Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional chemical coloring products are used to detect microbial films, then the microbial film can be visualized, but residual substances remain on the tooth surface causing poor aesthetics and requiring physical scraping
Solution Approach 1:
The patent changes the chemical parameters of the coloring agent by using riboflavin 5-phosphate sodium, a water-soluble vitamin that fluoresces under specific light conditions. This parameter change allows the agent to be washed away easily after serving its detection function, eliminating residual substances while maintaining detection capability.
Solution Approach 2:
The patent employs a disposable coloring agent that performs its function and then is completely removed. The riboflavin 5-phosphate sodium acts as a short-lived marker that fluoresces during detection and then dissipates without leaving residues, unlike conventional long-lasting dental dyes that require scraping removal.
2Measurement precision
If conventional optical devices are used to observe microbial films, then the film can be detected, but early-stage films cannot be observed and the method is not aesthetically pleasing
Solution Approach 1:
The patent utilizes color changes through fluorescence emission. The riboflavin 5-phosphate sodium remains colorless in normal light but emits bright fluorescence under specific light conditions, allowing early-stage microbial films to be clearly visualized against the tooth surface without affecting aesthetics during normal use.
Solution Approach 2:
The patent introduces an intermediary substance (riboflavin 5-phosphate sodium) that mediates between the microbial film and the detection method. This intermediary binds to the microbial film and provides a visible signal only when needed, allowing early detection without requiring complex optical devices or compromising aesthetics.
3Measurement precision
If chemical coloring products are applied to detect microbial films, then the film becomes visible, but the aesthetics are poor due to residual material remaining on teeth
Solution Approach 1:
The patent changes the physical and chemical parameters of the coloring agent to be water-soluble and fluorescent rather than persistent and opaque. This parameter change allows the agent to be easily removed by rinsing while maintaining excellent aesthetics during and after use.
Solution Approach 2:
The patent replaces the mechanical removal method (scraping) with a chemical dissolution approach. The water-soluble nature of riboflavin 5-phosphate sodium allows it to be removed through simple rinsing with water, eliminating the need for mechanical scraping and improving patient comfort and aesthetics.
