Production Code Reconstruction via Cycle Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling and regulating production processes in printed product manufacturing are limited by the small amount of information and control commands that can be stored in print marks, leading to errors and waste when codes become illegible, especially in variable production processes.
Innovation Solution
The method involves printing codes, such as data matrix or QR codes, on printing material to store and record production information, with the use of clock and cycle information to reconstruct and verify data when codes are illegible, ensuring stable production with reduced errors and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If codes are printed on substrate to store production information, then the amount of information that can be stored and retrieved is increased, but the system becomes vulnerable to errors when codes become illegible
Solution Approach 1:
The patent applies preliminary action by pre-defining the temporal structure and cycle information of the production process before actual production occurs. The control system is pre-programmed with expected cycle times, sequence patterns, and process parameters. This allows the system to predict what data should be present in codes at any given moment, enabling reliable reconstruction even when individual codes become illegible during production.
2Reliability
If redundant data storage is implemented in codes, then error resistance is improved, but the complexity of code structure and analysis increases
Solution Approach 1:
The patent applies segmentation by dividing production information into multiple temporal segments distributed across different codes printed on successive substrates. Instead of storing all information in a single complex code, the system splits data across multiple simpler codes that can be individually read and reconstructed. Each code contains a portion of the production information tied to specific temporal cycle data, reducing the complexity burden on any single code while maintaining overall system reliability.
3Stability of the object's composition
If clock and cycle information are used to reconstruct codes, then production stability is improved, but the requirement for precise timing and synchronization increases system complexity
Solution Approach 1:
The patent applies feedback by continuously monitoring actual production timing and cycle completion, then using this real-time feedback to verify and adjust code reconstruction. The control system compares expected cycle times against actual measured times, and uses this feedback loop to maintain synchronization between the physical production process and the digital code representation. This feedback mechanism ensures stable reconstruction without requiring overly complex predetermined timing arrangements.
