Visual Indicator for Portable Device Data Transfer Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in distinguishing between older and newer USB connectors due to physical similarity, which can lead to underutilization of higher data transfer capabilities as older connectors may not support enhanced data communication rates.
Innovation Solution
A portable device with a visual indicator, such as an LED, that adjusts its behavior based on the operating mode or data transfer capacity of the host interface, allowing users to recognize when data transfer is limited to a lower rate than the device's maximum capability by using different colors or pulsing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If backward compatibility is implemented to extend usefulness of older devices, then connectivity and device compatibility are improved, but users cannot distinguish between legacy connectors and newer connectors with enhanced data communication rates
Solution Approach 1:
The patent applies color changes to the visual indicator (LED) to communicate different operational states. Specifically, the LED displays different colors or blinking patterns to indicate whether the device is connected via a legacy connector (lower data rate) or a newer connector (higher data rate), enabling users to visually distinguish between connector types without physical differences
Solution Approach 2:
The patent introduces a visual indicator (LED) as an intermediary element between the connector interface and the user. This intermediary provides visual feedback about the connector type and data transfer rate, resolving the information asymmetry between the physical connector appearance and its actual capabilities
2Device complexity
If physical similarity between older and newer connectors is maintained for simplicity, then manufacturing and design are simplified, but users experience difficulty in distinguishing between different data transfer capacities
Solution Approach 1:
The visual indicator serves as an intermediary that bridges the gap between the simplified physical connector design and the need for user identification. The LED provides visual information about data transfer capabilities without requiring physical differentiation of the connectors themselves
Solution Approach 2:
The patent replaces potential mechanical or physical differentiation of connectors (such as different shapes, sizes, or keying mechanisms) with an optical signaling system. This substitution maintains connector simplicity while providing clear identification through visual feedback
