Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cloud-based communication is used for far field networks, then data transmission coverage is extended, but synchronization delay increases
Solution Approach 1:
The patent uses cloud servers as intermediaries for far-field communication, enabling data transmission across wide areas while managing synchronization through centralized coordination. The cloud server acts as a mediator that receives data from one device and distributes it to other devices, extending coverage while maintaining manageable synchronization delays through server-controlled timing and routing.
Solution Approach 2:
The system dynamically switches between direct device-to-device communication for near-field scenarios and cloud-mediated communication for far-field scenarios. This dynamic adaptation allows the system to optimize for low delay when devices are close while extending coverage when devices are distant, resolving the contradiction between coverage area and synchronization delay.
2Loss of time
If device-to-device communication is used for near field networks, then synchronization delay is reduced, but data transmission coverage is limited
Solution Approach 1:
The system dynamically selects communication paths based on device proximity and network conditions. For near-field devices, it uses direct peer-to-peer communication to minimize delay. For far-field devices, it transitions to cloud-mediated communication to extend coverage. This dynamic routing strategy resolves the contradiction by adapting the communication mode to the specific spatial context.
3Reliability
If continuous synchronization is performed in collaborative scenarios, then data consistency is maintained, but power consumption increases
Solution Approach 1:
The system implements periodic synchronization intervals rather than continuous synchronization. Devices synchronize data at predetermined time intervals or when specific change thresholds are met, maintaining data consistency while avoiding the excessive power consumption of continuous real-time synchronization. This periodic approach balances reliability requirements with energy conservation.
4Productivity
If traditional data transmission methods are used, then system complexity is low, but data transmission efficiency is poor
Solution Approach 1:
The system dynamically adapts transmission protocols and paths based on network conditions, device proximity, and data priority. This dynamic behavior improves transmission efficiency by selecting optimal routes and formats, but increases system complexity through the need for condition assessment and adaptive decision-making logic.
Solution Approach 2:
The patent segments data transmission into different channels and priorities, with different protocols for near-field and far-field communication, and different synchronization intervals for different data types. This segmentation improves overall efficiency by optimizing each segment for its specific requirements, but increases system complexity through the need to manage multiple transmission modes and protocols.
