Rakes TRIZ Cases

A swivel knuckle and clamp sleeves let two yard tools couple fast, rotate freely, and scoop debris with less bending effort.

A universal fastener and stand keep garden and construction tools off the ground, reducing bending strain while improving access and comfort.

A high-durometer polyurethane connector joins two rake handles, adds restoring bias, and holds leaves securely during transfer.

A motorized waste catch and drive train collect pet waste one-handed, reducing lever-arm torque, handling difficulty, and fecal contact.

A wheel-supported rake uses tool weight and gravity to press the rake heads, enabling one-handed thatching with less back, wrist, and shoulder strain.

A sliding adapter links two rakes into scissor tongs, keeping handle alignment while reducing back strain and breakage during debris pickup.

A motorized lute uses sliding toothed plates and lateral motor oscillation to speed grading, leveling, and buildup prevention.

Segmented tapered channels guide vegetation into pinch points, resolving the trade-off between secure grasping reliability and manufacturing complexity.

Arm-engaging loops on dual rakes inhibit rotation during grasping, reducing wrist strain while securely lifting heavy debris piles.

Segmented rake head with front blade, tines, and rear blade eliminates furrows and ridges during single-pass raking.

A multi-use raking system combines two rake heads via a connector allowing variable positioning and orientation adjustment.

Rotating coupling secures interchangeable heads to a telescopic handle, reducing storage space while maintaining task versatility.

Spring-mounted tines pivot up to 45 degrees to prevent getting stuck while maintaining load grip during raking operations.

A rearward-facing rake edge sweeps animal waste onto tines during a pulling motion.
