Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If brain information is transmitted at high speed among multiple users, then real-time intention conveyance is achieved, but the processing capacity of individual users is exceeded causing information overload

Engineering Contradiction:

Improvetransmission speed of brain informationVSAvoidsmoothness of intention conveyance

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system dynamically adjusts the transmission speed parameter based on each user's measured processing capacity. By changing the transmission speed parameter to match individual brain processing capabilities, the system achieves real-time intention conveyance without causing information overload, thus resolving the contradiction between transmission speed and conveyance smoothness

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system measures each user's brain processing capacity in real-time and uses this feedback to adjust the information transmission rate. This closed-loop feedback mechanism ensures that transmission speed adapts to individual processing capacities, preventing information overload while maintaining real-time communication effectiveness

Inventive Principle:

Principle #23Feedback

2Productivity

If the amount of brain information transmitted per unit time is increased, then intention conveyance efficiency is improved, but the user's processing capacity is exceeded

Engineering Contradiction:

Improveintention conveyance efficiencyVSAvoidinformation overload

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system adjusts the information transmission rate parameter according to each user's processing capacity measurements. By optimizing this parameter, the system maximizes intention conveyance efficiency while keeping the transmission amount within each user's processing capacity, thereby preventing information overload

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The transmission rate is made dynamic rather than static, adjusting in real-time based on each user's measured processing capacity. This dynamic adaptation allows the system to optimize conveyance efficiency for each user while automatically preventing information overload by reducing transmission when capacity is exceeded
