Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair building solid applicators require two-handed operation, leading to inconvenience and clogging issues when used in vertical positions due to the need for manual air flow creation and nozzle alignment with the scalp shape.
Innovation Solution
A one-handed applicator design featuring an air pump for electrically creating airflow, with a nozzle and orifices configuration that directs air flow to prevent clogging by using inclined channels to enhance turbulence and airflow velocity, allowing for ergonomic use without manual bulb operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual bulb operation is used to create air flow, then the device complexity is reduced, but the ease of operation deteriorates because two hands are required
Solution Approach 1:
The patent replaces the manual mechanical bulb operation with an electric air pump system. The air pump is electrically connected to a power source and automatically creates air flow through the hair building solids, eliminating the need for manual bulb squeezing and enabling one-handed operation while maintaining adequate device complexity
Solution Approach 2:
The applicator is designed to be self-operating through the electric air pump that automatically generates air flow without requiring manual intervention. The system serves itself by using electrical power to drive the air pump, which continuously supplies air through the container and nozzle system without user intervention
2Adaptability or versatility
If the applicator is used in an inclined position to follow the scalp shape, then the adaptability is improved, but the reliability deteriorates due to nozzle clogging
Solution Approach 1:
The patent implements a vertically adjustable nozzle assembly that can dynamically change its orientation and position. The nozzle is connected to the applicator body through a joint mechanism allowing it to be positioned at different angles and heights, enabling the system to adapt to various scalp contours while maintaining optimal airflow direction to prevent clogging
Solution Approach 2:
The nozzle parameters including its angle, height, and distance from the scalp can be adjusted during operation. This allows the system to optimize the air flow trajectory and maintain reliable operation across different application scenarios and scalp geometries without clogging
3Manufacturing precision
If the nozzle is positioned close to the scalp for precise application, then the manufacturing precision is improved, but the object-affected harmful factors worsen due to increased clogging risk
Solution Approach 1:
The patent introduces vertical spacing and angular orientation as additional dimensions in the nozzle-to-scalp relationship. Instead of only horizontal positioning, the nozzle can be adjusted in height and angle, creating optimal airflow pathways that maintain precise application while preventing clogging through three-dimensional positioning

Function Achieved in This Case
Enables efficient, one-handed application of hair building solids without clogging, maintaining effective airflow and turbulence for uniform distribution on the scalp, regardless of the applicator's position relative to the scalp shape.
Implementation Method 1
an air pump electrically configured for creating an air flow
Implementation Method 2
The first channel part is inclined such that the air flow coming from the air pump is directed toward that side wall of the container which is nearest to the first orifice
