Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable connections are used to couple components in a server, then components can be connected and powered, but the assembly process becomes complicated and maintenance becomes difficult
Solution Approach 1:
The patent merges the power supply unit with the hard-disk backplane module, integrating power delivery directly at the component level. This eliminates the need for separate cable connections between power supplies and storage devices, simplifying assembly while maintaining reliable power and data connections through direct mechanical and electrical coupling
Solution Approach 2:
The tray structure is designed with universal functionality to accommodate different hard-disk configurations and support both power and data connections simultaneously. The integrated backplane module serves multiple functions: mechanical support, electrical connection, power distribution, and data transmission, reducing overall system complexity
2Reliability
If conventional cable connections are used inside a server, then components can be connected, but the cables interrupt air flow and negatively affect heat dissipation
Solution Approach 1:
The patent extracts and removes the cable connections from the server interior, eliminating the physical obstacles that disrupt airflow. By integrating power and data connections directly into the backplane module and tray structure, the design clears the air passage channels, allowing unobstructed airflow for effective heat dissipation while maintaining all necessary electrical connections
3Volume of stationary object
If components are tightly integrated in a limited server space, then space utilization improves, but assembly and disassembly become difficult
Solution Approach 1:
The patent segments the hard-disk storage system into modular components: individual hard-disk drives, a backplane module, and a tray assembly. This segmentation allows components to be tightly integrated within the server chassis for space efficiency while enabling easy assembly and disassembly by simply removing or inserting the entire tray module without complex cable management
Solution Approach 2:
The design employs a nested structure where hard-disk drives are mounted on the backplane module, which is integrated into the tray assembly, which in turn fits into the server chassis. This nested arrangement maximizes space utilization while maintaining operational ease through hierarchical modularity, allowing components to be accessed and replaced at appropriate levels

Function Achieved in This Case
The solution allows for simplified assembly and disassembly of electronic devices, enhancing reliability and heat dissipation by eliminating the need for cables and optimizing component alignment within the server.
Implementation Method 1
The grip pivots on the tray body and the slider. When the grip is in the first grip orientation, the tray body post is in a first tray post position relative to the slider post. When the grip is in the second grip orientation, the tray body post is in a second tray post position relative to the slider post.
