Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor spaces face challenges in maintaining air quality and air movement while providing adequate lighting, as existing HVAC systems are insufficient for supplementing air circulation and LED lighting systems often suffer from improper thermal management, leading to reduced performance and lifespan due to heat buildup.
Innovation Solution
A combination fan and LED light system configured within a housing that fits into a standard ceiling tile, utilizing a small flow fan for convective heat transfer and an air diversion mechanism to distribute air evenly, along with a vented mechanical equipment casing to direct airflow over mechanical components, enhancing cooling and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lights are used for illumination, then lighting efficiency is improved, but heat buildup occurs that reduces lifespan and performance
Solution Approach 1:
The patent utilizes the heat generated by LED lights and mechanical equipment as a driver for natural convection currents. By designing the housing with strategic intake and outlet openings, the system converts the harmful heat buildup into a beneficial cooling mechanism where hot air rises and exits through upper openings, drawing in cooler air through lower openings to continuously cool the components.
Solution Approach 2:
The cooling system operates autonomously without external power or control mechanisms. The housing structure itself, with its integrated air intake and outlet openings positioned at different heights, enables self-cooling through natural convection. The system serves its own thermal management needs through its inherent design rather than requiring separate cooling equipment.
2Device complexity
If a single HVAC system is used for all rooms, then system complexity is reduced, but air quality and air movement in individual spaces deteriorates
Solution Approach 1:
The patent divides the air circulation function into two levels: a central HVAC system that provides bulk air distribution, and individual ceiling-mounted units that segment and optimize air movement within specific rooms or zones. Each unit independently manages local air quality and circulation, supplementing the centralized system without requiring complete system replacement.
Solution Approach 2:
The ceiling-mounted unit performs multiple functions within a single device: it provides supplemental air circulation, cools LED lighting fixtures, cools mechanical equipment, and improves local air quality. This multi-functional approach allows one system to address various environmental control needs without requiring separate specialized systems for each function.
3Adaptability or versatility
If LED lights and fan are installed separately, then installation flexibility is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines LED light fixtures, fan assemblies, and mechanical equipment into a single integrated ceiling-mounted unit. This consolidation maintains installation flexibility by providing a self-contained module that can be installed in standard ceiling locations, while reducing overall system complexity by eliminating the need to coordinate separate installations of lighting, ventilation, and equipment housing.
