Movable Back Cover Member for Reversible Camera Stability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile phones with reversible image acquisition assemblies are prone to damaging the image acquisition assembly when shaken forcefully, as the assembly can be thrown out of its initial position, leading to collisions and inconvenience in carrying and using.

Innovation Solution

A back cover with a movable member and a first to-be-sensed member is designed, where the movable member can move between a first position exposing the image acquisition assembly and a second position covering the notch to limit the assembly's movement, preventing it from being flipped out.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the image acquisition assembly is made reversible and movable, then the functionality and adaptability of the device is improved, but the stability and reliability of the assembly deteriorates, making it prone to being thrown out during vigorous shaking

Engineering Contradiction:

Improvereversibility of image acquisition assemblyVSAvoidstability of image acquisition assembly

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies the dynamics principle by designing a movable member that can dynamically change position between a first position (exposing the image acquisition assembly) and a second position (covering the notch). This dynamic structure allows the assembly to adapt between different operational states while maintaining stability through controlled movement, resolving the contradiction between reversibility and stability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable member acts as an intermediary element between the image acquisition assembly and the back cover body. It mediates the connection by providing a controllable interface that can expose or cover the assembly, enabling reversible functionality while preventing unintended displacement during shaking through its controlled positioning mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the image acquisition assembly is exposed and movable, then the ease of operation for selfie functionality is improved, but the risk of collision and damage increases during vigorous shaking

Engineering Contradiction:

Improveselfie functionalityVSAvoidcollision risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by designing the movable member to proactively cover the notch and limit the position of the image acquisition assembly when not in use. This preventive measure counteracts the potential harmful effect of vigorous shaking before it can cause damage, while still allowing easy access when needed for selfie functionality.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The movable member is designed to perform preliminary positioning action by defaulting to a position that exposes the image acquisition assembly for ease of operation, while being capable of transitioning to a protective position. This preliminary setup ensures operational convenience while maintaining the ability to prevent collision risk when required.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a fixed structure is used for the image acquisition assembly, then the stability and reliability are improved, but the adaptability and reversibility for selfie functionality deteriorates

Engineering Contradiction:

Improvestability of image acquisition assemblyVSAvoidreversibility for selfie

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the fixed structure into a dynamic one by introducing the movable member that can shift between positions. This dynamic design maintains stability during normal use while enabling reversibility for selfie functionality, thus resolving the contradiction between fixed stability and adaptive versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by dividing the back cover into functional segments: the body, the movable member, and the image acquisition assembly. This segmentation allows the movable member to independently control the exposure of the assembly, providing both stability when covered and adaptability when exposed, thus resolving the contradiction between fixed structure and reversible functionality.

Inventive Principle:

Principle #1Segmentation

AI summary

Provided is a back cover. The back cover includes a body, a movable member, and a first to-be-sensed member. The body includes a notch. The movable member is movably disposed on the body. The first to-be-sensed member is disposed on the movable member. When the movable member is located in a first position relative to the body, a projection of the movable member onto the body is located outside the notch. When the movable member moves to a second position relative to the body, the movable member covers at least part of the notch. Further provided is an electronic assembly having the foregoing back cover. The movable member of the back cover is movable relative to the body, to be located outside the notch or cover at least part of the notch. When the back cover is applied on the electronic device, the movable member is configured to stop an image acquisition assembly of the electronic device to prevent the image acquisition assembly from being accidentally thrown out.
