Innovation Solution
Incorporating a liquid alginate, water, an oily component, and/or a lipid component at normal temperature into the base material paste to maintain viscosity and improve storage stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alginate base material paste is used, then the material can be stored for use, but the viscosity decreases over time leading to poor storage stability
Solution Approach 1:
The patent changes the chemical composition parameters of the base material paste by adding specific components (amino acid, peptide, or protein) to control and stabilize viscosity over time. This compositional modification prevents the harmful viscosity decrease that occurs in conventional formulations during storage.
Solution Approach 2:
The patent creates a composite base material paste by combining alginate with amino acids, peptides, or proteins. This composite formulation leverages the interaction between these components to maintain stable viscosity characteristics, resolving the contradiction between storability and viscosity stability.
2Duration of action of stationary object
If the base material paste is stored over time, then it remains available for use, but viscosity reduction occurs compromising impression accuracy
Solution Approach 1:
The patent applies preliminary action by incorporating viscosity-stabilizing components (amino acid, peptide, or protein) into the base material paste during manufacturing. This pre-prepared formulation ensures that when the material is stored and later used, the viscosity remains stable, thereby maintaining impression accuracy throughout the storage period.
Solution Approach 2:
By modifying the chemical composition to include amino acids, peptides, or proteins, the patent changes the rheological parameters of the paste. This parameter change ensures that viscosity remains within acceptable ranges for accurate impression-taking even after extended storage periods.
