Problem
Physical document files are difficult to access, organize, and process due to their disorganized and non-uniform nature, leading to costly and time-consuming manual handling, which can result in errors, damage, and security risks.
Innovation Solution
Systems and methods for identifying, isolating, and aligning individual sheets from a stack of physical documents using sensors, air flow, and machine learning to facilitate automated processing, such as scanning, by determining characteristics like shape, size, orientation, and position, and correcting for systematic errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If physical documents are stored in archives and warehouses, then information storage capacity is improved, but access time and cost increase
Solution Approach 1:
The patent creates digital copies of physical documents through automated scanning and image capture. The detection unit captures images of document pages, and the controller processes these images to create digital representations that can be stored and accessed electronically, eliminating the need to physically retrieve documents from archives.
Solution Approach 2:
The patent replaces manual document handling with an automated system comprising detection units, controllers, and manipulation tools. The system automatically detects document characteristics, manipulates documents for optimal positioning, and captures images without human intervention, substituting mechanical manual operations with automated electronic control.
2Volume of stationary object
If physical documents are stored as disorganized stacks, then storage space utilization is improved, but document location and identification difficulty increases
Solution Approach 1:
The detection unit provides feedback about document characteristics (position, orientation, shape) to the controller, which then adjusts manipulation tool positions accordingly. This closed-loop feedback system enables the automated identification and positioning of documents even in disorganized stacks, resolving the contradiction between compact storage and easy identification.
3Ease of operation
If manual handling of physical documents is used, then flexibility in processing is improved, but error rate and document damage increase
Solution Approach 1:
The system performs self-positioning and self-alignment of documents through automated detection and manipulation. The detection unit identifies document characteristics, and the controller automatically adjusts manipulation tool positions to optimize document placement for scanning, eliminating the need for manual intervention while maintaining processing flexibility and reducing damage risk.
4Productivity
If automated detection and manipulation tools are present in the zone of detection, then document processing efficiency is improved, but detection accuracy decreases
Solution Approach 1:
The system dynamically positions manipulation tools based on real-time detection feedback. The controller continuously monitors document characteristics and adjusts tool positions accordingly, allowing tools to be present in the detection zone without compromising accuracy, as their positions are actively optimized based on detected document states.

AI summary
Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.
