Bristle TRIZ Cases

A mascara brush mounts bristles on a flat surface to increase makeup material retention and application efficiency.

Oral hygiene device merges an edible confectionary handle with a rotary cleaning head to eliminate separate agents and enable discreet public use.

Segmented polymer tabs flex to follow nail curvature, eliminating streaks caused by rigid straight tips.

Angled staple grooves secure brass bristles without deformation, solving retention issues while lowering material costs.

A travel toothbrush integrates a handle cavity and compression section to extrude paste through an interior channel.

Segmented bristle zones form a central reservoir that beads liquid while the outer zone buffs it out, eliminating streaks from uneven absorption.

Inclined tufts feature pointed bristles to enhance cleaning performance on tooth surfaces.

Par-elliptical and arcuate bristle rows form a closed loop that retains dentifrice against slipping, improving cleaning efficiency along the gum line.

A mascara brush primary branch forms a closed loop with inner and outer blades to hold formula.

Triangular tuft holes increase packing factor to eliminate gaps and improve dentifrice retention.

Intertwined coextruded strands deliver multiple oral care additives simultaneously, overcoming single-treatment limitations.

Chemical tipping reduces wall thickness of hollow synthetic bristles to create tapered split ends.

Triangular spike geometry balances longitudinal flexibility for easy withdrawal with transverse rigidity to maintain lash separation and product loading.

Ridges and channels mediate hydrophobic emulsion transfer to wet teeth, preventing accumulation for consistent deposition.

A mascara container features a detachable brush assembly for easy refilling.

Helical grooves on the bristle increase specific surface area and adhesion, resolving insufficient liquid retention in smooth designs.
