Detachable Audio-Visual Modules for Wire-Free Sound and Camera Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices suffer from poor sound quality due to built-in speakers and require wired connections for external speakers, and the fixed camera position limits photography angles.
Innovation Solution
An electronic device with detachable audio-visual devices that can be wirelessly charged and connected to a power supply device, reducing the need for wires and allowing flexible camera positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If built-in speakers are used in electronic devices, then the device structure is simple, but the sound quality is poor
Solution Approach 1:
The audio-visual system is divided into separate detachable modules (audio device and visual device) that can be independently selected and connected to the electronic device via wireless communication, allowing high-quality external audio components to be used while maintaining a simple built-in structure
Solution Approach 2:
The electronic device is designed to support multiple types of audio-visual devices through universal wireless communication protocols, enabling a single device to function with various external speakers and cameras depending on user needs
2Reliability
If external speakers are connected through wires, then the sound quality is improved, but the number of wires increases and causes clutter
Solution Approach 1:
The mechanical wire connection system is replaced with a wireless communication system that transmits audio signals and power wirelessly between the electronic device and external speakers, eliminating the need for physical cables while maintaining high-quality audio transmission
Solution Approach 2:
The power supply function and audio signal transmission are merged into a single wireless communication channel, allowing the electronic device to simultaneously charge external speakers and transmit audio signals without requiring separate wired connections
3Ease of manufacture
If the camera position is fixed on top of the electronic device, then the device structure is simple, but the photography angle is limited
Solution Approach 1:
The camera function is separated from the main electronic device body and placed in a detachable visual device that can be independently positioned and oriented, allowing flexible photography angles while keeping the main device structure simple
Solution Approach 2:
The camera position is made dynamic and adjustable through wireless connection, allowing the visual device to be moved to different locations and orientations around the electronic device to capture images from various angles as needed
4Adaptability or versatility
If audio-visual devices are detachably connected with wireless charging, then the flexibility and sound quality are improved, but the device complexity increases
Solution Approach 1:
Physical connection mechanisms and wired charging systems are replaced with wireless communication and power transmission technologies, eliminating the need for complex mechanical connectors and cable management systems while maintaining flexible detachable connections
Solution Approach 2:
A universal wireless communication interface is implemented that handles multiple functions (audio transmission, power supply, data communication) through a single standardized protocol, reducing the need for multiple specialized connection systems

AI summary
An electronic device includes: a power supply device, a first audio-visual device and a second audio-visual device. The first audio-visual device is detachably connected with the power supply device. The second audio-visual device is detachably connected with the power supply device. When the first audio-visual device is connected with the first power supply device, the power supply device charges the first audio-visual device.
