Brushes TRIZ Cases

Capacitive sensors replace mechanical switches to eliminate water infiltration while micro-suction tape enables hygienic vertical storage.

A cosmetic applicator featuring a curved applying portion with a longitudinal concavity and flocking finish.

An asymmetric applicator dispenses personal care products directly onto skin while a flow-restricting member prevents water entry and reduces product waste.

Self-service friction fit cleans wheels without adding rolling resistance or requiring permanent alterations.

An electric toothbrush detects plaque via imaging sensors and adjusts bristle pressure to remove deposits while preventing gum abrasion.

A toothbrush handle encloses a flexible film chamber that releases paste through a cap spike.

Hall effect sensor detects drive shaft speed changes to replace mechanical switches, ensuring continuous monitoring and reducing manufacturing costs.

Segmenting the wiper into distinct ends resolves the contradiction between aesthetic shape requirements and effective product removal efficiency.

An electronic toothbrush uses accelerometers to analyze user brushing motion characteristics and deliver immediate corrective guidance.

Tapered inner sleeves prevent dew condensation and tip drying by forming protective air gaps within nested cap structures.

A comb with helical twisted teeth penetrates tangled hair to separate fibers and remove debris during use.

A magnetic closure system replaces screw threads on wand applicator containers to enable easy operation.

A telescopic hand extension uses a universal clamp to securely attach any tool for remote operation.

Segmented rigid shells and elastic deformation constrain the brush handle, preventing bristle damage and luggage contamination.

Integrally formed metal core joint head resolves orientability and assembly complexity trade-offs in mascara applicators.

A paint brush storage device uses a latching seal to protect bristles from damage.

An elastic rubber wiper accommodates non-circular cross-sections, resolving design limitations of rigid circular wipers.

A cleaning apparatus directs a supercritical fluid stream to dislodge particles from substrates.

Segmented injection molding embeds decorative particles in a core visible through a translucent shell, resolving aesthetic complexity trade-offs.

Segmenting the input mechanism into a separate wireless unit resolves the trade-off between user customization and device complexity.

Segmented teeth with individual channels ensure uniform distribution of scalp treatment compositions, preventing clumps during application.

A mechanical switching element made of elastic material provides multiple static states within an oral hygiene product handle.

Segmented bottle reservoirs position applicator tips near the bottom, preventing fluid waste when the cap is unscrewed.

Alternating dielectrophoretic forces disintegrate biofilms and enable targeted cleaning agent delivery to hard-to-reach areas.

An integrated toothbrush holder uses a wedge squeezer to dispense paste efficiently, resolving the trade-off between component complexity and hygiene.

A personal hygiene device uses object recognition to identify designated features on the user and implement.

Segmented hanger rods pivot within grooves to engage rims, preventing paint mixing and spills during use.

Collapsible fins on an elastomeric wiper body flex during insertion then engage the container shoulder, preventing accidental removal of the applicator head.

A detachable handle subassembly connects to a disposable container subassembly to form an electric heating circuit for personal care products.

An oral irrigator tip integrates a bristle element near the nozzle to mechanically pick debris from between teeth while delivering fluid irrigation.

Pressurized water jets from segmented nozzles remove dried paint while bristle spreaders separate fibers, eliminating manual scrubbing effort.

A mascara brush features a jointed shaft and slant guiding surface that tilts the bristles during use.

An integrated retractable applicator mechanism reduces powder waste and spilling while saving storage space.

An X-ray ink pen dispenses a fluid mixture containing radiopaque particles to deposit visible markings on diverse surfaces.

A processing unit acquires sensor data to detect distractive events during personal care activities and initiates counter-measures.
