posture for measurement, then measurement accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The device dynamically adapts to the user's posture and position rather than requiring the user to adapt to a fixed position. The controller detects the user's actual posture through sensors and adjusts the measurement process accordingly, allowing measurements to be taken in various positions while maintaining accuracy.
Solution Approach 2:
The device performs self-adjustment by automatically detecting user position and configuring measurement parameters without requiring user intervention. The system autonomously adapts to the user's natural posture, eliminating the need for the user to consciously position themselves correctly.
2Device complexity
If the healthcare device uses physical keys for operation, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent replaces mechanical physical keys with touch-based or gesture-based input methods on a display interface. Users can operate the device by touching the display screen or making gestures, eliminating the need for separate physical buttons while maintaining intuitive control.
Solution Approach 2:
The display screen serves multiple functions: it displays information, provides input through touch gestures, and replaces the functionality of physical keys. This multi-functional approach consolidates the interface elements, reducing overall device complexity while enhancing ease of operation.
3Device complexity
If the healthcare device displays biometric information in a fixed direction, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The display dynamically adjusts its orientation and content based on the detected user position and posture. The controller receives position information from sensors and automatically configures the display to face the correct direction, allowing the device to adapt to various user positions without manual intervention.
