Mail Distributing Apparatus Prioritizing Valid Addresses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mail distributing systems face inefficiencies due to the presence of invalid mailing addresses, leading to prolonged wait times for transmitting mails to valid addresses and congestion caused by high volumes of fail messages.
Innovation Solution
A mail distributing apparatus that records successful transmission times for each address, prioritizes transmission to addresses that have successfully received mails within a predetermined period, adjusts transmission periods based on fail rates and reply times, and dynamically changes the mail transmitting schedule to prevent congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If mails are transmitted to all addresses in the list in advance, then the transmission process is simple and systematic, but the average wait time for completing transmission to valid addresses increases due to inclusion of invalid addresses
Solution Approach 1:
The system performs preliminary actions by recording transmission status and dates for each address in advance, and pre-calculating which addresses are likely to be valid based on previous successful transmissions within a predetermined period. This allows the system to prioritize transmission to addresses with higher success probability, thereby reducing the average wait time for completing transmission to valid addresses.
Solution Approach 2:
The system changes the transmission parameter by dynamically adjusting the transmission order based on recorded data. Instead of transmitting to addresses in a fixed list order, the system reorders transmission priorities based on parameters such as previous successful transmission dates and periods, thereby optimizing the average wait time for valid address transmission completion.
2Productivity
If mails are transmitted to addresses with higher likelihood of validity first, then the average wait time for completing transmission is shortened, but the transmission control complexity increases
Solution Approach 1:
The system implements self-service by automatically recording transmission status, calculating validity periods, and determining transmission priorities without requiring external intervention. The mail distributing apparatus itself performs the complex tasks of data recording, analysis, and decision-making, thereby improving transmission efficiency while managing complexity internally rather than externally.
Solution Approach 2:
The system uses feedback mechanisms by continuously recording transmission results and using this information to adjust future transmission priorities. The recorded data on successful transmissions and invalid addresses provides feedback that enables the system to refine its address selection algorithm, thereby improving productivity while the complexity is managed through automated feedback loops rather than manual control.
3Speed
If transmission period is reduced to transmit more mails, then the overall transmission speed increases, but congestion occurs due to large number of fail messages returned
Solution Approach 1:
The system performs preliminary filtering by identifying and prioritizing addresses with higher validity probability before transmission. By pre-recording successful transmission dates and calculating validity periods, the system prepares a prioritized transmission list that reduces the expected number of fail messages, thereby enabling faster transmission speeds without proportionally increasing congestion from failed transmissions.
Solution Approach 2:
The system changes transmission parameters by dynamically adjusting the transmission period based on the prioritized address list. Instead of using a fixed transmission period, the system modifies transmission timing and batch sizes according to the predicted fail rate of each address group, thereby optimizing transmission speed while preventing congestion from excessive fail messages.

AI summary
There is provided a mail distributing apparatus, a program and a mail transmitting method capable of shortening an average wait time for completing transmission of mails. The mail distributing apparatus has a transmission recording section for recording the date and time when a mail has been successfully transmitted last per mailing address, an address selecting section for selecting the addresses to which the mails have been successfully transmitted last on the date and time within a predetermined period by making reference to the transmission recording section when it is commanded to distribute mails to a plurality of addresses and a transmitting section for transmitting the mails to the addresses selected by the address selecting section at first and then transmitting the mails to the other addresses.
