Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed measuring device is used with precise alignment, then measurement precision is improved, but adaptability deteriorates
Solution Approach 1:
The measuring device transitions from a fixed installation to a mobile, reversibly mountable system. The holding body can be attached and detached from vessels, and the light source and receiving device can adjust their positions dynamically while maintaining the required optical alignment through the defined geometric relationship on the holding body surface.
2Adaptability or versatility
If a mobile measuring device is used, then adaptability is improved, but measurement precision deteriorates
Solution Approach 1:
The invention changes the parameter of spatial relationship from absolute fixed coordinates to a relative geometric invariant. The angle defined by three points (light source position, receiving device position, and mounting section position) remains constant regardless of the device's location or orientation, ensuring measurement precision is maintained while enabling mobile operation.
3Measurement precision
If precise alignment is maintained in reversible mounting, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The holding body structure itself provides the alignment function through its geometric design. The defined positions of the light source, receiving device, and mounting section create an inherent angular relationship that automatically ensures correct optical alignment when the device is mounted, eliminating the need for additional complex alignment mechanisms or adjustment devices.

Implementation Method 3
The holding body (40) is equipped with a mounting section (42) for mounting the vessel (100) in a defined position. Furthermore, the light source (20) is arranged on the holding body (40) in a defined source position (QP) relative to the mounting section (42), and the receiving device (30) is also arranged on the holding body (40) in a defined receiving position (EP) relative to the mounting section (42). This results in a defined angle of incidence forming between the receiving direction (ERE) and the light output direction (LAR)
