Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing M.2 SSDs on a main board require multiple holes, limiting wiring space and increasing product costs due to the need for additional layers to accommodate different SSD lengths.
Innovation Solution
A hard disk fixing device with a seating, elastic snap-fit members, adjusting fasteners, and a locking mechanism that allows for snap-fitting and adjustable positioning of SSDs, reducing the number of holes needed on the main board by using a single screw for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple holes are formed in the main board to support M.2 SSDs of various lengths, then the SSDs can be fixed securely, but the wiring space on the main board is limited and the number of layers must be increased, resulting in higher product cost
Solution Approach 1:
The patent moves the fixation mechanism from the main board plane to a vertical dimension by using a U-shaped bracket that clips onto the SSD from the side. This eliminates the need for multiple holes in the main board while providing secure fixation through the lateral clamping action of the bracket.
Solution Approach 2:
The U-shaped bracket serves as an intermediary component between the SSD and the main board. Instead of directly fixing the SSD to the main board through multiple holes, the bracket mediates the connection by clipping onto the SSD and attaching to a single hole in the main board, thereby simplifying the overall structure.
2Adaptability or versatility
If multiple holes are formed in the main board to accommodate different SSD lengths, then SSDs of various lengths can be supported, but the wiring space is reduced and additional layers are required, increasing product cost
Solution Approach 1:
The adjusting fastener mechanism allows the bracket to dynamically adapt to different SSD lengths. By adjusting the position of the fastener along the U-shaped bracket, the system can accommodate various SSD lengths without requiring different hole configurations in the main board, thereby simplifying manufacturing.
Solution Approach 2:
The single U-shaped bracket design with an adjustable fastener serves multiple functions: it can fix SSDs of different lengths, provide secure clamping, and attach to the main board through a single universal hole pattern. This multi-functional design eliminates the need for multiple specialized holes for different SSD types.
3Device complexity
If a single screw fixation method is used, then the number of holes on the main board is reduced, but the ability to securely fix SSDs of different lengths is compromised
Solution Approach 1:
The fixation system is segmented into three components: the U-shaped bracket that contacts the SSD, the adjusting fastener that provides clamping force, and the single screw that attaches to the main board. This segmentation allows each component to perform its specific function, ensuring secure fixation while minimizing holes in the main board.
Solution Approach 2:
The patent replaces the traditional mechanical screw-direct-to-SSD fixation with a clip-based mechanical system. The U-shaped bracket clips onto the SSD body, and the adjusting fastener provides clamping force, substituting the need for multiple screws while maintaining fixation security through mechanical interlocking.
