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

VSEngineering 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

Engineering Contradiction:
Improvepanel assemblyVSAvoidjoining elements
Core Design Contradiction:
Ease of manufactureVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvepanel weightVSAvoidair tightness
Core Design Contradiction:
Weight of moving objectVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveair tightnessVSAvoidpanel handling
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #1Segmentation

4Strength

If heavy panels with metal joining elements are used, then structural rigidity is ensured, but production costs increase and handling becomes difficult

Engineering Contradiction:
Improvepanel rigidityVSAvoidproduction cost
Core Design Contradiction:
StrengthVSEase of manufacture

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.

Inventive Principle:
Principle #40Composite materials
