Solution Overview

Problem

Conventional CAD systems for printed circuit board design are limited in handling electric information across multiple objects, requiring manual visual observation and input/output listing, which is error-prone and inefficient.

Innovation Solution

An electric information processing method and system that automates the handling of electric information between objects using a CPU-controlled unit with a database and user input devices, allowing for automated processing and display of signal and circuit data across multiple substrate blocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional printed circuit board CAD systems are used, then design work can be performed for single printed circuit board, but electric information with other related printed circuit boards or other objects cannot be handled

Engineering Contradiction:
Improvehandling range of electric informationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The CAD system is enhanced to handle electric information not only for single printed circuit boards but also for multiple related printed circuit boards and other electronic objects. The system introduces a hierarchical data structure where electric information is managed at both object level and system level, enabling universal handling across different objects while maintaining a unified management framework.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements a nested data structure where electric information of individual objects is contained within object-level data structures, which are in turn nested within system-level data structures. This hierarchical nesting allows the system to manage electric information at multiple levels of abstraction simultaneously, from individual component level to overall system level.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If manual visual observation and listing of input/output information is performed, then electric information can be considered, but the work is very troublesome and errors can easily occur

Engineering Contradiction:
Improveerror rateVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically generates and manages electric information data structures without requiring manual intervention. The CAD system self-services by automatically extracting electric information from circuit designs, generating input/output information lists, and maintaining data consistency across multiple objects, thereby eliminating manual visual observation and reducing error-prone operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements automated feedback mechanisms where electric information is continuously tracked and verified across object boundaries. The system automatically checks for consistency in electric information flow between related printed circuit boards and objects, providing real-time feedback to detect and prevent errors without manual intervention.

Inventive Principle:
Principle #23Feedback

3Productivity

If conventional CAD systems handle only single object information, then system simplicity is maintained, but design efficiency for complex electronic products deteriorates

Engineering Contradiction:
Improvedesign work efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments electric information management into distinct hierarchical levels: object-level electric information structures and system-level electric information structures. This segmentation allows the system to handle complex multi-object electric information relationships while maintaining manageable complexity at each level, thereby improving design efficiency for complex electronic products without overwhelming system complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

It is possible to improve workability of a design work by handling electric information between one object and other objects associated with the object. A plurality of objects are inputted and electric information is inputted to the objects. Among the objects, mutually connected objects are virtually made into a single object. According to electric information in each of the objects, i.e., the virtually unified single object and the other objects excluding the virtually unified single object, objects having the common electric information are connected by straight lines. According to the straight lines, a figure connecting the objects is inputted. A condition for connecting the objects in the figure is inputted. According to the condition, circuit parts are built and signal information is set in a terminal of the circuit parts.
