Print Quality Control via Tolerable Variation Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current product quality request and reporting systems in commercial printing fail to ensure consistency and uniformity, particularly in large-scale production of printed products, as variations in quality, such as color differences and misregistration, can lead to products standing out and compromising display consistency when mixed with products of constant quality.
Innovation Solution
A system comprising first and second information processing apparatuses that receive and transmit quality request data, including tolerable variations, to determine if printed products meet quality standards, ensuring that products within tolerable ranges are considered consistent and uniform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If higher quality standards are applied to printed products, then product quality is improved, but quality uniformity among products deteriorates
Solution Approach 1:
The patent changes the parameter of quality evaluation from absolute quality metrics to relative variation metrics. By setting tolerable variation ranges for quality differences among products, the system allows individual products to have different quality levels while maintaining overall uniformity. This resolves the contradiction by transforming the quality control approach from maximizing individual product quality to controlling the distribution and variation of quality across the product batch.
2Reliability
If quality requirements are strictly enforced, then product quality is improved, but product consistency deteriorates
Solution Approach 1:
The patent transforms the quality control parameter from fixed quality thresholds to variable tolerable ranges. By defining quality control as maintaining variations within acceptable bounds rather than enforcing uniform high quality, the system achieves both reliability and consistency. Products can vary in quality but remain consistent in meeting the tolerable variation criteria.
3Stability of the object's composition
If quality variation is reduced, then quality uniformity is improved, but manufacturing flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic tolerable variation ranges that can be adjusted based on product type, application, and customer requirements. This dynamic approach allows the quality control system to adapt to different manufacturing scenarios while maintaining uniformity within each specific context. The tolerable ranges are not fixed but can be modified to accommodate manufacturing variations and different product specifications.
