Detachable Tray-Lid Packaging Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for packaging and displaying products, typically made of paper and cardboard with two open die-cut elements, require complex production cycles and significant machinery investment, leading to inefficiencies in production time, space, and cost.
Innovation Solution
A container formed from a sheet-like element with detachable parts, including a tray and a lid connected via removable association means and creases, allowing for a single linear production cycle and eliminating the need for a lidding machine, using commonly available materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two separate die-cut elements (tray and lid) are used to form the container, then the container can be properly structured with base and packaging, but the production cycle becomes complicated and requires two overlapping sub-cycles
Solution Approach 1:
The patent combines the tray and lid into a single die-cut element with integrated lateral containment elements. This merging eliminates the need for two separate production cycles and the complex overlapping operations required when using separate elements, while still maintaining the functional structure of base and packaging
2Stability of the object's composition
If two separate die-cut elements are used, then the container can be formed, but significant machinery investment is required including lidding machine for closure
Solution Approach 1:
By merging the tray and lid into one die-cut element with integrated lateral containment elements, the patent eliminates the need for separate lidding machinery. The single-element design can be produced and assembled without expensive specialized equipment
Solution Approach 2:
The lateral containment elements are integrally formed as part of the single die-cut element, allowing the container to assemble itself without requiring external lidding machines or complex assembly equipment. The design is self-sufficient in terms of manufacturing infrastructure
3Stability of the object's composition
If two separate die-cut elements are used, then the container can be properly formed, but production time cannot be competitive
Solution Approach 1:
The patent merges tray and lid into a single die-cut element, reducing the container formation process to one production cycle instead of two overlapping cycles. This eliminates time-consuming intermediate steps and significantly accelerates production
Solution Approach 2:
The lateral containment elements are pre-formed as integral parts of the single die-cut element during the initial cutting process. This preliminary formation of containment structures eliminates the need for subsequent assembly operations, thereby reducing total production time
4Stability of the object's composition
If two separate die-cut elements are used, then the container can be formed, but the combination of sub-cycles is not straightforward and simple
Solution Approach 1:
The patent combines tray and lid into one die-cut element with integrated lateral containment elements, transforming a complex two-stage process into a simple single-stage process. The integration makes the production flow straightforward and eliminates coordination challenges between separate sub-cycles
