Modular I/O Interface Assembly for Motherboard Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Thunderbolt 3 interface designs require additional space on the motherboard for electrical connectors and driving chips, and the increasing performance requirements of graphics cards make it inconvenient to install them in the PCI-E slot, limiting motherboard expandability.
Innovation Solution
An input/output transmission interface assembly is designed with a first and second circuit board, each equipped with electrical connectors and a driving chip, connected via a board-to-board connector, allowing these components to be removed from the motherboard and mounted on an independent circuit board, which can be plugged into the PCI-E slot, thereby freeing up space and enhancing motherboard flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connectors and driving chips are directly welded on the motherboard, then connection reliability is improved, but motherboard space is increased
Solution Approach 1:
The patent divides the motherboard into functional modules by separating electrical connectors and driving chips onto independent circuit boards (first and second circuit boards). These modules can be independently assembled and replaced, reducing the space required on the main motherboard while maintaining connection reliability through standardized board-to-board connectors.
Solution Approach 2:
The patent transitions from a two-dimensional layout where all components are welded directly on the motherboard surface to a three-dimensional modular architecture. Circuit boards are stacked vertically and connected through board-to-board connectors, utilizing the vertical dimension to reduce footprint while maintaining all necessary electrical connections.
2Power
If graphics card is installed in the PCI-E slot to meet performance requirements, then graphics performance is improved, but motherboard expandability is reduced
Solution Approach 1:
The patent creates a universal interface system where the first and second circuit boards can support multiple types of transmission interfaces (Thunderbolt 3, USB 3.2, Mini DisplayPort, DisplayPort). This modular design allows the same physical slot to accommodate different interface types and configurations, enhancing motherboard versatility without sacrificing graphics performance capability.
3Adaptability or versatility
If multiple transmission interfaces are integrated on the motherboard, then interface compatibility is improved, but device complexity is increased
Solution Approach 1:
The patent segments different transmission interface types onto separate circuit boards (first circuit board for Thunderbolt 3/USB 3.2, second circuit board for Mini DisplayPort/DisplayPort). Each board is dedicated to specific interface types, simplifying the design and assembly process while providing comprehensive interface compatibility through modular integration.

AI summary
An input/output transmission interface assembly capable of being assembled on a motherboard includes a first transmission interface, a board-to-board connector, and a second transmission interface. The first transmission interface includes a first circuit board, a first electrical connector, a driving chip, and a plug portion. The plug portion is at one side of the first circuit board for being plugged into the motherboard. The second transmission interface includes a second circuit board and a second electrical connector. The second circuit board is substantially parallel to the first circuit board. The board-to-board connector is assembled on and between the first circuit board and the second circuit board. The first circuit board and the second circuit board are electrically connected with each other through the board-to-board connector.
