Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fixed vertical silos are used for storage, then storage capacity is sufficient, but setup time becomes extensive and portability is reduced
Solution Approach 1:
The storage system is divided into multiple mobile storage modules that can be individually transported and assembled. Each module is a self-contained unit that can be moved independently, allowing the system to be segmented for easier transport and rapid assembly on-site, eliminating the need for extensive setup of fixed silos while maintaining adequate storage capacity through modular expansion
Solution Approach 2:
The storage system transitions from a fixed, static configuration to a dynamic, mobile configuration. The mobile storage modules are designed to be movable and reconfigurable, enabling rapid deployment and teardown. The system can be dynamically assembled from transported modules and disassembled for relocation, providing both adequate storage capacity and rapid setup/teardown capability
2Quantity of substance
If fixed vertical silos are used for storage, then storage capacity is sufficient, but portability and adaptability are reduced
Solution Approach 1:
The storage system is segmented into transportable mobile modules that can be moved to different locations. Each module is designed as an independent unit that can be transported via standard transportation methods, allowing the system to be relocated and adapted to different project sites while maintaining adequate storage capacity through the ability to add or remove modules
Solution Approach 2:
The mobile storage modules are designed with universal features that enable them to function in multiple configurations and locations. The modules can be used for various granular materials, transported by different methods, and assembled in different arrangements to meet varying storage requirements, providing both adequate capacity and high portability/adaptability
3Quantity of substance
If large storage facilities are constructed, then storage capacity is sufficient, but cost increases
Solution Approach 1:
The storage system uses standardized mobile modules that can be manufactured independently and assembled on-site. This segmentation allows for economies of scale in module production while avoiding the high costs of constructing large fixed facilities. The modular approach enables storage capacity to be achieved through assembly of multiple smaller, cost-effective units rather than building one large expensive structure
Solution Approach 2:
The mobile storage modules are designed as temporary, relocatable units rather than permanent fixed structures. They can be manufactured at lower cost using simpler materials and construction methods appropriate for temporary deployment, then moved or dismantled after use. This approach provides adequate storage capacity at reduced cost compared to permanent facilities
4Productivity
If dry-bulk blower is used for filling, then filling capability is achieved, but dust creation and noise increase
Solution Approach 1:
The dry-bulk blower system, which generates harmful dust and noise, is extracted or eliminated from the filling process. Instead, the system uses alternative filling methods such as gravity flow, conveyor systems, or enclosed transfer mechanisms that do not require high-velocity air blowing. This maintains filling capability while removing the source of dust and noise pollution

AI summary
A method and system for handling granular material, such as proppant used in hydraulic fracturing in well drilling, is provided. In an operational configuration, a delivery module having conveyors receives and conveys granular material to a delivery location, and one or more mobile storage modules receive, hold and dispense granular material downward to the delivery module. The mobile storage modules comprise a raised, angular container portion for holding granular material. Each mobile storage module may comprise a rock-over chassis for support against ground. A remote control module provides centralized, remote control of the system. Mobile support unit modules may also be provided as a remotely controlled vehicle capable of providing power, control, heating, and the like to other modules. Mobile in-feed elevator modules may also be provided as a remotely controlled vehicle for feeding granular material to mobile storage modules. In a transportation configuration, each module is separately transportable.
