Molding Management System Threshold Update Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In molding processes, users often inadvertently change defect threshold values beyond acceptable limits, leading to delayed detection of molding defects due to the lack of clear differentiation between non-defective and defective product criteria, resulting in increased production of defective products.
Innovation Solution
A molding management system that includes a storage unit for correlated information about molded products, standard values, and threshold values, along with a screen generating and display unit, allowing users to update threshold values while ensuring they do not exceed standard values, thereby preventing incorrect defect determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the threshold value is made editable to allow flexible defect detection, then the ease of operation is improved, but the risk of erroneous changes increasing production of defective products
Solution Approach 1:
The system provides real-time feedback by displaying the standard value alongside the threshold value during editing. When a user attempts to change the threshold, the system compares the new value against the standard value and provides visual feedback (through the displayed relationship between threshold and standard value) to prevent erroneous changes that would increase defective product production.
Solution Approach 2:
The system performs preliminary action by displaying the standard value before the user completes the threshold edit. This allows the user to review the standard value and make an informed decision about the threshold change, preventing erroneous modifications that would compromise defect determination reliability.
2Ease of operation
If the threshold value is displayed separately from the standard value, then the ease of operation is improved, but the measurement precision of defect detection deteriorates
Solution Approach 1:
The system merges the display of the threshold value and the standard value into a single interface element. The threshold value is displayed with an indication of its relationship to the standard value, allowing users to easily set the threshold while maintaining clear context about the standard for accurate defect detection.
Solution Approach 2:
The system uses the standard value as an intermediary reference that is always visible during threshold editing. This intermediary element provides contextual information that helps users understand the relationship between the threshold and standard values, ensuring precise defect detection while maintaining ease of operation.
3Adaptability or versatility
If the threshold value can be changed without constraints, then the adaptability is improved, but the manufacturing precision of defect criteria deteriorates
Solution Approach 1:
The system allows parameter changes in the threshold value while maintaining a relationship to the standard value. The threshold can be adjusted adaptively based on production needs, but the system ensures that the change maintains manufacturing precision by displaying the standard value and preventing changes that would compromise the defect criteria.

AI summary
A molding management system includes a storage unit configured to store, in correlation, information concerning an item of a molded product, information concerning a standard value, which is a value concerning a specification of the molded product, and information concerning a threshold, which is a value used to determine a sign of a defect of the molded product, a screen generating unit configured to generate a screen; and a display unit configured to display the screen. The information concerning the item of the molded product and the information concerning the standard value of the molded product are displayed on the screen. A first region for enabling update of the information concerning the threshold of the molded product is provided on the screen.
