Solution Overview
Problem
Existing hairdressing tools lack an efficient mechanism for applying liquid cosmetic media evenly and effectively to the scalp and hair, particularly in terms of generating sufficient motive force for distribution through a comb-like structure.
Innovation Solution
A scalp applicator comprising a compressible bellows and a manifold with non-Euclidean prism-shaped teeth, where the bellows generates motive force to push the liquid cosmetic media through the manifold and teeth for uniform distribution on the scalp and hair, mimicking a comb's action.

Engineering Contradiction Analysis
1Area of stationary object
If a traditional comb-like structure is used for applying liquid cosmetic media, then the application coverage is improved, but the motive force generation for distributing the liquid is insufficient
Solution Approach 1:
The applicator is divided into two functional segments: a bellows component for generating motive force and a comb-like manifold component for distribution. This segmentation allows each part to specialize in its function - the bellows provides compression force while the manifold with multiple teeth ensures wide coverage distribution across the scalp.
Solution Approach 2:
The bellows operates as a pneumatic/mechanical compression device that generates pressure to force liquid cosmetic media through the manifold. By utilizing compressible air or fluid pressure within the bellows, the system overcomes the insufficient motive force problem while maintaining effective liquid distribution through the comb-like structure.
2Productivity
If a compressible bellows is added to generate motive force, then the liquid distribution effectiveness is improved, but the device complexity increases
Solution Approach 1:
The bellows and manifold are merged into a single integrated unit where the bellows forms the handle and the manifold with teeth extends from it. This merging eliminates the need for separate pumping mechanisms and connection components, reducing overall device complexity while maintaining effective liquid distribution through the combined structure.
Solution Approach 2:
The bellows serves multiple functions: it acts as the handle for gripping the applicator, serves as the compression chamber for generating motive force, and provides the structural connection to the manifold. This multi-functionality reduces the need for additional components, thereby reducing device complexity while improving liquid distribution effectiveness.
3Force
If the bellows is made highly compressible to generate sufficient pressure, then the motive force is improved, but the control precision for liquid discharge is reduced
Solution Approach 1:
The bellows is designed with dynamic compressibility, allowing the user to adjust the compression level according to the desired liquid discharge rate. The flexible bellows material and structure enable progressive compression from gentle to firm, providing proportional control over the motive force generated and thus maintaining control precision while achieving sufficient pressure when needed.
Solution Approach 2:
The compressibility parameter of the bellows is optimized to provide a range of pressure outputs rather than a fixed high pressure. By selecting materials and structural parameters that allow variable compression, the system achieves sufficient motive force for effective distribution while maintaining user control over the discharge rate and precision of application.
