Mobile Terminal Ejection Assembly for Flush Camera Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone designs face challenges in maximizing screen ratio without compromising the appearance by avoiding holes in the housing, as methods like independent pop-up cameras or bone conduction technology either affect aesthetics or result in poor sound quality.
Innovation Solution
An ejection assembly with a driving mechanism, decorative members, and lifting mechanisms that allow the camera module to retract flush with the screen assembly and back cover, eliminating visible steps and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an independent pop-up camera is used to maximize screen ratio, then the screen ratio is improved, but a hole must be defined in the housing and the camera protrudes out, affecting the overall appearance
Solution Approach 1:
The camera module is designed to be dynamically movable between a retracted state (flush with housing) and an extended state (protruding for photography). This dynamic mechanism allows the device to maintain a clean appearance when the camera is not in use while still providing full functionality when needed, resolving the contradiction between maximizing screen ratio and maintaining appearance.
2Shape
If bone conduction technology is used to avoid holes in housing, then the appearance is improved, but the sound quality becomes poor
Solution Approach 1:
The invention extracts the camera module from a fixed position and places it on a movable platform, allowing it to be taken out (extended) only when needed for photography. This extraction approach enables the camera to be hidden within the housing during normal use, maintaining appearance, while still being accessible when required, avoiding the need for bone conduction technology that compromises sound quality.
3Ease of operation
If the camera module is extended out of the housing, then photography function is improved, but visible steps are created affecting appearance
Solution Approach 1:
The camera module is designed to be dynamically movable between a retracted state (flush with housing) and an extended state (protruding for photography). This dynamic mechanism allows the device to maintain a clean appearance when the camera is not in use while still providing full functionality when needed, resolving the contradiction between maximizing screen ratio and maintaining appearance.
Solution Approach 2:
The camera module is moved along the vertical dimension (thickness direction) of the device rather than creating horizontal steps on the surface. By extending upward from the housing in the thickness direction, the camera maintains a flush appearance with the housing surfaces while still providing protrusion functionality, eliminating visible steps that would affect appearance.
