Sensor Housing with Oblique Thread for Groove Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor housings face challenges in secure attachment, ease of assembly, space efficiency, fastener loss prevention, and compatibility with various groove geometries, particularly with 'drop-in' mounting methods, which are complex, expensive, and often require additional space or increase sensor length.
Innovation Solution
A sensor housing with a ledge-like housing projection featuring flat side surfaces and an obliquely arranged thread for a fastening screw, allowing direct perpendicular insertion and secure fastening without undercuts, enabling easy assembly, secure attachment, and compatibility with diverse groove geometries, while using a conductive thread for electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drop-in mounting is used with C-slot and round undercut, then installation is simplified, but secure attachment cannot be achieved due to tolerance variance
Solution Approach 1:
The patent changes the geometric parameters of the mounting interface by replacing the round undercut with a flat-sided housing projection that has flat side surfaces. This parameter change allows the sensor housing to be securely attached to various groove geometries while maintaining simple installation procedures.
2Reliability
If complex fastenings like eccentrics or clamping jaws are used, then attachment security is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent merges the fastening function directly into the sensor housing structure itself. The housing projection with flat side surfaces and the groove form an integrated attachment system, eliminating the need for separate complex fastening components like eccentrics or clamping jaws.
Solution Approach 2:
The housing projection design serves multiple functions: it provides structural support, enables secure attachment to various groove geometries, and simplifies installation. This multi-functional design replaces multiple specialized fastening components with a single universal attachment mechanism.
3Reliability
If clamping jaws or sliding blocks are used for secure attachment, then attachment security is improved, but sensor length increases
Solution Approach 1:
The patent nests the attachment functionality within the existing sensor housing structure. The housing projection is an integral part of the sensor housing that extends into the groove, eliminating the need for external clamping components that would increase the overall sensor length.
4Ease of operation
If conventional fastenings are used, then attachment is achieved, but fasteners can be lost during assembly or disassembly
Solution Approach 1:
The patent merges the fastening mechanism with the housing structure itself. The thread is formed directly in the housing projection, and the groove structure retains the fastening screw, eliminating the risk of fastener loss that occurs with separate conventional fastening components.
