Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the magnetic rack to the chassis, then the connection strength is improved, but the assembly and disassembly time increases
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with a magnetic fastening system. The magnetic rack includes magnetic components that can be attracted to corresponding magnetic components on the chassis, enabling secure connection without screws. This substitution eliminates the time-consuming screw insertion and removal process while maintaining adequate connection strength through magnetic attraction force.
Solution Approach 2:
The magnetic fastening system allows for dynamic assembly and disassembly operations. The magnetic connection can be quickly engaged by simply placing the magnetic rack against the chassis, and equally easily removed by pulling away. This dynamic characteristic contrasts with the static, permanent fastening provided by screws, enabling rapid assembly and disassembly without compromising connection integrity during normal operation.
2Reliability
If screws are used to fix the magnetic rack, then the fixation reliability is improved, but the operational convenience deteriorates
Solution Approach 1:
The patent substitutes the screw-based mechanical fastening system with a magnetic fastening system. The magnetic rack includes magnetic components that can be attracted to corresponding magnetic components on the chassis, enabling secure connection without screws. This substitution eliminates the time-consuming screw insertion and removal process while maintaining adequate connection strength through magnetic attraction force.
Solution Approach 2:
The magnetic fastening system enables self-aligning and self-securing assembly. When the magnetic rack is brought near the chassis, the magnetic attraction automatically draws the components together and maintains them in the correct position, eliminating the need for precise screw alignment and manual fastening operations. This self-service characteristic significantly improves operational convenience while maintaining fixation reliability.
3Ease of manufacture
If a magnetic rack with sliding shafts and notches is used, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The magnetic rack is segmented into distinct functional components: magnetic components for attachment, sliding shafts for positional adjustment, and notches for orientation and locking. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process. The sliding shafts can be independently positioned within the notches, and the magnetic components can be separately attached, making the assembly process more manageable despite the increased number of parts.
Solution Approach 2:
The sliding shafts and notches mechanism serves multiple functions simultaneously: it provides positional adjustment, orientation guidance, and locking/positioning stability. This multi-functionality reduces the need for separate components for each function, thereby managing device complexity while maintaining ease of assembly. The same sliding shaft and notch structure that guides the rack into position also secures it in place.

AI summary
A housing of a computer host housing with a fixing for disk drives which is fastener-free includes a chassis and a magnetic rack. The chassis includes bottom shell, and first and second side shells. Ends of the first and second side shells define a first notch and a first sliding groove. The first sliding groove communicates with the first notch, the end of the first side shell defines a second notch and a second sliding groove. The second sliding groove communicates with the second notch. The magnetic rack includes first and second sidewalls. A first shaft and a second shaft protrude from the first sidewall, another first shaft protrudes from the second sidewall. The two first shafts and the second shaft can slide from the notches into the sliding grooves to secure or to allow the release of the disk drives.
