Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high bandwidth sensor data is transmitted continuously over wireless networks, then data resolution is improved, but latency increases and network reliability deteriorates
Solution Approach 1:
The system dynamically adjusts the resolution of sensor data transmission based on real-time network conditions. The remote computing device monitors network bandwidth availability and adaptively modifies data resolution parameters to optimize the balance between data quality and transmission latency, ensuring high resolution when bandwidth is abundant and reduced resolution when bandwidth is constrained.
Solution Approach 2:
The patent changes the resolution parameter of sensor data streams based on network conditions. By adjusting data resolution (a key parameter), the system can transmit either high-resolution data when network bandwidth is sufficient or lower-resolution data when bandwidth is limited, thereby controlling latency while maintaining acceptable data quality.
2Productivity
If data transmission rate is increased to maximize throughput, then productivity is improved, but network reliability and latency performance worsen
Solution Approach 1:
The system implements feedback control by continuously monitoring network performance metrics (bandwidth availability, latency, packet loss) and using this information to adjust the data transmission rate. The control computing device sends feedback to the remote computing device about current network conditions, which triggers adaptive adjustments in data resolution and transmission rate to maintain both high throughput and reliable latency performance.
Solution Approach 2:
The transmission system dynamically adapts its operating parameters based on real-time network conditions. Rather than using a fixed transmission rate, the system continuously adjusts data resolution and throughput levels to match available network bandwidth, maximizing productivity when conditions permit while ensuring reliability when network resources are constrained.
3Ease of operation
If wireless network is used to eliminate wired infrastructure, then ease of operation and mobility are improved, but network bandwidth and reliability deteriorate
Solution Approach 1:
The system compensates for limited wireless network bandwidth by dynamically changing data transmission parameters. When network bandwidth is constrained (as is typical in wireless environments), the system automatically adjusts sensor data resolution and transmission rates to ensure efficient use of available bandwidth while maintaining acceptable data quality and minimizing latency.
Solution Approach 2:
The patent implements a dynamic transmission system that adapts to the variable bandwidth characteristics of wireless networks. The system continuously monitors network conditions and adjusts its operation accordingly, enabling mobile and flexible deployment while optimizing data transmission efficiency given the constraints of wireless network resources.

AI summary
Disclosed is a method and apparatus to continuously transmit high bandwidth, real-time data, on a communications network (e.g., wired, wireless, and a combination of wired and wireless segments). A control computing device uses user or application requirements to dynamically adjust the throughput of the system to match the bandwidth of the communications network being used, so that data latency is minimized. An operator can visualize the instantaneous characteristic of the link and, if necessary, make a tradeoff between the latency and resolution of the data to help maintain the real-time nature of the system and better utilize the available network resources. Automated control strategies have also been implemented into the system to enable dynamic adjustments of the system throughput to minimize latency while maximizing data resolution. Several applications have been cited in which latency minimization techniques can be employed for enhanced dynamic performance.
