Innovation Solution
A digital process controller that receives and validates a process recipe comprising multiple steps, displays validation results, and executes the recipe step-by-step, using a user interface to preview outcomes and indicate errors, ensuring all stakeholders' needs are met through internal and external validation processes, and tracks the status and progress of each step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple process steps are executed across different printing and finishing devices to produce complex composed end products, then the production capability and versatility are improved, but the error rate and production reliability deteriorate
Solution Approach 1:
The patent segments the complex production process into individual process steps, each with specific validation rules. The process recipe is divided into discrete steps that can be independently validated, allowing the system to maintain high versatility while ensuring reliability through step-by-step verification of each process segment.
Solution Approach 2:
The patent implements preliminary validation of process recipes before actual production execution. By validating process steps in advance and checking prerequisites before each step, the system prevents errors from occurring during production, thereby maintaining reliability while supporting complex multi-step processes.
2Reliability
If process validation and error checking are performed for each process step, then the production reliability is improved, but the production time and complexity increase
Solution Approach 1:
The patent performs validation of process recipes and checking of prerequisites before production execution. By conducting these checks in advance, the system prevents errors that would require time-consuming corrections during production, ultimately reducing total production time while maintaining high reliability.
Solution Approach 2:
The patent implements feedback mechanisms that provide information about validation results and error states. This allows operators to quickly understand and correct issues without time-consuming trial-and-error approaches, improving reliability while minimizing time loss through informed decision-making.
3Reliability
If trial-and-error runs are conducted to validate production processes, then the process reliability is improved, but the production cost and time loss increase
Solution Approach 1:
The patent validates process recipes and checks prerequisites before actual production runs. This preliminary validation replaces costly trial-and-error production runs with efficient pre-execution checking, maintaining process reliability while dramatically improving production efficiency by avoiding wasted material and time.
4Manufacturing precision
If comprehensive validation of process recipes is performed, then the manufacturing precision is improved, but the device complexity and operational complexity increase
Solution Approach 1:
The patent divides comprehensive validation into segmented, manageable components including process recipe validation, prerequisite checking, and step-by-step verification. This segmentation maintains manufacturing precision while reducing operational complexity by breaking down complex validation tasks into discrete, understandable steps.
Solution Approach 2:
The patent implements automated validation systems that perform checking and verification autonomously. The system self-validates process recipes and checks prerequisites without requiring manual intervention, thereby achieving high manufacturing precision while minimizing the operational complexity burden on users.

AI summary
Digital process controller and a method for controlling a production process of a complex composed end product by process jobs. Each process job is a pre-print job, a print job or a finishing job. The digital process controller is connected to a digital network, provided with a user interface and configured to receive print content and print and finishing specifications of the complex composed end product via the digital network, to receive a selection of a process recipe for the complex composed end product, the process recipe comprising a plurality of process steps and the relationships between the process steps, to decompose the production of the complex composed end product into the plurality of process steps in the process recipe, to execute the process recipe process step by process step, to validate each process step individually, and to display the validation result of each process step at the user interface.
