Document Scanner Cover NFC Placement to Prevent Device Falls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face issues with external devices, such as IC cards and smartphones, falling off the NFC communication area on the document cover when the cover is opened, leading to potential damage or loss.
Innovation Solution
A document scanner with a document cover that pivots to cover or uncover the document glass, featuring an indication on its end surface for proximity-based wireless communication, ensuring the device remains secure during cover movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the NFC communication area is provided on the upper surface of the document cover, then short-range wireless communication can be established, but external devices may fall off when the cover is opened
Solution Approach 1:
The NFC communication area is relocated from the upper surface to the end surface of the document cover, changing the spatial dimension of the communication interface. This dimensional shift allows the communication area to be positioned at a location that does not interfere with the cover's opening motion, thereby preventing external devices from falling off while maintaining wireless communication functionality.
2Area of stationary object
If the document cover is made large enough to provide a sufficient NFC communication area, then wireless communication is enabled, but the cover becomes harder to open and close
Solution Approach 1:
Instead of expanding the NFC communication area on the upper surface which would increase cover size and reduce operability, the communication area is repositioned to the end surface of the cover. This dimensional relocation maintains adequate communication area size while preserving the cover's ease of operation.
3Adaptability or versatility
If the NFC communication area is on the upper surface, then wireless communication is established, but the external device may be damaged or lost when falling to the floor
Solution Approach 1:
The NFC communication area is relocated from the upper surface to the end surface of the document cover. This positional change ensures that when the cover is opened, external devices remain secured on the cover rather than falling to the floor, thereby eliminating the damage risk while preserving wireless communication functionality.

AI summary
A document scanner includes a casing and a document cover disposed above the casing. The casing includes a document glass and houses an image scanner. The document cover has one end portion and the other end portion opposite to the first end portion in a first direction and is configured to pivotally move about the one end portion between a closed position in which the other end portion covers the document glass and an open position in which the other end portion uncovers the document glass. The other end portion has an end surface that intersects, when the document cover is at the closed position, with an upper surface of the document glass. The end surface has an indication indicating a location to which an external device is to be brought into proximity to establish short-range wireless communication between the document scanner and the external device.
