Hand Equipments TRIZ Cases
- Hand-Held Lawn Aerator With Detachable Multi-Nail Punching Assembly
A hand-held, foot-pedaled aerator uses detachable multi-nail punching to improve lawn aeration while reducing slipping, complexity, and maintenance.
- Interchangeable Tool Joint with Tapered Threaded Load Transfer
A tapered male-female joint lets one handle fit multiple tool implements while protecting threads, improving transport, replacement, and strength.
- Rolling Lawn Aerator Pipe Assembly for Low-Resistance Soil Penetration
Rotatable perforating pipes and elastic limiting members keep entry and extraction near vertical, cutting lawn damage and soil resistance.
- Open-Faced Bevel Tine Aerator for Penetration and Core Ejection
This hollow tine aerator uses a 45-degree bevel and open channel to ease compacted-soil penetration and guide cores upward.
- Ground Aeration Device with Hydraulic Depth Adjustment
Hydraulic carriage adjusts drill depth to aerate compacted soil layers, resolving single-depth limitations and improving drainage efficiency.
- Rotatable Gardening Handle Latch Mechanism for Angle Stability
An impediment pin engages cavities to lock the handle angle, preventing unintended rotation caused by user-applied torque during gardening operations.
- Handheld Material Moving Tool with Swivel Handle
A handheld material moving tool features a swivel handle positioned low on the implement for ergonomic pivoting.
- Military Shovel Hinge Locking Mechanism for Safe State Positioning
Locating protrusions align with connection seat holes to prevent automatic rotation, resolving injury risks from unintended head movement.
- Hollow Turf Aerator Tine with Core Splitting Wall
Segmented hollow tines split aeration cores to reduce decomposition time and prevent machinery fouling.
- Parallel Blade Cutter for Uniform Zipper Flange Gaps
Segmented blades and angled guides produce uniform cuts between zipper flanges, eliminating irregular material flaps that interfere with operation.
