Bristle TRIZ Cases
- Bristle Tip Sharpening via Mechanical Grinding and Dynamic Rotation
Mechanical abrasion replaces corrosive chemicals to sharpen bristle tips, eliminating environmental harm while maintaining high manufacturing precision.
- Angled V-Shaped Filament Paintbrush for Trim Cut-In
Segmented angled V-shaped filaments prevent paint application to trim while maintaining efficient paint flow and user control.
- Ported Brush Applicator With Tapered Mesa For Leakage Prevention
A ported brush applicator uses a tapered mesa to channel liquid from the container into bristles via capillary action.
- Rotating Sponge Tip Device for Deep Mouth Cleaning
A battery-powered device with a rotating sponge tip dispenses mouthwash on demand to scrub oral surfaces.
- Segmented Boar Bristle Brush for Scalp Stimulation and Hair Waves
Segmented boar bristles create hair waves without thinning by penetrating the scalp to distribute natural oils and stimulate blood circulation.
- Porous Bristle Hairbrush Air Bearing Friction Reduction
Porous bristles release internal air to create an air bearing effect that reduces friction and prevents hair breakage during drying.
- Color-Coded Makeup Brushes and Face Charts for Strategic Application
Color-coded makeup brushes match face charts to guide strategic application steps.
- Cosmetic Container Sleeve Prongs for Bristle Distribution
Radially inward prongs in the sleeve guide bristles into gaps, resolving uneven line thickness from fixed apertures.
- Articulated Cosmetic Applicator Tip for Dual-Lip Application
Segmented application zones connected by an articulation means enable rocking movement, resolving rigidity issues while covering extended areas like both lips.
- Spiral Branch Applicator for Even Cosmetic Dosing
Segmented spiral branches rotate freely to deliver precise doses, resolving uneven distribution from smooth surfaces.
- Non-Circular Filament Tuft for Oral Care Stiffness
A tuft with non-circular filaments creates a scaled-up shape to increase bending stiffness and lifespan.
- Oral Care Implement With Peripheral Soft Tissue Cleanser
A toothbrush head integrates a resilient soft tissue cleanser around its peripheral edge to clean cheeks and tongue.
- Mascara Applicator Radial Plate Reservoir Design
Radial plate rows form angular interstices that store mascara, resolving inconsistent loading and coating of eyelashes.
- Applicator Air Communication Pipe Ink Leakage Control
Movable air pipe prevents ink leakage by separating gas exchange from storage.
- Applicator With Branch Cavity And Segmented Brush Strips
A cosmetic applicator uses a branch cavity and segmented brush strips to store product.
- Toothbrush With External Water Management For Oral Hygiene
A toothbrush uses a guide tube to connect with an external main body for fluid supply and suction.
- Structured Stem Capillary Absorption for Cosmetic Applicators
Porous stems wick liquid from reservoirs to brushes, eliminating frequent dipping and ensuring uniform application.
- Hair Wrapping Cap with Integrated Bristle System
Integrated bristles wrap hair without pins, eliminating discomfort while maintaining stability.
- Applicator Core Wiping Mechanism for Residue Control
A multi-region wiping action shears residue from the applicator free end, preventing unsightly deposits and ensuring precise eyelash application.
- Paint Brush with Storage Chamber for Uniform Application
Segmented storage bristles in a central chamber retain paint and release it gradually, preventing drips and ensuring uniform application.
- Laser Therapy Attachment Pins for Furred Animal Skin
Pins penetrate fur to deliver coherent therapy light, avoiding shaving and reducing light absorption.
- Cosmetic Applicator with Segmented Porous Foam and Projecting Fibres
Segmenting fibre length across zones balances product loading capacity with combing flexibility for eyelash application.
- Cross-Shaped Oral Care Filament Geometry for Plaque Removal
Cross-shaped filaments with concave channels increase bending stiffness and interdental penetration while reducing tuft wear during manufacturing.
- Cosmetic Container With Integrated Opening-Closing and Air Injection Mechanism
An integrated opening-closing mechanism and air injection system in a cosmetic container prevent powder leakage while ensuring reliable discharge.
