Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of USB-C type plugs may experience frustration due to compatibility issues between host and sink devices, leading to confusion about why certain functions, such as charging or data transfer, do not work, as they may assume the plug is defective when in fact the issue lies with device compatibility.
Innovation Solution
Incorporating a controller with LED arrays that operate according to predefined LED profiles to visually indicate the status and functionality of USB-C connections, providing clear visual feedback on operational states and error conditions through different LED colors and sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If USB-C type plugs provide multiple functional capabilities without visual indicators, then the plug can perform diverse functions (power delivery, data transfer, display), but users cannot determine which functions are active or compatible, leading to confusion and misidentification of defects
Solution Approach 1:
The patent employs LED arrays that emit different colors (e.g., green, yellow, red) to indicate various operational states and compatibility statuses of USB-C functions. Each LED color corresponds to specific functional capabilities, allowing users to visually determine which functions are active and compatible without additional displays or indicators.
2Adaptability or versatility
If USB-C type plugs operate multiple functions simultaneously, then the system provides comprehensive connectivity, but users cannot identify compatibility issues between host and sink devices
Solution Approach 1:
The patent implements a feedback mechanism where LED arrays provide real-time visual information about the operational status and compatibility of USB-C functions. The controller monitors function activation and compatibility between host and sink devices, then activates corresponding LEDs to feedback this status to users, enabling them to understand compatibility issues without technical expertise.
3Device complexity
If no visual indicators are provided for USB-C plug status, then the device design remains simple, but users assume plug defects when compatibility issues occur
Solution Approach 1:
The patent uses color-changing LED arrays to indicate different operational states and compatibility statuses. Each LED color corresponds to specific functional capabilities and compatibility conditions, allowing users to visually determine whether connection issues stem from compatibility constraints or actual plug defects, thereby maintaining user confidence without significantly increasing structural complexity.
