Integrated Utility Pad and Security Cage for Fast AC Condenser Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility pads for air conditioner condensers lack structural integrity, are prone to degradation, and are difficult to install, while security cages have weak structures and complex installations, with no integration of mounting features between the two.
Innovation Solution
A lightweight composite utility pad with recesses for ballast and horizontal flange to prevent sinking, combined with a security cage of solid steel bars and adjustable mounting features that secure to the pad, allowing for easy installation and adjustment to fit various equipment sizes, and can be retrofitted to existing pads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If pre-manufactured concrete composite pads are used, then structural strength is improved, but weight increases making them difficult to handle and install by one person
Solution Approach 1:
The utility pad is segmented into a two-part system: a lightweight composite pad body and separate ballast elements. This segmentation allows the main pad structure to remain lightweight and easy to handle, while the ballast can be added separately to achieve the required weight for stability in high-wind areas.
Solution Approach 2:
The utility pad uses composite materials (such as fiberglass-reinforced plastic or polymer-concrete composites) that provide high strength-to-weight ratio. This allows the pad to maintain structural integrity and strength comparable to solid concrete while being significantly lighter and easier to install by one person.
2Ease of manufacture
If security cages with thin-walled structure are used, then ease of manufacture is improved, but structural strength deteriorates
Solution Approach 1:
The security cage uses composite construction combining steel bars (for strength) with concrete infill (for rigidity and mass). This composite structure provides superior strength compared to thin-walled steel alone, while the concrete infill also adds security and deterrence.
Solution Approach 2:
The security cage employs varying wall thicknesses and reinforcement densities at different locations. Critical areas have thicker walls and additional reinforcement, while less critical areas use standard thickness. This local quality approach optimizes strength where needed while maintaining ease of manufacture overall.
3Adaptability or versatility
If security cages with complex installation procedures are used, then adaptability is improved, but installation time increases
Solution Approach 1:
The security cage is designed with pre-assembled modular sections and pre-positioned mounting features that align with standard utility pad configurations. This preliminary preparation allows for rapid installation by simply bolting the cage to the pad without complex field assembly or customization.
Solution Approach 2:
The security cage uses standardized mounting features and connection mechanisms that can be adapted to various utility pad types and equipment configurations. This universality provides adaptability to different applications while maintaining simple, consistent installation procedures across all installations.
4Ease of manufacture
If utility pads without integrated mounting features are used, then ease of manufacture is improved, but adaptability deteriorates
Solution Approach 1:
The utility pad incorporates integrated mounting features (such as embedded anchor bolts, flanges, or attachment points) that are universally compatible with standard security cage configurations. These features are built into the pad manufacturing process, providing adaptability to various security cage types without complicating the pad's basic construction.

AI summary
A utility pad arrangement for mounting outdoor equipment such as air conditioner condensers thereon, having a flat, plate-like pad body with a plurality of recesses around its periphery. Mounting devices are provided and are shaped to nest within the recesses for optionally adding a security cage formed out of strap-like bars to securely surround the equipment located on the pad body in association with the mounting devices.
