Panel for an air handling unit, method for assembling such a panel, and air handling unit including such a panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air handling units face high production costs and handling difficulties due to heavy panels with metal joining elements, and reduced panel sizes lead to increased numbers and air leaks.
Innovation Solution
Large dimension panels assembled from lightweight components with internal and peripheral joining elements, eliminating the need for a structural framework, reducing air leaks, and simplifying handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If metal joining elements are used around each panel, then panels can be assembled and aligned, but production costs increase and assembly time increases
Solution Approach 1:
The panel is divided into two types (first panel with male connector, second panel with female connector) that can be assembled in different configurations. This segmentation allows flexible assembly options while using standardized components, reducing overall complexity.
Solution Approach 2:
The joining elements are designed to serve multiple functions: alignment of panels, structural connection, and enabling different panel configurations (first and second types). This multi-functionality reduces the need for specialized components for each function.
2Weight of moving object
If panel size is reduced to limit weight, then handling becomes easier, but the number of panels increases and air leaks occur between panels
Solution Approach 1:
The joining elements are pre-designed with integrated sealing features that prevent air leaks before assembly is complete. The male and female connectors include sealing surfaces that automatically engage to maintain air tightness when panels are joined.
3Reliability
If panel size is increased to cover surfaces completely, then number of panels decreases and air leaks are reduced, but handling becomes difficult and dangerous
Solution Approach 1:
Large panel surfaces are divided into multiple smaller panel units that can be easily handled and assembled. The panels are connected through joining elements that create a unified structure, maintaining air tightness while improving handling safety.
4Strength
If heavy panels with metal joining elements are used, then structural rigidity is ensured, but production costs increase and handling becomes difficult
Solution Approach 1:
The panel structure combines different materials (metal joining elements with panel materials) to achieve optimal strength-to-weight ratio and cost efficiency. The joining elements provide necessary rigidity while the panel materials can be selected for cost-effectiveness.

AI summary
This panel (6) for an air handling unit defines a main axis (X6) perpendicular to its surface and includes at least two first plates (8), each provided with at least two folded-over edges, and at least two second plates (10), each provided with at least two folded-over edges. The plates are parallel to one another and perpendicular to the main axis of the panel. The panel includes at least one internal joining element (14) inserted between the first and second plates along the main axis.
