Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating devices for lamps with emergency power supplies face challenges in managing thermal stress, as both electronic components and batteries are sensitive to temperature extremes, leading to performance degradation and requiring separate, complex installations.
Innovation Solution
Combining electronic components and emergency power supply means within a single housing with a thermal barrier, utilizing a thermally separated design where intermediate walls and air circulation paths prevent excessive heat transfer between the two areas, and using printed circuit boards for electrical connections to maintain thermal separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic components and emergency power supply are combined in a single housing, then device complexity and installation effort are reduced, but thermal stress on the emergency power supply increases due to heat from electronic components
Solution Approach 1:
The housing is divided into a first area for electronic components and a second area for the emergency power supply, creating spatial separation that reduces thermal interaction while maintaining a unified device structure
Solution Approach 2:
A printed circuit board is used as an intermediary element that provides electrical connection between the first and second areas while maintaining thermal separation, as the PCB extends from the first area into the second area without creating significant thermal coupling
2Area of stationary object
If electronic components are positioned close to the emergency power supply to save space, then the device footprint is reduced, but the performance of the battery deteriorates due to temperature sensitivity
Solution Approach 1:
The housing interior is segmented into thermally isolated zones using intermediate walls, allowing compact overall dimensions while maintaining adequate thermal separation to protect battery performance
Solution Approach 2:
Different regions of the housing are assigned different thermal characteristics, with the second area designed to maintain stable temperature for the temperature-sensitive emergency power supply while the first area allows higher temperatures for electronic components
