Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air generating systems with electromechanical devices face integration challenges in aircraft due to large volumes and parasitic radiation from segregated electronic components, requiring multiple inter-card connections that increase volume and electromagnetic emissions.
Innovation Solution
A casing with two parts forming a closed recess and channels that house a single electronic card for power and control, eliminating the need for a central air duct and inter-card connections, reducing volume and electromagnetic emissions while allowing airflow for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are attached to the exterior edges of the duct or distributed between multiple electronic cards, then the device can be powered and controlled, but the volume occupied around the air inlet stream becomes large and parasitic radiation increases
Solution Approach 1:
The patent merges the air inlet duct and electronic card support structure into a single integrated casing. The casing has a hollow interior that simultaneously serves as the air inlet passage and the mounting structure for electronic components, eliminating the need for separate support structures and reducing overall volume.
Solution Approach 2:
The casing serves multiple functions: it forms the air inlet stream duct, provides structural support, houses electronic components, and acts as a protective enclosure. This multi-functionality eliminates the need for separate components for each function, reducing the total volume occupied.
2Reliability
If multiple electronic cards are used to house electronic components, then the device can be controlled and powered, but inter-card connections are required which increase parasitic radiation and device complexity
Solution Approach 1:
The patent consolidates multiple electronic cards into a single electronic card that integrates all necessary control and power supply functions. This single card is mounted within the casing hollow, eliminating the need for inter-card connections and reducing electromagnetic interference.
3Speed
If a central air circulation duct is created, then air can be supplied to the electromechanical device, but volume is occupied that could be used for electronic components
Solution Approach 1:
The air circulation duct and electronic component housing are merged into a single structure. The hollow interior of the casing serves as both the air passage and the mounting space for electronic cards, eliminating the need for separate volume allocation.
Solution Approach 2:
The casing hollow serves dual purposes: it guides air flow to the electromechanical device and simultaneously provides mounting space for electronic components. This multi-functionality maximizes space utilization without compromising air supply performance.
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 reduces the volume and mass of control and power electronics, improves reliability, and minimizes parasitic radiation, enabling more efficient integration in aircraft while maintaining performance and reducing manufacturing costs.
Implementation Method 1
each part comprising a hollow wall defining a channel extending between the two ends of the casing, each channel opening in front of the air inlet opening so that the electromechanical device is supplied with air routed by the channels
Implementation Method 2
the air aspirated by the device is routed in the interior of the channels along the recess formed by the assembly of the parts of the casing, thus allowing the cooling of the electronic components of the device, the heat emitted by the latter being removed via the circulation of air through the channels
