Packaging Cover Corner Structure Detachable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging covers are difficult to stack flatly due to their concave design and weak bonding/nailing points, leading to potential deformation or damage during storage.
Innovation Solution
A packaging cover design featuring a baseboard with detachable corner structures, comprising regions with slits, fold lines, and clamping grooves, allowing for perpendicular folding and secure assembly, enabling flat storage and preventing corner damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the packaging cover uses a concave board body design, then it can provide structural coverage, but it becomes difficult to stack flatly and occupies excessive storage space
Solution Approach 1:
The packaging cover is divided into a base board and detachable corner structures. The corner structures can be separated from the base board during storage, allowing the base board to be compressed into a flat state for compact storage, while the corner structures can be stored separately or attached when needed. This segmentation resolves the contradiction by enabling the packaging cover to maintain its functional 3D shape during use while occupying minimal storage space when not in use.
2Ease of manufacture
If bonding or nailing is used to connect corner side walls, then the packaging cover can be assembled, but the bonding/nailing parts become weak and vulnerable to deformation or damage during stacked storage
Solution Approach 1:
The corner structures are extracted as separate detachable components from the base board. Instead of permanently bonding or nailing corners to the base board, the corner structures can be attached and detached as needed. This extraction eliminates the weak bonding/nailing parts that are vulnerable to damage during stacked storage, while still allowing the packaging cover to be assembled when needed. The corner structures can be securely attached during use and then detached for storage without damage.
3Shape
If the packaging cover is designed as a single integrated unit, then it provides complete coverage, but it cannot be flattened for compact storage
Solution Approach 1:
The packaging cover is segmented into a base board and detachable corner structures. During storage, the corner structures can be detached from the base board, allowing the base board to be compressed into a flat state for compact stacking. When needed, the corner structures can be reattached to provide complete coverage. This segmentation enables the packaging cover to transition between providing complete coverage during use and being flattened for compact storage.

AI summary
A packaging cover includes a baseboard and at least one corner structure. The corner structure includes a first region, a second region, a first fold line, a third region, a second fold line, and a fourth region. The first region has a slit, and one of the corners of the baseboard is inserted into the slit. The second region is folded with the first fold line as an axis to be perpendicular to the first region. The third region has a clamping groove. The third region is folded with the second fold line as an axis to be perpendicular to the first region. The fourth region has a fixing part. After the fourth region is folded with the second fold line as an axis, the fourth region is overlapped with the third region, and the fixing part is inserted into the clamping groove.
