Scalp Applicator With Pump-Activated Hollow Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scalp therapy tools lack an efficient mechanism to apply liquid cosmetic media uniformly and comfortably to the scalp while avoiding tangles and snags, and do not effectively activate a pump mechanism for distributing the media.
Innovation Solution
A scalp applicator comprising an applicator comb with splayed, arc-shaped teeth, a snapping cap that activates a pump when compressed, and a solution container with finger rests to distribute liquid cosmetic media through a manifold to the teeth, ensuring snag-free application and uniform distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional applicator is used to apply liquid cosmetic media to the scalp, then the application process is simple, but the distribution is non-uniform and causes tangles and snags
Solution Approach 1:
The applicator head is segmented into multiple hollow teeth that independently receive and distribute cosmetic media through internal channels to multiple outlets along each tooth, ensuring uniform distribution across the scalp while the comb structure prevents hair tangles
Solution Approach 2:
The cosmetic media reservoir is nested within the applicator handle, and the hollow teeth are nested within the applicator head structure. The manual pump mechanism is integrated into the handle, creating a compact nested arrangement that maintains simplicity while enabling controlled distribution
2Productivity
If a manual pump mechanism is added to control media distribution, then the distribution control is improved, but the device complexity increases
Solution Approach 1:
The manual pump mechanism is designed to be self-activating through finger pressure on the applicator handle. The pump chamber compresses under finger pressure to force media through the manifold and hollow teeth, eliminating the need for separate activation mechanisms while maintaining efficient distribution control
Solution Approach 2:
The pump activation mechanism is merged with the applicator handle structure itself. The finger rest area of the handle serves dual purposes: providing structural support and acting as the compression surface for pump activation, thereby reducing overall device complexity
3Object-affected harmful factors
If the applicator teeth are solid and rigid, then the structural strength is high, but the application causes snags and discomfort
Solution Approach 1:
The teeth are designed with hollow interiors containing fluid channels, creating different properties in different parts: the external structure maintains sufficient strength for structural support, while the internal hollow channels enable cosmetic media distribution through multiple outlets along each tooth, preventing snags by allowing smooth media flow
Solution Approach 2:
The distal ends of the teeth are rounded rather than sharp or angular, creating a smooth curved surface that prevents hair snagging and scalp irritation while maintaining adequate structural strength through the hollow cylindrical geometry
