Lens Power Negotiation for Voltage Drop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face challenges in properly setting power supply limits for interchangeable lenses and accessories attached to imaging apparatuses, leading to potential voltage drops and improper operation due to excessive power consumption.
Innovation Solution
The implementation of a system where the lens apparatus, imaging apparatus, and accessory communicate power information to determine and transmit power modes, ensuring that the power consumption of both the lens and accessory aligns with the available power supply, with mechanisms to restrict functions when limits are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the interchangeable lens and accessory operate with high power consumption to enhance imaging functions, then the imaging capability is improved, but the voltage drops sharply when battery power is low, causing improper operation
Solution Approach 1:
The system performs preliminary power negotiation between the imaging apparatus, accessory, and interchangeable lens before operation begins. The imaging apparatus transmits power information indicating available power to the accessory, which then determines and transmits appropriate power consumption settings to the lens. This preliminary action ensures that power consumption is properly configured before imaging operations start, preventing voltage drops and ensuring stable operation while maintaining imaging capability.
2Loss of energy
If the imaging apparatus supplies limited power to ensure battery longevity, then power consumption is controlled, but the interchangeable lens and accessory cannot operate properly due to insufficient power
Solution Approach 1:
The system dynamically adjusts power consumption settings based on real-time power availability. The imaging apparatus determines its available power and transmits this power information to the accessory. The accessory then dynamically determines appropriate power consumption levels for the interchangeable lens based on the received power information, ensuring that power consumption matches available power supply while maintaining proper operation.
3Adaptability or versatility
If the accessory is designed to work with multiple types of interchangeable lenses, then adaptability is improved, but proper power setting becomes difficult due to varying power requirements of different lenses
Solution Approach 1:
The system enables self-service power configuration through automated negotiation. When an interchangeable lens is attached, the imaging apparatus automatically transmits power information to the accessory, which then automatically determines and transmits appropriate power consumption settings to the lens based on its power requirements. This eliminates the need for manual power setting and ensures proper configuration for different lens types without increasing device complexity.
