Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate interference detection mechanism is introduced, then interference detection capability is improved, but equipment cost increases
Solution Approach 1:
The communication apparatus performs dual functions: transmitting image data via optical space communication and detecting interference by monitoring transmission quality. This multi-functionality eliminates the need for separate dedicated interference detection equipment, reducing overall system cost while maintaining reliable interference detection capability.
Solution Approach 2:
The system uses its own communication transmission process to detect interference. By monitoring whether image data can be successfully transmitted and received, the system self-diagnoses interference conditions without requiring external monitoring equipment, thereby reducing equipment complexity and cost.
2Device complexity
If optical space communication is used for image data transmission, then equipment cost is reduced, but transmission reliability may be affected by external interference
Solution Approach 1:
The system establishes bidirectional communication between first and second communication apparatuses, where the second apparatus feeds back reception status to the first. This feedback mechanism allows real-time monitoring of transmission quality, enabling the system to detect interference conditions and adjust or retry transmissions, thereby maintaining reliability despite using cost-effective optical space communication.
Solution Approach 2:
The system proactively monitors transmission status and detects interference conditions before they cause complete communication failure. By continuously checking whether image data transmission succeeds, the system can take preliminary actions such as switching to alternative transmission methods or alerting operators, thus maintaining overall transmission reliability.

AI summary
A security camera monitoring system includes: a first communication apparatus that is attached to a security camera and can transmit, via optical space communication, image data obtained by the security camera to a second communication apparatus; the second communication apparatus that can receive the image data transmitted from the first communication apparatus; and a monitoring apparatus that can communicate with the second communication apparatus and monitors whether or not there is an interference from outside with respect to the security camera, the monitoring apparatus including at least one first processor which carries out a detection process of detecting a transmission failure of the image data from the first communication apparatus to the second communication apparatus, and a generation process of generating, based on a detection result in the detection process, a signal indicating occurrence of the interference.
