Problem
Current cuvettes for photometric measurements are costly, require complex repairs, and involve high maintenance, making water analysis cumbersome and expensive, as users need to carry separate cuvettes and photometers.
Innovation Solution
A cuvette integrated with a photometer, where the photometer is mounted or printed directly on the cuvette, allowing for compact, cost-efficient, and easy-to-maintain photometric measurements, with the option of a transmitting unit for wireless data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate photometer is used for photometric measurements, then measurement precision is improved, but device complexity increases and maintenance costs increase
Solution Approach 1:
The patent integrates the photometer directly into the cuvette structure, combining two previously separate devices (cuvette and photometer) into a single integrated unit. This merging eliminates the need for separate carrying and operation of two devices, reduces overall system complexity, and maintains measurement precision through the photometer's direct integration with the sample container.
2Measurement precision
If a separate photometer is used for photometric measurements, then measurement precision is improved, but maintenance costs increase
Solution Approach 1:
By integrating the photometer into the cuvette as a single unit, the patent simplifies maintenance operations. Users no longer need to service two separate devices, reducing overall maintenance frequency and costs. The compact integrated design allows for easier handling and reduces the complexity of repair procedures.
3Measurement precision
If a separate photometer is used for photometric measurements, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The integration of the photometer into the cuvette creates a single-handheld device that combines sample holding and measurement functions. Users no longer need to coordinate two separate devices during measurement, simplifying the operational workflow and improving ease of use while maintaining accurate photometric measurements.
4Ease of operation
If an integrated photometer-cuvette device is created, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs modular design principles where the photometer and cuvette components can be manufactured separately with standard precision requirements, then assembled into the integrated device. This segmentation allows each component to be produced using conventional manufacturing processes, reducing the overall manufacturing precision burden while achieving the integrated functionality.
