Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydroxyl generators for air purification are difficult to maintain, especially in tight spaces, due to limited access and complex component arrangements, which increases repair time and requires specialized skills.
Innovation Solution
A modular hydroxyl generator housing design with separate interior regions for hydroxyl generation and electrical components, featuring slidable ballast shelves and optics racks, allowing for easy access and replacement of components through a single cabinet door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components are arranged in a compact configuration to reduce device size, then space utilization is improved, but access for maintenance becomes more difficult
Solution Approach 1:
The housing is divided into separate interior regions (first interior region for hydroxyl generation, second interior region for electrical components) that can be accessed independently. The slidable ballast shelf and optics racks can be removed separately from the housing, allowing maintenance personnel to access and replace components without disassembling the entire device.
2Device complexity
If multiple components are integrated into a single housing, then device complexity is reduced, but maintenance time increases
Solution Approach 1:
The housing is segmented into functionally independent regions with separate access points. The first interior region contains hydroxyl generation components while the second interior region contains electrical components like ballast and PLCs. This segmentation allows technicians to replace specific components (e.g., UV lamps, ballast, PLCs) without affecting other parts of the system, significantly reducing maintenance time.
Solution Approach 2:
The ballast shelf is designed to be slidable rather than fixed, allowing dynamic reconfiguration of the interior region. This enables easy access to electrical components during maintenance while maintaining a compact integrated structure during operation.
3Volume of moving object
If components are placed in hard-to-reach locations to optimize space, then space utilization is improved, but skill requirements for maintenance increase
Solution Approach 1:
The housing is divided into accessible regions with the second interior region specifically designed for electrical components. The slidable ballast shelf can be easily pulled out through the housing opening, bringing components like ballast and PLCs within easy reach of maintenance personnel, thereby reducing skill requirements while maintaining compact space utilization.

AI summary
A hydroxyl generator housing designed for maintainability to allow safe, quick, and easy replacement of hydroxyl generator component parts. This design minimizes repair time in the field for corrective and preventative maintenance, including replacing UV optic lamps, ballast, Programmable Logic Controllers (PLCs), and other electrical components. The housing is formed to include two separate interior regions. The first interior region is for hydroxyl generation/treatment. The second interior region is for a slidable ballast shelf design. The housing design also includes ultraviolet (UV) lamps placed into insertable optics racks. All the hydroxyl generator component parts are accessible through a single cabinet door. Entire component parts can be swapped out in the field, including slidable optics racks holding UV optic lamps, slidable ballast shelves with ballast, PLCs, current sensors, cabling, and other electrical components. The component parts can be returned back to the factory for corrective and preventative maintenance.
