Mechanical Machines/Dredgers TRIZ Cases
- Distributed Hydraulic Control for Excavator Lift Arm Hose Routing
Segmented control valves mounted on the lift arm reduce hose routing complexity through swing mounts and minimize leak points.
- Rotatable Operator Station Control System for Safe Orientation Adjustment
A control system transitions between locking and unlocking states to manage operator station rotation based on machine suitability data.
- Work Machine Blade Position Control Using Optical Copying
Camera-based optical copying replaces physical masts to determine blade position, eliminating theft risks and reducing device complexity.
- Motor Grader Circle Drive Torque Control
Real-time sensor feedback modulates blade speed and torque during ground engagement, preventing motor overheating while maintaining surface evenness.
- Excavator Assistance System for Uniform Truck Loading
An assistance system provides loading strategies and payload distribution data to excavator operators.
- Mobile Fence Post Alignment and Wire Tensioning Apparatus
A mobile apparatus aligns fence post apertures while maintaining wire tension during installation.
- Dozer Blade Control via Segmented Hydraulic Cylinders
Independent tilt, angle, and side shift cylinders eliminate cross-functional interference to correct grade errors in a single pass.
- Excavation Apparatus Extension Element Verticality Control
A movable extension element maintains verticality of excavation means, reducing transverse pipe stress during deep digging operations.
- Excavator Control System Mode Mapping for Operator Fatigue
Dynamic mode mapping reassigns control parameters to reduce operator fatigue and boost productivity during excavator operation.
- Convertible Excavator Bucket With Pivoting Side Wings
Adjustable side plates pivot outward to maximize volume capacity, resolving the trade-off between trenching versatility and material handling efficiency.
- Sludge Harvester Suction Heads and Manifold Design
Air diffusers agitate settled solids in suction heads while a manifold directs the mixture to discharge tanks, reducing water changes.
- Skid Steer Loader Lift Arm Coplanar Linkage for Visibility
Coplanar lift assemblies and joining plates position behind the operator compartment, preventing obstruction of the field of vision during boom movement.
- Construction Equipment Attachment With Quick-Change Pin Mechanism
A construction attachment uses a pin drive to remove joint pins for rapid tool changes.
- Working Vehicle Attachment Interference Control
Independent stop position adjustment prevents interference without readjustment, maintaining working efficiency across varied attachments.
- Excavator Coupler Signal Port for Pin Engagement Verification
Signal port in hydraulic ram alerts operators to missed pin engagement, preventing accidental detachment.
- Bulldozer Engine Mounting Reduces Duct Vibration Load
Asymmetric rear mounting elevates the engine to shorten vertical distance, reducing vibration load on the air cleaner duct and extending component life.
