Solution Overview
Problem
Existing biological light measuring devices face challenges with heat generation from control boards, weight balance, and installation properties, which affect precision and user comfort due to obstructed freedom of movement and insecurity for test subjects.
Innovation Solution
A probe device with a sheet-like probe holding body, alternately arranged light emitting and detection probes, a board holding portion for electronic boards, and a flexible sheet holding portion that provides good weight balance, easy installation, and minimizes heat impact, while allowing for rotational adjustment of probes to accommodate different head shapes and reduce hair obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If electronic control boards are integrated into the probe device, then measurement control capability is improved, but heat generation affects measurement precision
Solution Approach 1:
The device is divided into separate functional modules: electronic control boards are separated from the probe head and integrated into the main body housing. This segmentation allows the probe head to remain lightweight and cool while the electronic components are isolated in a separate compartment, eliminating heat interference with measurements.
Solution Approach 2:
A flexible cable system acts as an intermediary connection between the probe head and the electronic control boards in the main body. This allows electrical signals to be transmitted while physically separating the heat-generating electronic components from the sensitive measurement area, serving as a thermal barrier.
2Measurement precision
If multiple fibers are attached around the head portion, then light transmission and detection are improved, but freedom of behavior is obstructed and sense of insecurity increases
Solution Approach 1:
Multiple optical fibers are bundled together into a single integrated cable that connects the probe head to the main body. This merging reduces the number of separate fiber attachments around the user's head, minimizing obstruction of movement and reducing the sense of insecurity while maintaining full light transmission and detection capability.
3Stability of the object's composition
If probe device is firmly pressed to head portion using fixing belt, then installation stability is improved, but weight balance and installing property are worsened
Solution Approach 1:
The probe head is designed with a curved, ergonomic shape that conforms to the natural curvature of the human head. This curved design allows the device to fit comfortably against the head surface without requiring strong compression from fixing belts, improving both stability and weight balance while maintaining ease of installation.
