Air conditioner drain pan platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning appliances face challenges in installation due to varying wall positions, requiring bespoke platforms that are time-consuming and costly, especially in multi-unit projects, as they need to be custom-made for each unit to ensure proper alignment and support.
Innovation Solution
A standardized platform with a drain pan that includes sockets for adjustable legs and a plenum attachment, allowing the air conditioner unit to rest on the drain pan's upper surface, which is designed to fit within a wall channel, providing structural support and facilitating easier installation by accommodating different installation heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a standardized platform is used, then installation time is reduced, but installation precision is worsened due to varying wall positions
Solution Approach 1:
The drain pan is designed with an adjustable leg assembly that can be extended or retracted to different lengths, allowing the platform to dynamically adapt to varying wall positions and plenum heights. This dynamic adjustment capability enables a standardized platform to achieve precise installation across different installation scenarios without requiring custom fabrication for each case.
Solution Approach 2:
The leg assembly includes an adjustable length mechanism that changes the vertical dimension parameter of the platform. By modifying the leg length parameter, the platform can compensate for variations in wall position and plenum height, maintaining proper alignment and support while using a standardized base design.
2Manufacturing precision
If bespoke platforms are constructed for each unit, then installation precision is improved, but device complexity increases
Solution Approach 1:
The standardized drain pan platform is designed to serve multiple installation scenarios through its adjustable leg assembly. Rather than creating different platform designs for different wall positions, the universal platform with adjustable legs can adapt to various plenum heights and wall positions, reducing the number of unique platform designs needed while maintaining installation precision.
Solution Approach 2:
The platform is segmented into a standardized base structure and an adjustable support mechanism. This segmentation allows the base to remain simple and standardized while the adjustable leg assembly handles the complexity of adapting to different installation conditions, effectively separating the fixed and variable components of the platform design.
3Manufacturing precision
If bespoke platforms are constructed for each unit, then installation precision is improved, but productivity decreases
Solution Approach 1:
The standardized drain pan platform is pre-manufactured with an adjustable leg assembly that can be quickly configured during installation. This preliminary preparation of the platform structure eliminates the need for on-site custom fabrication, allowing installers to simply adjust the leg length to match the specific installation conditions rather than building a custom platform from scratch for each unit.
Solution Approach 2:
The adjustable leg assembly provides dynamic adaptability that allows rapid adjustment to different installation heights and wall positions. This dynamic feature enables a single standardized platform design to replace multiple custom-built platforms, significantly improving installation speed while maintaining the precision needed for proper alignment with varying plenum positions.

AI summary
An air conditioning appliance includes a housing, a drain pan positioned below the housing, and a plenum which is attached to the housing and to the drain pan. The drain pan includes an upper surface in contact with the housing and a socket configured to receive a leg. The housing of the air conditioning appliance rests on the upper surface of the drain pan, such that the drain pan defines a platform which structurally supports the housing of the air conditioning appliance.
