Auxiliary Port LED Color Coding for Data Distinction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auxiliary ports, such as USB ports, often lack clear visual indicators of their capabilities in low-light environments, making it difficult for users to distinguish between data transfer and charging ports, especially for those with vision or mobility impairments.
Innovation Solution
Incorporating light emitting diodes (LEDs) around auxiliary ports that change color in response to connection requests, with data transfer ports illuminating blue upon data connection and charge-only ports maintaining a white light, to provide visual cues for users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional markings (wattage or industry standard icons) are used to indicate port capabilities, then the solution is simple and cost-effective, but the indicators are not legible in low-light environments and are not accessible to users with vision impairments
Solution Approach 1:
The patent applies color-changing LEDs proximate to auxiliary ports to indicate different capabilities. Data transfer capable ports display a first color (e.g., blue) while charge only ports display a second color (e.g., white). This color-coding system provides clear visual distinction in low-light environments and for users with vision impairments, directly resolving the legibility issue without requiring complex additional systems.
Solution Approach 2:
The patent replaces traditional static mechanical markings (labels, icons, wattage prints) with dynamic optical indicators (LEDs). This substitution allows the indication system to be illuminated and adjusted for different lighting conditions, solving the low-light visibility problem while maintaining relative simplicity through the use of standard LED components.
2Adaptability or versatility
If all auxiliary ports are wired to provide both data and power charging capabilities, then the versatility of the ports is maximized, but it becomes difficult for users to identify which ports support data transfer without clear visual indicators
Solution Approach 1:
The patent uses color-coded LED indicators to communicate port functionality. When a data connection request is detected at a charge-only port, the proximate LED changes from a second color (white) to a first color (blue) to indicate that data transfer capability is available. This provides intuitive visual guidance to users about which ports support their intended use, directly improving ease of operation while preserving port versatility.
Solution Approach 2:
The system implements feedback by detecting data connection requests at charge-only ports and responding by changing the LED color to indicate available data transfer capability. This dynamic feedback mechanism guides users to appropriate ports based on real-time system state, making port functionality identification easier without limiting port versatility.

AI summary
The present application relates to providing auxiliary port function distinction by illuminating a first light emitting diode around a data transfer capable port wherein the first light emitting diode is illuminated in a first color, illuminating a second light emitting diode around a charge only port, receiving a first data connection request at the charge only port, illuminating the first light emitting diode a second color in response to the data connection request, receiving a second data connection request at the data transfer capable port, initiating a data connection handshake between a device connected to the data transfer capable port and a processor in response to the second data connection request, and illuminating the first light emitting diode the second color in response to the initiation of the data connection handshake.
