Two-Part Fluid Sensor Housing for Flexible Duct Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid sensing devices face challenges in being mounted in limited spaces due to their fixed form factors, which restricts their installation in various orientations and configurations, especially in ventilation ducts where space constraints vary.
Innovation Solution
A fluid sensing device comprising two housing portions that can be connected in geometrically different configurations using mechanical fastening and electrical interconnection means, allowing for flexible mounting orientations such as angular, curved, or transverse displacements, with multiple sets of electrical interconnection means to accommodate various space constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed form factor is used for the sensing device, then the device structure is simple and easy to manufacture, but the device cannot be mounted in limited spaces with varying orientations
Solution Approach 1:
The housing is divided into two separate portions: a first housing portion that accommodates the sensing element and a second housing portion that accommodates electrical connection components. These portions can be connected in different geometrical configurations using mechanical fastening means and electrical interconnection means, enabling flexible mounting in limited spaces while maintaining a relatively simple overall structure.
2Reliability
If the second housing portion is shielded from the first housing portion, then electrical components are protected from fluid exposure and harmful substances, but the device requires more space for separation
Solution Approach 1:
The housing is segmented into two portions that can be positioned at different locations relative to each other. The second housing portion containing electrical components can be shielded from the first housing portion containing the sensing element, protecting electronics from fluid exposure while allowing compact arrangement that minimizes overall device volume.
