Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical USB3 device connector is used, then secure mating with host connector is achieved, but device size increases and manufacturing complexity increases
Solution Approach 1:
The patent merges the USB3 device connector functionality directly into the USB device main body, eliminating the need for a separate physical connector. The connector interface is integrated into the housing of the USB device, combining what were previously separate components (main body and connector) into a single unified structure, thereby reducing device complexity while maintaining secure mating capability
Solution Approach 2:
The USB device main body is designed to serve multiple functions: it houses the electronic circuitry and simultaneously provides the connector interface for mating with host connectors. This multi-functional design allows the main body to replace the traditional dedicated connector component, reducing overall device complexity while maintaining connection reliability
2Reliability
If a physical USB3 device connector is used, then secure mating with host connector is achieved, but manufacturing cost increases and yield decreases
Solution Approach 1:
By integrating the connector interface into the USB device main body housing, the patent eliminates the need for separate connector assembly and soldering operations. The connector features are molded directly into the housing during the main body manufacturing process, simplifying manufacturing to a single molding operation and improving yield by eliminating the additional reflow soldering step
Solution Approach 2:
The patent extracts the connector functionality from the separate physical USB3 device connector and embeds it directly into the main body housing. This extraction eliminates the need for the complex soldering process that would otherwise be required to attach a separate connector, thereby improving ease of manufacture and increasing production yield
3Area of stationary object
If USB3 device connector functionality is extended into the main body, then connector space is eliminated, but achieving secure mating becomes more difficult
Solution Approach 1:
The patent applies local quality by creating a specialized recessed region within the USB device main body housing that is specifically designed for connector functionality. This local modification provides the necessary geometry for secure mating (including pin alignment and engagement features) while the rest of the housing maintains its primary structural and circuitry-housing functions, thus achieving secure mating without requiring a separate dedicated connector component
