Solution Approach 1:

A robotic device equipped with sensors and manipulation tools serves as an intermediary between human operators and bulk stored granular materials. The robot performs dangerous tasks such as slope adjustment, material agitation, and inspection, eliminating direct human exposure to hazards like avalanches, entrapments, and dust explosions while maintaining operational flexibility through remote or autonomous control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces human mechanical operations with an automated robotic system that uses sensors, motors, and control algorithms to perform tasks. The robotic device substitutes human physical intervention with automated mechanical and electronic systems, reducing safety risks while maintaining the ability to manipulate bulk materials effectively.

Inventive Principle:

2Ease of operation

If human workers enter bulk stores to manage granular materials, then direct operational control is achieved, but exposure to harmful environmental conditions increases

Engineering Contradiction:
ImproveDirect operational controlVSAvoidEnvironmental hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The robotic device acts as an intermediary that operates within the hazardous bulk store environment while human operators remain outside. The robot is equipped with sensors and communication systems that enable direct operational control through remote interfaces, allowing humans to maintain full control without exposure to dust, heat, confined spaces, and other environmental hazards.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The robotic system creates a virtual copy of the bulk store environment through sensors and cameras, transmitting real-time data to remote operators. This allows operators to monitor and control operations as if present in the environment, maintaining direct operational control while staying in safe, controlled conditions outside the bulk store.

Inventive Principle:
Principle #26Copying

3Volume of stationary object

If steep slopes form in bulk stored granular materials, then storage capacity is maximized, but stability decreases and avalanche risk increases

Engineering Contradiction:
ImproveStorage capacityVSAvoidSlope stability
Core Design Contradiction:
Volume of stationary objectVSStability of the object's composition

Solution Approach 1:

The robotic device performs preliminary slope adjustment operations before avalanches can occur. By continuously monitoring slope angles and proactively redistributing material to maintain stable angles, the system prevents instability from developing while maximizing storage capacity. The robot agitates and redistributes granular material in advance to maintain preventive stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements periodic slope inspection and adjustment operations. The robotic device regularly traverses the bulk material, measures slope angles using sensors, and performs agitation or redistribution when thresholds are approached. This periodic maintenance ensures stable slopes are maintained over time, balancing storage capacity with safety.

Inventive Principle:
Principle #19Periodic action

AI summary

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot via the auger-based drive system. The processor obtains a first measurement of an angle of slope of a portion of piled granular material in a bulk store. In response to the first measurement satisfying a first condition, the robot traverses the portion of piled granular material to incite sediment gravity flow in the portion of piled granular material by disruption of viscosity of the portion of piled granular material through agitation of the portion of piled granular material by auger rotation of the auger-based drive system. The processor obtains a second measurement of the angle of slope of the portion of piled granular material. In response to the second measurement satisfying a second condition, the robot ceases traversal of the portion of piled granular material.
