Upright M.2 Connector with Integrated Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current M.2 module installation methods require significant PCB real estate and necessitate PCB redesign for different module lengths, as modules are typically installed flat, using attachment screws which limit flexibility and increase manufacturing costs.
Innovation Solution
A universal M.2 connector solution that allows modules to be installed in an upright orientation using a connector component with integrated retention mechanisms, such as friction, clamps, or locking mechanisms, eliminating the need for external screws and accommodating various module lengths without PCB redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If M.2 modules are installed flat on PCB using attachment screws, then secure retention is achieved, but PCB real estate is significantly consumed and flexibility is limited
Solution Approach 1:
The patent transitions from horizontal flat mounting to vertical upright mounting of M.2 modules. This dimensional change allows modules to be positioned perpendicular to the PCB surface, dramatically reducing the horizontal footprint on the PCB while maintaining secure retention through the connector component's integrated retention mechanism.
2Reliability
If attachment screws are used for module retention, then secure fixation is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent integrates the retention function directly into the connector component, combining what were previously separate functions (connector and retention mechanism) into a single unified component. This eliminates the need for separate attachment screws and reduces overall device complexity while maintaining secure module fixation.
Solution Approach 2:
The connector component's retention mechanism is designed to automatically engage and retain the M.2 module without requiring separate fastening operations. The integrated retention feature provides self-contained fixation functionality, eliminating the need for additional screws or external retention components.
3Manufacturing precision
If PCB is designed for specific module lengths, then precise fit is achieved, but adaptability to different module lengths is reduced
Solution Approach 1:
The patent designs the connector component with universal compatibility to accommodate multiple M.2 module lengths (2230, 2242, 2260, 2280, 22110). The connector's retention mechanism and interface are configured to work with various module dimensions, allowing a single PCB design to support different module types without requiring redesign for each specific length.
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
This solution reduces the connector/module PCB footprint, enables multiple modules to share space, decreases component count, and lowers manufacturing costs by eliminating attachment screws, while maintaining secure module retention.
Implementation Method 1
The connector component may receive and retain the M.2 module based on only a friction force between the connector component and the M.2 module

AI summary
In one example in accordance with the present disclosure, a connector component is provided. The connector component includes a first connector portion comprising a plurality of contacts to couple with a printed circuit board, and a second connector portion comprising a plurality of contacts to couple with an M.2 form factor module. The second connector portion is to receive the M.2 form factor module in an upright orientation such that neither a front surface nor a rear surface of the M.2 form factor module substantially faces the printed circuit board. In addition, the second connector portion is to retain the M.2 form factor module in the upright orientation without a retention mechanism external to the connector component.
