Interchangeable HVAC Panel Assembly to Reduce Manufacturing Costs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems require separate manufacturing and assembly of single wall and double walled access panels, increasing costs due to the need for different components for varying applications, such as cleaning and contaminant protection.
Innovation Solution
An adjustable panel designed as a single component with a base panel, flange, and interchangeable stiffener and liner panels, allowing conversion between single wall and double walled configurations through a system of openings and fasteners, reducing the need for multiple manufactured parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate single wall and double walled access panels are manufactured for different applications, then specific functional requirements (cleaning, contaminant protection) are met, but manufacturing costs and assembly complexity increase
Solution Approach 1:
The access panel is designed with a universal base panel that can accommodate both single wall and double walled configurations through interchangeable brackets, allowing one base component to serve multiple functional requirements
Solution Approach 2:
The panel system is divided into a permanent base panel and interchangeable brackets (single wall bracket and double walled bracket) that can be separately manufactured and assembled, allowing flexibility in configuration while simplifying manufacturing of individual components
2Reliability
If separate single wall and double walled access panels are manufactured, then specific application requirements are satisfied, but production expenses increase
Solution Approach 1:
A single base panel design serves both single wall and double walled applications, reducing the number of unique parts that need to be manufactured and stocked, thereby lowering production expenses while maintaining application-specific performance
Solution Approach 2:
The interchangeable brackets can be removed and replaced between configurations, allowing the same base panel to be reused for different applications without waste, reducing overall material consumption and manufacturing costs

AI summary
A panel assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a base panel having a sheet and a flange formed around a perimeter of the sheet, where the flange includes a plurality of openings, a stiffener bracket configured to couple to the flange and reinforce the base panel, and a liner panel configured to couple to the flange and reinforce the base panel, where the plurality of openings is configured to interchangeably couple to the stiffener bracket and the liner panel.
