Facsimile Apparatus Re-entry Mechanism for Transmission Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional facsimile transmission systems, especially IP fax, fail to prevent mistaken transmissions due to user errors in inputting destination numbers and communication network selections, leading to information leakage when incorrect networks are chosen, even if the fax number is correct.
Innovation Solution
A facsimile apparatus with a mechanism that requires re-entry of both the destination number and communication network after initial input, comparing these entries to ensure matching before proceeding with transmission, thereby preventing unintended transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user inputs the fax number twice for confirmation, then the mistaken transmission due to typing error is prevented, but the transmission cannot be prevented when the wrong communication network is selected
Solution Approach 1:
The patent segments the transmission parameters into two distinct parts: destination fax number and communication network. Each segment is independently confirmed by requiring the user to re-enter both parameters separately, ensuring that errors in either segment are detected without conflating the two confirmation processes.
Solution Approach 2:
The patent performs preliminary confirmation of both the destination fax number and communication network before actual transmission occurs. By requiring re-entry of both parameters and comparing them against the original inputs, the system prevents mistaken transmissions before they happen, rather than attempting to correct errors after transmission begins.
2Adaptability or versatility
If the system allows selection of multiple communication networks, then the system can connect to different networks (Intranet, NGN, VoIP GW), but the risk of transmitting to wrong destination increases when network selection is involved
Solution Approach 1:
The patent implements a feedback mechanism where the system compares the re-entered communication network parameter against the originally selected network. This feedback loop provides immediate verification that the user intends to use the correct network, preventing information leakage caused by accidental selection of wrong networks while maintaining support for multiple network types.
3Ease of operation
If the user directly inputs destination without registration, then flexibility in transmitting to any number is achieved, but the probability of inputting wrong number increases
Solution Approach 1:
The patent applies preliminary confirmation by requiring the user to re-enter both the destination fax number and communication network parameters before transmission. This preliminary action catches potential input errors while preserving the flexibility of direct input, as users can still input any number directly but must then confirm it through re-entry.

AI summary
The present facsimile apparatus accepts inputs of a destination of facsimile transmission and a communication network to be used for the facsimile transmission, and further accepts re-entry of the destination and the communication network. The facsimile apparatus is controlled so as to execute the facsimile transmission if both the first input destination and communication network match the re-entered destination and communication network, and so as not to execute the facsimile transmission if at least one of the first input and accepted destination and communication network does not match the re-entered and accepted destination and communication network.
