Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing electronic devices during testing are unreliable, time-consuming, and prone to improper connections or disconnections due to the lack of effective fastening mechanisms, leading to increased testing time and costs.
Innovation Solution
The development of an electronic device fastener with a base link bar and corner retaining features that securely attach and detach the device from a testing board using existing mechanical attachment mechanisms, ensuring optimal positioning and preventing movement during testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives such as strips of tape are used to secure the electronic device, then the device can be kept from moving out of position, but the solution is unreliable, unrepeatable, and time consuming
Solution Approach 1:
The patent replaces adhesive-based securing mechanisms with a mechanical fastening system consisting of a fastener assembly that engages with mounting holes in the testing board. This mechanical system provides reliable and repeatable securing without the time-consuming application and removal processes associated with adhesives.
Solution Approach 2:
The fastening system is divided into separate components: a fastener assembly with mounting features that engages with pre-existing mounting holes in the testing board. This segmentation allows for quick attachment and detachment without affecting the entire testing system.
2Productivity
If mechanical attachment mechanisms are used to secure the electronic device, then the device can be quickly attached and detached, but the device may move or disconnect during handling
Solution Approach 1:
The patent combines multiple securing functions into a single integrated fastener assembly that simultaneously provides mechanical attachment through mounting holes and positional confinement through side walls and retaining features. This merging ensures both quick attachment and stable positioning during testing.
Solution Approach 2:
The fastener assembly acts as an intermediary between the electronic device and the testing board, providing a stable mechanical interface that prevents direct movement while allowing quick attachment and detachment. The side walls and retaining features mediate the positional relationship between device and board.
3Reliability
If a complex fastening system is implemented to prevent movement, then connection stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The fastener assembly is designed to engage with pre-existing mounting holes in standard testing boards, making it universally applicable without requiring custom modifications to the testing infrastructure. The same fastener design can be used across different testing scenarios and board configurations.
Solution Approach 2:
The fastening system utilizes pre-existing mounting holes in the testing board, eliminating the need for additional drilling or modification steps. The fastener assembly self-secures through these existing features, reducing manufacturing complexity while maintaining connection stability.

AI summary
Embodiments describe an electronic device fastener including a base link bar, and a pair of corner retaining features coupled to the base link bar. Each corner retaining feature includes a base being formed of a planar structure and having a base top surface, a support rail extending from a portion of the base top surface and having a support rail top surface, a fastening feature defined by surfaces of the base and support rail and comprising vacant space extending through the base and at least a portion of the support rail, a guide wall extending from a portion of the support rail top surface, a retaining protrusion extending from the guide wall toward a center line of the electronic device fastener, and a stopper positioned beside the base link bar and at back ends of the base, the support rail, the guide wall, and the base link bar.
