Solution Overview

Problem

Existing display systems in component mounting lines do not effectively guide users through current and upcoming operations, leading to potential distractions and inefficiencies.

Innovation Solution

A display device with a control section that sequentially guides users through current and upcoming operations by displaying images on a process-by-process basis, adjusting content visibility based on operation start times, and prioritizing tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a list of all component feeders with component shortage time is displayed, then the user can see all upcoming tasks, but the user cannot focus on the current process and may be distracted by future tasks

Engineering Contradiction:

Improveinformation about upcoming tasksVSAvoiduser focus on current process

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The display is segmented into multiple regions: a first display region showing the current process information and a second display region showing upcoming process information. This segmentation allows the system to present comprehensive task information while maintaining user focus on the current process by spatially separating current and future tasks.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If only current process information is displayed, then the user can focus on the current task, but the user cannot easily know what process to execute next

Engineering Contradiction:

Improveuser focus on current processVSAvoidtime to understand next process

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by displaying information about the next process in advance in the second display region, before the user actually needs to execute it. This allows the user to mentally prepare for the upcoming task while still focusing on the current process, reducing the time needed to transition between tasks.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If detailed information about multiple future processes is displayed simultaneously, then the user can plan ahead, but the display becomes complex and overwhelming

Engineering Contradiction:

Improvetime to prepare for next processVSAvoiddisplay information organization

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system extracts only the essential information about upcoming processes (process name and timing) and displays it separately in the second display region, rather than showing all detailed information simultaneously. This extraction approach provides advance notice without overwhelming the user with excessive details.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Different regions of the display have different information densities and levels of detail. The first display region dedicated to the current process provides comprehensive information, while the second display region provides concise overview information about upcoming processes. This local quality variation optimizes information presentation for different user needs.

Inventive Principle:

Principle #3Local quality

AI summary

A display device includes a display section and a control section, and displays an operation to be executed by a user in a component mounting line on a process-by-process basis on the display section. The control section is configured to, when a first image illustrating a content of a first process to be currently executed by the user is being displayed on the display section and when there exists a second process to be executed by the user after the first process, display a second image for guiding the second process on the display section along with the first image.
