Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw fastening means is used to attach the hard disk case to the rack, then the assembly is secure and stable, but the assembly process becomes time-consuming and requires hand tools
Solution Approach 1:
The patent extracts and eliminates the screw fastening mechanism from the assembly system. Instead of using screws to attach the hard disk case to the rack, the design employs a screw-free interface with positioning structures and elastic arms that provide secure attachment without requiring any screw fasteners, thereby eliminating the time-consuming assembly process while maintaining reliability
Solution Approach 2:
The elastic arm mechanism provides self-service functionality by automatically engaging with the rack structure when the hard disk case is inserted. The elastic arm's inherent elasticity enables automatic positioning and securing without requiring external hand tools or manual screw tightening, thus reducing assembly time while ensuring stable attachment
2Reliability
If numerous screws are used for fastening the hard disk case and rack, then the connection is strong and reliable, but the production cost increases due to additional screw purchasing costs
Solution Approach 1:
The patent removes the screw components entirely from the connection system between the hard disk case and rack. By replacing the screw-based fastening with an integrated elastic arm mechanism, the design eliminates the need to purchase and install numerous screws, thereby reducing production costs while maintaining connection strength through the elastic engagement mechanism
Solution Approach 2:
The patent merges the fastening function into the structural components themselves. The elastic arm is integrated as part of the hard disk case assembly, combining the positioning and fastening functions into a single integrated structure, thereby eliminating the need for separate screw fasteners and reducing overall production costs
3Reliability
If screw fastening is used for hard disk replacement, then the hard disk is securely fixed, but the disassembly and assembly process becomes complicated and inconvenient for frequent replacements
Solution Approach 1:
The elastic arm mechanism provides self-service by automatically engaging and disengaging from the rack structure through simple insertion and removal motions. This eliminates the need for complex screw tightening and loosening operations, making frequent hard disk replacements convenient while maintaining secure fixation through the elastic engagement
Solution Approach 2:
The elastic arm introduces dynamic characteristics to the fixation system. The elastic deformation allows the arm to adaptively engage with the rack structure during insertion and release smoothly during removal, providing both secure fixation and ease of operation for frequent replacements without the rigidity and complexity of screw fastening

AI summary
A screw-free removable hard disk case includes a carrier, a slide rail and a slide sheet. The carrier includes a first lateral plate and a second lateral plate which define an accommodation space, the first lateral plate is formed with an elastic arm disposed with an insertion pin; the slide rail is disposed at an outer side of the first lateral plate, and formed with a slide groove corresponding to the elastic arm; the slide sheet is combined between the slide rail and the first lateral plate with a sliding means and exposed in the slide groove, the insertion pin is pressed by the slide sheet for being inserted in a lock hole correspondingly formed on a hard disk, so that the hard disk can be combined in the accommodation space through the insertion pin and the lock hole being mutually buckled.
