Multi-Chamber Container Filling with Segmented Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Loose bulk materials, such as dry premix concrete, are not suited for storage in porous containers due to susceptibility to moisture and chemical reactivity, which can lead to premature hardening or spoilage.
Innovation Solution
A filling machine that fills multi-chamber containers with separate bulk materials, using elevated hoppers and actuatable members to dispense materials into isolated chambers, preventing exposure to moisture and contaminants, and includes a data recorder for measuring and recording the quantity of each material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bulk materials are stored in porous containers, then storage is simplified and cost-effective, but the materials are exposed to moisture and contaminants causing spoilage or premature hardening
Solution Approach 1:
The container is divided into multiple sealed chambers that isolate bulk materials from the external environment. Each chamber acts as an independent storage compartment, preventing moisture and contaminant exposure while maintaining storage functionality. This segmentation resolves the contradiction by providing protection without sacrificing storage simplicity.
Solution Approach 2:
A liner or barrier material is introduced as an intermediary between the bulk material and the porous container walls. This intermediary layer blocks moisture and contaminants from reaching the material while allowing the container to maintain its porous structure for ventilation and structural integrity.
2Volume of stationary object
If multiple bulk materials are stored together in a single container, then storage space is maximized, but cross-contamination and chemical reactions occur between materials
Solution Approach 1:
The container is divided into multiple sealed chambers that physically separate different bulk materials. Each chamber independently stores a specific material, preventing cross-contamination and chemical reactions while maximizing the use of the entire container volume through efficient spatial arrangement.
Solution Approach 2:
Each chamber within the container is designed with specific local properties (sealing, isolation) tailored to the storage requirements of the particular material it contains. This allows different materials to be stored simultaneously in the same container without interaction, resolving the contradiction between space utilization and contamination prevention.
3Reliability
If separate filling processes are used for each bulk material, then material isolation is ensured, but filling time and operational complexity increase
Solution Approach 1:
Multiple bulk materials are pre-loaded into separate elevated hoppers before the filling operation begins. During filling, materials are simultaneously dispensed from these pre-positioned hoppers into their respective chambers, eliminating sequential handling time while maintaining strict material isolation through dedicated dispensing pathways.
Solution Approach 2:
The filling operation merges multiple material dispensing streams into a single coordinated process. While materials remain isolated in separate chambers, their filling occurs simultaneously through integrated control mechanisms, reducing total filling time without compromising material separation.
4Device complexity
If manual measurement and recording of bulk material quantities are used, then equipment complexity is minimized, but measurement precision and record-keeping accuracy decrease
Solution Approach 1:
Manual measurement and recording mechanisms are replaced with automated electronic sensors and data recording systems. These systems continuously monitor material quantities during filling and automatically record data, providing precise measurements without significantly increasing operational complexity. The electronic system integrates seamlessly with the existing filling mechanism.
Solution Approach 2:
Measurement devices provide real-time feedback on material quantities being filled, allowing for precise control and automatic adjustment of filling rates. This feedback mechanism ensures accurate measurement and recording while maintaining relatively simple equipment through intelligent control algorithms rather than complex mechanical systems.

AI summary
An apparatus and method are provided for filling multi-chamber containers with different loose bulk materials. The apparatus and method may be particularly well-suited to packaging at least one bulk material, which is susceptible to water, chemicals, or other contaminants, with at least one other bulk material. The apparatus is a machine that includes separate hoppers for handling the separate bulk materials, and directs the separate bulk materials into different chambers of a multi-chamber container, which is then transported away from the machine for storage or use. The machine may include one or more movable hoppers supported on tracks, for moving the bulk materials to the hoppers that direct the bulk materials into different chambers of the multi-chamber container. A controller and data logger may be provided to control the apparatus and record the quantity and/or weight of the contents of each multi-chamber container.
