Magnetic Attachment for Electronic Components in Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of screws to attach electronic components, such as circuit boards, in electronic devices leads to long manufacturing cycle times, high re-work costs, and scrap costs due to screw stripping and the need for complete detachment for re-work.
Innovation Solution
Electronic components are magnetically attached to the internal surface of the housing using magnetic forces, eliminating the need for screws and allowing for easier re-work by applying a force to detach the component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to attach electronic components to the housing, then a robust and secure connection is achieved, but manufacturing cycle time increases and re-workability decreases
Solution Approach 1:
The patent replaces the mechanical screw-fastening system with a magnetic attachment system. Magnets are embedded in the housing to provide secure attachment of electronic components without requiring screws, thereby eliminating the time-consuming screw installation process while maintaining connection strength.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (screws) to magnetic field-based. By embedding magnets in the housing, the attachment method transitions from threaded mechanical fastening to magnetic attraction, fundamentally changing how components are secured and enabling faster assembly and re-workability.
2Strength
If screws are used to attach the motherboard, then a secure connection is achieved, but re-work costs increase due to complete detachment requirement
Solution Approach 1:
The magnetic attachment system replaces screw fastening, allowing components to be detached by simply overcoming the magnetic force rather than removing multiple screws. This enables partial re-work of components without complete detachment, significantly improving ease of repair and reducing re-work costs.
3Strength
If screws are used for component attachment, then a firm connection is achieved, but scrap costs increase due to screw stripping
Solution Approach 1:
By replacing screw fastening with magnetic attachment, the patent eliminates the risk of thread stripping in the housing. Magnets provide firm connection without penetrating or threading into the housing material, thereby preventing the damage that leads to scrap and high disposal costs.

AI summary
An electronic device with a magnetically attached electronic component is described herein. An electronic device includes a housing and an electronic component. The electronic component is positioned within the housing and magnetically attached to an internal surface of the housing via a magnetic force between the electronic component and the internal surface of the housing. During manufacturing, the electronic component can be magnetically attached to the internal surface of the housing by aligning one or more magnetic attachment points of the electronic component within magnetic proximity to one or more corresponding magnetic attachment points of the internal surface of the housing of the electronic device to magnetically attach the electronic component to the internal surface of the housing.
