Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed IoT devices communicate in a smart environment without time synchronization, then device autonomy and flexibility are improved, but communication collisions and interference increase
Solution Approach 1:
The patent implements periodic time-synchronized communication slots where IoT devices transmit data at predetermined intervals based on a common time reference. This periodic structure ensures that devices in different locations transmit during designated time windows, preventing communication collisions while maintaining device autonomy within each time slot.
Solution Approach 2:
The patent introduces a time synchronization server as an intermediary that distributes synchronized time references to all IoT devices in the smart environment. This mediator enables coordinated communication without requiring direct device-to-device negotiation, resolving the conflict between autonomy and communication reliability.
2Reliability
If IoT devices use centralized control for navigation and protection, then coordination and collision avoidance are improved, but system complexity and communication overhead increase
Solution Approach 1:
The patent segments the control function into two parts: time synchronization management is centralized through a synchronization server, while navigation and protection decisions are decentralized to individual IoT devices. Each device independently calculates its position and makes avoidance decisions based on the synchronized time reference, reducing overall system complexity while maintaining coordination efficiency.
Solution Approach 2:
The patent implements preliminary time synchronization before navigation and protection operations begin. By pre-establishing a common time reference across all devices, the system enables autonomous decision-making without requiring complex real-time centralized coordination, thus reducing system complexity while maintaining reliability.
3Measurement precision
If precise time synchronization is implemented across all IoT devices, then navigation accuracy and collision avoidance are improved, but network load and processing requirements increase
Solution Approach 1:
The patent implements partial time synchronization by providing time reference information at a granularity sufficient for navigation and protection purposes, rather than continuous high-precision synchronization. This approach achieves the necessary navigation accuracy while reducing network load and processing requirements compared to full continuous synchronization.
Solution Approach 2:
The patent enables IoT devices to autonomously calculate their positions and make navigation decisions using the synchronized time reference, without requiring continuous network communication for each decision. Devices use local processing to determine positions based on time-stamped signals from other devices, reducing network load while maintaining navigation precision.
