An apparatus with a hopper and agitator arrangement that includes helical agitation surfaces and multiple outlets, controlled by a circuitry system to agitate and urge bulk material towards outlets, preventing cohesion and enabling efficient conveyance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bulk material is conveyed through a conduit in ambient conditions, then the conveying process is simple, but the conduit becomes blocked due to cohesion caused by temperature and humidity

Engineering Contradiction:
Improveconduit blockage preventionVSAvoidconveying apparatus structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hopper is divided into multiple outlets instead of a single outlet, distributing the bulk material flow across multiple paths. This segmentation prevents material cohesion and blockages by reducing the concentration of material at any single point, thereby improving reliability without requiring complex additional components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The agitator arrangement performs preliminary action by continuously agitating the bulk material in the hopper before it reaches the outlets. This pre-agitation prevents cohesion and ensures material remains in a conveyable state, preventing blockages before they can occur in the conduit

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a single outlet is used for bulk material conveyance, then the apparatus structure is simple, but material cohesion causes blockages and downtime

Engineering Contradiction:
Improveproduction line continuityVSAvoidnumber of outlets and valves
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The single outlet is segmented into multiple outlets, each with its own valve. This allows the system to serve multiple production lines or destinations simultaneously, improving productivity by enabling parallel material distribution while maintaining manageable complexity through modular valve control

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hopper with multiple outlets and valves serves multiple functions: it can supply material to different production lines, different destinations, or operate in different modes (single outlet mode or multiple outlet mode). This multi-functionality improves productivity without proportionally increasing complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If ambient temperature and humidity are not controlled, then energy consumption is low, but bulk material cohesion increases causing blockages

Engineering Contradiction:
Improvematerial flow consistencyVSAvoidenvironmental control energy
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The system uses the natural agitation caused by material accumulation and gravity to create self-service mixing and prevention of cohesion. The multiple outlets and valves allow the system to self-regulate material flow without requiring external environmental control, maintaining reliability while avoiding additional energy consumption for climate control

Inventive Principle:
Principle #25Self-service
