Mineral Mining TRIZ Cases

Real-time sinkage sensing and A-B slurry grouting help deep-sea mining vehicles escape soft seabed trapping by raising local bearing capacity.

Distributed tethered collectors extract seabed nodules selectively while minimizing sediment transport and marine ecosystem disruption.

A balanced, horizontally stacked chamber layout enables long HOHS deployment through a moonpool while reducing tilting and slurry blockages.

Hydraulic circulation collects seabed cobalt crust while limiting sediment diffusion.

Coils apply electromagnetic fields to move dredged soil, reducing pipeline wear and equipment damage caused by high mechanical pressure.

Mud gathering pipe loosens seafloor rare-earth deposits into slurry, isolating extraction to prevent environmental disturbance.

Dual collecting devices on a mining vehicle enable continuous resource gathering without turning, eliminating directional change delays.

A dynamic buoyancy system adjusts water levels in spherical pressure vessels to control the vertical position of a deep-sea mining vehicle.

A submarine exploitation unit uses a high-speed spiral bit to mine hydrates and a drain chamber to dry sediments for efficient recovery.

Freezing water into ice creates buoyancy for lifting nodules, reducing energy costs and environmental impact of deep sea mining.

An alternating stepping deep-sea mining platform reduces energy consumption by relocating via winch-controlled anchors instead of fixed mooring.

A buffer system manages slurry transfer from deep seafloor mining operations using a dedicated structure frame and hydraulic power conversion.
