Engineering Contradiction Analysis
1Productivity
If the data report rate of the peripheral device is increased to improve operating accuracy and smoothness, then the data transmission frequency is improved, but the workload of the computer host increases and power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of the data report rate based on real-time monitoring of hardware operation information and workload levels. The system transitions from a static high report rate to a dynamically adjustable rate that adapts to current system conditions, resolving the contradiction between maintaining high productivity and reducing power consumption.
Solution Approach 2:
The patent changes the parameter of data report rate from a fixed value to a variable that can be adjusted based on monitoring thresholds and workload conditions. By modifying this key parameter dynamically, the system achieves both high data transmission frequency when needed and reduced workload when conditions permit.
2Productivity
If the data report rate is increased to improve operating accuracy and smoothness, then the data transmission frequency is improved, but the computer host may be unable to meet the high data report rate requirement
Solution Approach 1:
The patent implements a feedback mechanism where the computer host monitors hardware operation information and workload levels, then adjusts the data report rate accordingly. This closed-loop control ensures that the system maintains reliable operation by preventing the host from being overwhelmed while still achieving high data transmission frequencies when capable.
Solution Approach 2:
The system dynamically adjusts the data report rate based on real-time monitoring of host capacity and workload conditions. This dynamic adaptation ensures reliability by matching the data transmission rate to the host's actual ability to process it, preventing system overload and data loss.
3Productivity
If the peripheral device operates at high data report rate to improve accuracy and smoothness, then the data transmission frequency is improved, but power consumption increases
Solution Approach 1:
The patent changes the operating parameter of the peripheral device from a fixed high report rate to a dynamically adjustable rate. By modifying this parameter based on actual needs and host capacity, the system reduces unnecessary power consumption while maintaining adequate data transmission frequency for accurate and smooth operation.

AI summary
A data report rate adjustment method for use between a computer host and a peripheral device is provided. According to the actual workload level of the computer host and/or the amount of the input data of the peripheral device, the priority or the report rate of the data to be transmitted from the peripheral device can be dynamically adjusted or set. More especially, the unnecessary data report can be avoided. Consequently, the workload of the computer host can be effectively reduced, and the power consumption of the peripheral device can be saved.
