Solution Overview

Problem

Current air handling units are limited in accessing air filters due to their specific design, requiring either lateral or lower access, which restricts flexibility and maintenance, especially when installed in false ceilings.

Innovation Solution

The air handling unit design allows for angled access to air filters through both side and lower portions, featuring a support structure with rail and guiding mechanisms, enabling movement and fixing of air filters via misaligned guide elements and slots, and pressure-fixing profiles, accommodating different filter dimensions and installation orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If air handling units are specifically designed with lateral or lower access to air filters, then the structural design is simplified, but the flexibility and ease of maintenance are reduced

Engineering Contradiction:
ImproveAccess to air filterVSAvoidSupport structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure is divided into modular components including a support body, guide rails, and movable support arms that can independently position themselves. This segmentation allows the structure to adapt to different access requirements without redesigning the entire system, resolving the contradiction between operational ease and structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support structure incorporates movable support arms with guide elements that can dynamically adjust their position along guide rails. This dynamic capability enables the structure to provide optimal access to air filters regardless of installation location, eliminating the need for specific lateral or lower access designs while maintaining structural integrity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If air filters are accessed through fixed lateral or lower openings, then the manufacturing process is simplified, but the adaptability to different installation conditions is reduced

Engineering Contradiction:
ImproveInstallation flexibilityVSAvoidSupport structure
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The support structure is designed as a universal system that can accommodate various air filter sizes and installation orientations. The movable support arms and adjustable guide rails enable the same structure to serve multiple access configurations (lateral, lower, or angled), providing installation flexibility without requiring multiple specialized designs.

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

Solution Approach 2:

The support structure allows for parameter adjustments in terms of support arm position, angle, and extension distance. These parameter changes enable adaptation to different installation conditions and air filter dimensions while maintaining a standardized manufacturing process for the base structure.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If air handling units are installed in false ceilings, then the visual appearance is improved, but the accessibility for maintenance is reduced

Engineering Contradiction:
ImproveMaintenance accessVSAvoidAccess mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The movable support arms act as intermediaries between the fixed air handling unit housing and the air filters. These arms can extend and retract to provide access to filters located in hard-to-reach positions within the false ceiling installation, reducing maintenance difficulty without requiring complex external access mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The support structure utilizes three-dimensional movement capabilities with support arms that can extend in multiple directions and angles. This dimensional flexibility allows maintenance personnel to access air filters from various directions even when the unit is installed in confined false ceiling spaces, improving maintenance accessibility without adding complex external mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
