Solution Overview
Problem
Conventional video doorbell systems face challenges in providing sufficient energy to both the camera and doorbell components, limiting their functionality and compatibility with various doorbell designs.
Innovation Solution
A video doorbell system with a mode switching controller that allows remote switching between modes to bypass either the ringtone generating unit or the video generating module, enabling charging from an external power source and ensuring continuous operation of the image capturing function without constraining the doorbell's original functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the doorbell is short-circuited to provide full energy to the camera, then the camera can acquire sufficient energy for complete operation, but the doorbell function is lost and alternative of doorbell and camera does not conform to consumer demand
Solution Approach 1:
The system dynamically switches between two operational modes: in the first mode, the power supply connects to both the doorbell and camera simultaneously for normal operation; in the second mode, the power supply connects only to the camera for charging. This dynamic switching resolves the contradiction by allowing the system to adapt its power distribution based on operational needs, preserving both doorbell functionality and camera energy requirements.
Solution Approach 2:
The invention changes the parameter of power supply connection state by introducing a mode switching controller that can alter the electrical circuit configuration. By switching between connected and disconnected states of the power supply relative to the doorbell and camera, the system achieves flexible energy management that satisfies both contradictory requirements.
2Duration of action of stationary object
If the video generating module is always connected to the power supply, then the camera can continuously operate, but the doorbell cannot function properly due to power constraints
Solution Approach 1:
The power supply system is segmented into two independent power delivery paths controlled by the mode switching controller. One path supplies power to the doorbell, and the other supplies power to the camera. This segmentation allows each component to receive adequate power independently, resolving the contradiction between continuous camera operation and reliable doorbell function.
Solution Approach 2:
The mode switching controller acts as an intermediary device that mediates between the power supply and the two loads (doorbell and camera). It intelligently routes power to the appropriate component based on the current operational mode, ensuring both the doorbell and camera receive sufficient power for their respective functions without interference.
3Device complexity
If the system uses a fixed power distribution architecture, then the circuit design is simple, but the system cannot adapt to different doorbell designs and consumer demands
Solution Approach 1:
The mode switching controller provides multi-functionality by enabling the power supply system to serve two different operational modes: normal dual-component operation and camera-only charging operation. This universal design allows the same circuit architecture to accommodate various doorbell types and consumer requirements, enhancing adaptability without requiring completely different circuit designs for each application scenario.

Data Source
AI summary
A video doorbell system coupled with a ringtone generating unit is applied by a power supply adjusting method and includes a video generating module and a mode switching controller. The video generating module includes a power storing component. The mode switching controller can be switched into a first mode or a second mode in a remote controlling manner. While the mode switching controller is switched into the first mode, the ringtone generating unit is bypassed and an external power source is connected to the video generating module, so as to charge the power storing component by the external power source. While the mode switching controller is switched into the second mode, the video generating module is bypassed and the external power source is connected to the ringtone generating unit, and the video generating module can execute image capturing function via the power storing component.
