Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bulk material delivery and storage systems face inefficiencies such as high capital and operating costs, large physical space requirements, labor-intensive and unsafe manual operations, long discharge times, and unpredictable demand, leading to production stoppages and increased costs due to uncontrollable pneumatic effects and lack of real-time inventory verification.
Innovation Solution
A silo system that enables simultaneous pressurized deposit and discharge of bulk materials with pneumatic isolation between intake and discharge pathways, equipped with material sensors and actuators controlled by a processor for real-time verification and automated confirmation of material deposition, reducing wait times and improving operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If material is deposited into the silo while material is being discharged, then productivity is improved by reducing wait times, but pneumatic interference occurs between intake and discharge pathways
Solution Approach 1:
The silo is divided into two separate chambers: a first chamber for receiving material from the transport container and a second chamber for discharging material to the consignee. This segmentation allows independent pneumatic control of each pathway, eliminating interference between intake and discharge operations while enabling simultaneous filling and emptying.
Solution Approach 2:
A intermediate storage chamber serves as a mediator between the intake pathway and discharge pathway. Material is first deposited into the first chamber, then transferred to the second chamber for discharge. This intermediary structure decouples the pneumatic systems, allowing each to operate independently without affecting the other.
2Ease of operation
If manual operation is used to manage material transfer, then ease of operation is reduced due to labor requirements, but device complexity is minimized
Solution Approach 1:
Material sensors are installed in both chambers to detect material presence and levels. The controller receives feedback from these sensors and automatically controls the pneumatic systems to transfer material from the first chamber to the second chamber when appropriate, eliminating the need for manual intervention while maintaining simple operational logic.
Solution Approach 2:
The silo system is designed to automatically manage its own material transfer operations. The controller autonomously monitors sensor data and activates the pneumatic systems as needed, allowing the system to serve itself without requiring external manual operation for material management.
3Reliability
If large on-site fixed storage capacity is provided, then reliability of supply is improved, but area occupied and capital investment increase
Solution Approach 1:
The system replaces static, large-capacity fixed storage with a dynamic, modular approach. The portable silo can be rapidly deployed and removed, and the dual-chamber design allows continuous operation by transferring material between chambers. This dynamic system provides the same supply reliability with significantly reduced permanent footprint and capital investment.
Solution Approach 2:
The system changes the operational parameters from batch operations (emptying the entire silo at once) to continuous operations (maintaining material levels through simultaneous intake and discharge). This allows the silo to operate continuously without requiring large excess capacity, reducing the needed storage volume while maintaining supply reliability.
4Productivity
If real-time sensor data is used to control actuators, then productivity is improved by enabling simultaneous deposit and discharge, but device complexity increases
Solution Approach 1:
Material sensors in both chambers provide real-time feedback to the controller about material presence and levels. The controller uses this feedback to automatically coordinate the pneumatic systems, enabling simultaneous deposit and discharge operations without complex manual coordination. The feedback mechanism simplifies the control logic despite the increased automation capability.

AI summary
A silo system includes a storage chamber, an intake pathway associated with the chamber, and a discharge pathway associated with the chamber. The system further includes one or more material sensors associated with the chamber, a plurality of actuators, and a controller that is communicatively coupled to the one or more material sensors and to the one or more actuators. The plurality of actuators enable a deposit of additional material from a transport container into the chamber through the intake pathway at least partially simultaneous with a discharge of material from the chamber through the discharge pathway into an operational silo. The material sensors provide indications of the amount of bulk material in the chamber and the controller is configured to control the one or more actuators in response to sensor data from the one or more material sensors to provide for deposit of material simultaneous with discharge of material.
