Optical Brain Measurement Control System for Simultaneous Multi-Unit Readiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical measurement systems require cumbersome and time-consuming preparation when performing simultaneous brain function measurements with multiple units, as each unit must be individually checked for measurable conditions, such as communication status and battery level, before starting a measurement.
Innovation Solution
An optical measurement system with a control device that includes a communication unit to obtain state information from each optical measurement unit, a display unit to collectively show this information, and a control unit to facilitate simultaneous measurement by displaying which units are ready for measurement, allowing users to quickly identify and prepare only the necessary units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple optical measurement units are used for simultaneous brain function measurements, then the productivity and research efficiency are improved, but the preparation time and operational complexity increase due to the need to individually check each unit's measurable conditions
Solution Approach 1:
The patent merges the state checking operations for multiple optical measurement units into a single collective check performed by the control device. The control device simultaneously acquires state information from all measurement units through wireless communication, consolidating what would otherwise be individual sequential checks into one unified operation, thereby reducing preparation time while maintaining simultaneous measurement capability
Solution Approach 2:
The control device implements a feedback mechanism that automatically acquires and displays the measurable state information of each optical measurement unit. This feedback system provides real-time status updates on communication connectivity, battery levels, and measurement readiness, enabling operators to quickly identify and address units that are not ready without manual individual inspection
2Productivity
If multiple optical measurement units are used for simultaneous brain function measurements, then the productivity is improved, but the ease of operation deteriorates due to the need to individually confirm the measurable state of each unit
Solution Approach 1:
The control device performs self-service by automatically acquiring and managing the state information of all optical measurement units without requiring manual individual checks. The system autonomously monitors communication status, battery levels, and measurement readiness of each unit, and presents this information in a consolidated display, thereby maintaining operational simplicity while enabling simultaneous measurements with multiple units
Solution Approach 2:
The control device serves multiple functions: it controls each optical measurement unit individually, collects state information from all units simultaneously, displays the status of each unit, and manages the simultaneous measurement coordination. This multi-functional design consolidates what would otherwise require multiple separate operations into a single universal control interface
