Motor Driven Pruning Saws TRIZ Cases

A pump-fed wax or grease reservoir lubricates the guide bar with less leakage and mess than oil while improving chain wear resistance.

An inclined handle switch panel improves switch visibility and operability during tilted electric work, helping reduce erroneous operation.

This cutter machine case uses a more deformable hand guard to preserve finger protection and the desired cutting posture around obstacles.

Ground operators control a robotic climber to cut branches, removing personnel from elevated work zones.

Curved teeth on a gripper bar hold small limbs in place, preventing kickback and enabling safe chainsaw operation.

Relocating the electric motor to the handle end shifts weight distribution, resolving unwieldy operation caused by long poles and heavy tool heads.
