Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If large-capacity trucks with fixed containers are used to deliver bulk particles, then transport capacity is improved, but traceability becomes difficult and the system becomes bulky with maintenance access difficulties

Engineering Contradiction:
Improvebulk particle delivery capacityVSAvoidmaintenance access
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system divides the particle supply into multiple smaller mobile silos instead of one large fixed container. Each silo is independently movable and can be positioned near the energy production equipment, enabling easy maintenance access while collectively providing bulk delivery capacity through coordinated operation of multiple units.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If fixed containers are used for particle storage and delivery, then transport stability is improved, but the system becomes bulky and maintenance access becomes difficult

Engineering Contradiction:
Improveparticle storage stabilityVSAvoidsystem bulkiness
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The system replaces fixed static containers with mobile dynamic silos that can be moved as needed. The mobile silos maintain stable particle storage through proper design features while being dynamically repositionable, reducing overall system bulkiness and improving maintenance accessibility.

Inventive Principle:
Principle #15Dynamics

3Productivity

If particles are handled and transported mechanically, then delivery efficiency is improved, but dust generation increases posing fire risks and causing mass loss

Engineering Contradiction:
Improveparticle delivery efficiencyVSAvoiddust generation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The system uses pneumatic conveying to transport particles from mobile silos to the energy production equipment. This pneumatic method replaces mechanical handling that generates dust, delivering particles efficiently through air flow while containing them within closed conduits, thereby eliminating fire risks and mass loss from dust generation.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Adaptability or versatility

If removable connection units are used for container coupling, then adaptability is improved, but connection reliability may be compromised

Engineering Contradiction:
Improvecontainer interchangeabilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system incorporates preliminary alignment features and pre-positioned connection points on mobile silos that guide and facilitate reliable coupling with the energy production equipment. The removable connection units are designed with built-in alignment mechanisms that ensure proper positioning before connection, maintaining both adaptability for different containers and reliability of the connection.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to an energy production system (1) comprising: an energy production device (8) including a unit (14) for producing energy from a product (2) in the form of particles (4), and a supply device (16); and a container (10) defining an interior space (18). The system comprises at least one removable coupling unit (12) including a first coupling element (20) connected to the energy production device and a complementary second coupling element (22) connected to the container. The coupling unit can occupy a coupled configuration in which the particles can be transferred from the interior space to the supply device, and an uncoupled configuration. When the coupling unit is in the uncoupled configuration, the container can move in relation to the energy production device.
