Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting of magnets on middle frames in foldable electronic devices occupies significant space, reducing the utilization of internal components and affecting the arrangement of other electronic components.
Innovation Solution
The magnets are integrated onto the electronic components themselves, with recesses and adhesive grooves to secure them in place, reducing the overall thickness and improving structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are mounted on the middle frame to maintain folded state, then mechanical feel and secure connection are improved, but space utilization is reduced due to large magnet volume and required clearance distances
Solution Approach 1:
The patent merges the magnet with the electronic component by disposing the magnet on the electronic component rather than separately mounting it on the middle frame. This integration eliminates the need for separate magnet mounting space and reduces the required clearance distance, as the magnet becomes part of the electronic component assembly.
Solution Approach 2:
The patent implements nesting by placing the magnet within or on the electronic component structure. The electronic component serves as the container or carrier for the magnet, allowing the magnet to occupy space that would otherwise be unused or require additional clearance, thereby improving overall space utilization.
2Ease of operation
If magnets are mounted on the middle frame with required clearance, then mechanical feel during folding is improved, but the distance between electronic component and magnet reduces space for component arrangement
Solution Approach 1:
The magnet is merged with the electronic component, eliminating the clearance gap that would otherwise be required between separately mounted magnets and electronic components. This integration maintains the mechanical feel during folding while maximizing the available area for component arrangement.
3Reliability
If larger magnets are used to improve magnetic attachment, then secure connection in folded state is improved, but space occupied by magnet and electronic component increases
Solution Approach 1:
By integrating the magnet with the electronic component, the patent allows for larger magnet volumes without proportionally increasing the overall space occupied. The magnet utilizes the volume of the electronic component assembly, making the increased magnet size more space-efficient while maintaining or improving magnetic attachment strength.

AI summary
This application relates to a foldable electronic device including a first middle frame, a second middle frame, an electronic component, and a magnet assembly. The second middle frame is rotatably connected to the first middle frame, the electronic component is disposed on the first middle frame or the second middle frame, the first middle frame and the second middle frame are magnetically attached to each other via the magnet assembly, the magnet assembly includes a first magnet, and the first magnet is disposed on the electronic component, so that there is only a distance of a gap between the first magnet and the electronic component, reducing space occupied by the first magnet and the electronic component in a first direction and a second direction in the foldable electronic device, and improving utilization of space inside the foldable electronic device, for the first magnet or the electronic component to have more mounting space in the first direction and the second direction. In this way, a volume of the first magnet or the electronic component can be designed to be larger, to improve performance of the first magnet or the electronic component, improving user experience.
