Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If relay stations are successively disconnected to expand wireless communication range, then the relay coverage area is improved, but the number of relay stations required increases excessively
Solution Approach 1:
The patent implements dynamic adjustment of relay station operations based on real-time signal intensity measurements. The base station controller monitors signal conditions and dynamically determines which relay stations should be connected or disconnected, allowing the system to expand coverage area without permanently maintaining excessive numbers of relay stations. This dynamic control resolves the contradiction by making the relay network adaptable to actual communication needs.
Solution Approach 2:
The system incorporates feedback mechanisms where signal intensity values are continuously measured and reported to the base station controller. Based on this feedback, the controller adjusts the operational status of relay stations accordingly. This feedback loop enables the system to maintain optimal coverage area while minimizing the number of actively operating relay stations, as stations are only activated when signal conditions require their participation.
2Reliability
If too many relay stations are prepared for communication range, then coverage reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of relay station operations based on real-time signal intensity measurements. The base station controller monitors signal conditions and dynamically determines which relay stations should be connected or disconnected, allowing the system to maintain reliable coverage only when and where needed. This dynamic control resolves the contradiction by making the relay network adaptable to actual communication needs rather than maintaining static over-provisioning.
Solution Approach 2:
The system changes operational parameters (connection/disconnection status) of relay stations based on measured signal intensity values. When signal intensity exceeds thresholds, relay stations are disconnected; when thresholds are violated, they are reconnected. This parameter-based control ensures reliability is maintained at minimum necessary levels, optimizing resource utilization efficiency.
3Stability of the object's composition
If relay stations remain in operation when unnecessary, then system stability is improved, but energy consumption increases
Solution Approach 1:
The patent implements a mechanism where relay stations are disconnected (discarded from active operation) when they become unnecessary based on signal intensity measurements, and reconnected (recovered) when needed. The base station controller monitors signal conditions and dynamically determines which relay stations should be disconnected to save energy. This discard-and-recover approach resolves the contradiction by maintaining system stability through selective reconnection while eliminating unnecessary energy consumption.
Solution Approach 2:
The system changes the operational state parameter of relay stations based on signal intensity thresholds. When signal quality is sufficient, relay stations are transitioned to a disconnected state, reducing energy consumption. When signal quality deteriorates below thresholds, they are transitioned back to connected state, maintaining system stability. This parameter-based state management resolves the contradiction between stability and energy efficiency.

AI summary
The number of unmanned wireless relay mobile units in operation is adjusted to an appropriate number according to a usage status. A communication unit that relays a wireless signal, a signal intensity measurement unit that measures a signal intensity value, and a request unit that communicates, by means of the communication unit, a request signal to request addition or elimination of an unmanned wireless relay mobile unit, to a wireless base station are included. In a case where an unmanned wireless relay mobile unit is in direct communication with the wireless base station, its request unit transmits a request signal to request addition of another unmanned wireless relay mobile unit when a base station signal intensity value is smaller than a first threshold or when a relay signal intensity value for a relay destination is smaller than a third threshold.
