Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable container technologies face issues with unauthorized access and dismantling, complex fastening mechanisms, and inefficient storage of empty containers, which compromise safety and efficiency.
Innovation Solution
A foldable container frame with inaccessible hinged elements that require mechanical force for detachment, featuring a polygonal base and upper mount connected by columns with hinged members, including bushings and sliding blocks with guides and stoppers to ensure secure and quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening mechanisms are used to secure longitudinal sidewall bands, then reliable mounting is achieved, but the fastening means becomes complicated and cumbersome
Solution Approach 1:
The container structure is divided into modular components (base structure, top structure, side covers) that can be independently assembled and disassembled. The side covers are further segmented into lower and top sections that can be pivotally moved relative to each other, enabling simplified fastening mechanisms while maintaining mounting reliability.
Solution Approach 2:
Instead of using complex external fastening mechanisms to secure the container, the invention uses internal pivotal connections and hinge arrangements that allow the structure to self-secure through its own geometry. The central hinge arrangement enables the top section frame to pivotally move relative to the lower section frame, creating a self-locking mechanism that simplifies the fastening system while maintaining reliability.
2Ease of operation
If simple fastening mechanisms are used for container assembly, then ease of assembly is improved, but unauthorized access and dismantling become possible
Solution Approach 1:
The container employs dynamic pivotal connections and hinge arrangements that allow for easy assembly and disassembly through controlled movement. The lower section frame and top section frame are connected via pivotal joints that enable smooth assembly operations while maintaining security through the geometric interlocking of the structures.
Solution Approach 2:
The hinged member is nested within the column structure, with the hinge pin positioned inside the column's hollow section. This nesting arrangement protects the critical hinge components from unauthorized access while maintaining ease of assembly through the integrated design. The hinge pin is accessible only through the open end of the column during assembly operations.
3Volume of moving object
If foldable container design is implemented, then storage space requirement is reduced, but complex hinge arrangements and fastening mechanisms are required
Solution Approach 1:
The container is segmented into collapsible sections (lower section frame, top section frame, side covers) that can be pivotally moved relative to each other. This segmentation enables the container to collapse into a compact configuration for storage while using relatively simple pivotal connections rather than complex mechanisms.
Solution Approach 2:
The pivotal connections and hinge arrangements serve multiple functions: they enable easy assembly and disassembly, allow the container to collapse for compact storage, and provide structural support. The central hinge arrangement simultaneously facilitates the pivotal movement of the top section frame and maintains the structural integrity of the container during both expanded and collapsed states.
4Ease of operation
If fastening means are made accessible for easy assembly, then ease of operation is improved, but safety against unauthorized access deteriorates
Solution Approach 1:
The hinge pin and other critical fastening components are nested within the hollow sections of the columns. This nesting protects the fastening means from unauthorized access while maintaining ease of operation during legitimate assembly. The hinge pin can be accessed through the open end of the column during assembly but is protected when the container is closed and in use.
