Solution Overview

Problem

Existing board work devices fail to notify operators of errors when the power source is switched off, as they cannot display information in such scenarios, limiting the operator's ability to address the issue.

Innovation Solution

Incorporating error information reception, storage, and notification mechanisms within the board work system to detect and notify operators of power source failures in other devices, even when their power is off, through communication state or trigger signal detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the power source of a board work device is switched off to cope with an error, then the device can be protected from further damage or malfunction, but the device cannot display error information on its own display panel

Engineering Contradiction:
Improveerror handling capabilityVSAvoiderror information display
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces another board work device as an intermediary to display error information. When device A encounters an error and switches off its power source, device B (another board work device in the system) receives the error information via communication means and displays it on its display panel. This mediator approach allows error information to be preserved and displayed even when the original device cannot display it.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary action by having board work devices continuously monitor communication status and detect power source states of other devices before errors occur. The notification mechanism is pre-established through communication means, so when a device switches off its power due to an error, the information is already available at another device ready for immediate display.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If multiple board work devices are connected in a network to enable information sharing, then error information can be notified to operators even when one device is powered off, but the system complexity increases

Engineering Contradiction:
Improveerror information notificationVSAvoidcommunication infrastructure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies universality by making each board work device capable of multiple functions: not only performing its primary board work tasks but also serving as both an error information source and a potential error information display device. Each device is equipped with communication means that enables it to both send and receive error information, making the entire system universally capable of error notification without requiring dedicated monitoring devices.

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

AI summary

In a board work system 10, the CPU 32 of a board work device 20 transmits error related information which relates to an error in a case where the error has occurred in the own device. Then, the CPU 32 receives the error related information which relates to the error of the other board work device 20, and stores the received error related information in the HDD 35. Then, the display operation section 60 is controlled such that information (other device error notification screen) based on the stored error related information is notified to the operator in a case where the power source of the board work device 20 (other board work device 20), in which the error has occurred, is detected to be switched off. Thereby, it is possible for the other board work device 20 to notify information which relates to the error to the operator in a case where the power source of the other board work device 20, in which the error has occurred, is switched off.
