Electronic Device Data Access Distribution via Probability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems with a large number of client devices, the server device and communication line experience high loads due to concentrated data access, especially on non-work days or holidays, as client devices typically do not access the server on these days, leading to potential data download congestion.
Innovation Solution
A client device with a control device that cyclically checks for new data and determines, based on a probability, whether to download it immediately or postpone the download, thereby reducing the load on the server and communication line by spreading access and download operations across different days.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If client devices are set to access the server device on a predetermined day of the week to temporally distribute access, then access distribution is improved, but load concentration occurs on the first work day after consecutive non-work days
Solution Approach 1:
The patent applies dynamics by making the access day flexible rather than fixed. Each client device randomly determines its access day within a range that excludes non-work days, allowing the system to adapt to varying work schedules and holidays. This dynamic adjustment prevents load concentration on specific days while maintaining effective load distribution across the server device and communication line.
2Ease of operation
If client devices access the server device only on work days, then ease of operation is improved, but load concentration on the server device and communication line increases due to holidays and non-work days
Solution Approach 1:
The patent changes the parameter of access day from a fixed predetermined day to a randomly determined day within a flexible range. This parameter change allows client devices to avoid non-work days and holidays while distributing access across multiple days, thereby reducing load concentration on the server device and communication line without compromising ease of operation.
3Productivity
If data download is concentrated on specific days, then productivity is improved through efficient data transfer, but the server device and communication line experience excessive load
Solution Approach 1:
The patent segments the data download process by having each client device independently determine its own access and download day within a random range. This segmentation distributes the overall download load across multiple days and devices, preventing excessive concentration on the server device and communication line while maintaining productive data transfer through efficient individual downloads.

AI summary
An electronic device includes: a communication device configured to communicate with a server device that provides data; a storage device; and a control device that cyclically accesses the server device using the communication device to check whether or not new data has been provided from the server device, determines, based on a predetermined probability, whether to download the new data from the server device or to postpone download when the new data has been provided, and stores, in the storage device, the new data downloaded from the server device.
