Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find manual processes for opening hinged components in electronic devices, such as kickstands and display portions, to be frustrating and time-consuming.
Innovation Solution
The implementation of an electrical winding or coil in one part of the device and a magnet in the hinged component, where applying current to the winding generates a magnetic field that repels the magnet's field, allowing the hinged component to automatically open, and reversing the current causes it to close.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual processes are used to open hinged components, then device complexity is reduced, but user convenience and time efficiency deteriorate
Solution Approach 1:
The patent replaces manual mechanical operation with an electromagnetic actuation system. A magnet and electromagnetic coil combination automatically opens the hinged component when current is applied, eliminating the need for manual user interaction while accepting increased device complexity through the addition of electromagnetic components.
Solution Approach 2:
The hinged component system performs automatic opening and closing operations without requiring user intervention. The electromagnetic mechanism serves itself by using electrical current to actuate the hinge, reducing the need for manual service while incorporating electromagnetic components into the device.
2Extent of automation
If electromagnetic actuation is implemented to automate opening, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent implements automation by substituting manual mechanical operation with an electromagnetic field-based system. The magnet and coil combination creates automatic actuation when electrical current is applied, achieving high extent of automation while managing device complexity through efficient electromagnetic component integration.
3Productivity
If manual unlocking mechanism is used, then device complexity is minimized, but time consumption increases
Solution Approach 1:
The patent replaces time-consuming manual unlocking with rapid electromagnetic actuation. The magnetic field generation and collapse enables quick opening and closing operations, significantly improving productivity while accepting the addition of electromagnetic components to the device.
Solution Approach 2:
The electromagnetic actuation system uses periodic application and removal of electrical current to control the opening and closing of the hinged component. This periodic electromagnetic activation enables rapid cyclic operation, improving speed while managing device complexity through controlled electrical input.

Enables the hinged component to open and close automatically without user intervention, reducing manual effort and time, while maintaining electromagnetic interference protection.
Implementation Method 1
When current is applied to the electrical winding (e.g., in a direction opposite of the North/South direction of the magnets' magnetic field), the electrical winding may generate a magnetic field that repels the magnet's magnetic field. The magnetic repulsion may cause the hinged component to separate from the rest of the electronic device
Implementation Method 2
When current is applied to the electrical winding (e.g., in a direction opposite of the North/South direction of the magnets' magnetic field), the electrical winding may generate a magnetic field that repels the magnet's magnetic field

AI summary
The present disclosure is directed at automatically opening hinged components of computing devices. One of the computing devices and a hinged component may include an electrical winding or coil while the other may include a magnet. When current is applied to the electrical winding (e.g., in a direction opposite of the North/South direction of the magnets' magnetic field), the electrical winding may generate a magnetic field opposite that repels the magnet's magnetic field. The magnetic repulsion may cause the hinged component to separate from the rest of the computing device, thereby opening the hinged component. When the current is removed from the electrical winding, the electrical winding may no longer generate a magnetic field, enabling the hinged component to be closed.
