Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air handling units are cumbersome and require skilled assemblers for complex installation, leading to delays and increased costs due to their large size and intricate assembly processes, which complicates transportation and assembly within building spaces.
Innovation Solution
A modular air handler design that allows for simplified assembly and transportation by dividing the system into distinct modules with sliding coupling mechanisms between module frames and case panels, reducing the number of assembly operations and eliminating the need for extensive screw fastening, enabling assembly by non-skilled personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional air handling units are designed with frames and panels coupled using thousands of screws, then coupling strength and air leakage prevention are improved, but assembly complexity and installation time increase significantly
Solution Approach 1:
The air handling unit is divided into modular sections with standardized coupling interfaces. Each module can be assembled independently and then connected to form the complete unit, reducing the overall assembly complexity while maintaining sealing integrity through standardized gasket and fastening systems.
Solution Approach 2:
The traditional screw-fastening system is replaced with a clip-based mechanical coupling system. Clips engage with corresponding receptacles on the frames and panels, providing sufficient coupling strength and air tightness without requiring thousands of screws, thereby dramatically simplifying the assembly process.
2Strength
If air handling units are designed as complete large-scale assemblies, then structural integrity is maintained, but transportation and on-site assembly become prohibitively complex
Solution Approach 1:
The air handling unit is segmented into multiple transportable modules that can be moved individually to the installation site. Each module maintains its structural integrity through optimized frame designs, and the modules are subsequently connected using the simplified clip-coupling system to form the complete unit with full structural strength.
Solution Approach 2:
Critical assembly operations are performed at the manufacturing site before transportation, including pre-attaching panels to frames using the clip system and pre-installing internal components. This preliminary assembly reduces on-site work requirements while ensuring structural integrity is established before the unit is transported.
3Strength
If traditional assembly methods using numerous screws are employed, then coupling strength is sufficient, but skilled assemblers are required and installation costs increase
Solution Approach 1:
The complex screw-fastening mechanism is substituted with a simple clip-based coupling system. The clips are designed to engage with recesses in the frames and panels, providing adequate coupling strength through mechanical interlocking and friction, while eliminating the need for specialized tools and skilled assembly operations.
Solution Approach 2:
The clip coupling system is designed to be self-aligning and self-locking. As panels are positioned on the frames, the clips automatically engage with the corresponding receptacles, providing secure attachment without requiring precise alignment or specialized assembly skills, thereby enabling unskilled personnel to perform the assembly.

AI summary
An air handler which allows modular assembly at a place of manufacture or outside of a building and modular transportation to a machine room of the building where the air handler will be installed, thereby achieving enhanced transportation convenience. In addition, in the air handler, a plurality of case panels may be assembled with a plurality of module frames via considerably simplified sliding coupling, providing excellent hermetic sealing. As such, manufacturing costs may be reduced due to a reduction in a number of components, and assembly time may be remarkably reduced due to a reduced number of assembly operations. This advantageously results in reduced labor costs and enhanced air conditioning efficiency.
