Handheld Bluetooth Photography Screen for Rear-Camera Selfies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphones with rear cameras have good photographing capabilities but lack a visible screen, making it difficult to take clear selfies, especially when users cannot see the lens, and selfie sticks have limitations in capturing full-body photos with multiple people.
Innovation Solution
A handheld Bluetooth photographing screen with a display screen, control circuit board, Bluetooth and WiFi modules, and control buttons that allow communication and control of an external mobile terminal for photography and display functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a rear camera with high pixels is used for photographing, then the photographing quality is improved, but the user cannot see the lens and take photos
Solution Approach 1:
The patent introduces a separate display screen as an intermediary device that receives video signals from the rear camera via Bluetooth or WiFi connection. This allows the user to view the rear camera feed on an external screen, solving the visibility problem while maintaining the use of the high-quality rear camera for photographing.
2Length of moving object
If a selfie stick is used to extend the distance for group photos, then the photographing distance is improved, but the length is limited within 2 meters and cannot capture full body photos of many people
Solution Approach 1:
The patent transitions from a mechanical extension solution (selfie stick) to a wireless communication solution. By using Bluetooth and WiFi modules, the display screen can be positioned anywhere within wireless range, effectively extending the photographing distance beyond physical stick limitations and enabling full-body group photos.
3Measurement precision
If a front camera with high pixels and selfie stick are used together, then the photographing quality and distance are improved, but the cost of the mobile phone becomes high
Solution Approach 1:
The patent extracts the display function from the mobile phone itself and implements it on a separate display screen device. This allows the mobile phone to focus on its core photographing function using the rear camera, while the display capabilities are provided by the external screen, avoiding the need to upgrade the phone's front camera and reducing overall cost.
4Ease of operation
If delayed shooting function is used for taking photos, then the user can take photos without someone nearby, but the user cannot see the lens and it is difficult to take photos that satisfy the user
Solution Approach 1:
The patent implements real-time video feedback by transmitting the rear camera feed to the display screen. The user can see what the camera is capturing in real-time and adjust their position or pose accordingly, ensuring photographing quality while maintaining independence through wireless connection.

AI summary
A handheld Bluetooth photographing screen includes a main body. The main body is equipped with a display screen and a control circuit board electrically connected to the display screen. The handheld Bluetooth photographing screen further includes a Bluetooth module and a WiFi module both electrically connected to the control circuit board. Therefore, the handheld Bluetooth photographing screen can communicate with a terminal device such as a mobile phone through the Bluetooth module. The Bluetooth module, after receiving the photography control signal from the control circuit board, transmits the photography control signal to the mobile phone and controls a photography function of the mobile phone to achieve a purpose of photography. The WiFi module receives a display signal from the mobile phone and transmits the display signal to the control circuit board, and then the display screen can achieve simultaneous display with the mobile phone, achieving real-time viewing of photography effects.
