Portable Davit System with Clamp Mount for Single-Person AC Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing davit systems are not designed for temporary mounting on air conditioning units for servicing, lacking portability and adjustability for efficient maintenance by a single person.
Innovation Solution
A portable davit system comprising a davit arm and mount with a clamping mechanism and arm mounting element, allowing for easy installation and removal of the air conditioning unit head, enabling a single person to pivot and lift the head for servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a davit system is designed for permanent installation on air conditioning units, then it provides stable support for head removal, but it reduces portability and increases installation complexity
Solution Approach 1:
The davit system is divided into separate components: a davit arm assembly and a mounting bracket assembly. The mounting bracket can be independently attached to the air conditioning unit corner flange, while the davit arm can be attached to the bracket only when needed for head removal. This segmentation allows the system to be portable yet provide stable support when installed.
2Force
If a davit system is designed to handle heavy air conditioning heads, then it provides sufficient lifting capacity, but it increases the size and weight of the system
Solution Approach 1:
The davit arm is designed to pivot on a horizontal axis, allowing the operator to manually position and hold the air conditioning head at various angles during removal and installation. The pivot mechanism and counterbalancing design reduce the effort required to handle heavy heads, enabling a single operator to manage weights that would otherwise require multiple people or a motorized system.
3Device complexity
If a davit system uses fixed mounting positions, then it simplifies the mounting structure, but it reduces adaptability to different air conditioning unit sizes
Solution Approach 1:
The mounting bracket includes adjustable features that allow it to accommodate different corner flange positions and orientations on various air conditioning unit models. The bracket can be positioned at different locations on the unit, and the davit arm pivots on a horizontal axis to adjust to different head weights and dimensions, providing adaptability without requiring complex custom mounting structures for each unit type.

AI summary
A davit system has a davit arm and a davit mount. The davit mount includes a mount body, a clamping mechanism for clamping the corner flange of the air conditioning unit, and an arm mounting element for pivotally mounting the davit arm on the davit mount. When the mount body is mounted on the corner flange of the air conditioning unit, the davit arm extends laterally over the head of the air conditioning unit, and pivots away from the air conditioning unit for removing the head during servicing.
