Solution Overview
Problem
Existing sensor mounting technologies face challenges in achieving secure, exact, and reproducible attachment, requiring additional work and precision due to the reliance on positioning pins and complex alignment procedures, which complicates the exchange and positioning of sensors.
Innovation Solution
A mounting unit with reference surfaces arranged in different planes and at acute angles, combined with a conical fastening screw and optional grub screw, ensures precise and reproducible positioning of sensors, allowing for easy installation and removal, and enhanced mechanical stability through symmetrical and wedge-shaped configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning pins are used to achieve accurate sensor positioning, then positioning precision is improved, but manufacturing complexity and additional work are increased
Solution Approach 1:
The patent removes positioning pins from the mounting structure and replaces them with integrated reference surfaces on the housing. This extraction eliminates the need for separate positioning components while maintaining positioning accuracy through precisely machined reference surfaces that directly guide sensor placement.
Solution Approach 2:
The reference surfaces are integrated directly into the housing structure, merging the positioning function with the housing itself. This consolidation eliminates separate positioning pins and reduces the number of components, thereby decreasing manufacturing complexity while preserving positioning precision.
2Reliability
If complex alignment procedures are used to ensure secure attachment, then attachment reliability is improved, but ease of operation is worsened
Solution Approach 1:
The reference surfaces are designed to automatically guide the sensor into the correct position during installation. The sensor's mounting features naturally align with the reference surfaces without requiring external alignment tools or complex procedures, enabling the system to self-align and simplify the attachment operation.
Solution Approach 2:
The reference surfaces are pre-machined into the housing with precise geometries that encode the correct sensor position and orientation. This preliminary preparation of alignment features eliminates the need for complex alignment procedures during sensor installation, as the geometry itself guides proper placement.
3Measurement precision
If multiple reference surfaces in different planes are used, then positioning accuracy is improved, but device complexity is increased
Solution Approach 1:
Multiple reference surfaces are integrated directly into the housing structure rather than being separate components. This merging of reference surfaces with the housing eliminates the need for additional positioning fixtures or attachments, reducing device complexity while maintaining the benefits of multi-plane reference geometry for enhanced positioning accuracy.
