Rotating Camera Module for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The demand for larger screen displays in mobile phones is hindered by the need to accommodate camera modules, limiting the screen-to-body ratio and user experience.
Innovation Solution
A mobile terminal design featuring a rotating member that allows the camera module to be recessed within the housing when not in use, enabling a larger display area by exposing it only when needed, thus optimizing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera module is permanently exposed on the front of the mobile phone, then the camera function is always accessible, but the screen-to-body ratio is reduced due to the occupied layout space
Solution Approach 1:
The camera module is mounted on a rotating member that can change its position between exposed and recessed states. The rotating member rotates about an axis defined by a curved slot, allowing the camera module to dynamically adjust its position based on operational needs, thus resolving the contradiction between accessibility and screen-to-body ratio
Solution Approach 2:
Instead of placing the camera module in a fixed two-dimensional layout on the front surface, the invention uses a rotating mechanism that adds a rotational dimension. The camera module moves along a curved path defined by the curved slot, transitioning between planes to achieve both high screen-to-body ratio and camera accessibility
2Area of stationary object
If the camera module is permanently recessed within the housing, then the screen-to-body ratio is maximized, but the camera function is not accessible when needed
Solution Approach 1:
The rotating member enables the camera module to transition from a recessed state to an exposed state through rotation. The curved slot guides the rotation path, allowing the camera module to be exposed only when needed while maintaining a recessed position during normal use, thus maximizing screen-to-body ratio while preserving accessibility
3Device complexity
If a traditional fixed layout is used for the camera module, then the structure is simple, but the screen-to-body ratio cannot be increased
Solution Approach 1:
The invention introduces a rotating member with a curved slot mechanism that allows the camera module to move between exposed and recessed positions. This dynamic structure replaces the traditional fixed layout, enabling increased screen-to-body ratio while maintaining reasonable structural complexity through the use of a single rotation axis and engaging structures
Solution Approach 2:
The rotating member is rotatably coupled to the housing and can be received within the housing when in the recessed position. The engaging structures (curved slot and slider) are nested within each other, allowing the camera module to be hidden within the housing boundaries while maintaining the capability to rotate outward when needed
