Makeup Case with Semi-Circular Friction Holder for Paired Cosmetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current makeup storage systems fail to conveniently and elegantly keep paired cosmetics, such as lipsticks and lip liners, together, leading to frustration and delays in makeup application due to disorganization and separation during use.
Innovation Solution
A lipstick case with a semi-circular holder on its exterior surface that frictionally secures a pencil, such as a lip liner or eyeliner, allowing easy insertion and removal without needing to remove the cover, using a dual-durometer material for flexibility and grip, accommodating various pencil sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If makeup is stored in a makeup bag or case with multiple similar items, then storage capacity is improved, but organization and identification of paired makeup items deteriorates
Solution Approach 1:
The holder is segmented into multiple compartments, each designed to hold specific paired makeup items together. This segmentation allows the makeup case to accommodate multiple pairs of lipstick and lip liner while keeping each pair organized and easily identifiable through color-matched compartments.
2Adaptability or versatility
If paired lipstick and lip liner are placed in a purse with other objects, then portability is improved, but the risk of separation and loss increases
Solution Approach 1:
The holder merges the storage of lipstick and lip liner into a single integrated unit. The lip liner is held in a compartment that is physically connected to the lipstick compartment, ensuring that both items remain together as a complete pair when carried in a purse or bag.
3Reliability
If a holder design is made secure to prevent removal, then reliability is improved, but ease of insertion and removal deteriorates
Solution Approach 1:
The holder employs a dynamic friction-based retention system rather than a fixed mechanical lock. The lip liner is held in place by friction between the holder walls and the lip liner body, which provides secure holding during normal use but allows easy removal when sufficient force is applied to overcome the friction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively keeps paired makeups together, preventing separation and re-pairing errors, saving time and reducing frustration, while being easy to use and durable, with a robust design suitable for various makeup combinations.
Implementation Method 1
The pencil is inserted into the holder by providing sufficient force to deflect the opposing lips thereby allowing the pencil to reside within the semi-circular holder while being frictionally held therein.

AI summary
A makeup case system is presented that helps to keep two paired makeups together. As one example, a lipstick case is presented having a cover and a base. A holder is positioned in an exterior surface of the lipstick case, that when viewed from above or below is semi-circular in shape. The holder is sized and shaped to receive a pencil, such as a lip liner pencil or eyeliner pencil or brush, therein. The holder includes lips that extend past a centerline or maximum diameter of the pencil. A pencil is inserted into the holder by providing sufficient force to deflect the opposing lips thereby allowing the pencil to reside within the semi-circular holder while being frictionally held therein. The pencil is similarly removed by providing sufficient force to overcome this frictional engagement thereby allowing the pencil to be removed from the holder.
