Mail Routing via Image Recognition and Vector Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large organizations face challenges in efficiently routing mail items with insufficient, incorrect, or erroneous addresses, and in managing communications across a smaller number of hubs or a single hub, especially when entity locations, functions, or operations change.
Innovation Solution
The development of apparatus and methods that include computer-readable code and media for processing mail items, which utilize image recognition and library vectors to decompose mail item parts into string vectors, quantify closeness to potential destinations, and route items based on probabilistic predictions, ensuring accurate delivery even when addresses are incomplete or incorrect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mail items are routed using traditional address-matching methods, then routing simplicity is maintained, but routing accuracy deteriorates when addresses are insufficient, incorrect, or erroneous
Solution Approach 1:
The patent replaces traditional mechanical address-matching methods with an image recognition system that captures mail item images, extracts visual features, and compares them against a library of known destination images using pattern recognition algorithms. This substitution enables accurate routing of misaddressed mail by recognizing destinations through visual patterns rather than relying solely on text-based address matching.
Solution Approach 2:
The patent introduces an image library as an intermediary between the mail item and the routing decision. The library stores pre-captured images of mail items destined for various locations, serving as a reference medium that enables comparison and pattern matching. This intermediary allows the system to resolve routing decisions even when address information is insufficient or incorrect, by matching visual patterns against the library.
2Productivity
If the organization uses a smaller number of hubs to service entities, then operational efficiency is improved, but adaptability to changes in entity locations and functions deteriorates
Solution Approach 1:
The patent implements a dynamic routing system where the image library is continuously updated with new mail item images and destinations. The system adapts to changes in entity locations and functions by learning from incoming mail patterns and automatically adjusting routing decisions. This dynamic capability allows a reduced number of hubs to effectively service changing organizational structures without sacrificing adaptability.
Solution Approach 2:
The system incorporates feedback mechanisms where routing outcomes are monitored and used to refine the image library and pattern recognition algorithms. When mail items are successfully routed or when routing errors occur, this information feeds back into the system to improve future routing decisions. This feedback loop enables the hub structure to adapt to organizational changes while maintaining high operational efficiency.
3Loss of information
If current hub address information is provided to the public, then information currency is maintained, but the complexity of keeping information updated increases
Solution Approach 1:
The patent implements a self-updating system where the image library automatically learns and updates destination information from incoming mail items. The system captures images of successfully delivered mail, extracts destination information, and adds these to the library without manual intervention. This self-service mechanism maintains information currency while eliminating the complexity of manual information updates and distribution.

AI summary
Apparatus, methods, media and code for routing mail items to different destinations. A driven mail conveyor may receive: a first mail item that includes a paper envelope displaying in an addressee segment an institution name and institution address information, the first mail item including a first part; and a second mail item that includes a paper envelope displaying in the addressee segment the institution name and the institution address information and no other institution address information, the second mail item including a second part. A processor may electronically route, based on a first text string vector of the first part, the first mail item to a first mail item destination in the institution; and, based on a second text string vector of the second part, the second mail item to a second mail item destination in the institution.
