NFC Guide Region Display for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near field communication (NFC) techniques require machining to create convex or concave shapes for RFID reader-writers and IC tags, making them complex and difficult to implement effectively.
Innovation Solution
An information processing device with an antenna for NFC and a display unit that overlays the antenna to guide the user by displaying a smaller guide region within the reception-enabling region, ensuring proper alignment for NFC communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If convex or concave shapes are provided on the housing to maintain positional relationship, then communication reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent replaces the mechanical positioning system (convex/concave shapes on housing) with a visual guidance system (display unit showing reception-enabling region). The display unit provides real-time feedback to users about proper terminal placement, eliminating the need for complex mechanical structures while maintaining communication reliability.
Solution Approach 2:
The display unit acts as an intermediary between the antenna and the user. Instead of directly providing mechanical constraints through housing shapes, the display unit mediates by visually indicating the reception-enabling region, guiding users to place terminals correctly without requiring complex housing modifications.
2Reliability
If machining is performed on housing to create positioning shapes, then positional relationship is maintained, but ease of manufacture deteriorates
Solution Approach 1:
The patent substitutes mechanical positioning features requiring machining with an electronic display-based guidance system. The display unit shows the reception-enabling region overlaid on the housing surface, allowing users to understand proper terminal placement without any machining operations on the housing.
3Ease of operation
If display unit shows reception-enabling region, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The display unit performs multiple functions: it displays operational information, shows the reception-enabling region, and provides real-time feedback on terminal placement. By making the display unit multi-functional, the patent avoids adding separate mechanical positioning components, thereby improving ease of operation without proportionally increasing device complexity.

AI summary
A user is guided with a simple configuration so that near field communication is performed. An information processing device (1) includes an NFC antenna (520) configured to perform near field communication with an NFC terminal (100), and a display unit (53) configured to display a guide region (Ai). The guide region (Ai) serves as a guide for a communication-enabling region. The display unit (53) displays the guide region (Ai) such that the guide region (Ai) is included in the communication-enabling region (B) and the guide region (Ai) is smaller than the communication-enabling region (B).
