Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a repeater is installed in a hard-to-reach or restricted area to extend network coverage, then the network coverage range is improved, but the ease of operation for maintenance engineers deteriorates
Solution Approach 1:
The system segments the control function from the repeater hardware by introducing a separate remote control device that communicates with the repeater through wireless communication. This allows maintenance engineers to control and monitor the repeater remotely without needing to physically access the hard-to-reach installation location.
Solution Approach 2:
A remote control device serves as an intermediary between the maintenance engineer and the repeater. This intermediary enables control and monitoring functions to be performed remotely through wireless communication, eliminating the need for direct physical access to the repeater at difficult-to-reach locations.
2Device complexity
If a maintenance engineer physically accesses a repeater in a restricted area for control or monitoring, then the device complexity for remote control is reduced, but the safety and convenience of the engineer deteriorates
Solution Approach 1:
The remote control device acts as an intermediary that enables engineers to control and monitor repeaters without physically accessing restricted areas. This eliminates exposure to harmful factors such as high voltage, electromagnetic radiation, or dangerous environmental conditions at the repeater location.
Solution Approach 2:
The system replaces mechanical/physical access with wireless electronic communication. Instead of requiring physical presence at the repeater location for control or monitoring, the system uses wireless signals to transmit control commands and status information, eliminating the need for engineers to enter restricted areas.
3Reliability
If wired or wireless connection is applied for control within close range, then the reliability of control connection is improved, but the adaptability for various installation locations deteriorates
Solution Approach 1:
The system replaces wired mechanical connections with wireless electronic communication. This substitution maintains reliable control and monitoring capabilities while eliminating the constraint of requiring close physical proximity or complex wiring infrastructure, thereby enabling deployment at diverse installation locations including hard-to-reach areas.
Solution Approach 2:
The remote control device provides universal control capability that works across various installation locations without requiring location-specific infrastructure. The wireless communication approach enables the system to adapt to different environments (indoor, outdoor, restricted areas, hard-to-reach locations) while maintaining consistent control functionality.
