Rotatable Sensor Carrier Module for Adjustable Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor modules have limited adjustability of the sensor field of view, making them less versatile for different installation scenarios.
Innovation Solution
A sensor module with a sensor carrier and housing featuring coaxial cylindrical holders allowing the sensor carrier to rotate, enabling adjustable angular positioning through a force-fitting or form-fitting connection, which can be set and secured during assembly, allowing the sensor field of view to be adjusted over a wide range (e.g., more than 90°, 120°, or 180°).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sensor carrier is fixed rigidly in the housing, then the structural stability is improved, but the adaptability to different installation scenarios deteriorates
Solution Approach 1:
The sensor carrier is designed to be rotatable relative to the housing around a rotation axis, transforming the fixed rigid connection into a dynamic adjustable connection. This allows the sensor field of view to be oriented in different directions while maintaining structural stability through the defined rotation axis and mounting holders.
2Adaptability or versatility
If the sensor carrier is made adjustable over a wide range, then the adaptability to different installation scenarios is improved, but the device complexity increases
Solution Approach 1:
The housing is divided into a first holder and a second holder that are arranged coaxially and support the sensor carrier at different locations. This segmentation allows the complex adjustment function to be distributed across simple structural elements, reducing overall device complexity while maintaining wide adjustability.
Solution Approach 2:
The rotation mechanism serves multiple functions: it allows adjustment of the sensor field of view orientation, provides mechanical support through the holders, and enables adaptation to different installation scenarios. This multi-functionality reduces the need for separate adjustment mechanisms, thereby reducing device complexity.
3Ease of operation
If the sensor carrier is made rotatable, then the ease of operation for adjusting field of view is improved, but the reliability under vibrations deteriorates
Solution Approach 1:
The sensor carrier is adjusted to the desired angular position before final assembly, and then fixed in place using a locking mechanism or adhesive applied during the assembly process. This preliminary adjustment followed by securing ensures ease of operation during setup while maintaining reliability during operation under vibrations.

AI summary
A sensor module includes: a sensor carrier for accommodating a sensor; and a housing having two coaxial cylindrical holders in which cylindrical ends of the sensor carrier are mounted to rotate around an axis. The sensor module fixes the sensor carrier in an adjustable angular position relative to the housing by producing a force-fitting or form-fitting connection between the housing and an outer surface region of the sensor carrier.
