Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft environmental control systems face challenges in reducing ozone levels at high altitudes, as existing ozone converters are not efficiently integrated with flow measurement capabilities, leading to inefficiencies and complexities in packaging within limited aircraft spaces.
Innovation Solution
A flow sensing ozone converter design that includes an inlet housing, outlet housing, ozone converter core, and a flow sensor assembly with heat shield and pressure sensors, allowing for removably coupled components and an insulation blanket to enhance ozone conversion performance and simplify installation, while providing integrated flow sensing and oxygen removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing ozone converters are used without flow measurement integration, then the device complexity is reduced, but the measurement precision and productivity are worsened
Solution Approach 1:
The patent combines the flow sensor assembly with the ozone converter housing, integrating measurement functionality into the existing converter structure. The flow sensor assembly including pressure sensors and heat shield is merged with the inlet housing, eliminating the need for separate external flow measurement devices while maintaining measurement precision.
Solution Approach 2:
The ozone converter is designed to perform multiple functions simultaneously: ozone conversion and flow rate measurement. The housing serves both as the converter enclosure and as the mounting structure for flow sensing components, allowing a single device to fulfill both ozone removal and flow monitoring roles.
2Ease of repair
If the ozone converter core is permanently installed, then the reliability is improved, but the ease of repair and productivity are worsened
Solution Approach 1:
The converter is divided into separable components: the ozone converter core and the housing assembly. The core can be independently removed and replaced through the opening in the housing, allowing maintenance personnel to swap out the core without replacing the entire converter assembly, thus improving ease of repair while maintaining system reliability.
3Ease of manufacture
If the converter components are permanently coupled, then the reliability is improved, but the ease of manufacture and productivity are worsened
Solution Approach 1:
The coupling between components transitions from permanent to removable/dynamic. The housing and core are designed with complementary features (opening and insertable core) that allow for easy assembly and disassembly while maintaining a secure connection during operation, facilitating both manufacturing flexibility and operational reliability.
