Aerosol Applicator Comb Teeth Stem Press Moment Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional applicator-equipped aerosol containers with comb-teeth parts face difficulties in stably and efficiently applying hair treating agents while combing hair, as the finger-placing part for pressing the stem is often close to the stem, applying a large moment force to the comb-teeth, making precise application challenging, especially when trying to dye specific hair regions.
Innovation Solution
The design includes a comb-teeth part with inclined comb teeth and a finger-placing part arranged above an imaginary extension line opposite to the comb teeth's direction, integrated with a cantilevered stem press-down mechanism, allowing the head part to press the stem and eject the hair treating agent directly to the comb-teeth part, enabling easier and precise application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the finger-placing part is positioned close to the stem part, then the stem can be pressed downward effectively, but a large moment force is applied to the comb-teeth part making precise application difficult
Solution Approach 1:
The patent repositions the finger-placing part from a location close to the stem to a location above an imaginary extension line opposite to the comb teeth direction. This spatial reconfiguration changes the moment arm geometry, reducing the moment force applied to the comb-teeth while maintaining effective stem pressing capability.
2Ease of operation
If the finger-placing part is positioned far from the stem, then the moment force on comb-teeth is reduced, but the stem pressing effectiveness decreases
Solution Approach 1:
The patent optimizes the position of the finger-placing part by placing it above an imaginary extension line opposite to the comb teeth direction. This positioning creates an optimal moment arm configuration that reduces moment force on the comb-teeth while maintaining sufficient stem pressing effectiveness through the cantilevered head part structure.
3Ease of operation
If the comb teeth extend in a direction outward from the cap part, then combing function is improved, but the finger-placing part arrangement becomes constrained
Solution Approach 1:
The patent employs asymmetric positioning where the comb teeth extend in one direction outward from the cap part, while the finger-placing part is positioned above an imaginary extension line in the opposite direction. This asymmetric arrangement allows both the combing function and the stem pressing function to operate independently without interference, simplifying the overall device design.
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
This configuration allows for stable and efficient application of hair treating agents while combing, reducing the moment force on the comb-teeth and enabling accurate application to specific hair regions with reduced finger pressure, improving user experience and application precision.
Implementation Method 1
the head part is pressed downward by employing the cantilever base-end part as a support part, and thereby, the head part downwardly presses the stein part

AI summary
An applicator-equipped aerosol container includes an aerosol main body, and an applicator that includes comb-teeth attached to an upper end section of the aerosol main body. Contents of the applicator-equipped aerosol container may be, for example, chemical agents, cleaning agents or hair treating agents. Contents can be ejected from the applicator-equipped aerosol container by pressing down on a stem part of the container such that contents are dispensed from the aerosol main body of the container through the comb-teeth.
