Lawn-Mowers TRIZ Cases
- Mower Deck Automatic Leveling via Ultrasonic Sensors
Ultrasonic sensors detect ground distance to calibrate electric actuators, resolving manual leveling inaccuracy and ensuring consistent blade alignment.
- Multi-Plane Laser Scanner for Agricultural Machine Surroundings Detection
Segmented scanning planes in a single sensor balance detection precision with device complexity, resolving the trade-off between range and resolution.
- Lawn Mower Power Unit Cooling via Forced Air Convection
Forced convection through dedicated air inlets removes heat from motor components, preventing thermal damage during operation.
- Outdoor Power Machine Steering Lever Speed Control
Integrated steering lever speed control button cycles through gross ranges while maintaining fine adjustment, eliminating separate hand positions.
- L-Shaped Rear Suspension Arm for Mower Fuel Tank Clearance
Rear suspension arm uses an L-shaped configuration to lift a lawn mower while avoiding interference with the fuel tank.
- Asymmetric Lawn Mower Blade Aerodynamic Lift
An asymmetric lawn mower blade generates air buoyancy to offset machine tool head gravity, reducing user lifting effort.
- Lawnmower Wheel Cleaning Device for Grass Build-up Reduction
Cleaning device removes grass build-up from lawnmower wheels to enhance operational reliability and cutting uniformity.
- Agricultural Machine Safety Device with Articulated Lifting Kinematics
Articulated safety mechanism lifts tools over obstacles, reducing structural complexity while maintaining shock absorption.
- Mower Swathing Unit Axial Radial Ejection
Reconfigurable swathing auger ejects crop axially or radially, eliminating separate conditioning units and reducing tractor wheel compaction.
- Multi-segmented Deck Plate Auto Adjustment for Harvester Row Units
Segmented deck plates with biasing members adapt to varying row spacings and stalk sizes, reducing grain loss by closing gaps where no stalk exists.
- Lawn Mower Drive Motor Disengagement via Tilt Sensor
A lawn mower controller disengages the drive motor based on tilt sensor signals to enable safe turning.
- Bogie Wheel Track Assembly for Zero-Turn Mowers
A bogie wheel assembly supports vehicle weight through a rocker mechanism, bypassing the drive axle to reduce drivetrain stress.
- Lawnmower Deck Suspension Using Turnbuckles and Polyurethane Bushings
Turnbuckle linkages with polyurethane bushings absorb shocks and limit deflection, resolving the trade-off between terrain adaptability and mowing stability.
- Belly-Mounted Snow Plow Leverage and Zero-Turn Radius
Mounting the plow between axles increases leverage on the blade while maintaining a zero-turn radius.
- Lawnmower Belt Cover Segmentation for Serviceability
A segmented belt cover uses interlocking tabs and pockets to shield the drive belt from debris while surrounding the vertical shaft.
