Solution Overview
Problem
Conventional sheet counting devices lack flexibility and reliability in processing stacked sheets, particularly in detecting additional information such as coding or markings, which limits their functionality and accuracy in counting and identification processes.
Innovation Solution
A device with a linear illumination section and imaging path is designed to improve the processing of stacked sheets by generating a linear illumination section on the sheets and imaging it in a detection plane, allowing for flexible operation, enhanced error resistance, and the detection of one-dimensional or multidimensional coding for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional counting devices only determine distance from sheet edge to printed image, then the device structure remains simple, but the functionality is limited and cannot detect additional information such as coding or markings
Solution Approach 1:
The optical detection system is designed to perform multiple functions: it can detect the distance from sheet edge to printed image for counting, and simultaneously detect one-dimensional or multidimensional codes and markings on the sheets. This multi-functional capability resolves the contradiction by enabling the device to handle various sheet types and detection requirements without requiring separate specialized devices.
Solution Approach 2:
The patent transitions from simple linear distance measurement to two-dimensional or multi-dimensional code detection by implementing an imaging path that captures spatial information across the sheet surface. This dimensional expansion allows the system to recognize patterns, codes, and markings while maintaining the original counting function, thereby increasing versatility without proportionally increasing complexity.
2Reliability
If conventional devices only perform basic counting, then the device complexity is low, but the error resistance and reliability of the counting process is reduced
Solution Approach 1:
The system incorporates feedback mechanisms where detected codes and markings are processed by control devices to verify sheet identification and counting accuracy. This feedback loop enables error detection and correction, improving reliability by allowing the system to validate results and identify anomalies in the counting process.
Solution Approach 2:
The device performs preliminary detection of codes and markings before final counting confirmation. By pre-identifying sheet characteristics and codes, the system can prepare verification data in advance, ensuring more reliable counting results and reducing errors in the overall processing workflow.
3Loss of information
If the device processes only basic sheet counting, then the processing speed is maintained, but additional information such as coding cannot be recorded and made available for further processing
Solution Approach 1:
The imaging path creates optical copies or images of the sheet surface, codes, and markings, which are then captured and processed digitally. This copying mechanism preserves all visual information from the sheets without requiring physical handling or contact, enabling complete information capture while maintaining processing efficiency through non-contact optical methods.
