Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional synchronization methods are used in low-bandwidth networks, then lighting devices can be controlled, but communication overhead becomes excessive and message drops cause disruptive light output changes
Solution Approach 1:
The system performs preliminary actions by calculating slopes and predicting future light output characteristics in advance, allowing devices to synchronize without continuous real-time communication. This reduces communication overhead while maintaining synchronization reliability.
Solution Approach 2:
Instead of continuously transmitting real-time clock data and synchronization messages, the system creates a simplified copy of the synchronization mechanism using slope calculations based on historical data, reducing communication bandwidth requirements while maintaining synchronization accuracy.
2Measurement precision
If real-time clocks are implemented in lighting devices, then precise synchronization is achieved, but processing power requirements and system complexity become impractical
Solution Approach 1:
The system replaces expensive, complex real-time clock hardware with a simpler, software-based slope calculation approach that uses readily available historical data, reducing device complexity while maintaining sufficient synchronization precision for dynamic lighting applications.
Solution Approach 2:
Lighting devices independently calculate their own synchronization parameters using locally stored historical data and slope calculations, eliminating the need for complex centralized clock synchronization mechanisms and reducing overall system complexity.
3Productivity
If frequent communication updates are sent to lighting devices, then dynamic lighting changes are accurately transmitted, but bandwidth consumption increases and message drops cause disruptions
Solution Approach 1:
The system transitions from continuous or frequent communication updates to periodic updates based on calculated intervals, reducing bandwidth consumption while maintaining dynamic lighting responsiveness. Devices use slope calculations to predict intermediate states between updates.
Solution Approach 2:
The system prepares for potential message drops by calculating slope-based predictions and storing intermediate state information in advance, cushioning against the impact of lost messages and ensuring seamless dynamic lighting transitions even when communication occurs intermittently.
