Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image is transmitted using a communication line for remote observation, then the operator can observe the image at a remote place, but the communication needs to be broadband and stable at all times which is not always feasible
Solution Approach 1:
The system dynamically adjusts image transmission parameters including resolution, frame rate, and field of view based on real-time communication conditions. The visual presentation apparatus monitors communication quality and adaptively modifies image parameters to maintain optimal observation under varying network conditions, resolving the contradiction between requiring stable broadband communication and the need to adapt to actual communication situations.
Solution Approach 2:
The system changes image parameters such as resolution, frame rate, and field of view according to communication situation monitoring results. By adjusting these parameters dynamically, the system can maintain reliable image transmission across varying communication conditions, transforming the rigid requirement for stable broadband connections into a flexible adaptive system.
2Measurement precision
If the image transmission rate is increased to maintain high quality, then the operator can observe detailed images, but the bandwidth usage increases which is not sustainable in limited communication conditions
Solution Approach 1:
The system applies different image quality levels to different regions of the display. The central field of view maintains higher resolution and frame rate for detailed observation, while peripheral regions use lower quality settings. This local quality differentiation allows the system to maintain necessary image precision where needed while reducing overall bandwidth consumption.
Solution Approach 2:
The image display is segmented into a central field of view region and a peripheral field of view region. Each region receives different transmission rates appropriate to its functional requirements. The central region receives high-quality transmission for detailed observation, while the peripheral region uses reduced transmission rates, effectively segmenting the bandwidth requirement.

AI summary
A remote machine manipulation system includes: a shooting unit that shoots an image of a remote machine that is remotely manipulated; and a visual presentation apparatus that receives the image shot by the shooting unit and presents an operator who manipulates the remote machine with the image by displaying the received image, the visual presentation apparatus including: a communication situation monitoring unit that detects a communication situation in the reception of the image; and a presented image control unit that determines a central field-of-view region and a peripheral field-of-view region in a display region in which the image is displayed and determines, on the basis of the communication situation detected by the communication situation monitoring unit, an image parameter related to a transmission rate of a central field-of-view image displayed in the central field-of-view region and a peripheral field-of-view image displayed in the peripheral field-of-view region.
