Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air flow detection and measurement systems face disruptions due to direct contact between air/gas and detectors, which affects measurement accuracy and efficiency.
Innovation Solution
An instrument housing with wedge-shaped portions and flexible hinge connections that allow it to conform to curved surfaces, minimizing interference with air flow and enhancing aerodynamic efficiency, thereby improving measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detector is placed in direct contact with moving air or gas for measurement, then measurement capability is improved, but the flow is disrupted and measurement accuracy deteriorates
Solution Approach 1:
A thin membrane acts as an intermediary between the air flow and the detector. The membrane allows air molecules to pass through to the detector for measurement while maintaining a streamlined shape that minimizes flow disruption. This resolves the contradiction by mediating between the need for direct contact (measurement) and the need to avoid disruption (accuracy).
Solution Approach 2:
The housing and membrane are designed with curved, aerodynamic shapes that follow the contours of the aircraft surface. This curvature allows the detector assembly to blend smoothly with the airflow, reducing turbulence and flow disruption while still enabling measurement capability.
2Strength
If a rigid housing structure is used for the instrument, then structural strength is improved, but adaptability to curved surfaces deteriorates
Solution Approach 1:
The housing is divided into multiple segments or portions that can flex relative to each other through hinge connections. This segmentation allows the overall structure to conform to curved surfaces while each individual segment maintains sufficient structural strength. The hinge portions act as flexible joints that enable adaptation without compromising the integrity of the individual housing sections.
3Adaptability or versatility
If the housing is made flexible to conform to curved surfaces, then adaptability is improved, but structural rigidity deteriorates
Solution Approach 1:
The housing is divided into multiple rigid segments connected by flexible hinge portions. This segmentation allows the structure to achieve flexibility for conforming to curved surfaces while each segment maintains its own rigidity and structural integrity. The hinge portions provide the necessary flexibility without requiring the entire housing to be柔弱.
Solution Approach 2:
The housing employs composite construction combining rigid materials for the housing portions with flexible materials for the hinge connections. This composite approach allows the structure to exhibit both rigidity (for strength and stability) and flexibility (for adaptability to curved surfaces), resolving the contradiction between these opposing requirements.
