Cardboard Box Hanger With Disk Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanger bars made of plastic or metal for boxes face difficulties in shipping and disposal, and struggle to securely couple with the box walls, especially when used in cardboard boxes for moving or clothing transport.
Innovation Solution
A tubular hanger body with disk-like locking elements and retention means that straddle the box walls, allowing easy insertion and secure locking within vertical slots, using materials like recycled cardboard or plastic, minimizing external protrusion and enabling easy assembly and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a monolithic hanger bar made of plastic or metal is used, then the hanger has sufficient strength, but it creates difficulties in shipping and disposal
Solution Approach 1:
The hanger is divided into multiple separate components: a tubular body, disk-like locking elements, and retention means. These components can be manufactured separately from different materials (cardboard, plastic, metal) and assembled within the box, making shipping and disposal easier while maintaining structural strength through proper component design and material selection
2Ease of operation
If a conventional hanger bar is used, then it provides basic hanging function, but it has difficulties in coupling to the walls of the box
Solution Approach 1:
The coupling function is segmented into multiple components: the tubular body provides structural support, disk-like locking elements engage with the box walls through vertical slots, and retention means secure the assembly. This segmentation allows each component to be optimized for its specific function, improving both ease of coupling and reliability
Solution Approach 2:
The disk-like locking elements act as intermediaries between the tubular body and the box walls. These elements straddle the side walls and lock the tubular body in place, providing a reliable coupling mechanism that is easier to install than conventional monolithic hangers
3Reliability
If locking means with disk-like elements are added to the hanger, then the coupling reliability improves, but the device complexity increases
Solution Approach 1:
The locking mechanism is segmented into simple, flat disk-like elements that can be easily manufactured and assembled. These disks engage with vertical slots in the box walls, providing reliable locking without requiring complex mechanisms. The segmentation allows for easy assembly and disassembly while maintaining high reliability
