Rotating Deodorant Stick with Spring-Stabilized Balm Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic balm tubes face issues with inadequate structural design of elastic components leading to stability problems and recyclability challenges due to all-plastic construction.
Innovation Solution
A rotating structure deodorant stick with a housing and base case, featuring a rotary seat driven fork seat, metal or plastic springs, and a shaft holder with a V-shaped cut and snap groove, allowing for enhanced stability and recyclability through a combination of plastic and metal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an all-plastic structural design is used, then manufacturing ease and cost are improved, but recyclability deteriorates
Solution Approach 1:
The deodorant stick is divided into separate components: a plastic housing and a metal insert (shaft holder with spring mechanism). This segmentation allows the metal components to be easily separated and recycled independently from the plastic housing, resolving the contradiction between ease of manufacture and recyclability.
Solution Approach 2:
The product combines plastic and metal materials in a composite structure. The plastic housing provides manufacturing ease and cost benefits, while the metal insert provides recyclability. This composite approach allows each material to contribute its advantages while maintaining overall product functionality.
2Device complexity
If a simple structural design is used, then device complexity is reduced, but stability deteriorates
Solution Approach 1:
The spring-loaded shaft holder provides a dynamic mechanism that automatically maintains proper alignment and stability during rotation. The spring compensates for manufacturing tolerances and wear, ensuring consistent performance without requiring complex adjustment mechanisms.
Solution Approach 2:
The metal insert acts as an intermediary component between the plastic housing and the rotating shaft. It provides a stable, precise mechanical interface that ensures proper alignment and reduces wear, improving stability without significantly increasing overall structural complexity.
3Reliability
If plastic or metal springs are used, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The spring mechanism uses standard化的 spring parameters (material, diameter, length, coil density) that can be manufactured using conventional processes. By keeping the spring design within standard parameter ranges, the patent achieves reliable performance while avoiding excessive manufacturing complexity.

AI summary
A type of rotating structure deodorant stick includes a housing and a base case. The rotation of the rotary seat simultaneously drives the fork seat. The upper section of the fork seat contains a balm groove filled with the balm; wherein the hexagonal socket at the base of the rotary seat extends into the base case, both sides of the hexagonal socket are positioned against the openings at the ends of the plastic or metal springs within the base case. The opposing ends of the spring on either side within the base case are positioned against the inner wall of the case, while the shaft holder is securely fixed within the base case; one end of the opening of the spring features a V-shaped cut directed outward, while the opposite end of the symmetrical spring includes an inwardly extending snap groove.
