Retractable Hanger Package Box Assembly for Logistics Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing package box assemblies with hangers protruding from the box bodies create unnecessary dead space during logistics movement and palletizing, leading to reduced loading efficiency, increased logistics and manufacturing costs, and environmental concerns due to non-eco-friendly materials.
Innovation Solution
A package box assembly design that includes a first box with an accommodation portion, a second box partially accommodated within, a hanger disposed in the first space to protrude through an opening in the side wall, an elastic member to push the hanger toward the opening, and a removable sealing member to seal the opening, allowing the hanger to be accommodated and protrude as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hanger protrudes outward from the package box for display purposes, then the display function is improved, but the loading efficiency deteriorates due to increased dead space
Solution Approach 1:
The hanger is designed to be movable between a protruding state (for display) and a retracted state (for compact storage). The elastic member enables the hanger to dynamically change its position, allowing the package box to adapt between display mode and logistics mode, thereby resolving the contradiction between display function and loading efficiency.
Solution Approach 2:
The hanger is nested within the package box when not in use, with the elastic member storing the hanger in a retracted position inside the box body. This nesting approach minimizes the external dimensions of the package box during logistics movement, improving loading efficiency while maintaining the ability to protrude for display when needed.
2Ease of operation
If the hanger protrudes from the package box, then the display function is improved, but the volume of the package box increases leading to higher manufacturing costs
Solution Approach 1:
The hanger's dynamic positioning capability allows the package box to maintain a compact volume during storage and transport while expanding its functional volume when display is required. The elastic member enables this dynamic volume adjustment, resolving the contradiction between display function and package box volume.
3Strength
If the hanger is made of synthetic resin for durability, then the strength is improved, but the eco-friendliness deteriorates
Solution Approach 1:
The material composition of the hanger is changed from synthetic resin to paper-based materials. This parameter change in material type maintains sufficient strength for display functionality while significantly improving eco-friendliness by using biodegradable and recyclable materials, thus resolving the contradiction between strength and eco-friendliness.
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
This design improves loading efficiency by minimizing dead space, reduces manufacturing and logistics costs, and enhances eco-friendliness by allowing the hanger to be made from more sustainable materials.

AI summary
A package box assembly is provided. The package box assembly includes a first box comprising an accommodation portion defined by a plate and a side wall disposed to surround the plate along the periphery of the plate and having a designated height, a second box accommodated in the accommodation portion, a hanger disposed in a first space of the accommodation portion to protrude through an opening formed in the side wall, an elastic member disposed in the first space to press the hanger toward the opening, and a sealing member removably disposed on the side wall to seal the opening. The hanger is accommodated in the first space while being pushed by pressure from the elastic member. In case that the sealing member is removed, the hanger at least partially protrudes to the outside of the first box via the opening by the pushing force of the elastic member.
