Compressor Baseplate Annular Rib Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressor housings with domed shapes require additional mounting feet or spacers to maintain upright positioning during handling and mounting, increasing overall height and necessitating complex mounting systems, especially in tandem or multiple compressor configurations.
Innovation Solution
A compressor assembly with a base plate featuring an annular rib and convex central portion, allowing direct mounting onto base rails without additional feet or spacers, providing structural strength and increased oil volume without height increase, fabricated from sheet metal with integrated stiffening features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional mounting feet or spacers are added to domed compressor housings, then the compressor can be mounted upright, but the overall height increases and device complexity increases
Solution Approach 1:
The base plate merges the mounting function with the housing structure itself. The flat outer peripheral region of the base plate serves as both the mounting surface for attaching the compressor to rails and the structural base, eliminating the need for separate mounting feet or spacers. This integration resolves the contradiction by providing mounting capability without increasing overall height.
Solution Approach 2:
The base plate utilizes the radial dimension by extending outward from the central dome to create a flat outer peripheral region. This dimensional approach allows the mounting surface to be distributed laterally rather than vertically, enabling stable mounting without increasing the compressor's height dimension.
2Ease of operation
If additional mounting feet or spacers are added to domed compressor housings, then the compressor can be mounted upright, but device complexity increases
Solution Approach 1:
The base plate combines multiple functions into a single component: it serves as the housing bottom, provides structural support through the central dome, creates oil reservoir space, and provides the mounting surface through its flat outer peripheral region. This multi-functionality eliminates the need for separate mounting feet, spacers, or adapters, thereby reducing device complexity.
Solution Approach 2:
The base plate is designed as a universal component that performs multiple functions simultaneously - housing containment, oil reservoir formation, and mounting surface provision. This multi-functional design simplifies the overall mounting system by eliminating the need for multiple specialized components.
3Ease of manufacture
If the base plate is made from thinner sheet metal, then manufacturing efficiency improves, but structural strength decreases
Solution Approach 1:
The central dome structure utilizes curved sheet metal formation to create a rigid, load-bearing structure. The domed shape inherently provides structural strength while allowing the use of thinner gauge material compared to flat plates, as the curvature distributes stresses more effectively.
Solution Approach 2:
The base plate features varying structural characteristics in different regions: the central dome provides rigid support and oil reservoir containment, while the flat outer peripheral region provides mounting surface area. This local differentiation allows optimization of material usage - thinner gauge can be used in the flat mounting region while maintaining sufficient thickness in the domed support region.
