HVAC Valve Package Support Bracket for Shipping Line Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heating and cooling equipment components, such as supply and return lines, are prone to damage during shipping due to pre-assembly practices, leading to increased costs for repairs.
Innovation Solution
A support system comprising hinged frames, screws, threaded holes, and support brackets encases supply and return lines within a duct assembly, preventing misuse and damage during shipping by eliminating handles and providing adjustable tension to secure the lines without causing lateral force damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heating and cooling equipment is pre-assembled before shipping, then manufacturing efficiency and productivity are improved, but the supply and return lines become vulnerable to damage during shipping
Solution Approach 1:
The supply and return lines are pre-positioned and secured to the coil assembly before shipping using hanger assemblies with adjustable tensioning mechanisms. This preliminary securing action allows the equipment to be pre-assembled for manufacturing efficiency while protecting the lines from damage during shipping through proper tension control and secure attachment.
2Stability of the object's composition
If supply and return lines are securely attached to the coil assembly, then assembly stability is improved, but the lines may be damaged by excessive tension or lateral force during shipping
Solution Approach 1:
The hanger assembly incorporates adjustable tensioning mechanisms that allow the securing force to be dynamically controlled. The tension can be adjusted to provide sufficient stability to prevent line dislodgement while avoiding excessive force that could cause damage. This dynamic adjustment capability resolves the contradiction between needing secure attachment and avoiding damage from excessive tension.
3Ease of operation
If the HVAC assembly includes integrated support structures for supply and return lines, then ease of shipping and handling is improved, but the device complexity increases
Solution Approach 1:
The hanger assembly serves multiple functions: it secures the supply and return lines to the coil assembly, provides adjustable tensioning, and facilitates easy installation and removal. By consolidating these multiple functions into a single integrated component, the solution improves ease of shipping and handling while minimizing the increase in device complexity compared to using separate components for each function.

AI summary
A heating, ventilating and air conditioning (HVAC) assembly that includes a duct and a coil assembly coupled to the duct. A supply line and return line are connected to the coil assembly. A first hanger assembly encircles the supply line, and a second hanger assembly encircles the return line. A support bracket has a first raised channel with a hole and second raised channel with a hole. A first threaded connector is secured using a square nut located in under the raised channel of the bracket, and a second threaded connector is connected to the threaded hole of the second hanger assembly and the second hole in a raised channel of a bracket and secured using a square nut located in under the raised channel of the bracket.
