Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User operations for logging into applications on large-screen devices are complex, leading to poor user experience, particularly when using account and password, SMS verification code, or QR code login methods.
Innovation Solution
An application login system utilizing a first electronic device, such as a smart television, that leverages the cellular communication function of a second electronic device, like a mobile phone, to obtain login information through a one-tap operation, eliminating the need for complex character inputs or installing mobile phone applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional login methods (account and password, SMS verification code, or QR code login) are used on large-screen devices, then login security and authentication are ensured, but user operation complexity increases and user experience deteriorates
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the user and the large-screen device. The mobile terminal's short message communication function serves as the mediator to transmit login information, allowing the large-screen device to obtain authentication credentials without requiring complex user input operations. This resolves the contradiction by maintaining security through authenticated login while simplifying the user interface interaction on the large-screen device.
Solution Approach 2:
The login process is segmented into distinct functional parts: the large-screen device displays the login interface and receives the login request, while the mobile terminal handles the actual authentication communication through its short message function. This segmentation allows each device to perform its optimal function - the large-screen device provides the user interface while the mobile terminal provides the authentication mechanism, thereby simplifying operations on the large-screen device while maintaining security.
2Reliability
If account and password login is used on large-screen devices, then login security is maintained, but the number of user operations and character inputs increases
Solution Approach 1:
The system performs preliminary action by pre-configuring the mobile terminal with the user's login credentials and authentication capabilities. When login is required on the large-screen device, the authentication information is already prepared in the mobile terminal, eliminating the need for real-time character input and reducing login time while maintaining security through the pre-established authentication mechanism.
Solution Approach 2:
The mobile terminal acts as an intermediary that handles the time-consuming authentication processes off the large-screen device. By delegating the password entry and verification steps to the mobile terminal through short message communication, the large-screen device achieves fast login without compromising security, as the intermediary handles the secure credential transmission.
3Ease of operation
If QR code login is used on large-screen devices, then user operations are simplified, but additional applications need to be installed on the mobile terminal
Solution Approach 1:
The patent uses the mobile terminal's built-in short message communication function as an intermediary, which eliminates the need to install additional QR code scanning applications. The short message function is a native capability of mobile terminals, allowing the system to achieve simplified login operations while avoiding the device complexity of requiring additional application installations.
4Reliability
If SMS verification code login is used on large-screen devices, then login security is ensured, but character input operations are required
Solution Approach 1:
The mobile terminal serves as an intermediary that receives and processes the SMS verification code, then transmits it to the large-screen device through its short message communication function. This eliminates the need for users to manually input verification codes on the large-screen device, maintaining security through SMS-based authentication while removing the cumbersome character input operation from the large-screen device interface.
