Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In manufacturing sites with paper-based operations, the long lead time for reporting work progress and difficulty in obtaining real-time status updates impede efficient personnel allocation and productivity, especially when using wearable terminals for data collection and analysis.
Innovation Solution
A work supporting apparatus that quickly and efficiently collects updated data files from wearable terminals by acquiring update dates, times, and positions, allowing for the specification of updated portions without full file acquisition, thereby reducing processing and communication loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wearable terminal performs processing involving a load intermittently, then the data file can be updated and stored locally, but operational delay of the terminal occurs
Solution Approach 1:
The patent extracts the heavy processing load from the wearable terminal and transfers it to a server. The terminal only performs lightweight operations such as generating hash values of data files and transmitting them, while the server handles the computationally intensive tasks of hash comparison, data synchronization, and analysis. This resolution allows the terminal to maintain real-time operational responsiveness while still achieving efficient data updates through server-side processing.
2Quantity of substance
If the data file capacity or number of terminals increases, then more work information can be collected, but the time taken to collect and analyze the file becomes longer
Solution Approach 1:
The patent extracts the time-consuming data collection and analysis operations from the wearable terminal and relocates them to a server. The terminal only needs to transmit data files when updated, while the server performs the actual collection from multiple terminals and conducts the analysis. This architectural separation enables the system to handle increasing data volumes and terminal quantities without proportionally increasing the time required for collection and analysis, as these operations are performed on the server's infrastructure.
Solution Approach 2:
The patent implements preliminary action by having the wearable terminal generate and store hash values of data files before actual data transmission. This allows the server to quickly identify which terminals have updated files by comparing hash values, eliminating the need to retrieve and analyze entire data files from all terminals. This preliminary hashing step significantly reduces the time required for data collection and analysis as the system scales.
3Ease of operation
If a wearable terminal of electronic paper is used to reduce burden on the worker, then the terminal can be made thin and lightweight with specialized reading and writing functions, but processing involving a load is performed on another computer via network
Solution Approach 1:
The patent introduces a server as an intermediary between the wearable terminal and the data analysis system. The lightweight terminal communicates with the server through simple network protocols, transmitting data files and receiving synchronization commands. The server acts as a mediator that handles all complex processing, storage, and analysis operations. This intermediary architecture allows the terminal to remain simple and lightweight while still achieving sophisticated data management capabilities through the server's computational power.

AI summary
A work supporting apparatus according to the present invention acquires, from a work terminal, an update date and time of a data file on the work terminal and a position on the data file currently displayed by the work terminal, and specifies an updated portion of the data file updated on the work terminal, based on the acquired update date and time and the acquired position on the data file.
