Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Calibration appliances for optical measuring instruments are prone to damage, soiling, and aging, leading to reduced durability and reliability.
Innovation Solution
A calibration body with scattering elements embedded within a glass body, protected from external damage and soiling, is used, where the scattering elements are created through laser treatment and fixed internally, ensuring they are not susceptible to mechanical influences or aging processes, and the calibration body is securely fastened to a carrier for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If calibration bodies are made accessible on the surface for calibration purposes, then calibration functionality is enabled, but the scattering elements become susceptible to damage, soiling, and ageing
Solution Approach 1:
The scattering elements are nested within the glass body, specifically embedded in the interior space of the glass calibration body. This nesting protects the scattering elements from external damage and soiling while maintaining their optical functionality for calibration purposes.
Solution Approach 2:
The glass body acts as an intermediary medium that contains the scattering elements internally. The glass body provides a protective barrier between the scattering elements and the external environment, allowing calibration functionality while preventing direct exposure to harmful factors.
2Ease of repair
If calibration appliances are subjected to rough handling and cleaning processes, then ease of maintenance is improved, but the calibration bodies become soiled and damaged
Solution Approach 1:
The scattering elements are nested within the glass body, making them inaccessible to cleaning agents and external contaminants. This eliminates the need for direct cleaning of the scattering elements themselves while maintaining the calibration functionality through the protected internal structure.
Solution Approach 2:
The glass body surface can be cleaned and replaced if necessary, while the valuable scattering elements remain protected internally. This allows the external protective layer to be sacrificed or maintained separately from the core functional elements.
3Ease of operation
If scattering elements are placed on the surface of the calibration body, then calibration functionality is achieved, but the elements are susceptible to mechanical influences and ageing processes
Solution Approach 1:
The scattering elements are nested within the interior of the glass body rather than being placed on the surface. This internal positioning protects them from mechanical influences and ageing processes while maintaining their optical scattering functionality for calibration.
Solution Approach 2:
The glass body provides beforehand cushioning and protection to the scattering elements by enclosing them internally. This protective enclosure is established in advance to prevent exposure to harmful environmental factors throughout the service life of the calibration body.
4Manufacturing precision
If the calibration body is securely fastened to the carrier, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The mounting structure integrates the fastening function directly into the carrier design, combining the holding and positioning functions in a unified structure. This reduces overall device complexity while achieving secure fastening and precise positioning of the calibration body.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the resistance and durability of calibration appliances, ensuring reliable and reproducible measurement values by protecting the scattering elements from damage and soiling, and maintaining their functionality over time.
Implementation Method 1
this scattering element being completely surrounded by the glass body and a degree of transmission of the scattering element and of another region of the glass body differing from each other
Implementation Method 2
these scattering elements are produced with the aid of methods known from the prior art in the interior of the glass body, for example by a local melting of the glass material being carried out in the interior. This can be carried out for example by a so-called 3D laser engraving
