Operation Panel NFC Communication Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with operation panels that use near field communication for wireless operation with mobile terminals, there is a risk of erroneous operation of keys due to the mobile terminal or its accessories touching the operation keys, leading to unintended key presses.
Innovation Solution
The electronic device incorporates a processing unit that determines the validity of the operation result of a second operation key based on the operations of a first operation key and the second key, invalidating the result if the first key is operated, thereby reducing the likelihood of erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication unit is arranged within the specific region of the operation panel for wireless communication with mobile terminal, then the ease of operation is improved, but the reliability deteriorates due to risk of erroneous key operations
Solution Approach 1:
The system performs preliminary detection of mobile terminal proximity via NFC before enabling wireless operation mode. This preliminary action allows the system to prepare for the wireless operation scenario and activate the validation mechanism that compares first key operations with second key operations, thereby preventing erroneous operations while maintaining ease of use
2Ease of operation
If the mobile terminal is held over the communication unit for wireless communication, then the ease of operation is improved, but the object-affected harmful factors increase due to accidental key presses
Solution Approach 1:
The system implements feedback by continuously monitoring the relationship between first key operations (performed before wireless mode) and second key operations (performed during wireless mode). When a second key operation is detected, the system checks whether a corresponding first key operation occurred, and provides feedback by invalidating the second operation if no match is found, thereby eliminating erroneous operations caused by accidental key presses
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
This configuration effectively minimizes the occurrence of erroneous key operations when the mobile terminal is held over the communication unit, ensuring accurate user input and reducing malfunctions.
Implementation Method 1
The communication unit uses near field communication (NFC) or the like to communicate with the mobile terminal

AI summary
An electronic device is provided with an operation panel, a communication unit, and a processing unit. The operation panel has a first operation key and a second operation key within a specific region. The communication unit is arranged within the specific region of the operation panel, and is a location for communicating wirelessly with a mobile terminal that is in a state opposing the specific region. The processing unit determines whether an operation result of the second operation key is valid or invalid on the basis of operations of the first operation key and the second operation key in such a way that the operation result of the second operation key is invalidated in a case where the first operation key has been operated.
