Remote Electrode Air Ionization System for Transit Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior air ionization systems for transit vehicles are cumbersome to install due to the positioning challenges of the block with attached electrodes within the air stream, requiring a more efficient and user-friendly installation method.
Innovation Solution
The air ionization system features remotely mounted air ionizing electrodes connected to electronic control circuitry housed in a block, with the electrodes positioned directly within the air stream using a bracket or integrated into the air distribution unit's housing, allowing for easier installation and alignment perpendicular to airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the block with attached electrodes is positioned within the air stream, then proper electrode placement is achieved, but installation becomes cumbersome and difficult
Solution Approach 1:
The system is divided into separate components: the block containing electronic control circuitry is separated from the air ionizing electrodes. The electrodes are mounted remotely on a bracket or integrated into the air distribution unit housing, while the block is positioned separately. This segmentation allows independent positioning and installation of each component, solving the contradiction between precise electrode placement and ease of installation.
2Ease of operation
If the electrodes are remotely mounted from the block, then installation ease is improved, but electrode positioning within the air stream becomes challenging
Solution Approach 1:
A bracket serves as an intermediary structure to mount the air ionizing electrodes at the proper location within the air stream. The bracket can be attached to the air distribution unit housing or integrated into it, providing precise positioning for the electrodes while allowing the block to be installed separately. This intermediary structure resolves the positioning challenge created by remote mounting.
