Biosensor Pinching Portion for Secure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biosensors are difficult to attach and remove from blood-sugar measuring devices due to their small size and flat surfaces, leading to potential slippage and contamination issues, especially for users with weakened muscle strength, and pose hygiene concerns when handling multiple patients.
Innovation Solution
A biosensor design featuring a pinching portion with recesses or projections, including a curved surface for easier handling, and a counter-disturbance noise electrode to manage static electricity and prevent measurement errors, facilitating secure attachment and removal while preventing sample adherence to fingertips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the biosensor is made small and flat, then the device size is reduced and portability is improved, but the ease of attachment and removal deteriorates
Solution Approach 1:
The biosensor is segmented into distinct functional regions: a flat main body for miniaturization and a protruding pinching portion for ease of handling. This segmentation allows the small size requirement to be satisfied by the main body while the pinching portion provides the necessary grip area for easy attachment and removal operations.
Solution Approach 2:
The pinching portion extends in the thickness direction (z-axis) from the flat biosensor body, adding a dimensional element that provides grip leverage. This dimensional extension allows users to pinch the biosensor from the side rather than requiring finger pressure on the flat surfaces, significantly improving ease of operation while maintaining the compact form factor.
2Ease of manufacture
If the biosensor surfaces are flat, then the manufacturing is simplified, but the ease of pinching and handling deteriorates
Solution Approach 1:
The biosensor structure is divided into a flat main body (easy to manufacture) and a separate pinching portion protruding in the thickness direction. This segmentation maintains manufacturing simplicity for the majority of the device while adding a localized feature that dramatically improves pinching ease.
Solution Approach 2:
Only the pinching portion requires the protruding geometry to improve handling, while the rest of the biosensor maintains its simple flat structure for easy manufacture. This local application of complexity achieves the handling improvement without significantly complicating the overall manufacturing process.
3Device complexity
If no specific pinching portion is defined, then the device structure is simplified, but the hygiene and contamination control deteriorates
Solution Approach 1:
The pinching function is extracted from the main biosensor body and implemented as a separate pinching portion. This extraction ensures that the pinching operation occurs at a designated area远离 from the blood inlet and outlet, preventing blood contamination of the user's fingers while maintaining structural simplicity.
Solution Approach 2:
The pinching portion acts as an intermediary element between the user's fingers and the biosensor's functional components. It provides a designated grip area that mediates the interaction, allowing users to handle the biosensor without their fingers contacting the blood inlet/outlet areas, thus preventing contamination.
