Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser blood-stream measuring devices apply pressure on capillary vessels, leading to reduced signal quality and variability in bio-information measurement due to improper attachment methods, especially when used in non-medical contexts.
Innovation Solution
A bio-information measuring apparatus featuring a self-emission-type sensor device attached to an elastic attaching member with a hollow structure, where the sensor is positioned within the hollow and an elastic member is used to minimize pressure on the specimen, ensuring stable contact and reduced capillary vessel compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the containing case is formed into a plane surface for contacting the body, then the device can be easily attached and positioned, but the capillary vessels are pressed and blood stream is prevented, lowering the S/N ratio
Solution Approach 1:
The contacting surface is changed from a flat plane to a curved surface that conforms to the body contour. This curvature allows the device to adapt to the rounded shape of body parts (such as fingers) without creating concentrated pressure points that would compress capillary vessels, thereby maintaining blood flow and signal quality while ensuring proper attachment.
Solution Approach 2:
The hardness or elasticity parameter of the contacting surface material is modified to reduce pressure application. By using a softer or more compliant material, the device can maintain contact with the body surface without exerting sufficient force to compress capillary vessels, thus preserving blood flow and optical signal quality.
2Adaptability or versatility
If the laser blood-stream measuring device is attached to devices such as headphones or headsets, then the device can be used in entertainment applications, but the attaching method varies widely and cannot achieve good S/N ratio
Solution Approach 1:
The device is designed with a universal attaching mechanism that can be applied to various carriers (headphones, headsets, or standalone use). The key feature is the curved contacting surface that maintains consistent performance across different attachment scenarios, ensuring that capillary vessels are not compressed regardless of how the device is positioned or attached.
Solution Approach 2:
The attaching mechanism incorporates dynamic elements that allow the device to adapt to different positions and pressures. The elastic or flexible components enable the device to maintain optimal contact with the body surface while accommodating variations in attachment method, ensuring consistent measurement quality across different use cases.
