Window Cleaners TRIZ Cases

Segmenting the hub body from the spring tongue reduces fitting effort without compromising guide properties or connection strength.

Nesting the support element within an integrated connecting plate and longitudinal channel reduces friction while protecting the spring rail.

Retaining plates and blocking structures prevent liquid re-entry into the air stream, protecting internal components from water damage.

Protrusions engage holes in the oscillating arm to prevent the wiper blade from loosening under high forces.

An integrated wiper clip attaches a scrubbing brush to the blade frame, resolving the contradiction between water removal and bug adhesion.

A rear wiper motor assembly integrates a kill switch that cuts power when the arm leaves the window, preventing energy waste and fluid leakage.

Apertures in the brush head minimize venturi effects while a movable hydrofoil plate adjusts pressure against the sidewall during cleaning strokes.

An insert molded metal reinforcement member strengthens the plastic retainer against wear from repeated toggle actions and automatic car wash exposure.

A self-cleaning wiper blade system pivots blades outward via a solenoid and spring mechanism to discharge accumulated debris.
