Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If static base stations are used to provide broad coverage, then coverage area is improved, but adaptability to real-time user needs deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transitioning from static base stations to mobile nodes that can move and reposition dynamically. The nodes are deployed on mobile platforms (vehicles, drones, boats) and can change their locations in real-time to follow user movements and adapt coverage to actual user needs, resolving the contradiction between maintaining broad coverage and adapting to real-time requirements.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting propagation characteristics (transmission power, antenna direction, frequency) of mobile nodes based on real-time user location and environmental conditions. The planning and control module continuously modifies these parameters to optimize coverage and spectrum reuse, enabling the system to adapt to changing user needs while maintaining efficient spectrum utilization.
2Productivity
If static base stations are positioned for optimal spectrum reuse, then spectrum efficiency is improved, but real-time adaptability to environmental conditions deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where mobile nodes continuously monitor user location, signal quality, and environmental conditions, and this information is fed back to the planning and control module. The module uses this feedback to dynamically adjust node positions and propagation characteristics in real-time, optimizing spectrum efficiency while adapting to changing environmental conditions and user needs.
Solution Approach 2:
The system transitions from static to dynamic operation, where mobile nodes can change their positions and propagation characteristics in real-time based on feedback from the environment and user devices. This dynamic behavior enables the system to maintain optimal spectrum efficiency while adapting to real-time conditions, resolving the contradiction between the two objectives.
3Adaptability or versatility
If mobile nodes are deployed to follow user locations, then adaptability to user needs is improved, but network complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the network into autonomous mobile nodes, each equipped with its own planning and control module. This distributed architecture allows each node to independently manage its coverage area and make local decisions, reducing overall network complexity while maintaining high adaptability to user needs through localized autonomous operation.
4Manufacturing precision
If dynamic adjustment of propagation characteristics is implemented, then coverage optimization is improved, but energy consumption increases
Solution Approach 1:
The patent implements partial action by dynamically adjusting propagation characteristics only when and where needed, rather than continuously maximizing transmission across all nodes. The planning and control module optimizes transmission power and antenna characteristics based on actual user requirements and signal conditions, reducing unnecessary energy consumption while maintaining coverage optimization through targeted adjustments.
