Printed Sheet Inspection Area Planning Under Time Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems struggle to complete inspections on printed sheets within a limited time frame, especially when multiple areas need to be inspected, leading to difficulties in distinguishing defective sheets from normal ones.
Innovation Solution
An inspection apparatus with a display and controllers that set inspection areas, perform data inspections, and display data limits graphically, allowing for efficient recognition of inspection upper limits and values, thereby enabling timely differentiation between defective and normal sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of areas to be inspected are set in the printing system, then the inspection coverage is improved, but the inspection processing time increases making it difficult to complete within the time limit
Solution Approach 1:
The system performs preliminary calculations of inspection processing time for each area to be inspected, and displays these time values to the user before actual inspection begins. This allows users to understand the time consumption of each inspection area in advance and make informed decisions about area selection to ensure completion within the time limit.
Solution Approach 2:
The system provides feedback to the user by displaying the calculated inspection processing time for each area and the remaining time after selecting areas. This feedback mechanism enables users to adjust their area selections dynamically to ensure the total inspection can be completed within the available time limit.
2Productivity
If multiple areas are inspected within the limited time, then the productivity is improved, but the accuracy of distinguishing defective sheets deteriorates due to rushed processing
Solution Approach 1:
The system calculates and displays the processing time required for each area before inspection begins, allowing users to plan their area selections in advance. This preliminary time assessment ensures that even when inspecting multiple areas quickly, the system can complete the inspection accurately within the time limit.
Solution Approach 2:
The system dynamically updates the display of remaining time and inspected areas as the inspection progresses. This dynamic feedback allows the system to adapt to the actual inspection speed and ensure that sufficient time is allocated for accurate defect detection even when multiple areas are being inspected.
Data Source
AI summary
An inspection apparatus includes a display control unit configured to display information on a display unit, a setting unit configured to set one or more areas including an object to be inspected, and an inspection unit configured to inspect data read from the object included in the one or more areas set by the setting unit. The display control unit displays a graphic to enable recognition of an upper limit of data to be inspected by the inspection apparatus. When the setting unit sets one or more areas, the display control unit displays values based on an amount of data on the object included in the one or more areas set by the setting unit as a graph.
