Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for binding a mobile terminal to an imaging device require users to manually input extensive information, including URLs and device details, making the process inconvenient and insecure.
Innovation Solution
A method and system that uses a mobile terminal to scan a two-dimensional code, decode the information, and send it to a server for binding, allowing automatic app download and login, thereby simplifying the binding process and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input device information and URL to bind mobile terminal to imaging device, then binding can be completed, but user convenience deteriorates due to complicated input steps
Solution Approach 1:
A two-dimensional code is introduced as an intermediary carrier that encapsulates imaging device information. The mobile terminal scans this code to automatically obtain device details, eliminating the need for manual input of device information and URLs. The code acts as a mediator between the imaging device and the mobile terminal, enabling seamless information transfer.
Solution Approach 2:
The imaging device pre-generates a two-dimensional code containing all necessary binding information before the user arrives. This preliminary preparation of information in machine-readable form allows the mobile terminal to automatically acquire device details through scanning, eliminating the need for users to manually input information at the binding moment.
2Loss of information
If users manually enter extensive device information, then complete binding information can be obtained, but operation complexity increases
Solution Approach 1:
Multiple pieces of device information (device ID, model, IP address, port, etc.) are merged into a single two-dimensional code. This consolidation allows the mobile terminal to acquire all necessary binding information through one scanning operation, rather than requiring separate manual entry of each information element, thereby simplifying the overall process.
Solution Approach 2:
Instead of requiring users to manually recreate or input device information, the system creates a machine-readable copy (two-dimensional code) of the device information. The mobile terminal reads this copy automatically, eliminating manual transcription and reducing errors while maintaining information completeness.
3Reliability
If traditional binding methods are used, then binding can be established, but security deteriorates due to unencrypted information transmission
Solution Approach 1:
The two-dimensional code is generated with encrypted imaging device information in advance, before the binding process occurs. This preliminary encryption protects the information from being intercepted or misused during transmission. The encrypted data in the code serves as a preventive measure against security threats before they can manifest.
Solution Approach 2:
The imaging device information is transformed from plain text to encrypted format through parameter change (encryption). This transformation maintains the information's usability for binding purposes while protecting it from unauthorized access or interception during the scanning and transmission process to the server.
