Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate gages are used for dimensional accuracy measurement and leak tightness testing, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines dimensional accuracy measurement and leak tightness testing into a single integrated test device. The gage includes both optical measurement systems for dimensional checking and leak detection systems, allowing both measurements to be performed simultaneously on the same component setup, thereby reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The test device is designed with multi-functionality to perform both dimensional accuracy measurement and leak tightness testing using a single gage structure. The universal design allows the same device to accommodate different measurement tasks through configurable measurement systems, eliminating the need for separate specialized gages for each function.
2Measurement precision
If separate steps for dimensional accuracy measurement and leak tightness testing are performed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent merges dimensional accuracy measurement and leak tightness testing into a single simultaneous operation. The integrated gage allows both measurements to be conducted in one testing step rather than requiring sequential steps, thereby significantly reducing the total testing time while maintaining the precision requirements of both measurement types.
Solution Approach 2:
The test device enables continuous measurement by performing both dimensional accuracy checking and leak tightness testing simultaneously during the same operational cycle. This continuous approach eliminates idle time between separate testing steps and allows both measurements to be completed in parallel, reducing overall testing duration.
3Measurement precision
If individually produced gages are used for each component, then measurement precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent implements a universal gage design that can measure both dimensional accuracy and leak tightness across different component types. This standardized multi-functional gage replaces the need for individually produced custom gages for each component, significantly improving ease of manufacture while maintaining measurement precision through configurable measurement systems.

AI summary
A test device including two measuring systems is provided. The test device includes a first measuring system which is configured for leakage testing of a test object, and a second measuring system which is configured for dimensional checking of the test object. The first measuring system has at least one connecting region, by which a test medium can be introduced into the test object. The test object can be set into rotation via the at least one connection region, on which the dimensional checking is based.
