Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening units for sensors lack sufficient torque rigidity, particularly in intermediate joints, leading to instability and potential unintentional adjustments due to external factors.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening units are used to attach sensors to mounting rods, then the sensors can be installed at the required positions, but the torque rigidity is insufficient leading to instability and unintentional adjustments
Solution Approach 1:
The fastening unit is divided into separate components: a fastening element with toothing for form-fit connection, a clamp holder for frictional locking, and optional adapters. This segmentation allows each component to specialize in providing specific mechanical properties (form-fit stability + frictional holding force) that together resolve the torque rigidity issue.
Solution Approach 2:
The fastening unit combines different connection mechanisms (form-fit toothing connection and frictional non-positive connection) into a composite fastening system. This composite approach integrates both rigid positioning (from toothing) and secure holding (from friction), achieving the required torque rigidity and stability.
2Strength
If the fastening unit uses a form-fit connection with toothing, then torque rigidity increases, but the toothing may be visible and susceptible to contamination
Solution Approach 1:
The toothing is extracted from the outer surface and integrated into the internal structure of the fastening element. The toothing engages with corresponding features inside the clamp holder or mounting rod, removing it from external exposure while maintaining its torque-rigidity-providing function.
Solution Approach 2:
The toothing mechanism is nested within the fastening unit structure, with the fastening element containing toothing that engages with internal features of the clamp holder or mounting rod. This nesting conceals the toothing from external view and protects it from contamination while preserving its mechanical function.
3Stability of the object's composition
If a non-positive frictional locking mechanism is used, then the mounting rod is secured without notches or deformations, but the torque rigidity may be insufficient
Solution Approach 1:
The invention merges two connection mechanisms: form-fit toothing connection (for torque rigidity) and non-positive frictional connection (for securing the rod without deformations). The fastening element with toothing provides rigid positioning, while the clamp holder applies frictional force to secure the rod, and their combination resolves both requirements simultaneously.

AI summary
The invention relates to a fastening unit for attaching a sensor to a mounting body or system. In a particularly rotationally rigid fastening unit, the fastening unit consists of two disc-like fastening elements (1, 2) which are positively connected to each other via a toothed connection (3, 4, 62, 64), wherein the toothed connection is integrated into at least one of the fastening units (1, 2), is directly in mutual engagement and generates the positive locking, and the first fastening element (1) has a continuous opening (5) axially for encircling a mounting rod (6), wherein the opening (5) transitions into a gap (7) which partially separates the fastening element (1) radially to the outside.
