Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a KVM switch is integrated into a display to support multiple information handling systems, then the adaptability and versatility of the display increases, but the device complexity and setup difficulty increase
Solution Approach 1:
The KVM switch automatically detects cable types and configures itself without requiring manual user input. The system performs self-diagnosis and self-configuration by detecting which cables are connected and automatically setting up the appropriate interfaces, eliminating the need for users to manually configure each connection.
Solution Approach 2:
The system dynamically changes its operational parameters based on detected cable types. When different cable types are detected (USB-C, HDMI, DisplayPort, Cat 5), the KVM switch automatically adjusts its configuration parameters to match the appropriate interface requirements, allowing seamless adaptation without user intervention.
2Ease of operation
If the KVM switch automatically detects cable types and configures interfaces, then the ease of operation improves, but the processing requirements and device complexity increase
Solution Approach 1:
The KVM switch pre-loads multiple configuration user interfaces into its memory during manufacturing. These pre-configured interfaces are ready to be selected and presented to users based on the detected cable type, eliminating the need for runtime configuration generation and reducing processing requirements during setup.
Solution Approach 2:
The patent introduces a configuration user interface as an intermediary layer between the cable detection mechanism and the actual KVM switching functionality. This interface acts as a mediator that translates physical cable connections into appropriate system configurations, simplifying the overall architecture and distributing complexity across multiple manageable components.
3Adaptability or versatility
If multiple cable types are supported with different bandwidth capabilities, then the adaptability increases, but the difficulty of detecting and measuring cable characteristics increases
Solution Approach 1:
The patent segments the cable detection and configuration process into distinct, manageable steps. The system first detects cable presence, then identifies cable type, then selects the appropriate configuration interface, and finally applies the settings. This segmentation breaks down a complex detection task into simpler, sequential operations that are easier to implement and debug.

AI summary
A display keyboard video mouse (KVM) switch detects cables connected to ports of the display and compares the cable types against a configuration table to select a configuration user interface for presentation at the display retrieved from non-transitory memory of the display by a processing resource of the KVM switch. As an end user adjusts the cables connected to the display KVM switch, logic executing on the display adjusts the presentation of the configuration user interface to guide connections with plural information handling systems based upon the cable types and to confirm correct association of keyboard and mouse inputs through the KVM switch with each information handling system.
