Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high viscosity paste type toothpaste is used to effectively deliver drug to teeth and gums, then cleaning effectiveness is improved, but discharge difficulty increases and piston wear occurs due to abrasive hardness exceeding pump material hardness
Solution Approach 1:
The patent modifies the physical and chemical parameters of the toothpaste composition by controlling viscosity within 50-5000 cP, adjusting solid content to 10-60%, and regulating abrasive particle size to 1-50 μm. These parameter optimizations enable the toothpaste to maintain effective cleaning properties while ensuring smooth pump discharge and reducing piston wear.
Solution Approach 2:
The patent employs composite material design by combining multiple ingredients including binders (cellulose derivatives, proteins), lubricants (polyethylene glycol, mineral oil), and abrasives (silica, calcium carbonate) in specific proportions. This composite formulation achieves balanced rheological properties that facilitate both effective cleaning and easy discharge from the pump system.
2Reliability
If high viscosity paste type toothpaste is used to improve spreading property, then cleaning performance is enhanced, but discharge stability deteriorates over time and product hardening occurs
Solution Approach 1:
The patent optimizes viscosity parameters to remain within 50-5000 cP range and controls solid content between 10-60%, preventing the composition from hardening over time. These parameter controls ensure both effective cleaning performance and stable discharge characteristics throughout the product shelf life.
Solution Approach 2:
The patent incorporates lubricants such as polyethylene glycol and mineral oil that continuously reduce friction between abrasive particles and the pump piston, maintaining discharge stability over time. The binder system also continuously maintains composition homogeneity, preventing separation and hardening during storage and use.
3Reliability
If abrasive content is increased to improve cleaning effectiveness, then plaque removal is enhanced, but piston wear increases due to abrasive hardness exceeding pump material hardness
Solution Approach 1:
The patent controls abrasive particle size within 1-50 μm and adjusts abrasive content to 10-60% of total composition. This parameter optimization maintains effective plaque removal while minimizing mechanical wear on the pump piston by reducing the severity of abrasive contact.
Solution Approach 2:
The patent introduces lubricant ingredients (polyethylene glycol, mineral oil) that act as intermediary substances between the abrasive particles and the pump piston. These lubricants form protective films that reduce direct abrasive contact with the piston surface, thereby minimizing wear while preserving cleaning effectiveness.
4Ease of operation
If liquid toothpaste with good flowing property is used to improve ease of discharge, then pump operation is facilitated, but cleaning effectiveness decreases due to insufficient cleaning ingredients
Solution Approach 1:
The patent optimizes viscosity to 50-5000 cP and solid content to 10-60%, creating a formulation that flows sufficiently for easy pump discharge while maintaining adequate concentration of cleaning ingredients. This parameter balance ensures both operational ease and effective cleaning performance.
Solution Approach 2:
The patent formulates a composite toothpaste containing multiple cleaning agents (abrasives, binders, lubricants) in optimized proportions. This composite structure provides sufficient cleaning ingredients for effective plaque removal while maintaining appropriate flow characteristics for smooth pump operation and discharge.

AI summary
The present disclosure relates to a pump-type toothpaste composition capable of being provided as contained in a pumping type container, and to a pump-type toothpaste composition improving the spreading property to a tooth as the toothpaste composition discharged to a toothbrush penetrates into the toothbrush and having an effect of ultimately delivering a medicinal ingredient continuously for a long time in the oral cavity.In addition, the present disclosure relates to a pump-type toothpaste composition with excellent commercial value, which can ensure discharge stability without hardening and accordingly, can be used in a pump-type container equipped with a dispenser pump (dip pump), which has a remarkable problem of hardening in the discharge port due to free movement of external air because of properties of the container, and thus can ensure even the convenient use.
