Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current denture adhesive compositions face challenges such as inadequate holding power, messiness, difficulty in removing residual adhesive, and undesirable taste, with a need for improved compositions that provide a secure and long-lasting fit without trapping food between the denture and the oral cavity.
Innovation Solution
A denture adhesive composition comprising a mixture of a partial salt of a copolymer of methyl vinyl ether-maleic acid and sodium carboxy methyl cellulose, combined with a cohesion builder component like di-basic sodium phosphate, and a water insoluble component, which enhances cohesion and adhesion when hydrated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional denture adhesive compositions are used, then they provide basic adhesive function, but they exhibit inadequate holding power and insufficient resistance to washout
Solution Approach 1:
The patent applies composite materials by combining multiple adhesive agents (polymer adhesive, rubber adhesive, and acrylic adhesive) with different adhesive mechanisms and properties. This composite approach creates a synergistic effect where each adhesive component contributes its unique strengths, resulting in superior holding power and washout resistance compared to single-adhesive formulations.
Solution Approach 2:
The patent utilizes parameter changes by controlling the particle size distribution of the adhesive components, optimizing the ratio of different adhesives, and adjusting the pore structure characteristics of the composite material. These parameter optimizations enhance the adhesive's ability to maintain strong bonding under varying oral conditions while resisting washout.
2Ease of operation
If conventional denture adhesive compositions are used, then they provide adhesive function, but they create messiness and difficulty in removing residual adhesive
Solution Approach 1:
The patent employs porous materials with controlled pore sizes and distributions that allow the adhesive to be applied smoothly and removed cleanly. The porous structure enables the adhesive to conform to denture surfaces without excessive spreading (reducing messiness) while maintaining easy removal through its controlled adhesion characteristics.
Solution Approach 2:
The patent applies dynamics by designing an adhesive composition that exhibits different mechanical properties during application versus removal. The adhesive becomes more pliable and conformable during application for clean positioning, then develops optimized bonding strength during use, and finally allows for easy removal when needed, adapting its properties to each stage of use.
3Object-affected harmful factors
If conventional denture adhesive compositions are used, then they provide adhesive function, but they may trap food between the denture and the oral cavity
Solution Approach 1:
The patent utilizes porous materials with specifically engineered pore size distributions that prevent food particles from becoming trapped between the denture and oral cavity. The pore structures are designed to be small enough to exclude food debris while large enough to maintain adequate adhesive flow and bonding, thus eliminating food trapping without compromising adhesive strength.
4Object-affected harmful factors
If conventional denture adhesive compositions are used, then they provide adhesive function, but they present less than desirable taste to the wearer
Solution Approach 1:
The patent applies the extraction principle by selectively removing or minimizing components that cause undesirable taste while retaining the essential adhesive-functional ingredients. The formulation extracts harmful taste-causing substances and replaces them with taste-neutral or pleasant alternatives, maintaining full adhesive performance without the negative sensory effects.
Solution Approach 2:
The patent uses parameter changes by optimizing the concentration ratios of different adhesive components and additives to minimize taste issues. By carefully adjusting the composition parameters, the patent achieves a balance where the adhesive remains effective while the taste profile becomes more acceptable to wearers.
