Ventilating Grille With Nested LED Lighting for Independent Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting and ventilating systems often have a bulky, unaesthetic design, inefficient component arrangement, inadequate cooling of light fixtures, and lack functionality such as providing lighting when the ventilating system is quiescent, with many systems relying on a single illumination source.
Innovation Solution
A lighting and ventilating system with a main housing that includes a fan wheel for air flow, a grille with apertures for air intake, and a set of illumination devices that can be configured to emit dynamic illumination, allowing for independent ventilation and lighting, with multiple illumination sources and adjustable brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting and ventilating systems combine a ventilating fan with a light fixture, then ventilation and lighting functions are integrated, but the appearance becomes bulky and unaesthetic
Solution Approach 1:
The illumination devices are nested within recesses formed in the housing structure. The housing includes recesses that receive and accommodate the illumination devices, allowing them to be integrated into the overall housing design rather than adding external bulk. This nesting approach maintains a sleek appearance while providing both ventilation and lighting functions.
2Device complexity
If conventional systems use a single illumination source, then the design is simple, but the system fails to provide lighting when the ventilating system is quiescent
Solution Approach 1:
The housing is designed with multiple recesses that can accommodate multiple illumination devices, allowing the system to provide lighting independently of ventilation operation. The control system enables the illumination devices to operate in various modes including when the ventilating fan is not running, making the lighting function universal and independent rather than contingent on ventilation activity.
3Ease of manufacture
If illumination devices are mounted on the exterior of the housing, then installation is simple, but the design becomes unaesthetic and space-consuming
Solution Approach 1:
The housing includes integrally formed recesses that receive the illumination devices, nesting them within the housing structure rather than mounting them on the exterior. This approach maintains aesthetic appearance by incorporating the lights into the housing design while still allowing relatively simple installation through the recess structures.
4Device complexity
If the housing structure does not include integrated cooling, then the design is simpler, but the light fixture becomes inadequately cooled
Solution Approach 1:
The ventilation system and illumination device cooling are merged into a single integrated approach. The housing structure includes features that channel air flow from the ventilating fan to cool the illumination devices. The recesses and housing design work together to provide both structural support and thermal management, combining ventilation and cooling functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides efficient ventilation and adjustable lighting, ensuring illumination is maintained even when the ventilating system is not in use, with a more aesthetically pleasing and functionally enhanced design compared to conventional systems.
Implementation Method 1
A fan wheel can be supported in the main housing and it can be operable to generate a flow of air
Implementation Method 2
a set of illumination devices can be configured and arranged to emit a dynamic illumination event
