Biometric Sensor Unit Segmentation for Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric sensors used to acquire biological information often face contamination issues due to contact with sweat or oil, leading to shortened device lifespan and unstable measurements, especially in varying usage situations and individual differences, which can increase costs when replacing sensors for different scenarios.
Innovation Solution
A biological-information acquisition device design where the biometric sensor unit is detachable and replaceable, allowing only the sensor to come into contact with the body, while the main body unit remains non-contact and reusable, preventing contamination and adapting to different situations without increasing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the biometric sensor unit is made replaceable and detachable from the main body, then contamination of the main body is prevented and adaptability to various usage situations is improved, but device complexity increases due to the detachable connection mechanism
Solution Approach 1:
The device is divided into two independent parts: a biometric sensor unit that contacts the living body and a main body unit that does not. The sensor unit can be detached and replaced independently, preventing contamination of the main body while maintaining functional integrity. This segmentation allows the sensitive measurement component to be isolated from the main processing unit.
Solution Approach 2:
The main body unit is designed with universal compatibility to work with multiple different biometric sensor units. The detachable connection mechanism allows users to swap sensor units for different measurement purposes or living body types while reusing the same main body, reducing overall system complexity and cost.
2Adaptability or versatility
If the biometric sensor unit is made replaceable, then adaptability to various usage situations and individual differences is improved, but manufacturing costs increase due to multiple sensor units
Solution Approach 1:
The main body unit is designed with universal compatibility to work with multiple different biometric sensor units. This allows a single main body to serve multiple measurement purposes and accommodate different living body types, reducing the need to manufacture entirely different devices for each application scenario.
Solution Approach 2:
The biometric sensor unit is designed as a replaceable, potentially disposable component that can be manufactured at lower cost compared to a fully integrated device. By making only the sensor portion replaceable rather than the entire device, the system achieves adaptability while controlling manufacturing costs through standardized main body units.
3Ease of operation
If the main body is detachably attached to the biometric sensor unit, then ease of operation is improved by allowing easy replacement, but reliability decreases due to potential connection issues
Solution Approach 1:
The detachable connection is designed with clear separation between the sensor unit and main body, featuring standardized connection interfaces. This segmentation allows for easy attachment and detachment while maintaining reliable electrical and mechanical connections during use, balancing operability with connection stability.

AI summary
A biological-information acquisition device is provided that includes a biometric sensor part including a biometric sensor that detects biological information and a living-body wearable part that enables the biometric sensor part to be in contact with a living body and a main body part including an information processing section that processes biological information and a battery that supplies power. The biometric sensor part is configured to be replaceable by being separated from the main body part, and the main body part is detachably attached to the biometric sensor in such a manner as not to come into contact with a living body when the biometric sensor part is worn on the living body.
