Solution Overview

Problem

Mobile terminals face a challenge in increasing their screen-to-body ratio while maintaining a diverse shooting scenario for cameras, as traditional telescopic camera arrangements are limited in versatility.

Innovation Solution

A transmission mechanism with a driving mechanism, a transmission assembly, and a mounting seat that allows the camera module to move between different positions, enabling it to function as both front and rear cameras, thereby increasing the screen-to-body ratio and allowing for shooting at multiple angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a telescopic camera is arranged in a mobile terminal to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the shooting scenario diversity deteriorates

Engineering Contradiction:
Improvescreen-to-body ratioVSAvoidshooting scenario diversity
Core Design Contradiction:
Area of moving objectVSAdaptability or versatility

Solution Approach 1:

The camera module is designed to be movable between different positions (first position for rear camera, second position for front camera) rather than being fixed, allowing the system to dynamically adapt to different shooting scenarios while maintaining a high screen-to-body ratio

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A single camera module performs multiple functions by moving to different positions: it acts as a rear camera at the first position and a front camera at the second position, eliminating the need for separate camera modules for different functions

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

2Adaptability or versatility

If a camera module is made movable to enable multiple shooting scenarios, then the shooting versatility is improved, but the device complexity increases

Engineering Contradiction:
Improveshooting scenario diversityVSAvoidtransmission mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The driving mechanism, transmission assembly, and mounting seat are combined into an integrated transmission mechanism that controls the camera module's movement, reducing the need for separate components and simplifying the overall structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The camera module is nested within the transmission mechanism, which itself is integrated into the mobile terminal structure, allowing compact arrangement of moving parts without increasing overall device footprint

Inventive Principle:
Principle #7Nested doll (Nesting)
