Vernier Sensor Mount for Precise Mechanical Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sensor mounting arrangements require complex calibration and signal compensation due to variations in sensor position and orientation, leading to processing overhead and inconvenient setup, especially in applications with manufacturing tolerances and limited space.
Innovation Solution
A mechanical vernier adjustment mechanism allows for precise positional and orientational alignment of sensors, eliminating the need for electronic or software calibration by using arrays of alignment features such as notches or circular arcs, enabling consistent signal output across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mounting arrangements are used with adhesive or standard positioning methods, then installation is simple, but sensor position and orientation vary due to manufacturing tolerances requiring complex calibration and software compensation
Solution Approach 1:
The patent replaces software-based calibration and compensation mechanisms with a purely mechanical adjustment system. The sensor mount includes adjustable positioning features that allow mechanical calibration of sensor position and orientation during assembly, eliminating the need for complex post-installation software calibration procedures while maintaining simple installation processes
Solution Approach 2:
The patent implements preliminary mechanical adjustment capabilities in the mounting structure itself, allowing sensor position and orientation to be calibrated during the assembly process before final installation. This preliminary mechanical calibration prevents the accumulation of errors that would otherwise require complex software compensation after installation
2Measurement precision
If software calibration and compensation are implemented, then sensor signal accuracy can be maintained, but processing overhead and setup time increase
Solution Approach 1:
The patent substitutes mechanical adjustment mechanisms for software-based calibration procedures. The mount structure provides physical means to adjust sensor position and orientation during assembly, replacing the need for post-installation software calibration and compensation algorithms, thereby improving installation efficiency while maintaining signal accuracy
3Measurement precision
If precise mechanical adjustment mechanisms are added to the sensor mount, then calibration accuracy improves, but structural complexity and weight increase
Solution Approach 1:
The patent segments the adjustment function into simple, discrete mechanical features integrated into the mount structure. Rather than adding a complex external adjustment mechanism, the mount is designed with built-in positioning features that provide precise adjustment capabilities through simple structural elements, maintaining low complexity while achieving high calibration accuracy

AI summary
A mount for a sensor, comprising: a first mount part for mounting a sensor part; and a second mount part for mounting the first mount part; wherein a first adjustment mechanism is provided to adjust the first mount part relative to the second mount part and a second adjustment mechanism is provided to adjust the second mount part relative to a support; and wherein at least one of the first adjustment mechanism and the second adjustment mechanism is a vernier adjustment mechanism. By providing a mechanical adjustment mechanism the sensor can effectively be calibrated at the time of installation so that all installed sensors are positioned at the correct position and/or orientation. In this way the software calibration and compensation can be avoided as the signal output can be expected to be consistent across devices. The vernier adjustment mechanism allows for particularly accurate positional alignment and/or orientation, thus making accurate mechanical calibration possible. The use of a vernier adjustment mechanism provides sufficiently accurate mechanical adjustment that further electronic or software calibration and compensation is not required, thus simplifying the use of the sensor.
