Locking Swivel Hanger for Adjustable HVAC Unit Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for suspending HVAC units from ceilings restrict airflow direction, reducing efficiency and complicating installation and maintenance due to fixed positions, which limits flexibility and accessibility.
Innovation Solution
A locking swivel system with adjustable components, including a U-bar and telescoping hanger arms, allows for rotation and adjustable height, enabling optimal airflow direction and easier installation and maintenance by providing a pivoting connection between upper and lower hanging members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional strut channels and threaded rods are used to suspend HVAC units, then the installation structure is simple and straightforward, but the HVAC unit is fixed in position and cannot be adjusted, reducing flexibility and requiring excessive installation time for calculating optimal positions
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed suspension system into a movable one through the locking swivel mechanism. The swivel allows the HVAC unit to rotate and pivot to different positions, and when locked, maintains the desired position. This enables the system to adapt to different installation requirements while maintaining structural integrity.
Solution Approach 2:
The locking swivel system is divided into distinct functional components: the swivel mechanism for rotation, the locking mechanism for position fixation, and the mounting interfaces. This segmentation allows each component to perform its specific function independently, making the overall system both adaptable and manageable in complexity.
2Productivity
If HVAC units are installed in fixed positions based on ceiling joist orientation, then the installation process is straightforward, but the airflow direction is restricted and heating or cooling efficiency is reduced
Solution Approach 1:
The locking swivel mechanism enables the HVAC unit to be dynamically positioned during installation and maintenance. The unit can be rotated to optimal airflow positions and then locked, providing both installation flexibility and operational efficiency without requiring complex reinstallation procedures.
3Ease of repair
If traditional fixed suspension methods are used, then the structure is simple, but future maintenance and service become difficult when access panels are in inconvenient locations
Solution Approach 1:
The locking swivel system provides dynamic positioning capability that facilitates maintenance operations. When service is required, the locking mechanism can be released, allowing the HVAC unit to be rotated to positions that provide better access to panels and components, then relocked in the new position.

AI summary
An improved hanging apparatus with a locking swivel for suspending objects from an overhead structure is provided. The apparatus may advantageously be employed to suspend a heating, ventilation, and air conditioning (“HVAC”) unit from a ceiling, ceiling joists, beams, trusses, rafters, or the like of a room or space to be heated or cooled by the HVAC unit.
