Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If extension cards are installed in the computer to provide additional functions, then the computer functionality is enhanced, but the extension cards occupy limited space and may interfere with each other
Solution Approach 1:
The system is divided into two separate units: a host computer and an external function extension device. The function extension card is relocated from the host computer's internal slot to an external device that connects via USB interface. This segmentation allows the host computer to maintain its compact form factor while the external device houses the extension card, thus resolving the space occupation problem while preserving functionality enhancement.
2Adaptability or versatility
If function extension cards are installed to enhance computer functions, then additional capabilities are provided, but heat is generated due to impedance and may damage electronic components if not dissipated
Solution Approach 1:
A liquid cooling system is introduced as an intermediary between the function extension card and the external environment. The cooling system includes a cold plate that contacts the extension card to absorb heat, cooling liquid that circulates through the cold plate to transfer heat away, and a radiator with fan that dissipates heat to the atmosphere. This intermediary cooling mechanism effectively manages the heat generated by the extension card's impedance, preventing component damage while maintaining the card's operational functionality.
3Adaptability or versatility
If multiple extension cards are installed in limited space, then various functions are provided, but the cards may interfere with each other
Solution Approach 1:
The function extension card is moved from the internal dimension (inside the host computer) to an external dimension (separate external device connected via USB). This dimensional transition eliminates physical interference between multiple cards that would occur if they were installed in the same confined internal space. Users can now connect multiple external function extension devices without the cards interfering with each other, as each card operates in its own external housing with adequate spacing.
