Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current failure diagnosis systems require complex operations and extensive information retrieval, making it difficult for workers to efficiently diagnose failures in complex apparatuses like tractors.
Innovation Solution
A failure diagnosis assisting device that displays a circuit diagram and incorporates design information, allowing workers to select components or connection terminals to view diagnosis-assisting diagrams, including parts arrangement and pin arrangement diagrams, and maintenance procedures, using element IDs for easy information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If design information is incorporated into circuit diagram information, then information retrieval efficiency is improved, but information storage complexity increases
Solution Approach 1:
The patent combines circuit diagram information and design information into a single integrated data structure. The circuit diagram information includes not only graphical representation data but also embedded design information such as part numbers, specifications, and connection details, eliminating the need for separate information retrieval processes.
Solution Approach 2:
The circuit diagram information serves multiple functions simultaneously: it provides visual circuit representation, contains searchable design information, enables component identification, and supports diagnosis operations. This multi-functionality reduces the need for separate information systems and improves retrieval efficiency.
2Measurement precision
If manual input of component names is required, then information accuracy is improved, but operation complexity increases
Solution Approach 1:
The system performs automatic component identification by detecting which component the user is viewing or has selected on the circuit diagram. The diagnosis assisting diagram automatically updates based on the current component focus, eliminating the need for manual typing of component names while maintaining accurate identification through cursor position or selection state detection.
Solution Approach 2:
The patent replaces manual typing operations with graphical interface interactions. Users can simply click on or hover over components in the circuit diagram, and the system automatically retrieves and displays the corresponding design information, substituting mechanical keyboard input with more intuitive graphical selection methods.
3Measurement precision
If detailed design information is displayed, then diagnosis accuracy is improved, but display area requirements increase
Solution Approach 1:
The patent divides the display into multiple functional areas: the circuit diagram occupies the main display area, while design information is presented in a separate, collapsible panel or overlay. This segmentation allows detailed information to be displayed without obscuring the circuit diagram, and users can adjust the amount of information visible based on their diagnostic needs.
Solution Approach 2:
The system uses layered or popup display mechanisms where detailed design information appears in floating windows or side panels that do not permanently occupy main display space. This creates a multi-dimensional display structure where information can be accessed without permanently reducing the circuit diagram visibility area.
