Cloud-Based COA Lookup for Mail Processing Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing address processing systems, particularly the USPS FASTforward product, face inefficiencies due to outdated technology, high license fees, and latency issues in change of address (COA) updates, making them unsuitable for low-throughput sorters and manual operations.
Innovation Solution
Implementing a two-pass system for COA processing, where a unique identifier is assigned to each mailpiece, using a potential move table on the local mail processing system and a decision results database to finalize operations, with cloud-based COA lookup and printing of updated destination information, reducing latency and operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cloud-based COA lookup is implemented, then processing efficiency is improved and timeouts are reduced, but system complexity increases
Solution Approach 1:
The patent introduces a cloud-based COA lookup server as an intermediary between the mail processing system and the COA database. This mediator handles the complexity of remote database access, authentication, and data retrieval, allowing the local mail processing system to benefit from improved efficiency without directly managing the complex infrastructure. The cloud server acts as a buffer that simplifies the interface while providing powerful backend capabilities.
2Productivity
If two-pass COA processing system is implemented, then operational costs are reduced and efficiency improved, but processing time increases
Solution Approach 1:
The patent divides COA processing into two distinct passes: a first pass that performs initial COA lookups and basic processing, and a second pass that handles remaining operations. This segmentation allows the system to distribute work more efficiently, using the cloud-based lookup server for intensive database queries in the first pass, and completing simpler operations locally in the second pass, thereby reducing overall operational costs while maintaining reasonable processing times.
Solution Approach 2:
The first pass performs preliminary COA lookups and identifies mailpieces requiring change of address updates before the second pass processes them. By performing these preliminary actions ahead of time using the efficient cloud-based lookup system, the second pass can focus on simpler, faster operations, effectively reducing the time burden of the two-pass approach.
3Loss of time
If cloud-based COA lookup is used, then latency is reduced, but reliability may be affected by network dependencies
Solution Approach 1:
The patent implements a partial local caching strategy where frequently accessed COA data is stored locally in the mail processing system. This allows the system to handle common COA lookups without network dependency, ensuring reliability for repeated queries. The cloud-based lookup is used for new or updated COA information, providing low latency when needed while maintaining system reliability through local fallback capabilities.

AI summary
Mail processing systems and methods. A method includes receiving a plurality of mailpieces in the mail processing system and associating a unique identifier with each of the plurality of mailpieces. The method includes obtaining destination address information for each of the plurality of mailpieces and comparing the destination address information with a potential move table to determine destination addresses for which there is a potential change of address. The method includes sending the destination address information to a change of address (COA) server and receiving COA results from the COA server. The method includes printing destination information on each mailpiece according to the COA results.
