Solution Overview
Problem
Complexity in circuit diagrams of modern device systems, such as vehicles, ships, and machine tools, leads to increased wait times and user dissatisfaction due to the need for data restructuring and transmission over limited bandwidth networks, causing an incompatible feeling of system abnormality.
Innovation Solution
A circuit diagram supplying apparatus and method that requests and displays circuit diagram data in a structured manner, starting with part placement data and then sequentially transmitting and superimposing divided circuit diagram elements, reducing the need for extensive data reconstruction and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If circuit diagram data is transmitted in full form over network, then complete circuit diagram information is provided, but transmission time and data restructuring time increase significantly
Solution Approach 1:
The circuit diagram data is segmented into multiple transmission units based on display areas. Each transmission unit contains data for a specific display region, allowing incremental transmission and display. The display control unit receives and displays each segment as it arrives, superimposing them to reconstruct the complete circuit diagram progressively, thereby reducing overall wait time while maintaining information completeness.
2Loss of time
If circuit diagram data is divided into transmission units for network transmission, then transmission time is reduced, but data restructuring complexity increases
Solution Approach 1:
The circuit diagram data is pre-divided into transmission units corresponding to specific display areas before transmission. This preliminary segmentation eliminates the need for complex runtime restructuring, as each unit is already formatted for its intended display position. The display control unit simply needs to receive and superimpose the pre-segmented units, significantly reducing processing complexity.
3Speed
If all circuit diagram data is stored locally, then access speed is improved, but storage cost and system complexity increase
Solution Approach 1:
Instead of storing all circuit diagram data locally, the system stores only the essential display framework (part placement diagram) locally and retrieves detailed circuit diagram elements on-demand from the server. This selective local storage approach maintains fast access for critical structural information while minimizing storage requirements for comprehensive data.
4Quantity of substance
If data division and transmission method is used, then network bandwidth requirement is reduced, but display readiness time increases due to restructuring
Solution Approach 1:
The circuit diagram data is segmented into transmission units corresponding to display areas, enabling parallel reception and display of multiple segments. As each segment arrives, it is immediately displayed by superimposing on the part placement diagram, allowing the system to progressively build the complete circuit diagram without waiting for all data to arrive, thus maintaining fast display readiness while using limited bandwidth.

AI summary
A circuit diagram supplying apparatus 10, for supplying a user with whole contents of an device system circuit diagram, then requests a server 30 for first-of-all transmission of part-connection-drawing overall circuit diagram data in which connection diagrams LSd are added to a part placement diagram included in the circuit diagram and having electrical component parts PSd arranged therein. Then, after displaying a part-connection-drawing overall circuit diagram based on the transmitted and received part-connection-drawing overall circuit diagram data, the circuit diagram supplying apparatus 10 requests the server 30 for sequential transmission of circuit-element-drawing divisional circuit diagram data (a)-(e).
