Solution Overview
Problem
Existing biometric information measuring devices require users to manually recognize and align electrode arrays, which can be cumbersome and lead to inaccurate measurements if not placed correctly, lacking convenience and reliability.
Innovation Solution
An electronic device equipped with a complex location sensor unit, biometric information measurement unit, and a switch unit, controlled by a controller that automatically recognizes the electrode array's attitude and adjusts it to match a preset configuration, ensuring accurate biometric information measurement without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device uses a fixed electrode array configuration, then the device structure is simple, but the user must manually align electrodes correctly which increases operation difficulty and reduces ease of use
Solution Approach 1:
The electrode array configuration is made dynamic and adaptable rather than fixed. The controller automatically adjusts the electrode array based on detected body parts, allowing the system to adapt to different measurement scenarios without requiring manual alignment by the user.
Solution Approach 2:
The system performs self-alignment and selfconfiguration of the electrode array. The controller automatically detects which body part is being measured and configures the appropriate electrode array, eliminating the need for user intervention in the alignment process.
2Measurement precision
If the electronic device requires manual electrode alignment, then the device structure is simple, but measurement accuracy decreases when users cannot properly align the electrodes
Solution Approach 1:
The system uses feedback from body part detection to automatically adjust the electrode array configuration. The controller detects which body part is being measured and uses this information to automatically configure the appropriate electrode array, ensuring measurement accuracy without requiring user knowledge of proper alignment.
3Adaptability or versatility
If the electronic device provides multiple electrode array configurations, then adaptability to different body parts improves, but the complexity of controlling and switching between configurations increases
Solution Approach 1:
The system automatically selects and configures the appropriate electrode array based on detected body parts. The controller performs selfconfiguration by detecting which body part is being measured and automatically switching to the appropriate electrode array configuration, eliminating the need for manual control complexity.
4Ease of operation
If the electronic device automatically adjusts electrode array, then ease of use improves, but the device requires complex sensors and control mechanisms
Solution Approach 1:
The body part detection unit serves multiple functions: it detects which body part is being measured and provides this information to the controller for automatic electrode array configuration. This multi-functionality reduces the need for separate control mechanisms while improving ease of use.
