Universal USB Substrate for Multi-Standard Connector Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with USB connectors face challenges in efficiently supporting multiple USB standards and plug types, leading to design complexities and increased manufacturing costs due to the need for separate components and testing for different USB types.
Innovation Solution
The electronic device incorporates a substrate with both first and second USB standard conductors, allowing for the selective mounting of either a USB3.1 Type-A or USB2.0 Type-A plug, or a USB Type-C plug, using a common wiring pattern that connects pads on the substrate to external terminals, enabling flexible manufacturing and reduced testing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate components and testing are used for different USB types, then each USB standard can be properly supported, but design complexity and manufacturing costs increase
Solution Approach 1:
The substrate is designed with a universal wiring pattern that can accommodate multiple USB connector types (USB 3.1 Type-A, USB 2.0 Type-A, and USB Type-C) through selective component mounting. The same substrate layout and wiring can support different USB standards by simply changing which connectors are mounted, eliminating the need for separate design files and reducing design complexity while maintaining multi-standard support
2Adaptability or versatility
If separate components and testing are used for different USB types, then each USB standard can be properly supported, but manufacturing costs increase
Solution Approach 1:
A single substrate design serves multiple USB connector types, allowing manufacturers to produce one base product that can be configured for different USB standards. This reduces per-unit costs by eliminating the need for separate design files, multiple substrate versions, and extensive re-testing for each connector type, while still providing adaptability to support USB 3.1 Type-A, USB 2.0 Type-A, and USB Type-C connectors
3Reliability
If separate testing is performed for different USB types, then each USB standard can be properly validated, but evaluation time and complexity increase
Solution Approach 1:
The universal substrate design allows a single evaluation process to validate multiple USB connector types. Since the wiring pattern and mounting structure are identical across different USB standards, testing performed on one connector type automatically validates the substrate's compatibility with other USB types, significantly reducing evaluation time and complexity while maintaining reliability of validation
4Ease of manufacture
If a common wiring pattern is used for different USB types, then manufacturing is simplified, but adaptability to different connector types must be maintained
Solution Approach 1:
The wiring pattern is designed to be universally compatible with multiple USB connector types (USB 3.1 Type-A, USB 2.0 Type-A, and USB Type-C) using the same trace routing and pad configurations. This allows the substrate to maintain adaptability to different connector types while simplifying manufacturing through a single, standardized wiring design that works across all supported USB standards
