Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing screen occupancy ratio in terminals, such as full-screen mobile phones, compresses the space available for front cameras, leading to complex and space-consuming mechanical structures for pop-out camera modules.
Innovation Solution
A pop-out camera module utilizing a combination of coils and magnets, where n coils are positioned between a first and second magnet, generating electromagnetic fields to drive the camera housing to pop-out or pop-back, reducing structural complexity and space occupation compared to mechanical devices like motors and gear sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mechanical devices such as motors, gear sets, and lead screws are used to realize the pop-out camera module, then the camera can be moved between pop-out and pop-back states, but the structure becomes complicated and occupies large space
Solution Approach 1:
The patent replaces traditional mechanical driving devices (motors, gear sets, lead screws) with an electromagnetic driving system consisting of coils and magnets. The coils generate electromagnetic fields that interact with the magnets to produce linear driving force, eliminating the need for complex mechanical transmission components and significantly reducing structural complexity and space occupation.
Solution Approach 2:
The patent extracts and eliminates unnecessary mechanical transmission components from the system. By using electromagnetic direct driving, the design removes intermediaries such as gears, belts, and linkages, keeping only the essential elements (coils, magnets, and camera housing) needed to achieve the pop-out function.
2Area of stationary object
If the screen occupancy ratio is increased in full-screen mobile phones, then the display area is improved, but the space available for the front camera on the front panel is continuously compressed
Solution Approach 1:
The patent transitions the camera module from a static two-dimensional planar arrangement to a three-dimensional pop-out structure. By adding the depth dimension through electromagnetic linear driving, the camera can move between retracted and extended positions, allowing the front panel to maintain a full-screen appearance while accommodating the camera in the third dimension.
Solution Approach 2:
The camera housing is nested within the module housing in a retracted state, and can be extended outward when needed. This nested arrangement allows the camera module to occupy minimal space during normal operation while providing full camera functionality when popped out, effectively resolving the space conflict caused by increased screen occupancy.

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 electromagnetic interaction between coils and magnets simplifies the camera module's structure, saving space and reducing complexity while enabling efficient pop-out and pop-back functionality.
Implementation Method 1
the n coils generate a first electromagnetic field combination to push the camera housing to pop-out from the module housing under driving of the first magnet and the second magnet; and during the pop-back of the camera housing, the n coils generate a second electromagnetic field combination to pull the camera housing to pop-back into the module housing under the driving of the first magnet and the second magnet
