Clock Signal Periodic Pattern for Reliable Serial Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems using serial interfaces become unreliable due to stringent requirements for control data transmission, leading to short time slots that are insufficient for reliable data transmission and feedback in electric devices.
Innovation Solution
A method and apparatus that transmit a clock signal with a periodic elementary pattern to devices, allowing for the extraction of information from asynchronous signals, and utilize multiple signal paths with varying lengths and a selector to improve data transmission efficiency by aligning signal paths with periodic timing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional serial interface control is used with stringent transmission requirements, then control data transmission frequency increases, but time slots for individual control signals become too short for reliable transmission
Solution Approach 1:
The patent applies periodic action by using a clock signal with a periodic elementary pattern that repeats across multiple cycles. This periodic structure allows the system to maintain higher transmission frequencies while ensuring reliable detection by providing multiple opportunities (cycles) for the receiving device to correctly identify control signal transitions, thereby resolving the contradiction between transmission frequency and reliability
2Reliability
If time slots for control signals are extended to improve reliability, then accidental timing errors are reduced, but data throughput decreases
Solution Approach 1:
The patent segments the clock signal into multiple cycles within the periodic elementary pattern, with each cycle providing a segmented opportunity for control signal detection. This segmentation allows the system to extend the effective detection window across multiple cycles rather than requiring a single extended time slot, thereby maintaining reliability while preserving higher data throughput capability
Solution Approach 2:
The periodic elementary pattern provides continuous useful action by maintaining the clock signal operation across multiple cycles without interruption. This continuity ensures that control signal detection can occur at any cycle, preventing loss of data throughput while maintaining reliability through repeated detection opportunities
3Measurement precision
If multiple signal paths with varying lengths are used to align signals with periodic timing elements, then timing accuracy improves, but device complexity increases
Solution Approach 1:
The patent changes the physical parameter of signal path length to achieve timing alignment. By providing multiple signal paths with different lengths and allowing selection based on timing requirements, the system achieves precise timing synchronization with the periodic clock signal while managing complexity through parameter variation rather than structural complexity
