Collapsible Box Lid Assembly Mitered Corners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional storage boxes lack an aesthetically pleasing design while maintaining robustness and ease of assembly, with smooth edges and corners, and the ability to be easily printed upon, while also being collapsible for space conservation.
Innovation Solution
A collapsible box and lid assembly featuring mitered edges and corners, locking flaps, and handle openings, allowing for easy assembly and disassembly, with a design that enables printing and aesthetic appeal, constructed from corrugated cardboard with specific fold lines and perforations for efficient folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional storage boxes are made robust and capable of holding heavy loads, then strength is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The box is divided into a box portion and a lid portion that can be assembled separately. The lid portion includes intermediate flaps that can be independently positioned to create smooth edges and corners, allowing the aesthetic features to be added without compromising the robustness of the main box structure.
Solution Approach 2:
The intermediate flaps are positioned specifically at the edges and corners where aesthetic appearance is most important. These local additions of material create smooth surfaces and rounded corners while the main box walls maintain their robust, heavy-load-capable structure.
2Volume of moving object
If boxes are made collapsible for space conservation, then volume is reduced, but assembly complexity increases
Solution Approach 1:
The collapsible design is achieved by segmenting the box into a box portion and a lid portion with intermediate flaps. This segmentation allows the box to be collapsed into a flat configuration for space conservation while the fold lines and perforations provide clear assembly guidance, reducing the actual assembly complexity despite the segmented structure.
3Shape
If boxes are designed with smooth edges and corners for aesthetic appeal, then appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The intermediate flaps are pre-positioned and secured to the lid portion before final assembly. This preliminary action creates the smooth edges and corners in advance, allowing the main box structure to be manufactured separately with standard processes, thus reducing overall manufacturing complexity while achieving the desired aesthetic appearance.
4Ease of operation
If boxes are designed for easy assembly by end users, then ease of operation is improved, but structural robustness may deteriorate
Solution Approach 1:
The box is segmented into a box portion and a lid portion that can be assembled separately by the end user. The intermediate flaps are designed as simple, self-aligning components that easily attach to the lid, providing easy assembly while the main box walls maintain their robust construction capable of holding heavy loads.

AI summary
A collapsible cardboard box and lid. The box sides each comprise an outer face and an inner face flap connected by a fold-over region. Mitered edges of adjacent fold-over regions align to define mitered corners of the box opening periphery. Intermediate side flaps connected to the outer shell bottom are sandwiched between the side outer faces and inner face flaps, and a locking flap connected to one of the sides defines an interior bottom. The lid top face is connected to a first set of outer side faces connected by a fold-over region to inner side faces. One inner side face is connected to a top locking liner flap that extends to an abutment with the inner side face to define the lid interior. A second set of outer side faces connects to intermediate flaps sandwiched between the first set of outer side faces and inner side faces.
