Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaners for vehicles are inefficient in supplying active ingredients to the interior, and their structural complexity increases due to the merging of air and active ingredient flow channels.
Innovation Solution
An active ingredient generation device attached to a vehicle's ceiling, featuring a body with a first air blower, an active ingredient generator, and separate flow channels for the air and active ingredient streams. The device includes blowoff ports where the active ingredient is drawn by the air stream without merging the flow channels, enhancing efficiency and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate flow channels are used for air and active ingredient streams, then supply efficiency is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional modules: a first flow channel for air stream and a second flow channel for active ingredient stream. This segmentation allows independent optimization of each flow path, improving supply efficiency while keeping each channel relatively simple in structure.
Solution Approach 2:
The second flow channel (for active ingredient) is positioned within or adjacent to the first flow channel (for air), creating a nested or integrated structure. The second blowoff port is disposed at a location where it utilizes the space and flow dynamics of the first channel without requiring completely separate external pathways.
2Device complexity
If flow channels are merged, then device complexity is reduced, but supply efficiency deteriorates
Solution Approach 1:
The device maintains separate flow channels for air and active ingredient streams, preventing mixing within the channels themselves. This segmentation ensures that each substance can be delivered efficiently to its designated blowoff port without interference from the other stream.
Solution Approach 2:
The first air stream acts as an intermediary that draws the active ingredient from the second blowoff port into the vehicle interior. The air stream serves as the transporting medium that picks up the active ingredient at the second blowoff port and delivers it to the target area, enabling efficient transfer without direct channel merging.
3Productivity
If second blowoff port is positioned to utilize air stream drawing, then active ingredient distribution is improved, but precise positioning requirements increase
Solution Approach 1:
The second blowoff port is positioned at a specific location within the body where the local flow conditions of the first air stream are optimal for drawing out the active ingredient. This local positioning leverages the existing air stream dynamics without requiring complex adjustment mechanisms.
Solution Approach 2:
The first air stream automatically performs the function of drawing the active ingredient from the second blowoff port without requiring additional active components or complex control systems. The system uses the existing air flow to serve the dual purpose of air delivery and active ingredient pickup.

Implementation Method 1
a first air blower that is disposed inside the body and generates a first air stream
Implementation Method 2
The second blowoff port is disposed at a location where the active ingredient blown out from the second blowoff port is drawn by the first air stream blown out from the first blowoff port

AI summary
An active ingredient generation device includes: a body; a first air blower that generates a first air stream; an active ingredient generator that generates an active ingredient; a first flow channel through which the first air stream generated by the first air blower flows; and a second flow channel through which the active ingredient generated by the active ingredient generator flows. The body includes: a first blowoff port from which the first air stream flowing through the first flow channel is blown out; and a second blowoff port from which the active ingredient flowing through the second flow channel is blown out. The second blowoff port is disposed at a location where the active ingredient blown out from the second blowoff port is drawn by the first air stream blown out from the first blowoff port.
