Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stability of sensor devices for detecting fill levels in containers is compromised by their length, which complicates mounting due to potential forces and moments, especially when cross-sections are limited.
Innovation Solution
A sensor device with a combined fastening principle using threaded and conical press-fit connections, ensuring a stable and detachable attachment of the sensor to the housing, utilizing separate mounting sections for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor device length is increased to ensure reliable measurement in large containers, then the measurement capability is improved, but the mounting stability deteriorates due to considerable forces and moments acting on the long sensor device
Solution Approach 1:
The patent combines two different fastening methods (threaded connection and conical press-fit connection) into a single mounting area, creating a hybrid fastening system that leverages the advantages of both methods to secure the long sensor device reliably
2Ease of manufacture
If simple screw fastening is used for mounting the sensor device, then the ease of manufacture is improved, but the mounting stability is insufficient for long sensor devices with considerable forces
Solution Approach 1:
The patent merges threaded connection and conical press-fit connection in a single mounting area, creating a hybrid fastening system that provides enhanced stability while remaining manufacturable
Solution Approach 2:
The mounting area is segmented into two separate fastening sections, each handling different aspects of the fastening requirement, allowing the system to meet both stability and manufacturability goals
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
The combined fastening method provides twice the stability of simple screw fastening, allowing secure attachment even with challenging length-to-diameter ratios, particularly relevant for long sensor devices.
Implementation Method 1
a second mounting section, separate from the first mounting section, for forming a conical press fit with a corresponding second mounting section of the sensor device
Implementation Method 2
forming a conical press fit
