Solution Overview

Problem

Mobile terminals with cameras have a low screen-to-body ratio due to camera placement, limiting the coverage of the display screen and preventing automatic panoramic shooting.

Innovation Solution

A mobile terminal design featuring a camera mounting assembly with a sliding and rotating mechanism that allows the camera to extend from and retract into a groove, enabling both front and rear shooting modes and panoramic capabilities by rotating 180 degrees.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the camera is placed on the side of the display screen, then the camera can be positioned on the front face, but the coverage rate of the display screen decreases

Engineering Contradiction:
Improvecamera positioningVSAvoiddisplay screen coverage
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The camera is made movable through a sliding mechanism that allows it to extend from and retract into a groove on the front face. This dynamic positioning enables the camera to be placed on the front face when needed while maintaining full display screen coverage when the camera is retracted, thus resolving the contradiction between camera positioning and display screen coverage.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the camera is fixed in a certain direction, then the camera structure is simple, but automatic panoramic shooting cannot be implemented

Engineering Contradiction:
Improvecamera structureVSAvoidpanoramic shooting capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The camera is equipped with a rotating mechanism that enables it to rotate around its optical axis. This dynamic rotation capability allows the camera to capture images from multiple angles, implementing automatic panoramic shooting functionality while maintaining a relatively simple overall structure, thus resolving the contradiction between structural simplicity and panoramic shooting capability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the camera is made movable to enable panoramic shooting, then shooting versatility increases, but the mechanism complexity increases

Engineering Contradiction:
Improveshooting modesVSAvoidtransmission mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transmission mechanism is divided into two independent parts: a sliding mechanism for extending and retracting the camera along the groove, and a rotating mechanism for rotating the camera around its optical axis. This segmentation allows each mechanism to perform its specific function with simpler structure, reducing overall complexity while enabling multiple shooting modes including panoramic photography.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A single camera unit is designed to perform multiple functions through the combined sliding and rotating mechanisms. The camera can be positioned at different locations along the groove and rotated to different angles, enabling front shooting, rear shooting, and panoramic shooting modes with one camera, thus increasing versatility without requiring multiple cameras.

Inventive Principle:
Principle #6Universality (Multi-functionality)
