Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional system architecture is used in personal computers and notebook computers, then the system structure is simple and easy to manufacture, but the system cannot perform data communication with new communication protocols

Engineering Contradiction:
Improvecommunication protocol compatibilityVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mDP bus is designed to support multiple communication protocols (DisplayPort and Thunderbolt) through a single interface. The bus can dynamically switch between different protocols based on the connected device, allowing one physical interface to serve multiple communication standards without requiring separate dedicated buses for each protocol

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically switches between different communication protocols based on the connected device type. The host device can transition between DisplayPort mode and Thunderbolt mode by reconfiguring the mDP bus, enabling adaptive communication capability that responds to different peripheral equipment requirements

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If additional buses are added to support new communication protocols, then communication protocol compatibility is improved, but the device complexity and number of components increase

Engineering Contradiction:
Improvecommunication protocol compatibilityVSAvoidnumber of buses
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mDP bus serves as a universal interface that can handle both DisplayPort and Thunderbolt communication protocols. By designing the bus with multi-protocol support capability, the invention eliminates the need for separate dedicated buses for different communication standards, reducing the overall number of buses required in the system

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functionality of multiple communication protocols into a single mDP bus interface. Instead of having separate physical buses for DisplayPort and Thunderbolt communications, the system combines these protocols into one shared bus that can dynamically allocate resources and switch between protocols as needed

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An electronic system is provided, including a host electronic device and a first electronic device. The host electronic device is coupled to a mini display port (mDP) bus composed of a first lane and a second lane, in which the host electronic device turns off the second lane according to a disable signal in a first communication protocol mode. The first electronic device is coupled to the mDP bus and outputs a detection signal to the host electronic device, in which, when the first electronic device is coupled to the host electronic device, the host electronic device communicates with the first electronic device through the first lane in the first communication protocol mode and communicates with the first electronic device through the second lane in a second communication protocol mode, according to an enable signal.
