Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation and illumination systems require separate installations, leading to increased space requirements, complex wiring, and reduced efficiency due to the need for optimal positioning of optical pipes and ducts, which complicates installation and design.
Innovation Solution
A combined illumination and ventilation duct featuring optical pipes with a total reflection layer and a flexible connector that allows for simultaneous air and light flow, with a connector that can be easily joined and secured to the ceiling, reducing installation space and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate ventilation duct and illumination optical pipe are installed, then each can be positioned optimally for its function, but installation space increases and wiring becomes complicated
Solution Approach 1:
The patent combines the ventilation duct and illumination optical pipe into a single integrated structure where the optical pipe is positioned inside the duct. This merging eliminates separate installations, reduces wiring complexity, and simplifies ceiling penetration requirements while maintaining both ventilation and illumination functions through the unified structure.
Solution Approach 2:
The integrated duct structure serves multiple functions simultaneously: it provides ventilation air passage and houses the optical pipe for illumination. This multi-functionality allows a single installation to fulfill both ventilation and lighting requirements, reducing overall system complexity and installation burden.
2Reliability
If separate ventilation duct and illumination optical pipe are installed, then each can operate independently, but occupied space on ceiling increases
Solution Approach 1:
The optical pipe is nested inside the ventilation duct, with the smaller illumination component positioned within the larger ventilation structure. This nesting arrangement allows both systems to occupy the same ceiling space simultaneously, reducing the total occupied area while maintaining operational independence of each function.
3Productivity
If optical pipe and duct are arranged on optimal positions, then illumination and ventilation efficiency are maximized, but installation becomes more complicated
Solution Approach 1:
By merging the duct and optical pipe into a single integrated component, the invention eliminates the need for separate positioning and alignment operations. The unified structure is installed as one unit, significantly simplifying the installation process while maintaining the efficiency benefits of optimized positioning for both ventilation and illumination functions.

Data Source
AI summary
A combined illumination and ventilation duct is disclosed. The present invention includes at least two optical pipes having air flown inside wherein light proceeds within the at least two optical pipes by being totally reflected and a connector connecting the at least two optical pipes together, the connector having a connecting nipple to be connected to a pipe. An upper part of the duct is embedded in a fake ceiling under a real ceiling and a lower part is exposed under the fake ceiling. Alternatively, the whole combined illumination and ventilation duct is installed to be exposed under the fake ceiling. As air and light pass through the combined illumination and ventilation duct, the light is totally reflected within the optical pipes to illuminate an indoor space and the air is supplied or discharged to ventilate the indoor space.
