Image Processing Device Hardware Key Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing devices with web-based user interfaces require additional communication with external servers to determine the validity of hardware key operations, leading to increased complexity and latency, especially when the state of the device changes dynamically.
Innovation Solution
An image processing device with a web-based user interface that includes a communication interface, a user interface display unit, a user interface input unit with hardware keys, a web-browser section to receive page data, a data analysis section to determine operation validity, and a hardware-key control section to dynamically control the validity of hardware key operations based on page data, allowing for real-time control without additional server communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional server communication is used to validate hardware key operations, then the control accuracy of hardware key validity is improved, but the device complexity and response time increase
Solution Approach 1:
The patent extracts the hardware key validity determination function from the server and relocates it to the image processing device itself. The device analyzes page data locally to determine whether hardware key operations are valid, eliminating the need for continuous server communication and reducing system complexity while maintaining control accuracy.
Solution Approach 2:
The image processing device performs self-validation of hardware key operations by analyzing page data stored in its memory. The device determines validity independently without requiring external server intervention, enabling autonomous control of hardware key functionality based on current device state.
2Reliability
If additional server communication is used to validate hardware key operations, then the control accuracy of hardware key validity is improved, but the response time increases
Solution Approach 1:
The patent implements preliminary action by pre-storing page data in the image processing device's memory before validity determination is needed. When a hardware key operation is requested, the device immediately analyzes the pre-stored page data to determine validity, eliminating the time delay associated with real-time server communication.
Solution Approach 2:
The device performs self-validation using locally stored page data, enabling instant determination of hardware key validity without waiting for server responses. This self-service approach significantly reduces response time while maintaining reliable control accuracy.
3Ease of manufacture
If web-based user interface is implemented, then the ease of updating user interface structures is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by using a web browser to render page data for controlling hardware key operations. The same web-based interface is used for both displaying information and determining operational validity, consolidating multiple functions into a single unified interface that is easy to update through server-side changes.

AI summary
An image processing device including a communication interface unit; a user interface display unit which provides information to a user; a user interface input unit having a hardware key which receives an input from the user; a web-browser section which receives page data from a web server, structures a display screen on the user interface display unit based on the page data, and displays the display screen on the user interface display unit; a data analysis section which determines whether an operation on the hardware key is to be valid or invalid based on the page data; and a hardware-key control section which controls validity/invalidity of the operation on the hardware key based on the determination made by the data analysis section.
