Solution Overview
Problem
Existing containers for transporting bulk particulate materials are inefficient, requiring significant manual labor and having limited volume, which complicates the filling and handling process.
Innovation Solution
A packaging system utilizing a unitary transporter base and a slip frame former to form a transportable container, where a flexible bag is filled with bulk goods and secured with a stretch wrapping device or heat shrink film, allowing for efficient shaping and securing of the contents, reducing manual labor and optimizing space during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional containers are used for transporting bulk particulate materials, then the containers can be manufactured with standard designs, but they require significant manual labor for filling and handling and have limited volume
Solution Approach 1:
The patent employs a dynamic cage structure that moves between an open position for filling and a closed packing position for securing the bulk material. The cage can be positioned at different heights and orientations, allowing automated filling operations and efficient handling by lifting devices, thereby reducing manual labor while maintaining standard container manufacturing capabilities
Solution Approach 2:
The cage acts as an intermediary device between the bulk material source and the container. It facilitates automated filling by positioning and securing the material, and serves as a handle for automated lifting and transport, eliminating the need for manual filling and handling operations
2Volume of stationary object
If traditional containers are used for transporting bulk particulate materials, then the containers can be produced with conventional methods, but they do not have a very large volume
Solution Approach 1:
The container system is segmented into multiple functional components: the container body, the movable cage, and the positioning mechanism. This segmentation allows each component to be optimized independently - the container body can be manufactured as a standard large-volume unit, while the cage provides the necessary structural complexity only when needed for packing and securing, not for the basic container formation
3Reliability
If a cage is used to surround and secure bulk goods in a container, then the goods are securely contained, but the cage structure adds complexity to the packaging system
Solution Approach 1:
The cage is designed as a multi-functional device that serves multiple purposes: it acts as a filling guide, a securing mechanism, a positioning tool for lifting devices, and a protective barrier during transport. By consolidating these functions into a single movable structure rather than requiring separate components for each function, the system achieves reliable secure containment without proportionally increasing overall system complexity

AI summary
The present invention relates to a method of producing a transportable container for bulk goods which seeks to form a transportable container for bulk goods with a transporter base (22) having a periphery and a wall extending upwardly from the periphery of the transporter base (22) to wall end with a radially extending lip, comprising the steps of: placing the transporter base (22)below a feed source (50); placing a bag (48) with an open top and a closed base between the transporter base (22) and the feed source (50), filling the bag (48), monitoring a fill level of the bulk goods in the bag (48) while filling the bag (48); disposing a portion of stretch wrap (38) around the wall and the radially extending lip of the transporter base (22), vertically moving the transporter base (22) relative to the feed source (50) and disposing additional portions of stretch wrap (38) around the bag (48).
