Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If brain activity measurement is performed using bloodflow rate detection, then brain activity states can be measured, but it becomes difficult to analyze and select appropriate brain training content tailored to individual users

Engineering Contradiction:

Improvebrain activity measurementVSAvoidindividualized brain training selection

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by transforming raw bloodflow rate detection values into standardized brain activity values through normalization processing. This allows the system to convert physiological measurements into comparable parameters that can be used for individualized assessment and training content selection, resolving the contradiction between measurement capability and adaptability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments the brain activity analysis by dividing users into different groups based on their brain activity characteristics. By segmenting users according to their measured brain activity patterns, the system can provide tailored training content for each segment, thereby achieving individualized training selection from the measured brain activity data.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple categories of brain training content are provided, then more options are available for users, but it becomes difficult to select the suitable content for each user

Engineering Contradiction:

Improvebrain training content varietyVSAvoidselection process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback by using measured brain activity values to automatically determine and recommend appropriate training content categories. The system provides feedback loops where user performance and brain activity measurements inform subsequent content selection, simplifying the choice process while maintaining content variety suitable for each user's needs.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by making the training content selection adaptive and changeable based on measured brain activity. The system dynamically adjusts content recommendations according to real-time or historical brain activity data, allowing the selection process to evolve with user progress rather than being static or overly complex.

Inventive Principle:

Principle #15Dynamics
