Vessel Cleaning TRIZ Cases
- Silicon Antifouling Coating Composition for Durable Impact Resistance
A silicon resin and polyfunctional acrylate coating film resists impact and maintains long-term antifouling performance in water.
- Roll-Up Boat Fender With Airtight Seal for Compact Storage
A roll-and-clip airtight shell lets this boat fender inflate without a pump, then store flat while still absorbing docking impact.
- Personal Watercraft Front Bumper Structure for Splash Deflection
A sloped front bumper, deck cover, and reinforcement member guide water outward to keep splash and infiltration out of the footwell.
- Magnetic Hull-Climbing Robot With Crutches for Surface Transitions
Magnetic tracks and rotatable crutches help a hull-climbing robot cross surface transitions for safer, more complete vessel cleaning and inspection.
- Vessel Cassette Assembly With Resilient Buffering for Offshore Access
A movable cassette with compressible buffer elements absorbs vessel impact, enabling safer personnel access to offshore structures.
- Polygonal Floating Offshore Structure for Deep-Water Stability
Polygonal columns and inward pontoons use buoyancy, mooring, braces, and dampers to keep offshore power structures stable in deep water.
- Vessel Maintenance Diagnosis Using Torque and Slip Indexes
Operational data is used to separate propeller fouling from hull fouling, enabling targeted cleaning that cuts fuel use and avoids premature maintenance.
- Portable Marine Mammal Deterrent Circuit With Resistance Feedback
Resistance-triggered electrification deters marine mammals non-lethally while improving vessel portability and NOAA compliance.
- Submerged Net Cleaning With Suction Collection of Fouling
Low-pressure suction and rotary brushes remove fouling from submerged netting while collecting loosened organisms to prevent damage and spread.
- Multi-Vessel Data Analysis for Hard-to-Change Performance Factors
Aggregating voyage data across multiple vessels reveals how coatings, vessel type, and fuel-saving devices influence performance.
- Marine ICCP Circuit Switching for Low-Salinity Corrosion Protection
Monitored salinity and polarization potential trigger a secondary anode circuit, keeping marine ICCP protection active in freshwater and brackish water.
- Dock Tube Cushion Assembly for Impact-Protected Boat Berthing
A layered dock tube cushion absorbs hull impact and stays secured on metal tubing to prevent boat damage during docking and departure.
- Roll-Sealed Boat Fender for Pump-Free Compact Storage
A flexible shell and reusable roll seal trap air without a pump, letting the boat fender store flat yet still absorb docking impacts.
- Polygonal Floating Offshore Structure for Deep-Water Load Stability
Polygonal columns and large-area pontoons use buoyancy, braces, and dampers to stabilize deep-water offshore power platforms.
- Ship Cofferdam Anticorrosion Machine Using Waste-Heat Drying
Recovered grinding heat warms viscous anticorrosive coating and speeds post-spray drying in automated ship cofferdam treatment.
- Floating Offshore Platform Pontoon Layout for Deep-Water Stability
Outward-protruding pontoons inside a polygonal column layout improve deep-water floating stability while avoiding oversized fixed structures.
- Retractable Hull Mounting Platform for Data Collector Protection
A movable platform retracts into a protective hull cavity, shielding watercraft data collectors from submerged-object impacts.
