Foldable Document Copier with Digital Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional document copiers require mechanical scanning and often scan the entire document, making them bulky and prone to errors, especially when dealing with documents of varying sizes like books, business cards, or IDs, and struggle to accurately capture text line orientation and hidden authentication marks.
Innovation Solution
A portable, adjustable, and foldable document copier system using a digital camera with a lens and light sources, equipped with sensors and a processor, that automatically detects document size and orientation, provides even illumination, and performs multi-spectral imaging to extract information efficiently, reducing mechanical parts and enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional copiers use mechanical scanning with CCD arrays to cover full document size, then copying coverage is complete, but device complexity and size increase
Solution Approach 1:
The patent replaces the mechanical scanning system (CCD arrays, fluorescent light sources, moving scanner beds) with a digital camera-based imaging system. The camera captures the entire document in a single frame or sequence of frames without mechanical movement, eliminating complex mechanical elements and synchronization requirements while maintaining full document coverage capability
Solution Approach 2:
The digital camera serves multiple functions: it acts as both the imaging device and the document scanner, replacing specialized scanning hardware. The same camera can capture various document sizes and types by adjusting field of view and imaging parameters, providing universal document copying capability without requiring different mechanical scanning systems
2Adaptability or versatility
If copiers scan the full preset maximum document size, then all document sizes are covered, but scanning time and productivity decrease
Solution Approach 1:
The system performs partial scanning by capturing only the necessary portion of the document field of view. The camera can adjust its field of view to match the actual document size, scanning only what is needed rather than the full preset maximum size, thereby improving scanning speed while maintaining adaptability to various document dimensions
Solution Approach 2:
The imaging system dynamically adjusts its field of view and imaging parameters based on the detected document size. The camera can change between wide-angle views for small documents and more focused views for larger documents, optimizing scanning speed for each document type while maintaining versatility across all sizes
3Area of stationary object
If cameras are placed close to documents to capture full view, then field of view is sufficient, but image quality and accuracy decrease
Solution Approach 1:
The patent uses a macro lens to achieve high magnification and image quality at very close distances to the document. The macro optical system allows the camera to be positioned extremely close to capture the entire document field of view while maintaining sufficient image resolution and accuracy for text line orientation detection and authentication mark verification, effectively adding an optical dimension solution to the proximity problem
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables rapid, accurate, and error-reduced data extraction from various document types, including those with hidden authentication marks, by using digital imaging and OCR, and can transfer data directly to a computer, improving document copying quality and reliability.
Implementation Method 1
a digital camera equipped with a lens and at least one light source
Implementation Method 2
the light source is equipped with light diffuser to provide even illumination of the document
Implementation Method 3
Acquiring data may be initiated by the user or may be initiated automatically when the system senses that a new document was placed
Implementation Method 4
Third, OCR recognizes symbols and characters
