Communication Device Password Recovery via Pre-Registered Email
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of home appliances, such as printers, face difficulties in changing passwords when they forget them, as these devices often lack pre-registered information for sending emails, which is necessary for password recovery processes.
Innovation Solution
A communication device with a controller that obtains email information from users, sends emails with location information, and registers new passwords after receiving registration requests, allowing password changes without inputting the original password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If email information is not pre-registered in home appliances, then device complexity is reduced, but password recovery functionality is lost
Solution Approach 1:
The system performs preliminary action by registering email information and server information in the home appliance before password loss occurs. When password recovery is needed, the pre-registered email information enables immediate password reset without requiring manual mail server configuration, thus maintaining both low device complexity and reliable password recovery functionality.
2Adaptability or versatility
If manual mail server information input is required, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service by automatically using the pre-registered mail server information to send password reset emails. The home appliance autonomously handles the email sending process without requiring users to manually configure mail server settings, thus maintaining adaptability while significantly improving ease of operation.
3Ease of operation
If password reset email is sent, then password recovery capability is improved, but loss of time occurs during email configuration
Solution Approach 1:
The system performs preliminary action by pre-registering mail server information during initial setup. This eliminates the need for time-consuming email configuration when password recovery is needed later, as the system can immediately send password reset emails using the pre-configured mail server information, thus improving password recovery capability while minimizing time loss.

AI summary
A communication device may obtain email information inputted by a user, the email information including an email address and server information for using a mail server. The communication device may send a first email by using the server information included in the email information. The communication device may register a first password and the email information in a memory in a case where a registration request is received from a terminal device which has received the first email. The communication device may send a second email by using the server information in the memory in a case where a first change instruction is obtained after the first password and the email information have been registered. The communication device may change the first password in the memory to a second password in a case where a change request is received from the terminal device.
