Threaded Sensor Sleeve for Linear Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern reciprocating engines, the varying distances between sensor mounting points and measurement points, as well as the need for adjustable sensor positions during operation, pose challenges in accurately and easily setting and maintaining the correct sensor placement.
Innovation Solution
A measurement sensor design featuring an elongated sensor part with a first sleeve part for attachment, a second sleeve part rotatably arranged inside for adjustment, and an external screw thread on the sensor part and internal thread on the second sleeve part, allowing for longitudinal movement without rotating the sensor itself, along with a locking nut for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor part is rotated to adjust its position, then the sensor position can be changed, but the cable must be removed or the sensor must be accessible from the opposite side
Solution Approach 1:
The second sleeve part is nested inside the first sleeve part, with the sensor part threaded into the second sleeve part. This nested configuration allows the sensor to be adjusted by rotating the inner second sleeve part while the outer first sleeve part remains stationary and attached to the mounting surface, eliminating the need to remove cables or access the opposite side.
Solution Approach 2:
The sensor assembly is divided into three separate sleeve parts: a first sleeve part for mounting, a second sleeve part for adjustment, and the sensor part itself. This segmentation allows independent rotation of the second sleeve part to adjust sensor position while the first sleeve part remains fixed, solving the cable access problem.
2Ease of operation
If a simple adjustment mechanism is used, then the device is easier to operate, but the set distance cannot be maintained in demanding environments
Solution Approach 1:
The threaded connection between the sensor part and second sleeve part creates a self-locking mechanism. When the sensor part is rotated to adjust its position, the threads automatically maintain the set distance through friction and mechanical interference, eliminating the need for additional locking components while ensuring the position remains stable in demanding environments.
3Adaptability or versatility
If the sensor part is made adjustable, then it can accommodate varying distances, but the structural complexity increases
Solution Approach 1:
Instead of making the sensor part itself rotatable (which would complicate cable management), the invention inverts the approach by making the sleeve part surrounding the sensor rotatable. The second sleeve part rotates while the sensor part remains stationary, providing adjustability without increasing sensor complexity or affecting cable routing.
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
Enables easy and accurate adjustment of the sensor position relative to the mounting and measurement points, maintaining the set distance even in demanding environments without requiring cable removal or access from the opposite side, ensuring precise monitoring and control.
Implementation Method 1
the sensor part comprises an outer screw thread and the second sleeve part comprises an internal screw thread, the outer thread of the sensor part and the inner thread of the second sleeve part being attached to each other so that when the second sleeve part is rotated in relation to the sensor part, the sensor part moves in the direction of its longitudinal axis in relation to the first and second sleeve parts

AI summary
A measurement sensor includes an elongated sensor part at the first end of which is the electrical connection of the sensor part and at the second end of which is the sensor end of the sensor part. A first sleeve part is arranged around the sensor part for attaching the measurement sensor to the object to be measured and for supporting the sensor part. A second sleeve part extends into the first sleeve part, the second sleeve part being rotatably arranged in connection with the first sleeve part. The sensor part has an external thread and the second sleeve part has an internal thread, the external thread of the sensor part and the internal thread of the second sleeve part are connected to each other so that when the second sleeve part is rotated in relation to the sensor part, the sensor part moves in the direction of its longitudinal axis in relation to the first and second sleeve parts.
