Ventilating system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting and ventilating systems often have unaesthetic appearances, inefficient designs, and lack adequate cooling of light fixtures, with many systems providing only one illumination source that fails to illuminate when quiescent.
Innovation Solution
A ventilating system with a main housing, grille, and fan configuration that allows airflow, coupled with multiple illumination devices - a first set facing downward and a second set facing upward - to provide both functional lighting modes and efficient ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting and ventilating systems combine elements of a conventional room ventilating fan with a light fixture, then ventilation and lighting functions are provided, but the apparatus has a bulky, unaesthetic appearance and a complicated design
Solution Approach 1:
The patent combines the ventilating fan and light fixture into a single integrated housing structure. The housing serves dual purposes: it encloses the fan components for ventilation while simultaneously providing mounting structure for multiple illumination devices. This merging eliminates the need for separate ventilation and lighting fixtures, reducing overall system complexity while maintaining both functions.
Solution Approach 2:
The housing structure is designed to perform multiple functions: it serves as the enclosure for the ventilating fan, provides structural support for the illumination devices, and acts as the aesthetic outer shell of the apparatus. This multi-functionality reduces the number of separate components needed, thereby simplifying the overall design while providing both ventilation and lighting capabilities.
2Adaptability or versatility
If conventional lighting and ventilating systems combine elements of a conventional room ventilating fan with a light fixture, then ventilation and lighting functions are provided, but the apparatus has a bulky, unaesthetic appearance
Solution Approach 1:
The integration of ventilation and lighting components into a single streamlined housing creates a compact, aesthetically pleasing appearance. The housing is designed with smooth contours and proportional dimensions that eliminate the bulky appearance of conventional separate fixtures, while still accommodating both fan and illumination components.
3Device complexity
If conventional lighting and ventilating systems use a single illumination source, then the design is simple, but the system fails to provide lighting when the ventilating system is quiescent and lacks certain useful functions
Solution Approach 1:
The illumination system is segmented into multiple independent illumination devices arranged in a grid formation, with each device capable of being controlled independently. This segmentation allows different lighting modes (task lighting, ambient lighting, night lighting) to be achieved by activating different combinations of devices, providing versatility while maintaining manageable system complexity.
Solution Approach 2:
The lighting system is designed to be dynamic, with illumination devices that can be selectively activated based on operational mode. When the ventilating system is quiescent, certain illumination devices can still be activated to provide ambient or night lighting, making the system adaptable to different user needs rather than being static in its functionality.
4Ease of manufacture
If conventional lighting and ventilating systems are designed with standard component arrangement, then manufacturing is straightforward, but the components are inefficiently arranged and fail to adequately cool the light fixture
Solution Approach 1:
The housing design incorporates localized features specifically oriented toward the light fixture to enhance cooling in that critical area. Airflow channels and openings are strategically positioned and shaped to direct cooling air specifically at the illumination devices, ensuring adequate heat dissipation where needed most while maintaining overall manufacturing simplicity.
