Mail Sorting System with Real-Time Attribute Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mail sorting systems require input mail to be presorted by weight, postage type, and customer, leading to increased processing time and reduced throughput, especially when handling multiple small batches, as each batch must be processed separately, resulting in substantial downtime and decreased efficiency.
Innovation Solution
The implementation of an upgraded software package and detection technology that allows for the processing of partially presorted or unsorted mail by detecting additional attributes such as weight, postage type, and customer information, enabling the generation of accurate reports without the need for manual presorting, using RFID technology and real-time weighing systems to optimize mail piece sorting and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mail is presorted by weight, postage type, and customer before processing, then processing accuracy and compliance with postal regulations are improved, but processing time increases and throughput decreases
Solution Approach 1:
The system performs preliminary detection of mail attributes (weight, postage type, customer information) automatically during the sorting process itself, eliminating the need for separate presorting steps. The detector reads mail piece information in real-time as mail moves through the system, and the computer system processes this data to guide sorting decisions, achieving both accuracy and high throughput.
Solution Approach 2:
The patent replaces manual presorting operations with an automated detection and control system. Optical detectors, RFID readers, and weighing sensors automatically capture mail attributes, while a computer system processes this information and controls divert mechanisms. This substitution of mechanical/manual presorting with automated sensing and control systems eliminates the trade-off between accuracy and throughput.
2Manufacturing precision
If multiple small batches of mail are processed separately with manual presorting, then sorting accuracy is maintained, but substantial downtime occurs between batches and efficiency decreases
Solution Approach 1:
The system enables continuous processing of multiple mail batches without downtime by automatically detecting batch transitions and adjusting sorting parameters in real-time. The detector continuously reads mail attributes, and the computer system dynamically updates sorting instructions based on changing batch characteristics, eliminating idle time between batches while maintaining sorting accuracy.
Solution Approach 2:
The patent implements a dynamic sorting system that adapts to changing mail batch characteristics during operation. The computer system receives continuous feedback from detectors about mail attributes and automatically adjusts divert instructions, allowing the system to handle mixed batches with varying weights, postage types, and customers without manual intervention or batch processing interruptions.
3Reliability
If manual presorting is performed for each batch, then compliance with postal authority regulations is achieved, but processing complexity and labor requirements increase
Solution Approach 1:
The system performs self-service by automatically detecting all necessary mail attributes (weight, postage type, customer information) and generating compliant sorting instructions without human intervention. The detector and computer system work together to autonomously ensure regulatory compliance by accurately categorizing mail according to postal authority requirements, eliminating the need for manual presorting while maintaining reliability.
Solution Approach 2:
The patent implements a closed-loop feedback system where detectors continuously monitor mail attributes, the computer system processes this information against regulatory requirements, and divert mechanisms are controlled based on this feedback. This automated feedback loop ensures consistent regulatory compliance while simplifying the overall system by replacing complex manual procedures with intelligent automated control.

AI summary
Disclosed is a method for processing a stream of mail pieces from different sources. The steps include detecting information corresponding to the first source from at least a first mail piece of the stream, detecting information corresponding to the second source from at least a second mail piece of the stream, counting a number of mail pieces for each of the first source and the second source, and generating a report detailing a count of mail pieces for each of the first source and the second source.
