Solution Overview
Problem
Existing lighting devices, such as strobe devices, face challenges in maintaining usability and effectively managing heat generation due to variations in battery performance, leading to reduced light emission capabilities and impaired functionality, especially when identification information is unavailable or battery aging occurs.
Innovation Solution
A lighting device equipped with a processor and memory that acquires battery information, including temperature, to determine parameters for controlling light emission, allowing for adaptive management of heat protection without compromising usability across different battery types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light emission is limited based on a battery that generates more heat, then product protection is improved, but the number of light emission times and light emission performance are reduced
Solution Approach 1:
The lighting device dynamically adjusts light emission control parameters based on real-time battery temperature acquisition. The control unit modifies emission limits adaptively according to actual thermal conditions rather than using fixed conservative limits, allowing optimization between protection and productivity as battery conditions change during operation.
Solution Approach 2:
The system changes operational parameters (light emission limits) based on battery temperature measurements. By monitoring battery temperature and adjusting emission parameters accordingly, the system transitions from static conservative limits to dynamic parameter adjustment, resolving the contradiction between protection and performance.
2Reliability
If charging is limited from an initial state when identification information is unavailable, then battery protection is improved, but usability in photographing sites is reduced
Solution Approach 1:
The system performs preliminary battery temperature acquisition and evaluation before initiating full charging or light emission operations. By acquiring temperature information in advance and evaluating battery state beforehand, the system can make informed decisions about operational limits, improving usability while maintaining protection through preliminary assessment rather than restrictive default limits.
3Device complexity
If a fixed charging mode is selected, then control simplicity is improved, but adaptability to battery aging and different battery types is reduced
Solution Approach 1:
The system implements feedback control by continuously acquiring battery temperature information and using this data to adjust light emission parameters. The control unit receives feedback from temperature sensors and modifies operational parameters accordingly, enabling the system to adapt to different battery types and aging conditions while maintaining relatively simple control architecture through automated feedback loops.
