Cosmetic Applicator Barrel Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators with heavy parts at the rear to balance the center of gravity are prone to damage and leakage when dropped, as the increased mass puts stress on the barrel, potentially causing it to break and leak cosmetic liquid.
Innovation Solution
Incorporating a resilient member, such as a double-wound metal spring, at the rear of the barrel cylinder to absorb shock and distribute the weight, thereby reducing the risk of damage and leakage during drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy parts are arranged in the rear part of the barrel cylinder to place the center of gravity on the rear side, then the applicator can be easily oriented upward during application, but the rear portion of the barrel is damaged when the applicator is dropped due to increased mass
Solution Approach 1:
A resilient member (spring) is installed in the rear portion of the barrel cylinder before use. When the applicator is dropped, this pre-positioned resilient member absorbs the impact shock, preventing damage to the barrel and cosmetic liquid. This resolves the contradiction by cushioning against the harmful effects of the heavy rear design during drops while maintaining the center of gravity positioning for easy orientation during normal use.
2Ease of operation
If heavy parts are arranged in the rear part of the barrel cylinder to place the center of gravity on the rear side, then the applying part can be easily oriented upward during application, but the cosmetic liquid stored in the barrel may leak out due to breakage
Solution Approach 1:
The resilient member is installed in advance in the rear portion of the barrel to absorb impact shocks before they can cause breakage and leakage. This protective measure ensures that the cosmetic liquid remains contained even when the applicator is dropped, resolving the reliability issue while preserving the ease of orientation benefit from the rear-weighted design.
3Ease of operation
If the mass of the applicator is increased by arranging heavy parts in the rear part, then the center of gravity is placed on the rear side for easy orientation, but the shock on the barrel cylinder increases when the applicator is dropped
Solution Approach 1:
The resilient member (spring) is pre-installed in the rear portion of the barrel cylinder to absorb impact forces during drops. This cushioning mechanism reduces the shock force transmitted to the barrel structure while allowing the applicator to maintain its rear-weighted design for easy orientation during normal use, thus resolving the contradiction between operational ease and shock reduction.
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 resilient member effectively absorbs shock and distributes weight, enhancing the cosmetic applicator's durability and preventing leakage by maintaining the center of gravity while reducing the risk of barrel damage, thus improving the applicator's functionality and user safety.
Implementation Method 1
provision of a resilient member on the rear side of the barrel cylinder enables the resilient member to absorb the shock acting on the applicator when it is dropped

AI summary
Provided a cosmetic applicator that can alleviate the shock at its barrel cylinder even if the center of gravity of the applicator is on the rear side. In the cosmetic applicator having an applying part provided at the front end of the barrel cylinder and a cosmetic stored in the rear of the barrel cylinder, a resilient member is mounted to the rear end of the barrel cylinder.
