Work Machine Performance Server for Consistent Load Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the construction industry, workers face inefficiencies when creating work plans for work machines like cranes, as they need to refer to cumbersome rated total load tables to obtain performance information, leading to poor work efficiency and potential discrepancies in performance data between similar work machines.
Innovation Solution
A performance information server system that includes a request acquisition unit, a storage unit, a control unit, and a response presentation unit to efficiently acquire and provide performance information of work machines based on model information and specification data, allowing clients and work machines to connect and retrieve necessary performance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If workers refer to rated total load tables to obtain performance information, then they can get performance data, but work efficiency deteriorates due to cumbersome procedures
Solution Approach 1:
The patent replaces the manual mechanical process of referring to physical rated total load tables with an automated information system. The server stores performance information and automatically retrieves it based on work machine identification, eliminating the need for workers to manually search through tables and significantly improving work efficiency.
Solution Approach 2:
The patent introduces a performance information server as an intermediary between the rated total load tables and the workers. This server acts as a mediator that automatically processes information requests, retrieves relevant performance data based on work machine IDs, and provides it to workers, thereby eliminating the cumbersome manual table-reading process.
2Reliability
If arithmetic expressions are updated for each work machine by maintenance workers, then performance information can be calculated, but consistency deteriorates due to potential differences in updates
Solution Approach 1:
The patent merges the scattered arithmetic expressions stored in individual work machines into a single centralized server. This consolidation ensures that all work machines of the same type access the same updated arithmetic expressions and specification data from the server, eliminating inconsistencies that arise from individual updates by maintenance workers.
Solution Approach 2:
The server provides universal access to updated arithmetic expressions and specification data for all work machines. Instead of each machine having its own separate update process, the server serves as a universal source that automatically provides consistent, up-to-date calculation data to any work machine that connects to it, ensuring data consistency across the entire fleet.
3Stability of the object's composition
If performance information is stored in a centralized server, then data consistency is improved, but system complexity increases
Solution Approach 1:
The patent uses the performance information server as an intermediary that provides data consistency without requiring complex changes to work machines. The server handles all complexity of data storage, arithmetic expression management, and specification data maintenance, while work machines remain simple clients that only need to send requests and receive responses, thereby maintaining simplicity at the machine level.
Solution Approach 2:
The server automatically manages arithmetic expression updates and specification data maintenance without requiring manual intervention from maintenance workers for each machine. The system self-services by centrally storing and automatically providing updated data to all connected work machines, reducing the operational complexity despite the added infrastructure.

AI summary
A performance information server comprises: a request acquisition unit that acquires a request including machine-type information for a work machine, and a performance information request to indicate performance information for the work machine; a storage unit that stores specification data for the work machine in association with the type of the work machine; a control unit that acquires the machine type information included in the request and the performance information for the work machine, on the basis of the specification data corresponding to the machine type information; and a response presentation unit that presents a response including the performance information acquired by the control unit.
