Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During remote calls or meetings, users must manually adjust the position and orientation of a mobile communication device to maintain a good audio effect and ensure the camera captures the speaker, which is inconvenient and disruptive.
Innovation Solution
A dock equipped with an audio-receiving circuit, a rotating module, and a controller circuit that automatically orients the mobile communication device towards the audio source by analyzing audio signals and adjusting its position to maintain optimal audio and video capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually adjust the mobile communication device to maintain good audio effect and capture the speaker, then the audio and video quality are improved, but the ease of operation deteriorates due to continuous manual adjustments required
Solution Approach 1:
The dock system performs automatic audio source tracking and device orientation without requiring user intervention. The audio-receiving circuit continuously monitors audio directions, the controller circuit processes this information to determine the audio source location, and the rotating module automatically adjusts the mobile device's orientation, enabling the system to serve itself rather than requiring manual user adjustment
Solution Approach 2:
The patent replaces the mechanical manual adjustment system with an automated electronic control system. Instead of users physically moving the device, the rotating module uses motor-driven rotation controlled by the controller circuit to achieve the same orientation adjustment, substituting mechanical user action with an automated electromechanical system
2Reliability
If the mobile communication device is manually repositioned to track the speaker, then the audio capture is improved, but the device complexity increases due to the need for continuous manual control
Solution Approach 1:
The dock system automatically tracks the audio source and adjusts the mobile device without requiring user control. The audio-receiving circuit continuously monitors sound directions, the controller circuit processes this data to determine speaker location, and the rotating module executes automatic repositioning, eliminating the need for manual control while maintaining reliable audio capture
Solution Approach 2:
The system performs preliminary audio direction detection and processing continuously before any repositioning is needed. The audio-receiving circuit and controller circuit are constantly analyzing audio signals to predict and prepare for the next optimal positioning, so when adjustment is needed, the system already has the information required to execute the repositioning efficiently

AI summary
A dock and an operation method therefor are provided. The dock is suitable for propping up a mobile communication device. The dock includes an audio-receiving circuit, a rotating module, a communication circuit, and a controller circuit. The controller circuit is coupled to the audio-receiving circuit, the rotating module, and the communication circuit. The controller circuit transmits at least one of a plurality of audio signals generated by the audio-receiving circuit to the mobile communication device through the communication circuit, and determines an audio direction of an audio source according to the plurality of audio signals. The controller circuit controls the rotating module to rotate according to the audio direction, so as to bring the mobile communication device face toward the audio source.
