Retaining Bracket for Applicator Rod in Fluid Spray Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil cleaning apparatuses for HVAC systems face difficulties in effectively applying cleaning fluids to hard-to-reach areas due to the disengagement of applicator wands under operating pressures, leading to inefficiencies and safety hazards.
Innovation Solution
A fluid spray delivery apparatus with a retaining bracket that secures the applicator rod to the siphon gun assembly, ensuring it remains attached and in fluid communication, even under hydraulic pressure, along with a hand-held spraying assembly that includes a siphon gun, tubing, and a retaining bracket to maintain connection during pressurized fluid application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an applicator wand is used to apply cleaning fluid under pressure, then cleaning effectiveness is improved, but the applicator may disengage from the spray unit
Solution Approach 1:
The applicator rod is nested within a retaining bracket that has an opening configured to receive the applicator rod. The retaining bracket is secured to the spray unit such that the applicator rod passes through the bracket, providing secure retention while allowing fluid application. This nesting structure prevents disengagement under pressure while maintaining cleaning effectiveness.
Solution Approach 2:
The retaining bracket serves as an intermediary component between the spray unit and the applicator rod. It provides a mechanical connection that secures the applicator rod to the spray unit, acting as a mediator that transfers and stabilizes the connection under hydraulic pressure conditions.
2Reliability
If the applicator rod is securely retained to prevent disengagement, then reliability is improved, but device complexity increases
Solution Approach 1:
The retention system is segmented into distinct functional components: the spray unit, the retaining bracket, and the applicator rod. The retaining bracket is a separate component with a specific geometric feature (opening) that receives the applicator rod, creating a simple yet effective retention mechanism without requiring complex assembly or additional fastening elements.
