Solution Overview
Problem
Conventional systems for measuring and analyzing brain functions lack standardization in measurement procedures, leading to variability in results and making objective comparison of brain function measurements challenging across different operators.
Innovation Solution
A biological function measurement and analysis system that includes an input acceptance unit for selecting a biological function to be measured, and a measurement and analysis procedure determining unit that accesses a memory storing procedure data specific to each biological function, allowing for standardized measurement and analysis procedures based on pre-defined combinations of stimulation and analysis programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional systems allow operators to freely select and customize measurement procedures, then ease of operation is improved, but measurement precision and reliability deteriorate due to lack of standardization
Solution Approach 1:
The system pre-prepares and stores standardized measurement procedure data in a database before actual measurements are performed. Each procedure includes pre-defined stimulation parameters, measurement settings, and analysis methods specific to each biological function, eliminating the need for operators to customize procedures during operation.
Solution Approach 2:
The system changes the operational mode from allowing free parameter customization to enforcing standardized parameter selection. The measurement procedure determining unit automatically selects appropriate parameters from pre-stored data based on the selected biological function, ensuring consistency while maintaining ease of operation through simple function selection.
2Measurement precision
If measurement procedures are standardized across different operators, then measurement precision is improved, but device complexity increases due to need for structured procedure management
Solution Approach 1:
The system employs a universal database structure and procedure determining unit that can handle multiple biological functions through a single standardized framework. The same hardware and software infrastructure serves all measurement types, achieving standardization without proportionally increasing complexity for each additional function.
Solution Approach 2:
The measurement procedure determining unit acts as an intermediary between the operator's simple function selection and the complex measurement parameters. It automatically retrieves and applies appropriate standardized procedures from the database, shielding operators from complexity while ensuring precise, consistent measurements.
3Measurement precision
If detailed function-specific procedure data is stored for each biological function, then measurement precision is improved, but loss of information increases due to larger data storage requirements
Solution Approach 1:
The system segments measurement procedure data into distinct, function-specific units in the database. Each biological function has its own standardized procedure data set, allowing efficient storage and retrieval without mixing unrelated parameters. This segmentation enables precise measurements while optimizing storage by only storing necessary function-specific information.
