Foldable Carrying Box Hinge and Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carrying boxes with large volumes incur unnecessary transportation and storage costs when not able to be reduced in size, leading to increased logistics costs.
Innovation Solution
A carrying box with a hinge structure that allows for folding, utilizing a latch assembly to maintain the reduced volume and prevent unintentional unfolding, comprising a first and second side wall, connection walls, and a latch assembly with a lever and catcher mechanism to secure the folded position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the carrying box is made with a large inner space to accommodate large cargoes, then the cargo capacity is improved, but the transportation and storage costs increase when the box is empty
Solution Approach 1:
The carrying box employs a foldable structure with hinge connections between side walls and connection walls, allowing the box to dynamically change its volume between a large state during cargo transport and a compact folded state during return trips and storage, thereby eliminating the waste of transporting empty large-volume boxes
Solution Approach 2:
The box structure is divided into modular components including side walls, connection walls, and hinge joints that can be folded relative to each other, enabling the box to be collapsed into a compact form for efficient storage and return transportation
2Volume of moving object
If the carrying box is made with a large inner space to accommodate large cargoes, then the cargo capacity is improved, but the storage costs increase when the box is unused
Solution Approach 1:
The carrying box employs a foldable structure with hinge connections between side walls and connection walls, allowing the box to dynamically change its volume between a large state during cargo transport and a compact folded state during return trips and storage, thereby eliminating the waste of transporting empty large-volume boxes
Solution Approach 2:
The box structure is divided into modular components including side walls, connection walls, and hinge joints that can be folded relative to each other, enabling the box to be collapsed into a compact form for efficient storage and return transportation
3Stability of the object's composition
If the latch assembly is added to maintain the reduced volume, then the volume reduction is secured, but the device complexity increases
Solution Approach 1:
The latch assembly is designed to automatically engage when the connection walls are folded to overlap, utilizing the natural movement of the folding action itself to trigger the latching mechanism, thereby securing the folded position without requiring additional manual operations or complex control systems
Solution Approach 2:
The latch assembly acts as an intermediary mechanism between the folding action and the final locked position, using a simple lever and catcher structure to translate the folding movement into a stable locked state that prevents unintentional unfolding
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 carrying box can significantly reduce logistics costs by minimizing its volume during retrieval and storage, while preventing damage from unintentional unfolding.
Implementation Method 1
a central elastic member configured to pivotally hinge the first central hinge housing and the second central hinge housing to each other
Implementation Method 2
the latch includes a lever and a catcher that are pivotally configured to fix the hang bar when the hang bar is inserted into the latch
