Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with sliding structures face challenges in minimizing the protrusion of rear camera modules and ensuring smooth sliding motions without interference with the display.
Innovation Solution
The electronic device incorporates a first structure and a second structure that slide relative to each other, with the display moving together, and includes rear camera modules arranged in a row and overlapping the front camera module to minimize protrusion, along with a circuit board structure for improved mountability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the rear camera module is made larger to improve imaging performance, then the imaging capability is improved, but the protrusion degree increases and may interfere with the display during sliding motion
Solution Approach 1:
The patent applies nesting by placing the rear camera module inside the space occupied by the front camera module. Specifically, the rear camera module is positioned within the projection area of the front camera module along the thickness direction, allowing the rear camera to be nested within the front camera's spatial envelope. This eliminates additional protrusion while accommodating both camera modules with improved imaging capabilities.
Solution Approach 2:
The patent transitions from two-dimensional camera arrangement (side-by-side or stacked on the same plane) to three-dimensional arrangement by utilizing the thickness direction. The rear camera module is positioned at a different depth along the Z-axis (thickness direction) relative to the front camera module, creating a layered configuration that reduces protrusion while maintaining imaging performance.
2Area of stationary object
If the sliding structure is designed to expand the display area, then the display area is expanded, but the rear camera module may interfere with the display during sliding motion
Solution Approach 1:
The patent extracts the rear camera module from the sliding path area by positioning it within the front camera module's projection. This separation removes the potential source of interference (rear camera) from the harmful interaction zone (display sliding path), allowing the display to expand freely without obstruction or interference from camera modules during sliding motion.
3Measurement precision
If multiple camera modules are arranged to improve imaging performance, then the imaging capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the spatial occupation of multiple camera modules by positioning the rear camera module within the front camera module's projection area. This combining approach allows multiple camera modules to share the same spatial envelope, reducing the overall complexity of camera arrangement while maintaining enhanced imaging capabilities through multiple lenses and sensors.
