Reversible Power Port Switching for Camera Peripheral Power Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powering peripheral equipment for surveillance cameras in harsh environments, such as campuses where long-distance AC power routing is not allowed, is challenging due to increased costs and reduced reliability from additional power transmission lines and adapters.
Innovation Solution
A reversible powering device with a power input determining module and a switch controlling module that allows power input from one port to be output from another, enabling power sharing between electronic equipment with at least two power input ports, eliminating the need for separate transmission lines and adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external power units and adapters are used to power peripheral equipment, then the equipment can be powered reliably, but the cost and system complexity increase
Solution Approach 1:
The patent merges the camera's power input port with the pickup's power input port through a switching circuit, allowing the camera to function as a power source for the pickup. This combines two separate power supply paths into one shared system, reducing the need for external power units and adapters while maintaining reliable power delivery to both devices.
Solution Approach 2:
The camera's power input port is designed to serve dual functions: receiving power when the camera is the powered device, and outputting power when the camera acts as the power source for peripheral equipment. This multi-functionality eliminates the need for separate power transmission lines and adapters, reducing system complexity while ensuring reliable powering.
2Ease of operation
If additional power transmission lines and adapters are installed, then peripheral equipment can be powered, but the cost increases
Solution Approach 1:
The patent combines the power transmission function into the existing data communication cable infrastructure, eliminating the need for separate power transmission lines and adapters. The switching circuit enables bidirectional power flow through the same cable used for data communication, significantly reducing installation costs while maintaining full powering capability for peripheral equipment.
Solution Approach 2:
The power input ports are designed to universally handle both power reception and power transmission functions. The same physical port and cable infrastructure serve dual purposes depending on the operational mode, eliminating the need for additional hardware components and reducing overall system cost while preserving complete powering capability.
3Ease of operation
If separate power transmission lines and adapters are used, then peripheral equipment can be powered, but the system reliability reduces
Solution Approach 1:
The patent merges the power supply path into a unified system where the camera and pickup share a common power interface through a switching circuit. This eliminates multiple connection points and external adapters that could fail, reducing the number of potential failure points while maintaining the ability to power peripheral equipment reliably through intelligent power direction control.
