Image Processing Device Remote Setting via NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices require users to be physically close to designate setting options, limiting convenience and ease of use, especially when using portable terminals for bidirectional short-range wireless communication.
Innovation Solution
The system allows users to designate setting options remotely by transmitting selection information from the image processing device to the portable terminal, enabling users to select and store settings even when the terminal is out of range, using Near Field Communication (NFC) for bidirectional communication and a posture sensor to facilitate option selection through orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user designates setting options while the portable terminal is kept close to the image processing device, then the communication session can be established easily, but the user convenience and ease of operation are reduced due to the need for physical proximity
Solution Approach 1:
The image processing device transmits selection information to the portable terminal before the communication session is fully established or before the terminal moves out of range. This preliminary transmission allows the user to view and select setting options even when the terminal is kept away from the device, resolving the contradiction between ease of operation and communication reliability.
Solution Approach 2:
The selection information acts as an intermediary that carries setting option data from the image processing device to the portable terminal. This intermediary allows the user to interact with setting options remotely without requiring continuous physical proximity to the device, improving ease of operation while maintaining communication effectiveness.
2Ease of operation
If the image processing device transmits selection information during the communication session, then the user can designate setting options remotely, but the communication session must be maintained which may limit flexibility
Solution Approach 1:
The device transmits selection information at an appropriate time before the communication session ends or before the terminal moves out of range. This timing strategy allows remote setting option designation while avoiding the need to maintain complex continuous communication sessions, balancing ease of operation with session management simplicity.
3Adaptability or versatility
If the user designates setting options multiple times through different communication sessions, then comprehensive settings can be configured, but the time required for configuration increases
Solution Approach 1:
The image processing device transmits comprehensive selection information including multiple setting options in advance during the initial communication session. This preliminary transmission of complete setting information allows the user to configure all necessary settings in one session rather than requiring multiple sequential sessions, reducing configuration time while maintaining comprehensive adaptability.
