Solution Overview
Problem
Electronic apparatuses with optical devices, such as cameras, face design integrity issues due to exposure and require a mechanism that provides a stable click feeling and long lifespan while minimizing bezel width and weight.
Innovation Solution
A slide mechanism with a movable slider and magnet configuration that allows the optical device to be shielded or exposed, utilizing a movable magnet and fixed magnet interaction for stable operation and assembly, providing a click feeling through magnetic resistance and minimizing weight and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a mechanical shutter is used to cover the camera, then design integrity is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical springs and complex mechanical structures with a magnetic field-based positioning system. Magnets are embedded in the slider and housing to provide attraction/repulsion forces for positioning and click feedback, eliminating the need for mechanical springs and reducing overall mechanical complexity while maintaining the shielding function.
2Reliability
If a magnetic positioning system is used, then reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a dynamic magnetic positioning system where magnets in the slider interact with magnets in the housing to provide position-dependent forces. The system uses magnetic attraction at desired positions and magnetic repulsion to prevent unintended activation, creating a self-stabilizing mechanism that maintains reliability while being tolerant to manufacturing variations through the distributed magnetic field interactions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism ensures a stable and intuitive operation with a long lifespan, maintaining design integrity and user comfort by providing a clear optical path when needed and shielding the camera when not in use, while being easy to assemble and reducing mechanical complexity.
Implementation Method 1
The movable magnet and the fixed magnet are disposed to face each other so that when the slider is in the first position and the second position, the movable magnet and the fixed magnet attract to each other, and when the slider is located between the first position and the second position, the movable magnet and the fixed magnet repel each other

AI summary
A slide mechanism includes: a slider that is movable between a first position and a second position along an edge wall; a shield cover on the slider, the shield cover being located to cover the front of the camera when the slider is in the first position and located to be away from the front of the camera when the slider is in the second position; a movable magnet at the slider; and a fixed magnet at the chassis. The movable magnet and the fixed magnet are disposed to face each other so that when the slider is in the first position and the second position, the movable magnet and the fixed magnet attract to each other, and when the slider is located between the first position and the second position, the movable magnet and the fixed magnet repel each other.
