Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and bolts are used to fasten M.2 solid state drives to the motherboard, then the solid state drive can be securely retained, but the manufacturing cost increases and assembly/disassembly becomes labor-intensive
Solution Approach 1:
The retaining member is designed to automatically engage with the electronic card through elastic deformation. When the electronic card is inserted, the retaining member elastically deforms and self-locks into position without requiring external tools or manual fastening operations, enabling tool-free assembly and disassembly
Solution Approach 2:
The retaining member transitions from a static fastening structure to a dynamic elastic component that can deform and recover. The elastic arm bends and returns to its original shape during the retention process, providing automatic engagement and release capabilities that eliminate the need for screws and bolts
2Reliability
If screws and bolts are used to fasten M.2 solid state drives, then secure retention is achieved, but assembly and disassembly operations become labor-consuming
Solution Approach 1:
The retaining member performs the fastening function automatically through elastic deformation and self-locking mechanisms. Users simply insert and remove the electronic card without needing to manually tighten or loosen fasteners, significantly reducing assembly and disassembly labor
Solution Approach 2:
The invention extracts and eliminates the need for screws, bolts, and associated fastening tools from the assembly process. The retaining member integrates all necessary fastening functions into a single elastic component, removing complex multi-step fastening operations
3Reliability
If bolts are embedded in the motherboard for screw fastening, then secure retention is possible, but the manufacturing cost increases
Solution Approach 1:
The invention removes the requirement for embedded bolts and corresponding screw holes from the motherboard design. The retaining member functions as a self-contained fastening system that engages with the electronic card without modifying the motherboard structure
Solution Approach 2:
The fastening function is segmented from the motherboard structure and placed in a separate retaining member component. This allows the motherboard to remain simple while the retaining member provides the necessary fastening capabilities through elastic deformation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides easy operation, secure retention, and reduced production costs, eliminating loose connections and facilitating efficient installation and removal of electronic cards like solid state drives.
Implementation Method 1
the elastic arm is stopped by the stopper section to become elastically deformed and store an elastic restoring force; and when the movable retaining member is released from the external force applied thereto, the elastic arm is driven by the stored elastic restoring force to displace the movable retaining member from the release position back to the electronic card retaining position

AI summary
An electronic card retaining device includes a seat mounted on a motherboard and a movable retaining member. The seat is provided with a stopper section and a guide section; the movable retaining member has an elastic arm corresponding to the stopper section and a mating guide section for engaging with the guide section. When the movable retaining member is assembled to the seat, the elastic arm can be pressed against the stopper section and elastically deformed; and the guide section and the mating guide section can engage with each other to guide the movable retaining member to elastically displace on the seat relative to an electronic card between a retaining position and a release position. With the above arrangements, the electronic card retaining device so formed is structurally simplified and easily operable for conveniently, securely and elastically retaining or releasing the electronic card to or from the motherboard.
