Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable lighting installations are not effectively configured to use LED light sources for high illumination due to lack of guaranteed cooling solutions, leading to operational challenges and safety issues with massive heatsinks.
Innovation Solution
An inflatable lighting installation with a liquid cooling system that includes a heatsink, hydraulic pump, and expansion tank, where the cooling system is integrated inside or outside the base, using flexible pipes to manage heat dissipation without increasing the weight or size of the upper part, allowing for efficient cooling of LED light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a massive heatsink is used to cool LED light sources, then cooling effectiveness is improved, but weight and size of the installation increase
Solution Approach 1:
The patent applies hydraulic cooling by circulating water through channels formed in the base structure. The base contains internal water channels that serve as heat exchange paths, allowing coolant to flow through and absorb heat from LED light sources positioned above the base. This hydraulic cooling system replaces traditional massive heatsinks with a fluid-based thermal management approach that leverages the base structure itself as the cooling mechanism.
2Illumination intensity
If LED light sources with high power are used to achieve high illumination levels, then luminous flux is improved, but heat generation increases requiring larger cooling systems
Solution Approach 1:
The base structure serves multiple functions simultaneously: it provides mechanical support for the LED light sources, contains internal water channels for hydraulic cooling, and acts as the cooling medium circulation system. This multi-functional design allows high-power LED light sources to be installed without requiring separate massive heatsinks, as the base itself performs both structural and thermal management roles.
3Reliability
If conventional cooling systems are used with inflatable lighting installations, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the structural base with the cooling system by forming water channels directly within the base structure. This integration eliminates the need for separate cooling components, pipes, and mounting hardware that would otherwise be required. The base structure and cooling system become a unified component, reducing overall system complexity while maintaining reliable hydraulic cooling for high-power LED light sources.
