Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wireless communication is used to control camera devices, then user mobility is maintained, but the control range is limited and blocked by obstacles
Solution Approach 1:
The patent introduces location stations as intermediary devices between the user and camera devices. These stations receive wireless commands from users, convert them to optical signals transmitted through fiber optic cables (which can penetrate obstacles and extend distance), convert received optical signals back to wireless signals, and forward them to camera devices. This intermediary system resolves the contradiction by using fiber optic cables as a mediator that is not affected by obstacles while maintaining wireless convenience at both ends.
2Adaptability or versatility
If hard cable connections are used to extend control distance, then control range is extended, but user and device mobility are restricted
Solution Approach 1:
The system segments the communication path into three independent segments: wireless communication from user to location station, optical communication through fiber optic cable between location stations, and wireless communication from location station to camera device. This segmentation allows each segment to be optimized independently - wireless segments provide mobility while the optical cable segment provides extended distance without restricting movement at the endpoints.
Solution Approach 2:
Location stations act as intermediaries that convert between wireless and optical domains. The stations receive wireless signals from mobile users and camera devices, then transmit control commands and feedback through the fiber optic infrastructure. This mediation allows both user and camera devices to remain mobile while achieving extended control distances through the stationary fiber optic backbone.
3Ease of operation
If wireless signals are transmitted over long distances, then user mobility is maintained, but signal reception is impaired by obstacles
Solution Approach 1:
The location stations serve as reliable intermediaries that receive wireless signals within short range (where reception is reliable), then retransmit them through the obstacle-proof fiber optic cable system. This two-stage transmission approach maintains wireless mobility at the user end while ensuring reliable signal delivery over long distances through the optical medium that is immune to electromagnetic interference and physical obstacles.

AI summary
Systems to extend signal transfer used with a camera device comprise a first location station with a first receiver and a second receiver. The first receiver receives wireless signals from a user device that are changed and sent through a fiber optic cable to a second location station. The second receiver receives signals through the cable from the second location station, which signals are changed to wireless signals output to a user device. The second location station comprises a third receiver that receives from the cable from the first location station, which signals are changed to wireless signals output to a camera device. The second location comprises a fourth receiver that receives wireless signals from the camera device, which signals are changed at the first location to signals sent through the cable from the second location station to the first location station.
