Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connecting wires are exposed for easy access and maintenance, then ease of operation is improved, but safety deteriorates due to exposed electrical connections
Solution Approach 1:
The connection box serves as a nested enclosure that houses all electrical connections (power sources, controllers, signal interfaces) within a protected internal space. The power source interface and power source connection end are both extended into the connection box and connected via conducting bars, creating a nested arrangement where electrical components are contained within the box structure, eliminating exposed wires while maintaining accessibility.
Solution Approach 2:
The connection box acts as an intermediary element between the external environment and internal electrical connections. It provides a sealed interface where power and signal connections can be made safely, mediating between the need for accessible connections and the requirement for safety by containing all electrical interfaces within its enclosed structure.
2Object-affected harmful factors
If a sealed connection box is used to enclose electrical connections, then safety is improved, but device complexity increases due to additional enclosure structure
Solution Approach 1:
The connection box merges multiple functions into a single enclosure structure: it houses the power source interface, power source connection end, conducting bars, controller, and signal interfaces all within one integrated box. This consolidation reduces overall structural complexity compared to having separate enclosures for each electrical component while maintaining comprehensive safety coverage.
Solution Approach 2:
The connection box serves multiple functions simultaneously: it provides safety enclosure, houses electrical connections, supports the controller, and facilitates signal and power transmission. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while achieving comprehensive safety.
3Ease of repair
If computing apparatus can be easily removed for maintenance, then ease of repair is improved, but structural integrity deteriorates with frequent assembly/disassembly
Solution Approach 1:
The computing device is segmented into distinct functional modules: the computing apparatus (with computing board and heat sink) can be separated from the frame and connection box. This segmentation allows the computing apparatus to be easily removed for maintenance while the frame and connection box remain as stable structural elements, maintaining overall structural integrity through modular design.
Solution Approach 2:
The computing apparatus is designed with dynamic accessibility - it can be slid into or out of the frame through slide rails, transitioning between fixed and removable states. This dynamic design allows easy removal for maintenance when needed, while maintaining structural integrity when assembled, as the slide rail mechanism provides stable connection during operation.
