Adjustable Brush With Rotatable Tooth Carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grooming brushes are ineffective for different animals due to fixed tooth spacing, which may not align with the unique characteristics of the animal's fur or hair, leading to discomfort and inadequate grooming.
Innovation Solution
An adjustable brush design featuring a brush head with two sets of teeth that can be independently rotated, allowing for variable tooth spacing adjustment via a knob mechanism, enabling the teeth to transition between extended and retracted positions to accommodate different fur or hair types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spacing between protrusions is fixed, then the brush structure is simple and easy to manufacture, but the brush cannot be adjusted to suit different animal fur characteristics
Solution Approach 1:
The patent applies the dynamics principle by making the tooth spacing adjustable rather than fixed. The brush includes a carriage that can be rotated relative to the brush head, changing the spacing between teeth. This allows the brush to adapt to different fur characteristics (long, short, thick, thin) by adjusting the tooth spacing, while maintaining a relatively simple overall structure through the use of a rotation mechanism rather than completely redesigning the brush architecture.
Solution Approach 2:
The patent applies the parameter changes principle by varying the tooth spacing parameter to suit different grooming needs. The carriage rotation mechanism changes the effective spacing between teeth, allowing the same brush to provide different tooth densities for different animal types. This parameter adjustment enables versatility without requiring multiple different brush designs.
2Productivity
If the tooth spacing is too wide, then the brush structure is simpler with fewer teeth, but the grooming effectiveness is reduced and animal comfort is compromised
Solution Approach 1:
The dynamics principle resolves this contradiction by allowing the tooth spacing to be dynamically adjusted based on the animal being groomed. When grooming animals with dense fur, the carriage can be rotated to provide narrower tooth spacing for effective grooming. When grooming animals with sparse fur, the carriage can be rotated to provide wider tooth spacing. This dynamic adjustment ensures high grooming effectiveness without permanently increasing device complexity.

AI summary
An example adjustable brush may include a brush head and a handle extending from the brush head. The brush head may include a first plurality of teeth extending along a rotation axis and a second plurality of teeth extending along the rotation axis. The second plurality of teeth may be rotatable independently of the first plurality of teeth about the rotation axis.
