Peripheral Device Profile Management via Connection History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared peripheral devices like scanners, existing systems face challenges with user profile management, leading to cluttered operation screens and complications in switching between users, which complicates sharing and usage.
Innovation Solution
A peripheral device with a processor that stores connection history and settings information, allowing for exclusive user connections and simplified profile management by displaying only the necessary user profiles based on connection history, and switching between operation modes for different user access levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all user profiles are displayed on the operation screen for a shared peripheral device, then any user can access any profile, but the operation screen becomes cluttered and user switching becomes complicated
Solution Approach 1:
The patent extracts and displays only the necessary user profiles (currently connected user and recently connected users) from the complete set of all user profiles. This selective extraction prevents screen clutter while maintaining accessibility to relevant profiles, resolving the contradiction between profile accessibility and screen clarity.
Solution Approach 2:
The patent applies different display qualities to different user profiles based on their relevance. Currently connected user profiles are displayed with higher prominence and accessibility, while other profiles are either hidden or displayed with lower priority. This local differentiation optimizes the interface for the most common operations while maintaining system versatility.
2Adaptability or versatility
If multiple user profiles are stored and displayed simultaneously, then user switching is possible, but the device complexity increases
Solution Approach 1:
The patent performs preliminary actions by automatically managing profile selection and display based on connection history and current connection state. The system pre-determines which profiles should be displayed and in what order, eliminating the need for complex manual profile management by users and simplifying the overall system operation.
3Measurement precision
If connection history is stored for all users, then accurate profile selection is possible, but memory usage and data management complexity increase
Solution Approach 1:
The patent extracts and stores only the essential connection history information needed for profile selection (currently connected user and recently connected users) rather than maintaining complete connection records for all users. This selective data extraction maintains profile selection accuracy while minimizing data storage requirements and management complexity.

AI summary
A display control method for a peripheral device shared by a plurality of user terminals includes: storing a connection history of a user terminal for connecting the peripheral device; storing settings information specifying an operation of the peripheral device, the settings information being associated with identification information of the user terminal; selecting settings information stored in the storing settings information or identification information of a user terminal on the basis of the connection history stored in the storing a connection history; and displaying settings information or identification information selected in the selecting.
