Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth-based distance measurement and screen interaction are used for access control, then authentication can be performed based on proximity to the target apparatus, but the user is required to gaze and operate on the operation screen while moving toward the target apparatus
Solution Approach 1:
The system performs automatic authentication by detecting when the mobile device enters the predetermined distance range through Bluetooth measurement. The authentication process executes automatically without requiring the user to interact with the screen, allowing the device to serve itself in the authentication process.
Solution Approach 2:
The patent replaces the mechanical interaction of screen gazing and button pressing with an automatic sensor-based detection system. Bluetooth distance measurement and proximity detection automatically trigger authentication, substituting manual screen operations with automated electronic detection and recognition systems.
2Extent of automation
If automatic ranging is implemented without screen interaction, then user convenience is improved, but additional wireless communication infrastructure (UWB) is required
Solution Approach 1:
The system combines multiple wireless communication technologies (Bluetooth and UWB) into a unified authentication framework. Each technology serves multiple functions: Bluetooth provides initial device discovery and distance measurement, while UWB provides precise ranging and authentication. This multi-functional approach allows the system to achieve high automation while leveraging the strengths of different communication protocols.
Solution Approach 2:
The patent introduces an intermediary authentication server that coordinates between the mobile device and target apparatus. This server mediates the authentication process by receiving distance measurement data from both devices, verifying credentials, and authorizing access. The intermediary simplifies the overall system complexity by centralizing the authentication logic and reducing direct peer-to-peer communication requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless access control by determining user proximity to the information processing apparatus without the need for user operation on the mobile device, enhancing convenience and efficiency.
Implementation Method 1
a ranging unit configured to transmit, as an execution entity of ranging in a bidirectional ranging method of the second wireless communication, ranging request data from the information processing apparatus to a ranging target that performs the second wireless communication, and receive, at the information processing apparatus, ranging response data associated with the ranging request data from the ranging target, to thereby measure a distance between the ranging target and the information processing apparatus
Data Source
AI summary
Communication setting information for use in UWB communication is exchanged between a mobile terminal and an image forming apparatus by BLE communication. Information for identifying a ranging target is transmitted from the mobile terminal to the image forming apparatus by BLE communication or UWB communication, and the ranging target is identified by the image forming apparatus based on the received information. Ranging is started when the ranging target is identified, and the ranging request data is transmitted to the identified ranging target. The ranging is continued until a measured distance satisfies a first condition, and when the measured distance satisfies the first condition and the ranging is terminated, login authentication is performed on a user having logged in the mobile terminal, for the image forming apparatus.
