Non-contact Payment Device Angled Placement Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact communication devices struggle to accommodate various-sized articles with non-contact communication functions, such as smart phones and tablet terminals, without increasing the device's width, which is a challenge in cashless payment systems.
Innovation Solution
A non-contact communication device with a placement portion featuring a first placement surface forming a smaller angle and a second placement surface forming a larger angle, both allowing articles to be inserted in a depth direction, with the second surface having a wider width, enabling compatibility with different article sizes without expanding the device's width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device width is increased to accommodate larger articles like tablet terminals, then compatibility with various-sized articles is improved, but the device size becomes larger
Solution Approach 1:
The patent introduces a multi-level placement structure with first and second placement surfaces positioned at different heights and angles. This vertical dimensionality allows the device to accommodate articles of various widths without increasing the horizontal device footprint, resolving the contradiction between adaptability and device size.
Solution Approach 2:
The placement portion is segmented into multiple independent placement surfaces (first placement surface and second placement surface), each capable of accommodating different article sizes. This segmentation allows flexible adaptation to various article dimensions while maintaining a compact overall device structure.
2Adaptability or versatility
If a single placement surface is used, then the device structure is simpler, but compatibility with various article sizes is reduced
Solution Approach 1:
The placement portion is divided into multiple independent placement surfaces with different orientations and positions. Each surface can be optimized for specific article types, providing enhanced adaptability while maintaining modular simplicity in the overall structure.
Solution Approach 2:
Different placement surfaces are designed with different local characteristics (angles, positions, orientations) to match specific article types. The first placement surface accommodates one type of article while the second surface accommodates another, providing localized optimization without requiring complete structural redesign.

AI summary
A non-contact communication device includes a placement portion (30) and a non-contact communication unit (20) configured to perform non-contact communication to/from an article. The non-contact communication unit (20) includes a first antenna (23A) and a second antenna (23B). The placement portion (30) includes a first placement surface portion (32A) forming a first angle with respect to a device width direction (Hr), and a second placement surface portion (32B) forming a second angle larger than the first angle with respect to the device width direction (Hr). The first antenna (23A) is built into the first placement surface portion (32A), while the second antenna (23B) is built into the second placement surface portion (32B). The second placement surface portion (32B) is positioned above the first placement surface portion (32A), and has a width that is larger than a width of the first placement surface portion (32A).
