Operation Panel NFC and USB Port Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of both a mobile terminal using NFC and a device using a USB port on the same operation panel unit for an image forming apparatus can lead to mutual interference due to their overlapping positions.
Innovation Solution
The operation panel unit is designed with the NFC reading portion and USB port positioned on different surfaces of the display portion, such as on opposite side surfaces or edge portions, to prevent interference, with optional inclination of the NFC reading surface to facilitate use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the NFC reading portion and USB port are disposed on the same surface of the display portion, then the operation panel unit can provide multiple input methods (NFC and USB) for device connection, but mutual interference occurs between the NFC and USB functions when both are present at the same time
Solution Approach 1:
The operation panel unit is segmented into different surfaces for different input methods. The NFC reading portion is disposed on a first surface of the display portion, while the USB port is disposed on a second surface of the display portion. This spatial segmentation prevents mutual interference between NFC and USB functions while maintaining both input methods.
2Reliability
If the NFC reading portion and USB port are disposed on different surfaces of the display portion, then mutual interference between NFC and USB functions is avoided, but the device complexity increases due to spatial arrangement constraints
Solution Approach 1:
The patent transitions from two-dimensional arrangement (both ports on the same surface) to three-dimensional arrangement (ports on different surfaces of the display portion). This dimensional change allows NFC and USB functions to coexist without interference while maintaining a compact overall structure.
