Time Recording Device Local Memory Group-Based Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time and attendance recording systems face challenges in reducing waiting times and resource/energy usage, especially during peak hours, due to high demands on data handling and increasing remote work scenarios.
Innovation Solution
A time and presence recording device with local memory and a communication interface, where personal data is stored based on group assignment, reducing data traffic and latency by storing data locally for frequent users and retrieving it from the server only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal data is stored centrally on the server system, then data protection and centralized management are improved, but waiting times and latency during user interactions increase especially during peak times
Solution Approach 1:
The patent segments the centralized storage system into distributed local storage units. Personal data is divided and stored across multiple time recording devices locally, rather than being concentrated on a single server. This segmentation allows users to access data from local storage immediately, reducing waiting times while maintaining data protection through distributed security measures.
Solution Approach 2:
The patent implements preliminary action by pre-loading personal data into local storage of time recording devices before users need to access it. Data is fetched and cached in advance during off-peak times or when connectivity is available, so that during peak usage periods, users experience minimal to no waiting time as data is already locally available.
2Loss of time
If personal data is stored locally on the time recording device, then waiting times and latency are reduced, but data traffic and resource usage on the server system increase
Solution Approach 1:
The patent applies local quality by making storage capacity and data caching behavior specific to each individual time recording device. Each device independently manages its own local storage, caching personal data based on local usage patterns and availability. This distributed approach reduces overall server resource usage while maintaining fast local access, as each device operates autonomously with its own storage resources.
Solution Approach 2:
The patent implements partial action by selectively storing only necessary personal data locally on time recording devices rather than caching everything. The system determines which data should be stored locally based on access frequency and user needs, performing partial local storage that reduces server traffic without requiring excessive local storage resources on each device.
3Speed
If personal data is stored locally for all users, then access speed is improved, but storage capacity requirements and device complexity increase
Solution Approach 1:
The patent applies universality by designing the time recording device to perform multiple functions: it acts as both a data collection point and a local storage/cache system. The device's communication interface and processing unit are multi-functional, handling both real-time data capture and local data management. This reduces device complexity compared to dedicated storage systems, as existing components serve dual purposes.
Solution Approach 2:
The patent uses copying by creating local replicas of personal data on time recording devices rather than storing original data everywhere. Instead of duplicating entire data sets, the system creates selective copies of frequently accessed personal data in local storage. This copying approach maintains fast access speeds while minimizing storage capacity requirements and managing device complexity through intelligent replication strategies.
