Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fasteners for electronic devices, such as M.2 solid state drives and Wi-Fi wireless network cards, are limited in design and cannot securely fasten multiple electronic devices simultaneously, leading to inefficient use of internal space and unstable electrical connections.
Innovation Solution
A fastener with a positioning unit and clamping member featuring non-round insertion holes, supporting concave parts, and a sliding cover mechanism, allowing for secure locking and unlocking of multiple electronic devices, along with anti-loosening and anti-rotation structures, to facilitate stable electrical connections and efficient space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional fastener with a single supporting concave part is used, then a single electronic device can be fastened securely, but multiple electronic devices cannot be fastened simultaneously, leading to inefficient space utilization
Solution Approach 1:
The fastener is divided into multiple independent clamping members, each with its own supporting concave part. The first clamping member has a first supporting concave part for fastening the first electronic device, while the second clamping member has a second supporting concave part for fastening the second electronic device. This segmentation allows multiple devices to be fastened simultaneously without increasing overall structural complexity
Solution Approach 2:
The fastener structure is designed with multiple supporting concave parts and clamping members that can universally accommodate different electronic devices. Each clamping member can independently fasten a different device type (e.g., M.2 solid state drive, Wi-Fi card, 3G card), making the single fastener structure multi-functional and adaptable to various device configurations
2Volume of moving object
If electronic devices are arranged in stacking manner to save space, then internal space utilization is improved, but electrical connection stability may be compromised without proper fastening
Solution Approach 1:
The positioning unit with positioning protrusions and positioning recesses is designed to pre-position the electronic devices in the correct stacking arrangement before final fastening. The positioning protrusions on the board member engage with positioning recesses on the devices, ensuring proper alignment and stable electrical connections are established before the clamping members apply fastening force
Solution Approach 2:
Multiple electronic devices are arranged in a nested stacking manner within the fastener structure. The first electronic device is fastened by the first clamping member, while the second electronic device is fastened by the second clamping member in an adjacent nested position. This nesting arrangement maximizes space utilization while maintaining individual fastening and electrical connection stability for each device
3Ease of manufacture
If a fastener design is simplified for easy manufacturing, then production cost is reduced, but the fastener cannot securely lock multiple electronic devices
Solution Approach 1:
Multiple clamping members are merged into a single integrated fastener structure that can be manufactured as one piece. The first clamping member with its clamping sheet and the second clamping member with its clamping sheet are combined in the same fastener body, allowing simultaneous fastening of multiple devices through a single manufacturing process while maintaining secure locking capability for each device
Solution Approach 2:
The clamping members are designed with asymmetric clamping sheets that have specific geometric shapes to engage with corresponding features on the electronic devices. The clamping sheets have irregular shapes with protrusions and recesses that provide secure mechanical interlocking, ensuring reliable fastening while maintaining manufacturing simplicity through standardized asymmetric design patterns

AI summary
A fastener for use in an electronic device includes a positioning unit and a clamping member. The positioning unit has a first supporting concave part allowing a first electronic device to be disposed, a fastening pin inserted in the positioning unit is disposed at a bottom end of clamping member, so that the bottom end of the clamping member enables the first electronic device to be in a locked status; the clamping member has a second supporting concave part allowing a second electronic device to be disposed, a chamber is at a location adjacent to one side of the second supporting concave part, and is connected to a sliding cover capable of radially and elastically sliding; with a front end of the sliding cover being released or be located above the second supporting concave part, the second electronic device can be in an unlocked status or a locked status.
