Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex instruments and equipment are used to measure liquid concentration, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines refractive index measurement and absorbance measurement functions into a single integrated prism device. The prism structure integrates multiple optical paths and measurement capabilities, eliminating the need for separate complex instruments while maintaining measurement precision through combined optical detection
Solution Approach 2:
The patent extracts the essential measurement functions (refractive index and absorbance detection) from complex conventional instruments and implements them in a simplified prism structure. By removing unnecessary components and retaining only the core measurement capabilities, the device achieves accurate liquid concentration measurement with reduced complexity
2Adaptability or versatility
If multiple optical components (lens, eyepiece, filter, polarizer) are used, then measurement capability is improved, but manufacturing cost increases
Solution Approach 1:
The prism is designed as a multi-functional optical component that performs multiple measurement functions simultaneously. The single prism structure provides both refractive index measurement and absorbance measurement capabilities, replacing what would traditionally require multiple specialized components, thereby reducing manufacturing cost while maintaining versatile measurement capability
Solution Approach 2:
The patent uses the prism's geometric structure and optical path design to create simplified optical measurement paths that replicate the functionality of complex multi-component systems. By using the prism's inherent optical properties rather than additional optical components, the design achieves equivalent measurement capability with reduced manufacturing complexity and cost
3Measurement precision
If traditional optical measurement systems are used, then measurement accuracy is maintained, but device volume increases
Solution Approach 1:
The patent embeds multiple measurement functions and optical paths within a compact prism structure. The accommodating space for liquid and the various light transmission surfaces are nested within the single prism body, creating a space-efficient design that maintains measurement accuracy while minimizing device volume
Solution Approach 2:
The patent utilizes three-dimensional optical path routing within the prism structure to achieve compact design. By arranging light transmission surfaces and optical paths in different spatial dimensions and orientations within the prism, the device maintains accurate optical measurement paths while reducing the overall device footprint

AI summary
A prism for measuring liquid concentration includes: an accommodating space for accommodating a liquid; an interface formed on a bottom surface of the accommodating space; a first light transmission surface and a second light transmission surface respectively formed on two side surfaces of the accommodating space; a third light transmission surface and a light emitting surface respectively formed relative to the interface. When a first incident light beam enters the prism, the first incident light beam is reflected to the light emitting surface by the interface, and exits the prism from the light emitting surface. When a second incident light beam enters the prism to the first light transmission surface, the second incident light beam exits the prism to the accommodating space from the second incident light beam, passes through the liquid and the second light to the prism, and exits the prism from the third light transmission surface.
