Wireless Tag Data Verification in Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack the capability to efficiently check the identity of sheets as they are conveyed, which is essential for ensuring accurate processing and security.
Innovation Solution
The image forming apparatus is equipped with a wireless tag communication device and a control unit that reads first data from a wireless tag on the sheet and compares it with pre-acquired second data, allowing for identity verification and subsequent image formation and data writing on the sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an image forming apparatus is equipped with wireless tag communication capability to read data from sheets, then the ability to verify sheet identity is improved, but the device complexity increases
Solution Approach 1:
The wireless tag communication device is integrated into the existing image forming apparatus, allowing it to perform both its original wireless communication function and the additional function of reading sheet data for identity verification. This multi-functionality approach improves sheet verification capability without requiring a completely separate dedicated system, thereby limiting the increase in device complexity.
2Productivity
If the apparatus reads and compares data from wireless tags on continuously conveyed sheets, then the productivity is improved through automated verification, but the measurement precision requirement increases to ensure accurate identity verification
Solution Approach 1:
The control unit compares the data read from the wireless tag on each sheet with previously acquired reference data, and based on this comparison feedback, determines whether to proceed with image formation. This feedback mechanism enables automated verification that improves productivity while maintaining measurement precision through systematic data validation.
Solution Approach 2:
Reference data is acquired and stored in advance before the actual sheet verification process. This preliminary action allows for efficient real-time comparison during sheet conveyance, improving productivity while ensuring accurate verification through pre-established reference standards.
3Productivity
If the apparatus writes data onto sheets and forms images on continuously conveyed sheets, then the productivity is improved, but the reliability of data integrity may worsen due to potential errors in continuous processing
Solution Approach 1:
The control unit performs feedback verification by reading data from the wireless tag, comparing it with reference data, and confirming data integrity before proceeding with image formation and data writing. This feedback loop ensures that even in continuous processing, each sheet is individually verified, maintaining reliability while enabling high productivity through automated batch processing.
