Chain Saws TRIZ Cases

A dual extension chamber system vents thermal expansion pressure from the chainsaw oil tank through a one-way valve, preventing oil leakage during tilting.

A pivot arm mounts interchangeable circular blades and chain assemblies to a single drive motor.

A portable work apparatus housing features a lateral discharge opening with a height of at least 5 mm to eject saw chips from the drive sprocket area.

Counteracting pressures applied to structural lay-ups prevent buckling and warping of shear webs, ensuring precise geometric features in cured composites.

Keyhole slots and spring tension allow fast saw chain replacement without full disassembly, preventing part loss in harsh conditions.

Segmented oil inlets and internal channels distribute lubricant to reduce splashing and improve utilization efficiency.

Segmented compartments and nested latches keep chains untangled, eliminating time lost to manual separation.

A guide wheel cooling liquid delivery system channels fluid through internal inlet and guide passages to lubricate bearings.

Internal divergent grooves route lubricant past the rotating sprocket to prevent centrifugal force from throwing off oil and causing premature bearing wear.

A detachable protective cover shields the operator from sawdust while a pre-installed stop pin intercepts broken chains.

A tension knob positioned below the chain bar forms a catcher groove with the housing cover to trap the chain during breakage.

A control unit monitors hydraulic pump pressure to dynamically adjust saw cutting force during harvesting operations.
