Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air handling units (AHUs) in HVAC systems are prone to dislodgment during seismic activity, posing a risk of falling and causing potential damage or injury due to inadequate mounting solutions.
Innovation Solution
A mount assembly comprising a base with an internal screw thread and a resilient element with an external screw thread for secure engagement, along with a carriage that can slide on a support rail, providing adjustable leveling and vibration absorption to mitigate seismic vibrations and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid mounting solution is used for AHUs, then the attachment strength is improved, but the vulnerability to seismic dislodgment increases
Solution Approach 1:
The patent changes the physical state of the mounting element from rigid to resilient/elastomeric. The resilient element can deform elastically under seismic loads, absorbing energy while maintaining attachment integrity. This parameter change allows the mounting to both hold the AHU securely and withstand seismic events without dislodgment.
Solution Approach 2:
The mounting assembly uses a composite structure combining a rigid base (for structural support and strength) with a resilient elastomeric element (for seismic absorption). This composite approach integrates both the strength requirement and the seismic resistance requirement into a single assembly that satisfies both contradictory demands.
2Ease of manufacture
If a fixed mounting position is used for AHUs, then the installation simplicity is improved, but the adjustability for leveling is reduced
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism where the resilient element can be positioned at different heights or orientations during installation. The elastomeric material's inherent flexibility allows for adjustment while maintaining a fixed mounting structure, enabling leveling adaptation without complicating the overall installation process.
3Stability of the object's composition
If a rigid base is used for mounting, then the structural stability is improved, but the vibration absorption capability is reduced
Solution Approach 1:
The resilient elastomeric element acts as an intermediary between the rigid base and the AHU. It transmits necessary structural loads while filtering out harmful vibrations and seismic shocks. This intermediary layer absorbs and dissipates vibrational energy, preventing its transmission to the mounted equipment while maintaining structural stability.

Function Achieved in This Case
The mount assembly effectively absorbs seismic vibrations and noise, reducing the likelihood of AHUs breaking free from their mounts and causing damage or injury, while allowing for easy adjustment and secure attachment.
Implementation Method 1
a resilient element (6) comprising an item attachment point (4), and which interposes the item attachment point (4) and the base (2), wherein the resilient element (6) is capable of absorbing violent shock loads associated with seismic activity
