Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low-light environments, it is difficult to systematically and accurately connect plug-in devices to mobile wireless communications devices due to inadequate illumination of plug-in device ports, and there is a need for a method to distinguish between compatible and incompatible devices during the connection process.
Innovation Solution
A near-field communication (NFC) system that includes a mobile device with a plug-in device port, a light source, an optical sensor, and a controller, which illuminates the port based on NFC communications and ambient light levels, and displays indicators for the location and compatibility of the plug-in device, using NFC sensors to facilitate controlled and systematic plugging in.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If no illumination is provided for plug-in device ports, then the device structure remains simple and energy consumption is low, but in low-light environments the user cannot systematically and accurately connect plug-in devices
Solution Approach 1:
The system performs preliminary NFC communication to identify the plug-in device and determine the appropriate port before illumination is activated. This ensures illumination is provided only when needed and at the correct location, avoiding unnecessary complexity while solving the low-light connection problem
Solution Approach 2:
The patent introduces an intermediary illumination system that is activated based on NFC detection. This intermediary component bridges the gap between simple device structure and the need for guided connection in low-light environments, providing illumination only when and where required
2Measurement precision
If illumination is provided for all plug-in device ports, then connection accuracy is improved, but it becomes difficult to distinguish between compatible and incompatible devices
Solution Approach 1:
The illumination system provides different illumination characteristics (such as color or intensity) for different ports based on NFC-detected compatibility information. Compatible ports receive one type of illumination while incompatible ports receive another, allowing users to distinguish compatibility while maintaining connection accuracy
Solution Approach 2:
The system uses NFC communication to obtain feedback about device compatibility and uses this information to control the illumination pattern. This feedback loop ensures that illumination provides useful compatibility information rather than just generic visibility, solving both connection accuracy and compatibility distinction
3Adaptability or versatility
If NFC communication is used to establish Bluetooth connection, then wireless connectivity is improved, but the connection process may fail without visual guidance on where to plug in the device
Solution Approach 1:
The illumination system acts as an intermediary between NFC wireless communication and physical plug-in connection. It translates the abstract NFC pairing process into concrete visual guidance showing users exactly where to plug in the device, making the overall connection process easier while maintaining wireless versatility
Solution Approach 2:
The system performs preliminary NFC communication to establish wireless connectivity and identify the correct physical port before providing illumination guidance. This preliminary action ensures that the illumination guidance is relevant and accurate, making the subsequent physical connection straightforward
