Modular Hair Brush with Refillable Fluid Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair brushes combined with liquid dispensers are not economical to manufacture and often use non-refillable aerosol containers that are harmful to the environment.
Innovation Solution
A hairbrush design featuring a modular structure with interchangeable halves and a container that allows for easy assembly and disassembly, using male and female connectors to securely hold a fluid storage unit, enabling the use of refillable liquids and reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aerosol spray containers or non-refillable containers are used in prior art brushes, then liquid dispensing function is achieved, but environmental harm increases due to disposal requirements
Solution Approach 1:
The patent implements a refillable container system where the liquid container can be removed from the brush head and refilled externally. This allows the container to be recovered and reused multiple times, eliminating the need to discard entire aerosol or non-refillable containers after use, thereby reducing environmental harm while maintaining reliable liquid dispensing function
Solution Approach 2:
The brush is divided into separable components: a reusable brush head and a removable liquid container. This segmentation allows the container to be independently refilled or replaced without discarding the entire brush assembly, enabling sustainable reuse and reducing environmental impact
2Reliability
If complex dispenser mechanisms are used in prior art brushes, then liquid dispensing capability is achieved, but manufacturing cost increases
Solution Approach 1:
The dispenser system is segmented into simple, modular components: a brush head with basic connector structures and a separate container with complementary connectors. This segmentation simplifies manufacturing by allowing each component to be produced independently using basic molding techniques, reducing overall manufacturing complexity and cost while maintaining functional reliability
Solution Approach 2:
The complex mechanical dispenser mechanisms found in prior art are extracted and replaced with a simple removable container system that uses basic connector geometry. This extraction of complexity reduces manufacturing costs while the container itself provides the liquid dispensing capability through its simple removal and attachment to the brush head
3Ease of operation
If modular structure with connectors is implemented, then ease of assembly and disassembly is improved, but device complexity increases
Solution Approach 1:
The brush is segmented into modular components (brush head, container, cap) connected by simple connector elements. This segmentation enables easy assembly and disassembly through straightforward connector engagement, while the connectors themselves are designed with simple geometry that does not significantly increase overall device complexity
Solution Approach 2:
The connector design serves multiple functions: mechanical attachment, alignment, and sealing. This multi-functionality reduces the need for separate complex mechanisms, allowing easy assembly and disassembly without proportionally increasing structural complexity

AI summary
A hairbrush includes a body having a first half and a second half, and a container therebetween for storing fluids like liquids, i.e., water, alcohol, lotions, creams, etc. The first half and second half include respective bottom parts of a generally rectangular configuration each extending to an elongated portion extending to an open front. The first half and second half include respective inner surfaces and outer surfaces, with the second half including a flexible core from which a plurality of bristles extend radially outwardly.
