Z-Shaped Cabin Air Compressor Bracket for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cabin air compressor brackets for aircraft environmental control systems lack a robust and efficient structural design that effectively supports the cabin air compressor and mount, leading to potential instability and vibration issues during operation.
Innovation Solution
A support bracket with a planar support portion, mounting portions, and support ribs that provide structural support and secure mounting for the cabin air compressor, featuring specific surface orientations, hole configurations, and rib engagements to ensure stability and alignment, forming a z-shaped configuration for enhanced structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple bracket design is used, then manufacturing cost and complexity are reduced, but structural stability and vibration resistance deteriorate
Solution Approach 1:
The bracket is divided into multiple functional segments including a support portion, first mounting portion, second mounting portion, and multiple support ribs. This segmentation allows each part to perform its specific function while maintaining overall structural stability without excessive complexity.
Solution Approach 2:
The bracket employs a z-shaped configuration that extends in multiple dimensions, providing structural integrity through three-dimensional positioning rather than simple planar design. This dimensional approach enhances stability while maintaining manufacturing feasibility.
2Manufacturing precision
If mounting holes and coupling holes are positioned optimally, then alignment precision is improved, but manufacturing complexity increases
Solution Approach 1:
The bracket's mounting portion and second mounting portion both define holes that serve dual purposes: alignment during assembly and structural connection. This multi-functionality achieves precise alignment without requiring additional alignment features that would increase complexity.
Solution Approach 2:
The support ribs are positioned to engage surfaces in advance of final assembly, pre-establishing alignment paths that guide the compressor and mount into correct positions during installation, thereby achieving precision without complex adjustment mechanisms.
3Strength
If support ribs engage multiple surfaces, then structural strength is improved, but manufacturing precision requirements increase
Solution Approach 1:
The support ribs are designed with specific local geometries that engage particular surfaces (first surface, second surface, third surface, fourth surface) with optimized contact areas. This local quality approach distributes loads effectively while tolerating normal manufacturing variations.
Solution Approach 2:
The multiple surface engagements of the support ribs create redundant load paths that compensate for minor manufacturing variations. The rib structure inherently cushions against precision deviations by distributing stresses across multiple engagement points.

AI summary
A support bracket has a support portion, a first mounting portion, and a second mounting portion. The first mounting portion extends from a first end of the support portion. The second mounting portion extends from a second end of the support portion. The second mounting portion defines a coupling hole that is disposed proximate an end surface of the second mounting portion. A first support rib engages a first surface of the support portion and a third surface of the first mounting portion.
