Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a turntable is incorporated to enable sequential measurement of multiple measurement objects, then the measurement capability is improved, but the apparatus size and footprint increase
Solution Approach 1:
The measurement system is segmented into a fixed measurement unit and a movable sample carrier. Instead of rotating the entire apparatus, only the sample carrier moves to position different samples under the fixed measurement optical system, reducing the required footprint area while maintaining multi-sample measurement capability
Solution Approach 2:
The patent transitions from a planar turntable rotation to a three-dimensional positioning system where the sample carrier moves along multiple axes (X, Y, Z directions) to bring different samples into the measurement position, thereby reducing the horizontal footprint while preserving measurement versatility
2Adaptability or versatility
If a turntable is incorporated to enable sequential measurement of multiple measurement objects, then the measurement capability is improved, but the device complexity and production costs increase
Solution Approach 1:
The complex turntable mechanism is extracted and replaced with a simpler movable sample carrier that can be actuated by basic driving means such as linear actuators or motors, significantly reducing the number of components and simplifying the overall device structure while maintaining the ability to sequentially measure multiple samples
Solution Approach 2:
The fixed measurement optical system serves as a universal measurement unit that can measure different types of samples (liquid, solid, gas) by simply changing the sample carrier or sample container, eliminating the need for multiple specialized measurement systems and reducing device complexity
3Adaptability or versatility
If different measurement object holding members are prepared for different types of measurement objects, then the measurement versatility is improved, but the device complexity and user burden increase
Solution Approach 1:
The sample carrier is designed as a dynamic, replaceable component that can be easily swapped or reconfigured depending on the sample type. This dynamic adaptability allows the system to handle different measurement objects (liquids in cuvettes, solids on stages, gases in chambers) without requiring permanently installed specialized holders, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The measurement system can adapt to different sample types by changing parameters such as the sample carrier configuration, measurement wavelength, or measurement mode rather than requiring physically different measurement systems. This parameter-based adaptability reduces the need for multiple specialized components

AI summary
An optical measurement apparatus (1, 201, 301) includes a main body base (10), an optical base (11) movably combined with the main body base (10), a measurement optical system (30) fixed to the optical base (11), and an optical base moving mechanism (21)which moves the optical base (11) relative to the main body base (10). The optical base moving mechanism (21) moves the optical base (11) relative to the main body base (10) between an internal measurement position (11A) and an external measurement position (11B). At the internal measurement position (11A), a measurement object position (30a) of the measurement optical system (30) coincides with an internal measurement object position (30A) within the main body base (10). At the external measurement position (11B), a measurement object position (30a) of the measurement optical system (30) coincides with an external measurement object position (30B) outside the main body base (10).
