Simultaneous Response Timing Offset for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional simultaneous response methods in electronic devices suffer from poor consistency due to network transmission delays and timer calculation errors, leading to inconsistent responses across devices, which negatively impacts user experience.
Innovation Solution
A method where a primary electronic device detects a response indication and sends instructions to secondary devices, considering the maximum time consumption for data transmission, allowing them to respond simultaneously without the need for network clock synchronization, thereby reducing errors and improving consistency.

Engineering Contradiction Analysis
1Reliability
If network clock synchronization is used for simultaneous response, then devices can obtain standard time, but network transmission delays cause different devices to receive standard time at different moments, resulting in poor simultaneous response consistency
Solution Approach 1:
The patent applies preliminary anti-action by pre-calculating and offsetting the network transmission delay before the simultaneous response occurs. The primary device measures the transmission time to each secondary device and subtracts this time from the target response time, thereby compensating for the delay in advance and ensuring all devices respond simultaneously despite network transmission variations.
Solution Approach 2:
The patent implements preliminary action by having the primary device pre-measure the transmission time to each secondary device before the actual simultaneous response event. This pre-measurement allows the system to calculate appropriate time offsets that will be applied when the response is triggered, ensuring synchronization without requiring real-time clock synchronization during the response event.
2Ease of operation
If each device sets its own timer based on received standard time, then devices can independently track time, but different devices set different clocks based on received standard time at different moments, causing timer expiration at different actual moments
Solution Approach 1:
The patent merges the time measurement and calculation function into a single primary device. Instead of each device independently measuring and calculating time offsets, the primary device performs the measurement and calculation centrally, then distributes the pre-calculated response instructions to all secondary devices. This eliminates discrepancies caused by independent measurements while maintaining the simplicity of local timer execution.
3Reliability
If network clock synchronization is implemented, then devices can obtain standard time, but this process introduces additional delay and complexity to the simultaneous response system
Solution Approach 1:
The patent extracts the clock synchronization requirement from the simultaneous response system. Instead of requiring devices to synchronize clocks through network time protocols, the system only requires the primary device to measure transmission time and calculate offsets. This separation eliminates the complexity of network clock synchronization while maintaining the ability to achieve simultaneous response through pre-calculated time offsets.

AI summary
A method for simultaneous response consistency and user experience includes, in response to detecting a response indication, a first electronic device that sends a response instruction to a second electronic device after a duration T−t1, and sends a response instruction to a third electronic device after a duration T−t2. The first electronic device performs a response operation after a target duration T, where T is greater than or equal to a maximum time consumption t, and t is a larger one of a first time consumption t1 between the first electronic device and the second electronic device and a second time consumption t2 between the first electronic device and the third electronic device. The second electronic device and the third electronic device each performs a response operation in response to receiving the response instruction.
