Two-Sided Applicator with Rotatable Dispensers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applicator devices do not efficiently provide simultaneous access to lip balm and sunscreen, limiting user convenience for applying both products simultaneously.
Innovation Solution
A two-sided applicator device featuring a first tube for lip balm and a second tube for sunscreen, each with a rotatable dispenser and a pliable cylinder, allowing for simultaneous application by rotating the dispensers to extend or retract the cylinders, with a clip for easy attachment to clothing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single applicator device provides both lip balm and sunscreen, then user convenience and access to both products is improved, but device complexity increases
Solution Approach 1:
The applicator device is segmented into two independent dispensers (first dispenser for lip balm, second dispenser for sunscreen), each with its own tube, cylinder, and dispensing mechanism. This segmentation allows each component to function independently while being integrated into a single device, providing user convenience without excessive complexity.
Solution Approach 2:
The applicator device is designed as a multi-functional unit that combines lip balm application and sunscreen application capabilities in one device. The universal design allows users to access both products simultaneously through a single device, improving ease of operation while managing complexity through integrated design.
2Device complexity
If two separate applicator devices are used for lip balm and sunscreen, then device complexity is reduced, but user convenience and simultaneous access is worsened
Solution Approach 1:
Two separate applicator functions are merged into a single integrated device. The first tube and second tube are positioned side-by-side with their respective dispensers, allowing users to access both lip balm and sunscreen from one device rather than carrying two separate devices, thereby improving user convenience.
Solution Approach 2:
The device utilizes a side-by-side spatial arrangement of the two tubes and dispensers, effectively using horizontal space to accommodate both functions. This dimensional organization allows both products to be accessible simultaneously without significantly increasing overall device complexity.
3Ease of operation
If the cylinders are made pliable for easy application, then ease of operation is improved, but structural stability deteriorates
Solution Approach 1:
The cylinders are constructed from pliable material that allows them to be easily manipulated and applied to the skin. The flexible nature of the cylinders enables easy application while the containment within protective tubes maintains structural stability during storage and transport.
Solution Approach 2:
The cylinders are designed to transition between a retracted stable state (within the tube) and an extended application state (outside the tube). The pliable material allows dynamic deformation during application while the tube provides structural stability when not in use, balancing both requirements.

AI summary
A two-sided applicator assembly includes a first tube and a second tube. A first dispenser is rotatably coupled to the first tube and a second dispenser is rotatably coupled to the second tube. Moreover, the first dispenser is coupled to the second dispenser such that the first tube is directed in an opposite direction from the second tube. A first cylinder is movably coupled to the first dispenser and the first cylinder is comprised of a pliable material. The first cylinder is infused with a chemical lip balm for applying the chemical lip balm to lips. A second cylinder is movably coupled to the second dispenser and the second cylinder is comprised of a pliable material. The second cylinder is infused with a chemical sunscreen for applying the chemical sunscreen to skin.
