Ventilating system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting and ventilating systems often have a bulky appearance, inefficient design, 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 ventilating system with a main housing, fan, grille, and illumination devices, including a plate and lens, that allows for airflow and provides independent illumination modes through multiple light sources, including a grid formation and a second illumination device facing upwardly to illuminate the grille, enabling adjustable lighting intensities and automatic operation.
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 the system provides both ventilation and lighting functions, but the system has a bulky and unaesthetic appearance
Solution Approach 1:
The patent combines the ventilating fan and light fixture into a single integrated unit, merging two separate functions into one compact device. The housing contains both the fan assembly and illumination devices, eliminating the need for separate ventilation and lighting fixtures.
Solution Approach 2:
The ventilating system is designed to perform multiple functions simultaneously - it provides both air circulation through the fan and illumination through the light fixture. The system can operate in different modes (ventilation only, lighting only, or both together), making it a universal device for room environmental control.
2Adaptability or versatility
If conventional lighting and ventilating systems employ a complicated design, then the system provides multiple functions, but the components are inefficiently arranged
Solution Approach 1:
The housing is divided into distinct sections - a front housing portion containing the fan and a rear housing portion containing the light fixture and control components. This segmentation allows each component to be optimally positioned and accessed independently, simplifying the overall design and improving component arrangement efficiency.
Solution Approach 2:
The patent utilizes three-dimensional space efficiently by arranging components in different spatial zones within the housing. The fan is positioned in the front section while the light fixture occupies the rear section, creating an optimized spatial layout that reduces complexity and improves airflow and light distribution.
3Temperature
If conventional lighting and ventilating systems fail to adequately cool the light fixture, then the system provides basic ventilation, but the light fixture overheats
Solution Approach 1:
The ventilation system is designed with localized airflow paths that specifically target the light fixture area for cooling. The fan creates air circulation that directs cool air toward the light fixture and facilitates heat dissipation from the illumination devices, providing targeted thermal management where needed.
Solution Approach 2:
The housing structure acts as an intermediary thermal management system, with strategically positioned air intake and exhaust openings that facilitate heat transfer from the light fixture to the surrounding environment. The design incorporates thermal pathways that efficiently conduct heat away from the light fixture without compromising overall ventilation performance.
4Adaptability or versatility
If conventional lighting and ventilating systems include only one illumination source, then the system design is simplified, but the system lacks certain useful functions including failure to provide lighting when the ventilating system is quiescent
Solution Approach 1:
The system incorporates multiple illumination devices that can be independently controlled and activated based on operational requirements. The control system allows dynamic selection of lighting modes - the light fixture can illuminate independently when the fan is not operating, providing versatility in different usage scenarios without requiring complex mechanical switches.
Solution Approach 2:
The control system provides feedback-based operation where the state of the fan and light fixture are monitored and used to automatically control illumination. The system can detect when ventilation is quiescent and automatically activate the light fixture, or coordinate lighting with fan operation, eliminating the need for manual control and simplifying user interaction.
