Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to exchange data between devices, then wired connection is eliminated and flexibility is improved, but delay time increases and response speed deteriorates
Solution Approach 1:
The patent dynamically adjusts encoding parameters (such as compression ratio, resolution, frame rate) based on measured delay times and network conditions. By changing these parameters, the system optimizes the balance between data transmission quality and delay time, resolving the contradiction between wireless flexibility and response speed.
Solution Approach 2:
The system implements a feedback mechanism where delay time is continuously measured and used to adjust encoding parameters. The delay measurement unit monitors the actual delay, and this information feeds back to the encoding parameter adjustment unit, creating a closed-loop control system that adapts to changing conditions and minimizes delay while maintaining wireless operation.
2Speed
If encoding parameters are adjusted to reduce delay time, then response speed is improved, but data quality may deteriorate
Solution Approach 1:
The encoding parameters are made dynamic rather than fixed. The system continuously adapts encoding settings based on real-time delay measurements and application requirements. This dynamic adjustment allows the system to optimize for speed when delay is critical while maintaining quality when conditions permit, resolving the static trade-off between response speed and data quality.
Solution Approach 2:
Multiple encoding parameters (compression ratio, resolution, bit rate) are adjusted in coordination based on measured delay times. The system selects optimal parameter combinations that achieve acceptable delay reduction while maintaining sufficient data quality for the specific application, rather than simply reducing quality to speed up transmission.
3Loss of time
If delay time measurement and parameter adjustment mechanisms are added, then delay optimization is achieved, but device complexity increases
Solution Approach 1:
The patent integrates delay measurement and parameter adjustment functions into existing wireless communication components. The encoding unit serves multiple purposes: both compressing data and adapting to delay constraints. The control unit coordinates multiple functions (encoding, transmission, delay measurement) rather than adding separate dedicated systems, reducing overall complexity while achieving delay optimization.
Solution Approach 2:
The delay measurement unit and encoding parameter adjustment unit are integrated into the existing wireless communication architecture. Rather than adding completely separate systems, the patent combines these functions with existing data processing and transmission components, sharing hardware and software resources to minimize the increase in device complexity.

AI summary
A first device for processing data, the first device including at least one control circuit configured to adjust at least one parameter related to a delay time based on a measured value of the delay time. The measured value of the delay time is a difference between a first time associated with when the first device processes the data and a second time associated with when a second device processes the data.
