Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air handling units face issues with poor thermal and acoustic insulation due to inadequate tightness of connections between sections, leading to inefficient air treatment and compromised performance.
Innovation Solution
The air handling unit employs frameless sections with inner housing struts and multi-chamber plastic profiles to connect folded outer and inner metal sheets, ensuring a tight and secure assembly without additional means, and incorporates molded gaskets for enhanced insulation and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional connection means are used between sections, then assembly is simpler, but thermal and acoustic insulation properties deteriorate due to poor tightness
Solution Approach 1:
A foam gasket is introduced as an intermediary sealing element between adjacent insulating panels. The gasket is inserted into grooves on the panels and expands to fill gaps, creating a tight seal that prevents air leakage and improves thermal and acoustic insulation without complicating the assembly process.
Solution Approach 2:
The foam gasket is designed as a flexible sealing element that can deform to accommodate manufacturing tolerances and assembly variations. This flexibility ensures continuous sealing between panels while maintaining simple connection mechanisms.
2Object-affected harmful factors
If additional connection means are added to improve tightness, then thermal and acoustic insulation improves, but device complexity increases
Solution Approach 1:
The connection and sealing functions are merged into a single integrated system. The grooves for gasket insertion are formed as part of the insulating panel structure during manufacturing, and the same grooves serve both structural connection and sealing purposes, eliminating the need for separate sealing components.
Solution Approach 2:
The foam gasket performs self-service by automatically expanding to fill gaps and create seals upon installation. The gasket's expansion force also helps secure the connection between panels, eliminating the need for additional fastening or adjustment operations.
3Productivity
If sections are tightly interconnected to ensure proper air movement, then air handling performance improves, but manufacturing and assembly difficulty increases
Solution Approach 1:
The grooves for gasket insertion are pre-formed on the insulating panels during manufacturing. This preliminary preparation ensures that the sealing elements can be easily installed during assembly without requiring complex field operations, thus maintaining both tight connections and assembly simplicity.
