Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-channel data transmission systems face challenges in determining the correct control signal type due to errors in synchronization signals under poor transmission quality, leading to potential mistakes in data reading and degraded system robustness when fixed priorities are used without considering varying time periods.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed priority is used to select control signals when multiple types have the same amount, then the selection process is simple and fast, but system robustness and consistency are degraded
Solution Approach 1:
The patent applies dynamics by transitioning from a static fixed priority system to a dynamic priority system that adapts based on channel accuracy evaluations. The control signal selection priority is no longer fixed but changes according to the evaluated accuracy of different channels, allowing the system to respond to varying transmission conditions and maintain both speed and reliability.
Solution Approach 2:
The patent changes the parameter of control signal selection priority from a fixed value to a variable value that depends on channel accuracy evaluation results. By introducing channel accuracy as a new parameter that influences priority selection, the system can make more informed decisions about which control signals to adopt, improving robustness while maintaining efficient operation.
2Reliability
If decision by majority is applied to select control signals, then the system can handle errors in synchronization signals, but inconsistencies occur when multiple control signal types have the same amount
Solution Approach 1:
The patent implements feedback by evaluating channel accuracy and using these evaluation results to influence control signal selection. The system continuously monitors the transmission quality and adjusts its selection criteria based on feedback from accuracy evaluations, ensuring consistent and reliable control signal adoption even when multiple types have equal distribution.
Solution Approach 2:
The patent applies preliminary action by performing channel accuracy evaluations before making control signal selection decisions. This preliminary assessment of channel conditions allows the system to prepare appropriate selection strategies in advance, preventing inconsistent decisions from occurring when multiple control signal types have the same amount.
3Ease of manufacture
If conventional multi-channel system uses fixed priority for control signal selection, then the implementation is straightforward, but system robustness is degraded under varying transmission conditions
Solution Approach 1:
The patent transforms the static fixed priority mechanism into a dynamic system that adapts to varying transmission conditions. By introducing channel accuracy evaluation and using these results to adjust selection priorities, the system maintains implementation feasibility while significantly improving robustness under different transmission quality conditions.
Solution Approach 2:
The patent changes the selection priority parameter from a fixed constant to a variable that reflects actual channel conditions. This parameter change allows the system to maintain simplicity in implementation while achieving superior robustness, as the priority values are determined by evaluating channel accuracy rather than being hard-coded.
