Sliding Clamp Retainer for Tool-Free M.2 Card Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening mechanisms for M.2 solid state drives require tools for assembly, are space-inefficient, and increase manufacturing costs due to the need for embedded screws and bolts, while existing latches are complex and wear down the mounting surface.
Innovation Solution
A retaining mechanism with a seat and sliding clamp member that allows tool-free attachment to a substrate, featuring a beveled guide surface for easy card retention and release, and a simplified structure that minimizes space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and bolts are used to fasten solid state drives to the motherboard, then the fastening is secure and reliable, but the assembly and disassembly process becomes complicated and time-consuming, and manufacturing cost increases
Solution Approach 1:
The fastening mechanism is divided into a clamp body with a sliding clamp member that can independently move to secure the electronic card, separating the fastening function from the mounting structure
Solution Approach 2:
The sliding clamp member uses an elastic section to automatically return to its original position after being pressed, enabling self-service operation without requiring external tools or power sources
2Strength
If screws and bolts are embedded in the motherboard for fastening, then the fastening strength is sufficient, but the manufacturing cost increases
Solution Approach 1:
The fastening function is extracted from the motherboard structure itself and implemented through a separate clamp member that slides to secure the electronic card, eliminating the need for embedded screws and bolts in the motherboard
Solution Approach 2:
The clamp member uses a simple elastic deformation mechanism instead of expensive embedded fasteners, reducing material cost while maintaining sufficient fastening strength for the application
3Reliability
If a latch mechanism is used for retention, then the electronic card can be securely held, but the structure becomes complex and may wear down the mounting surface
Solution Approach 1:
The retention function is extracted from a complex latch mechanism and implemented through a simple sliding clamp member that uses elastic deformation to hold the electronic card in place
Solution Approach 2:
The mechanical latch system is replaced with an elastic deformation system where the sliding clamp member is pressed backward to release and automatically returns to retain the card through elastic recovery
4Reliability
If a tool-operated fastening mechanism is used, then the fastening can be secure, but the ease of operation decreases and requires additional tools
Solution Approach 1:
The fastening mechanism operates through direct manual pressure on the sliding clamp member which automatically returns via elastic force, making it self-service and eliminating the need for external tools
Solution Approach 2:
Instead of using a tool to turn or manipulate a fastening mechanism, the user directly presses the clamp member backward and the elastic force automatically reverses the action to secure the card
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
Enables quick, tool-free mounting and dismounting of electronic cards, reduces manufacturing costs, and maintains compactness without surface wear, enhancing operational convenience and efficiency.
Implementation Method 1
the sliding clamp member is movable backward toward the inner stop surface to compress and deform the curved elastic section, so that the sliding clamp member stores an elastic force for moving away from the inner stop surface

AI summary
A retaining mechanism includes an open topped seat having a rear inner stop surface and two lateral guide sections; and a sliding clamp member received in the seat and including mating guide sections slidably engaged with the guide sections and a rear curved elastic section having a free end pressing against the inner stop surface. The sliding clamp member further includes a front pressing section having a beveled guide surface on an upper front thereof. The sliding clamp member is movable toward the inner stop surface to elastically deform the curved elastic section when an electronic card is pressed downward against the beveled guide surface, such that the sliding clamp member stores an elastic force and can automatically spring forward to retain the electronic card in place when the electronic card passes over the pressing section. The electronic card can be released simply by pushing the sliding clamp member backward.
