Portable Power Driven Saws TRIZ Cases

Adhesive bonding and form-locking contours secure tool guides to work surfaces without screws, surface damage, or residue.

An adhesive and form-locking holder secures tool guides firmly for precise machining without nails, screws, or workpiece surface damage.

An adhesive, formfitting holder secures guide contact bodies on work surfaces without screws, damage, or residue while preserving precise positioning.

A fixed-angle mounting element tilts the guide rail so a hand-held circular saw can make miter cuts beyond 45° without complex adjustment.

An adjustable stop lets a circular saw be preset on the guide carriage off the rail, improving positioning flexibility without losing accuracy.

A drop-on retention element and lateral clamp let accessories mount anywhere on a T-slot while preserving precise alignment without end insertion.

A spring-loaded blade offset arm marks the cut line while the guide edge aligns the saw baseplate for accurate portable crosscuts.

A two-body angle stop with quick-release clamping fixes work components at precise variable angles while simplifying machining setup.

A movable guide-rail stop holds the protective cover open during cutting and lets it return to the covering position afterward.

A spring-loaded protective wedge encloses the cutting edge while a touch sensor triggers rapid braking to prevent user injury.

A rotating support ring mounts on the motor shaft to guide handheld cutting tools along material surfaces.

A U-shaped groover handle with sliding grips enables dynamic reconfiguration for horizontal and vertical masonry cutting.

Asymmetric cordless circular saw layout positions the battery pack and control circuit board to balance the gravity center along the handle axis.

A protective cover for power tools uses a spring-biased guide body and adjustable depth stop to reduce operator effort while maintaining cutting accuracy.

A rolling plate assembly with fiber enriched plastic and removable wheels enables smooth movement of portable power cutting tools.

Dual-side connecting members on the adapter base accommodate various tool sizes, preventing shifting movements during cutting operations.

A portable circular saw uses a flexible cable transmission to move locking elements for cutting parameter settings.

A cutting depth limiting device uses a spring-loaded pre-positioning element to move the fixing element toward its release position.

A circular saw bevel adjustment mechanism uses opposing torsion springs and a manual release bar to unlock the pivot for single-handed angle changes.

Segmented motion and spacing units isolate the drive spindle from guide track wear, extending tool service life.

Segmented angled handle surfaces enable quick angle adjustments, reducing setup time for woodworking cuts.

A rotatable limiting element mounted on a machine tool functional unit sets maximum cutting depth via an axial fixation collar.

A powered circular saw uses a single mode selection pin engaging concentric arcs to lock the tool body into one operational state.

Relocating the control unit to the base lower surface prevents handle interference and improves maneuverability.

A cut-depth limiting device uses a pivotable stop element to set precise cutting depths on portable machine tools.

Complementary reference surfaces enable direct alignment of work components, eliminating manual marking steps that cause dimensional variations during routing.

A universal depth adjustment device integrates stop, display, and fixing functions into a single setting body for hand-held cutting machines.

A portable cutting tool adjusts blade protrusion via a link part and guide mechanism.

Inwardly extending support dowels retain incised portions to prevent bending, buckling, and saw binding during sheet board sectioning.

A rechargeable plate joiner mounts its battery pack on the motor housing side for easy attachment.

Removing redundant bearings from the clamping nut side reduces friction and installation space while maintaining stable cutting depth control.

A hand cutting machine positions a front miter bearing laterally to expose the tool penetration area.

Segmenting the handle routes motor cords away from the grip, reducing line resistance to prevent voltage drops and heat generation.

A spring deactivation device controls the return spring mechanism to manage drive assembly positioning in manually operated cutting machines.

Actuating element releases tool holder hold to shift depth position, resolving safety and accessibility contradiction.
