Synchronous Pulse Start-Time Adjustment for Phase-Aligned Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing synchronous communication systems face challenges in synchronizing newly added synchronous communication apparatuses, as setting a new start time can result in phase shifts, leading to the inability to output synchronized pulses, necessitating a re-synchronization of all apparatuses.
Innovation Solution
A synchronous communication apparatus is equipped with an output unit, generation unit, and change unit to adjust the set time for generating synchronous pulses, ensuring it is later than the current time if necessary, allowing seamless synchronization with other apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new synchronous communication apparatus is added to the system with a newly set start time, then the apparatus can be integrated into the system, but the phase of the synchronous pulse becomes shifted relative to existing apparatuses, preventing synchronized pulse output
Solution Approach 1:
The change unit proactively adjusts the start time before the apparatus attempts to output synchronous pulses. By detecting that the current time is later than the set start time and automatically modifying the start time to a future time point, the system prevents phase shifts before they occur, ensuring reliable synchronization when the apparatus joins the network
Solution Approach 2:
The start time parameter is made dynamic rather than fixed. The change unit continuously monitors the relationship between the current time and the set start time, and automatically adjusts the start time based on real-time conditions. This dynamic adjustment allows the system to adapt to time variations and maintain synchronization accuracy across all apparatuses
2Speed
If the start time is set to a past time to enable immediate pulse output, then the apparatus can output pulses without waiting, but the phase becomes shifted relative to other apparatuses that started at their respective start times
Solution Approach 1:
Instead of allowing immediate output at past times which causes phase shifts, the change unit proactively adjusts the start time to a future time point. This preliminary correction ensures that when the apparatus does output pulses, they will be in the correct phase relationship with other apparatuses, sacrificing immediate output capability to maintain synchronization reliability
3Reliability
If all synchronous communication apparatuses perform re-synchronization when a new apparatus is added, then phase alignment can be restored, but the system efficiency decreases due to redundant synchronization operations
Solution Approach 1:
The invention extracts and isolates the time adjustment function into a dedicated change unit that operates independently on each apparatus. This localized adjustment mechanism allows individual apparatuses to correct their start times without requiring coordinated re-synchronization operations across the entire system, thereby maintaining phase alignment while improving overall system efficiency
Solution Approach 2:
Each synchronous communication apparatus has the capability to self-adjust its start time through the change unit. When a new apparatus joins the system, it automatically detects the time relationship and independently modifies its own start time parameter, eliminating the need for other apparatuses to perform re-synchronization operations and reducing system-wide complexity

AI summary
A synchronous communication apparatus includes an output unit configured to output a current time for synchronizing with another communication apparatus, a generation unit configured to generate a synchronous pulse at a predetermined frequency, and a change unit configured to, if a set time that is set as a time at which the generation unit starts generation of the synchronous pulse is not a time later than the current time, change the set time to a time later than the current time.
