Aircraft Conveying Device Segmentation for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft air-conditioning unit conveying devices are complex to maintain due to the integrated nature of mechanical and electrical components, making fault isolation and replacement difficult, especially in confined spaces like aircraft.
Innovation Solution
A detachable design for the mechanical and electrical units of the conveying device, where the mechanical unit remains installed while the electrical unit can be easily removed and replaced, allowing for modular maintenance without altering the device's dimensions or interfaces, utilizing a non-destructive fastening system and interface elements for secure electrical connections and cooling fins for thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mechanical unit and electrical unit are integrated in a single conveying device, then the device structure is compact and space-efficient, but maintenance becomes complex and time-consuming due to difficulty in fault isolation and component replacement
Solution Approach 1:
The conveying device is divided into two detachable units: a mechanical unit (with fan blade and housing) and an electrical unit (with electric motor). These units can be separated from each other, allowing independent maintenance and replacement of each unit without affecting the other, thus resolving the contradiction between compactness and ease of repair
2Ease of manufacture
If the conveying device is designed with fixed dimensions and interfaces for installation, then the device can be easily installed in confined aircraft spaces, but maintenance requires creating large disassembly spaces which is difficult in confined environments
Solution Approach 1:
By segmenting the device into detachable mechanical and electrical units with standardized connection interfaces, the invention allows the device to be installed as a compact integrated unit while enabling easy separation during maintenance. The interfaces are designed to accommodate installation in confined spaces, and the detachable design allows maintenance to be performed by simply separating the units without requiring large disassembly spaces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies maintenance by allowing faulty units to be replaced independently, reducing maintenance time and space requirements, while maintaining the device's compactness and protecting electronic components from environmental influences.
Implementation Method 1
An electric motor serves as the drive element for propelling the rotor
Implementation Method 2
The housing of the electrical unit is open on its side facing towards the mechanical unit, and the conveying device can be made particularly lightweight without impairing the protective function of the housing, since the electronic components arranged in the housing are protected from environmental influences, on the one hand by the housing and on the other hand by the mechanical unit
