Camera Accessory Power Management via Self-Service Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face challenges in providing a convenient power supply method for accessories, as they often require complex control signals and power management systems to ensure efficient energy distribution between the camera and accessories, leading to potential inefficiencies and user inconvenience.
Innovation Solution
The implementation of an accessory and camera system that includes an information holding section to determine power requests from accessories, an accessory control section to transmit power information, and a camera control section to manage power supply based on received information, enabling efficient and convenient power management between the camera and accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera supplies power to the accessory through control signals, then the accessory can operate without its own power source, but the camera's power management system becomes more complex
Solution Approach 1:
The accessory autonomously determines its own power supply needs by checking whether it includes a battery through its own control section, and communicates this information to the camera. This self-determination mechanism eliminates the need for complex power management control in the camera, as the accessory independently makes the decision about whether it requires power from the camera.
2Use of energy by moving object
If the camera controls power supply to accessories, then power distribution can be optimized, but the control signals and communication protocol become more complex
Solution Approach 1:
The power supply decision-making function is extracted from the camera and relocated to the accessory itself. The accessory's control section independently determines whether a battery is present and whether power from the camera is needed, then communicates only the result (power request information) to the camera. This extraction simplifies the camera's control signal requirements while maintaining optimized power distribution.
3Duration of action of moving object
If the accessory always requests power from the camera, then the accessory can ensure continuous operation, but the camera's battery drains faster
Solution Approach 1:
The accessory independently assesses its own power needs by detecting whether it contains a battery. If the accessory has its own battery, it does not request power from the camera, thereby preserving camera battery life. If the accessory lacks a battery, it requests power from the camera to ensure continuous operation. This self-assessment mechanism optimizes overall system energy usage.

AI summary
An accessory is an accessary controlled by a camera. The accessory includes an information holding section that holds predetermined information by which the camera determines whether or not the accessary requests a supply of power consumed in the accessory to the camera.
