Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices for user authentication in image forming devices do not effectively utilize direction detection functions of wireless communication to ensure secure and timely image formation based on user proximity, often requiring additional authentication methods like ID cards, which can be inconvenient and prone to timing mismatches.
Innovation Solution
An electronic device equipped with a wireless communication unit that acquires direction information from a terminal device using beacon signals, allowing image formation only when the terminal is within a predetermined angle range, thereby eliminating the need for additional authentication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is performed using ID card reading, then security is improved, but operation convenience deteriorates and additional authentication devices are required
Solution Approach 1:
The patent replaces the mechanical card reading authentication system with a wireless direction-based authentication system. The electronic device uses wireless communication to detect the direction and position of the terminal device, substituting physical card insertion with wireless spatial detection. This eliminates the need for card readers while maintaining security through directional verification.
Solution Approach 2:
The wireless communication unit serves multiple functions: it detects direction information for authentication, determines terminal position relative to the electronic device, and enables image formation control. This multi-functional approach eliminates the need for separate card reading devices while maintaining authentication security.
2Reliability
If additional authentication methods like ID cards are used, then security is improved, but device complexity increases
Solution Approach 1:
The wireless communication unit is designed to perform multiple functions including direction detection, position determination, and authentication verification. By making this single component multi-functional, the patent avoids adding separate card readers or authentication devices, thereby maintaining security while reducing overall device complexity.
3Productivity
If image formation is performed without direction verification, then productivity is improved, but security deteriorates
Solution Approach 1:
The patent performs direction verification and terminal position determination as preliminary actions before initiating image formation. The wireless communication unit detects the direction of the terminal device in advance, and only when the terminal is confirmed to be in the correct directional range does the system proceed with image formation. This preliminary verification maintains security while enabling quick subsequent execution.
4Reliability
If direction detection is implemented, then authentication security is improved, but measurement precision requirements increase
Solution Approach 1:
The patent defines a directional range (first range) as a predetermined angle range from a reference position, transforming the precision requirement from detecting exact direction to verifying whether the terminal falls within an acceptable angular range. This parameter transformation maintains security by ensuring the terminal is in the correct general direction while reducing the burden of extreme precision.

AI summary
An electronic device for wirelessly communicating with a terminal device by a wireless communicator includes a direction information acquisition unit and a processor. The direction information acquisition unit acquires, based on a beacon signal received by the wireless communicator from the terminal device, direction information related to a direction of the terminal device with respect to a reference position of the electronic device. The processor performs image formation based on an image forming job corresponding to terminal identification information in the beacon signal when the processor determines that, based on the direction information, the terminal device is positioned in a first range which is a direction range of a predetermined angle.
