Powder-Dispensing Brush With Rotating Hole Alignment for Even Grooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry shampoo applicators and brushes for pets face challenges in controlling the amount of product dispensed, achieving even distribution, and ease of use, particularly for pets with dense or long coats, leading to uneven grooming results and a stressful experience for both pets and owners.
Innovation Solution
A brush design featuring a tube portion with discharge holes, a brush portion with bristles, and a mechanism allowing controlled release of cleansing compound through aligned holes for even distribution, combined with ergonomic handles for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional dry shampoo applicators are used, then the product can be applied to pets, but the distribution through the fur is uneven particularly in animals with dense or long coats
Solution Approach 1:
The brush portion is segmented into multiple bristle rows with dispensing holes distributed across the plate surface. This segmentation allows the cleansing compound to be delivered through multiple discrete points simultaneously, creating a more uniform distribution pattern across the pet's coat compared to single-point applicators.
Solution Approach 2:
The brush portion acts as an intermediary between the cleansing compound reservoir and the pet's coat. The bristles serve as a mediating element that distributes the compound evenly through mechanical contact with the fur, solving the distribution uniformity problem while maintaining ease of operation through simple brushing motion.
2Quantity of substance
If existing applicators dispense dry shampoo, then cleaning occurs, but the amount of product dispensed cannot be controlled leading to insufficient or excessive application
Solution Approach 1:
The system uses a rotatable brush portion that can be positioned at different angular orientations relative to the reservoir. By rotating the brush, users can control which set of dispensing holes aligns with the corresponding discharge holes, thereby controlling the amount of product dispensed. This dynamic positioning mechanism provides quantity control without requiring complex dosing systems.
Solution Approach 2:
The applicator is designed to dispense product in periodic cycles as the brush rotates. Each rotation cycle brings different dispensing holes into alignment with discharge holes, creating a periodic dispensing pattern that allows control over total product amount while maintaining simple device architecture.
3Productivity
If dry shampoo is applied to pets, then hygiene is improved, but the application process is cumbersome and inefficient
Solution Approach 1:
The applicator merges the reservoir, dispensing mechanism, and brush function into a single integrated unit. The brush portion can be attached to or separated from the reservoir, combining multiple functions (product storage, controlled dispensing, and mechanical application) into one device, thereby improving grooming efficiency while maintaining ease of operation through simple attachment and detachment.
4Measurement precision
If the brush portion rotates to align holes for product release, then controlled dispensing is achieved, but the rotational mechanism must be precise to avoid misalignment
Solution Approach 1:
The brush portion and reservoir are designed with asymmetric features including protrusions and recesses that guide rotational alignment. These asymmetric elements ensure that when the brush is attached or rotated, the dispensing holes automatically align with the discharge holes in a specific orientation, achieving precise hole alignment without requiring complex adjustment mechanisms.

AI summary
A brush for applying a cleansing compound with an inner body having a tube portion with outer proximal threads. The tube portion has an opening for filling the tube portion with the cleansing compound and an enclosed bottom having a central guide tooth receptacle and a plurality of discharge holes. The brush has a brush portion including a plate having at least one upstanding standoff, a central guide tooth, and a plurality of depending bristles. The plate has a plurality of dispensing holes and an upstanding collar configured to secure the plate against the enclosed bottom of the inner body. The central guide tooth fits into the central guide tooth receptacle to guide rotation of the brush portion with respect to the inner body. In an open position, the plurality of discharge and dispensing holes are aligned so that the cleansing compound passes into the plurality of depending bristles.
