Solution Overview

Problem

Existing methods for producing electronic components do not adequately specify production information, making it difficult to determine whether abnormalities in the production system have occurred during component use.

Innovation Solution

A production method for electronic components that includes attaching a unique identifier to each component, allowing for the storage and retrieval of production information such as inspection results and system states, enabling precise tracking of production processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a unique identifier system is implemented to track production information, then the ability to specify production information is improved, but the device complexity increases

Engineering Contradiction:
Improveproduction informationVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses printed data (copies of production information) on the electronic component itself to represent and transmit production information through multiple inspection processes, eliminating the need for complex centralized tracking systems

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces printed data as an intermediary carrier that bridges communication between different inspection processes, allowing production information to be transmitted without direct system integration

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple inspection processes are implemented to ensure quality, then the measurement precision is improved, but the productivity decreases

Engineering Contradiction:
Improveinspection accuracyVSAvoidmanufacturing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent enables continuous inspection processes by having each inspection process read printed data from the component itself, eliminating stopping and starting between inspections, thereby maintaining production flow while ensuring quality

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent performs marking with production information before inspection processes, so that subsequent inspections can quickly read and verify information without needing to perform complex measurements or re-testing

Inventive Principle:
Principle #10Preliminary action

AI summary

An electronic component (for example, an electrolytic capacitor) includes an internal element (for example, a capacitor element) and a packaging (for example, a case). The production lot for the internal element includes a plurality of subunits. The packaging is provided with an identifier for identifying the plurality of subunits. By this configuration, it is possible to provide an electronic component capable of specifying production information, a production method for the electronic component, a management method for the electronic component, and a program. The identifier may be provided on the packaging as a display. Further, the identifier may be a one-dimensional code or a two-dimensional code.
