Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices face challenges in efficiently managing multiple connectors and ports, leading to issues with cost, aesthetics, and user flexibility, as users have varying preferences for peripheral device placement and workspace configurations.
Innovation Solution
Implementing multi-purpose ports with USB Type-C connectors that can operate in DisplayPort Alternate mode and high-speed USB data mode, using a reordering switch and multiplexers to dynamically route signals based on plug orientation, allowing for flexible placement and use of peripherals on either side of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate connectors are provided for different functions (display, data, power), then each connector can be optimized for its specific function, but the device complexity increases and aesthetic quality deteriorates due to multiple ports on the device housing
Solution Approach 1:
The patent implements a universal connector design where a single USB Type-C connector integrates multiple functions including display output (DisplayPort alternate mode), high-speed data transfer (USB 3.0/3.1 modes), and power delivery. The connector receptacle is configured to accept plugs from various peripheral devices (monitors, printers, mobile devices) and automatically routes appropriate signals based on the connected device type, eliminating the need for separate dedicated connectors for each function.
2Reliability
If multiple separate connectors are provided for different functions, then each connector can be optimized for its specific function, but the manufacturing cost increases due to additional components and assembly steps
Solution Approach 1:
The patent merges multiple separate connector assemblies into a single integrated USB Type-C connector receptacle. Instead of manufacturing and assembling separate connectors for display, data, and power functions, the design consolidates all these functions into one connector type, reducing component count, simplifying the assembly process, and lowering manufacturing costs while maintaining full functional capability through the universal connector's multi-mode operation.
3Device complexity
If connectors are fixed on specific sides of the device, then the device structure can be simplified, but user flexibility deteriorates as users cannot place peripherals according to their workspace preferences
Solution Approach 1:
The patent implements dynamic connector placement by positioning the USB Type-C connector receptacle on multiple sides of the device housing (front, rear, and/or side surfaces). This allows the connector to be accessible from different directions depending on the device's orientation and the user's workspace layout. The system dynamically adapts to user needs by enabling peripheral connections from any side, providing flexibility for various workspace configurations without requiring multiple dedicated connectors for each side.
4Device complexity
If a universal multi-function connector is implemented, then device aesthetics improve and complexity is reduced, but the ability to provide optimized signal routing for different functions becomes more difficult
Solution Approach 1:
The patent incorporates automatic detection and signal routing capabilities where the connector system detects the type of peripheral device connected (monitor, printer, mobile device) and automatically configures the appropriate signal routing. The system uses feedback from the connected device to determine which functions to activate (display output, data transfer, power delivery) and routes signals accordingly through the shared connector, eliminating the need for manual configuration while maintaining optimized signal paths for each function.
