Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components with large volume (hard disk drive, optical disk drive, graphic card) are omitted to reduce computer volume and weight, then portability and compactness are improved, but storage capacity and graphic processing capabilities are reduced
Solution Approach 1:
The computer system is divided into a compact main body and separable expansion devices. The main body contains only essential components for portability, while expansion devices (hard disk drive, optical disk drive, graphic card) can be attached separately when needed, resolving the contradiction between compactness and functionality.
Solution Approach 2:
The computer system transitions from a static fixed configuration to a dynamic reconfigurable system. Expansion devices can be attached or detached based on application requirements, allowing the system to adapt between compact portable mode and expanded functional mode.
2Weight of moving object
If components are omitted to reduce computer volume, then portability is improved, but storage capacity and multimedia capabilities are reduced
Solution Approach 1:
Storage functionality is segmented into a separate expandable hard disk drive device that can be attached to the compact computer body. This allows the main computer to remain lightweight while providing access to large-capacity storage when the expansion device is connected.
3Device complexity
If the computer structure is simplified to reduce volume, then manufacturing complexity is reduced, but the ability to support advanced applications is reduced
Solution Approach 1:
The expansion bus interface is designed as a universal connection standard that can support multiple types of expansion devices (storage, optical drive, graphic card). This simple yet universal interface enables the compact computer to achieve advanced application capabilities through device attachment without complicating the internal structure.

AI summary
An expandable computer system and a fastening device are disclosed in this invention. The expandable computer system includes a computer, an expansion device and a rigid component. The expansion device includes a first holding portion disposed at a first side of the expansion device, and a first interface socket disposed at a second side of the expansion device. The computer includes a second holding portion and a second interface socket. The rigid component has two transmission plugs and a transmission circuit. The two transmission plugs are coupled with two terminals of the transmission circuit. When the first holding portion is connected with the second holding portion, the two transmission plugs are detachably connected with the first interface socket and the second interface socket to fasten the expansion device to the computer.
