Integrated M.2 WLAN Holder for Fast PCB Assembly and Cable Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of M.2 WLAN cards to a printed circuit board is complex, time-consuming, prone to failures, and costly due to the need for multiple parts and precise alignment of coaxial cables, which can lead to damage if not correctly installed.
Innovation Solution
A single-piece M.2 device holder with integrated standoff and cover portions, featuring a strap for secure attachment to the PCB, ensures proper alignment and retention of coaxial cables, reducing the part count and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate parts are used for M.2 device holder assembly, then the retention and alignment can be achieved, but the assembly complexity increases and assembly time exceeds 100 seconds
Solution Approach 1:
The patent combines multiple separate components (holder body, retention mechanism, alignment features) into a single integrated M.2 device holder assembly. This merging eliminates the need for multiple separate parts while maintaining the retention and alignment functions, directly resolving the contradiction between reliability and assembly complexity.
2Manufacturing precision
If precise alignment of coaxial cables is required, then proper connection is achieved, but the assembly process becomes time-consuming and prone to failures
Solution Approach 1:
The M.2 device holder assembly incorporates pre-formed alignment features and integrated coaxial cable routing that automatically guide cables into correct positions during installation. This preliminary preparation of alignment structures eliminates the need for time-consuming manual alignment adjustments, resolving the contradiction between manufacturing precision and time loss.
3Adaptability or versatility
If multiple parts are used in the holder assembly, then the functional requirements are met, but the part count increases and cost increases
Solution Approach 1:
The integrated M.2 device holder assembly is designed as a universal component that performs multiple functions simultaneously: mechanical retention, electrical connection, coaxial cable alignment, and structural support. This multi-functionality in a single part reduces the part count while meeting all functional requirements, resolving the contradiction between adaptability and quantity of substance.

AI summary
A device holder is provided for retaining an M.2 device to a printed circuit board. The device holder includes a standoff portion, a cover portion, and a strap configured to retain the standoff portion to the cover portion. The standoff portion is configured to be affixed to the printed circuit board and to provide a standoff upon which a first end of the M.2 device can be seated. The cover portion is configured, in an open position, to permit the insertion of a second end of the M.2 device into an M.2 connector, and, in a closed position, to retain the M.2 device to the standoff portion.
