Electronic Fastener Neck-and-Shoulder Structure for Modular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for arranging and assembling components in electronic devices are inefficient, leading to complications in connecting components within the housing and risking damage during component removal or replacement.
Innovation Solution
A fastener system with a body, shoulder, and neck structure, where the shoulder provides compressive force to retain a first component, and a second component connects to the neck, allowing for independent attachment and detachment without disturbing the first component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening methods are used to secure components in electronic devices, then components are retained in position, but assembly and disassembly become complicated and time-consuming
Solution Approach 1:
The fastening system is segmented into distinct functional portions: a fastener with head, body, and neck portions, and a separate bracket with retention mechanisms. This segmentation allows independent assembly and disassembly of components, simplifying the overall process while reducing system complexity through modular design.
Solution Approach 2:
The neck portion of the fastener serves as an intermediary element between the head and the bracket's retention mechanisms. This intermediary structure enables the bracket to engage with and retain the fastener independently, facilitating easier assembly and disassembly while maintaining system integrity.
2Volume of moving object
If components are tightly packed in stacks with little space between them, then device volume is reduced, but connecting and assembling components becomes complicated
Solution Approach 1:
The fastening system employs a nested structure where the bracket's retention mechanisms engage with the neck portion of the fastener, which is itself attached to the head. This nesting arrangement allows multiple components to be securely connected in a compact stack configuration, reducing device volume while maintaining simple connection mechanisms.
3Stability of the object's composition
If components are securely retained in position, then stability is improved, but removal and replacement of components risks damage
Solution Approach 1:
The fastening system provides dynamic retention where the bracket can be easily attached and detached from the fastener's neck portion. This dynamic design maintains stable component positioning during operation while enabling safe removal and replacement without risking damage to the components themselves.

AI summary
A fastener (100) for retaining a plurality of components (334, 348) in an electronic device includes a body (102) with a bottom end and a top end, where the bottom end includes a mechanical interlocking feature (104) integrally formed with the bottom end and the top end includes a head (106) integrally formed with the top end. Between the head (106) and the mechanical interlocking feature (104), the body includes an integrally formed shoulder (108). A neck (110) is positioned between the shoulder (108) and the head (106) with a neck outer diameter that is less than a head outer diameter and a shoulder outer diameter.
