Bristle TRIZ Cases

Vertical non-contact heating forms symmetrical bristle head profiles, eliminating gravity-induced asymmetry and burrs.

A tapered through hole narrows from rear to front to guide brush movement and prevent bristle catching.

Segmented brush heads use replaceable bristle parts with varying stiffness to clean planar and concave kitchen surfaces.

Segmented bristle regions enable deep pocket penetration while preventing repulsive forces that cause user fatigue during cleaning.

Adhesive-filled pockets bond the ferrule to the handle while a rigid spine supports a flexible grip.

Protrusions on bristle tips retain hair against the heating surface, resolving heat transfer and snagging trade-offs.

A mascara kit uses a heating applicator to optimize composition application.

Cross-shaped filaments with four projections increase bending stiffness to improve plaque removal while reducing wear and gum injury.

Flexible refill deformation controls liquid flow through projection holes, preventing leakage while enabling adjustable dosage.

Varying strand inclination angles eliminate central zone gaps and prevent dirt displacement for comprehensive cleaning.

A splitting apparatus directs filament bundles through channels to form precise tufts.

Waterproof silicone walls contain liquids while bristles access interdigital spaces.

An integrated oral care implement merges a rupturable dentifrice dispenser into the bristle field to eliminate separate packaging while maintaining hygiene.

Inclined tufts with varying filament lengths resolve inadequate interproximal cleaning while preventing gum injury.

A toothbrush integrates a flat light emission surface with an internal condensing lens to direct radiated light toward the reception portion.

Cross-shaped filaments with concave channels improve plaque removal while reducing gum injury risk through asymmetric stiffness distribution.

A toothbrush head features a continuous wave-shaped cleaning surface with inclined filaments extending at varying lengths to penetrate interdental spaces.

Curved spiral walls create enclosed spaces between arms and the center, preventing toothpaste slippage while conforming to tooth curvature.

A conically-shaped cavity formed by non-parallel bristles retains dentifrice at the contact zone, preventing slippage through the tufts.

A hairbrush with integrated vibration sensors measures bristle movement during brushing to determine hair characteristics.

Alternating curved and straight spikes on a cosmetic applicator core create distinct product reservoirs for controlled lash loading.

Segmented bristle zones on a twisted core resolve manufacturing complexity while improving product loading and separation at the eye corner.

A magnetic hairbrush sprays cosmetic composition toward hair using an electric circuit to deliver product without water.
