Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional short-run printing methods are used, then setup time is reduced for small volumes, but printing cost per MSI becomes very high
Solution Approach 1:
The patent combines multiple discrete short-run print jobs into a single consolidated print job that can be processed on high-volume offset presses. By merging jobs with similar characteristics (paper type, size, color requirements) into aggregate print runs, the system achieves economies of scale while still serving individual customer needs, thereby reducing the effective setup cost per job.
Solution Approach 2:
The system performs preliminary aggregation and consolidation of print jobs before they reach the printing stage. By pre-grouping compatible jobs and preparing consolidated print files in advance, the system eliminates the need for frequent press setups and changes, allowing high-volume presses to operate continuously at optimal efficiency.
2Quantity of substance
If high-volume offset printing presses are used for short-run jobs, then printing cost per MSI decreases, but setup time and complexity increase
Solution Approach 1:
The patent applies different processing approaches to different segments of print jobs based on their specific characteristics. Jobs are analyzed and grouped by paper type, size, color requirements, and quantity, then assigned to appropriate press configurations. This localized optimization allows high-volume presses to handle suitable jobs efficiently while minimizing setup requirements.
Solution Approach 2:
The system dynamically adjusts printing parameters such as press speed, ink density, and paper feed rates based on the specific characteristics of each aggregated job batch. By optimizing these parameters for consolidated runs rather than individual jobs, the system achieves cost efficiencies comparable to high-volume printing without requiring the same level of setup complexity.
3Adaptability or versatility
If discrete print jobs are processed individually, then customization is maintained, but capacity utilization of printing equipment decreases
Solution Approach 1:
The patent segments the print production process into distinct phases: job aggregation, consolidation planning, consolidated printing, and post-print distribution. This segmentation allows individual customer customizations to be preserved in the digital domain while the physical printing phase operates on consolidated batches, thereby maximizing equipment utilization without sacrificing job-specific requirements.
Solution Approach 2:
The system introduces a digital intermediary layer (computer-generated aggregate print files) between the customer's customized job requirements and the physical printing process. This intermediary allows high-volume presses to print consolidated batches while maintaining the ability to deliver customized final products, thus bridging the gap between customization needs and equipment efficiency.
4Quantity of substance
If rapid changeover production machinery is used, then setup costs are reduced, but print quality and speed decrease
Solution Approach 1:
The patent employs dynamic job aggregation strategies that adapt to the capabilities and availability of different printing resources. High-volume offset presses are assigned to job batches where their speed and quality advantages can be fully utilized, while rapid changeover machinery is reserved for jobs requiring frequent customization. This dynamic allocation optimizes both quality and cost across the entire production system.
