Stackable Packing Box With Individual Sliding Lids And Breakable Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packing boxes with multiple partitions and a single sliding lid cannot access individual compartments without opening adjacent compartments, making it difficult to remove items from a single compartment without emptying paired compartments.
Innovation Solution
Designing packing boxes with single partitions arranged in succession, allowing each compartment to be closed by an individual sliding lid, and connecting them via a connection cam and film hinge for swiveling and locking, enabling independent access to compartments and compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a packing box has a single sliding lid with multiple paired compartments, then the structure is simple and manufacturing is easy, but individual compartments cannot be accessed without opening adjacent compartments
Solution Approach 1:
The packing box is divided into multiple independent box rows, each with its own sliding lid. The interior partitioning is configured so that each box row contains single compartments arranged in succession rather than paired compartments. This segmentation allows each sliding lid to control access to its specific box row and compartments independently, resolving the contradiction between individual accessibility and structural simplicity.
2Strength
If multiple packing boxes are joined rigidly together, then structural strength is improved, but flexibility for storage and dispensing is reduced
Solution Approach 1:
The connection between packing boxes transitions from a static rigid structure to a dynamic system. A tear-off cam mechanism is introduced that initially provides a rigid connection for strength, but can be activated to break the rigid connection and allow the boxes to swivel about a film hinge. This enables the system to adapt between rigid (for strength) and flexible (for storage and dispensing) configurations as needed.
Solution Approach 2:
When the rigid connection is broken, the packing boxes can be swiveled and nested together in a compact stacked configuration. The boxes fit together in a space-efficient manner, allowing multiple boxes to be stored vertically in automatic dispensing systems or during transportation, thereby improving adaptability without compromising the structural strength when in the expanded configuration.
3Productivity
If packing boxes are designed for easy separation, then productivity is improved, but structural stability during handling is reduced
Solution Approach 1:
The tear-off cam is pre-positioned in a locked state that provides stable stacking during handling and transportation. The cam mechanism is designed so that the locked position maintains structural stability, while the unlocking action (pulling the cam) is simple and requires minimal force. This preliminary stable configuration ensures stack stability during normal handling, while enabling rapid separation when needed for dispensing or reconfiguration.

AI summary
A packing box (1, 2) with a bottom wall (15) and adjoining side and end walls (3-8) and at least one closure lid (9, 10) is provided. Several roughly identical packing boxes (1, 2) may be joined to each other at their mutually adjacent side walls (4, 5) and may swivel about a breakable film hinge (17) and at least one breakable connection cam (14) spanning the film hinge which is arranged between the mutually adjoining side walls (4, 5).
