Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an applicator wand is attached to the bottle cap and dipped into the lip gloss material, then the lip gloss can be applied to the lips, but the amount of lip gloss applied varies each time leading to user discomfort and poor make-up results
Solution Approach 1:
The patent replaces the traditional dipping mechanical system with a pump-based dispensing system. The pump mechanism (comprising a piston, cylinder, and valve) substitutes the manual dipping action, providing controlled extrusion of lip gloss through mechanical actuation. This allows precise control over the amount of lip gloss dispensed with each pump action, eliminating the variability inherent in the dipping method.
Solution Approach 2:
The patent changes the operational parameter from variable dipping depth to fixed pump stroke volume. By designing the pump chamber with specific dimensions and the piston with a defined stroke length, the volume of lip gloss dispensed is standardized. This parameter control ensures consistent application amount with each pump action, directly addressing the measurement precision issue.
2Duration of action of moving object
If the applicator wand is repeatedly dipped into the lip gloss material during use, then the lip gloss can be continuously applied, but the lip gloss material is exposed to air causing rapid deterioration
Solution Approach 1:
The patent extracts the lip gloss material from direct air exposure by implementing a sealed reservoir system. The lip gloss is stored in a closed chamber that only opens during controlled dispensing through the pump mechanism. This extraction of the material from the harmful air environment during non-use periods prevents oxidation and deterioration, maintaining material stability while enabling continuous application over time.
Solution Approach 2:
The pump mechanism serves as an intermediary between the sealed lip gloss reservoir and the applicator. Instead of direct air contact, the pump acts as a mediator that transfers the lip gloss from the sealed storage to the applicator head through controlled mechanical action. This intermediary system maintains the seal integrity while enabling repeated dispensing operations.
3Quantity of substance
If various structural designs for lip gloss pens are used, then some can contain liquid make-up dyes, but overflow occurs when carried reducing portability
Solution Approach 1:
The patent implements a nested structure where the applicator components are housed within the pump mechanism, which in turn is contained within the sealed reservoir. The pump cylinder and piston are nested within the reservoir chamber, and the applicator head is integrated into the pump assembly. This nested arrangement compactly contains all liquid-holding components within the portable pen body, preventing overflow while maintaining adequate capacity.
Solution Approach 2:
The patent employs a dynamic sealing system with movable components. The piston moves within the cylinder to dispense lip gloss, and the valve mechanism dynamically opens and closes to control flow. This dynamic design allows the structure to adapt during use (enabling dispensing) while maintaining a sealed, compact form during carrying, thus resolving the portability-overflow contradiction.

Function Achieved in This Case
Enables precise control of cosmetic application, prevents overflow, and ensures ease of use and portability by sealing the container.
Implementation Method 1
the push block is operable to strike the inner stopper to compress space of the storage chamber, and the cosmetic liquid is operable to be flown out from the applicator through the open head portion

AI summary
The present utility model discloses a cosmetic container, comprising a cap assembly, a base assembly, a connecting rod, an inner stopper, a push block, an open head portion, and an applicator; wherein the cap assembly is configured to be rotatably connected to the base assembly to cover an opening of the base assembly, one end of the connecting rod is configured to be fixedly arranged at a bottom of the base assembly, and the other end of the connecting rod is configured to be fixedly connected to the open head portion; the applicator is configured to be fixedly arranged on and fluidly connected to the open head portion, and the inner stopper is configured to be movably arranged on the connecting rod; a circumferential side of the inner stopper is configured to be pressed against an inner wall of the base assembly, and a lower end surface of the inner stopper and the base assembly are configured to form a movable chamber; the push block is configured to be movably arranged within the movable chamber, and an upper end surface of the inner stopper, the open head portion, and the base assembly are configured to form a storage chamber for storing cosmetic liquid. During use, the user only needs to shake the base assembly of the utility model to strike the inner stopper to cause it move toward the open head portion. This, in turn, compresses the space of the storage chamber, allowing the cosmetic liquid to flow from the first through hole to the second through hole via the slit. The present utility model promotes precise control of the amount of cosmetic liquid extruded, thus facilitating ease of use and simplicity in structure.
