Foldable Cargo Container with Lead Screw Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo containers require lengthy assembly processes due to separate lower and side face portions, leading to increased storage and transportation challenges, particularly in countries with predominant import trade where many containers remain unused after unloading.
Innovation Solution
A cargo container design featuring a hexahedral frame with lead screws and guide brackets that allow for easy folding and fixing modes, reducing volume and enabling efficient stacking, while also enhancing safety through protruding parts and correction mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lower face and side face portions are provided separate as in existing foldable containers, then the container can be folded for storage, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent merges the lower face portion and side face portions into a single integrated container body structure. The side face portions are directly connected to the lower face portion without separate assembly requirements, eliminating the complex multi-step assembly process while maintaining the foldable functionality for storage.
2Volume of moving object
If the container maintains its full volume after unloading cargo, then cargo capacity is maximized, but storage and transportation of empty containers becomes difficult
Solution Approach 1:
The patent implements a dynamic volume container where the side face portions can be folded inward along folding lines. This allows the container to transition from a full-volume state during cargo loading to a compressed state for storage and transportation, optimizing both cargo capacity and storage efficiency.
3Ease of operation
If the container is designed to be foldable for easy storage, then storage efficiency improves, but the structural strength and stability may be compromised
Solution Approach 1:
The patent segments the side face portions into foldable sections connected by folding lines, allowing the container to be divided into manageable segments for storage while maintaining structural integrity during use. The segmented design enables folding without compromising the overall strength when the container is in its operational state.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces transportation costs and time, improves safety by preventing external forces from dislodging the container, and simplifies storage by allowing for single-operation, integrated folding, thus addressing the inefficiencies of traditional foldable containers.
Implementation Method 1
a lead screw (3000) attached to at least one of the lower frames (1300)
Implementation Method 2
a guide bracket (4000) penetrated by the lead screw (3000), and moving in a reciprocating motion by rotation of the lead screw (3000)

AI summary
A cargo container is provided. The cargo container includes a frame part, a panel part, a plurality of lead screws and a plurality of guide brackets, so that the cargo container may be operated in a fixing mode or a folding mode according to loading or unloading of cargo. Thus, the volume in the folding mode may be reduced, and transport with stacked may be facilitated, so that a highly efficient cargo container may be provided that is easy to store and transport.
