Foldable Case With Nested Flaps For Adhesive-Free Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable paper cases are not collapsible between an open and closed position without disassembling into an unfolded configuration, limiting their use in cooking or baking applications.
Innovation Solution
A foldable case design featuring a sheet of material with specific folding lines and connecting flaps that allows for easy conversion between open and closed positions, enabling single folding and unfolding actions for storage and use, made from heat-resistant paper suitable for cooking or baking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional foldable paper cases are designed to be folded, then they can be collapsed to an unfolded sheet, but they require adhesive means to return to folded configuration and cannot maintain closed position
Solution Approach 1:
The case is divided into multiple portions (first, second, third, fourth portions) connected by folding lines, allowing each portion to be independently positioned while maintaining overall structural integrity. This segmentation enables the case to collapse into a compact closed position without requiring adhesives.
Solution Approach 2:
The first and second portions are positioned within or alongside the third and fourth portions when collapsed, creating a nested configuration. This nesting allows the case to achieve a compact closed state while maintaining structural stability without adhesive means.
2Ease of manufacture
If foldable case uses simple folding without connecting flaps, then assembly is easier, but structural stability and ability to maintain closed position deteriorates
Solution Approach 1:
The connecting flaps merge the first and second portions with the third and fourth portions through adhesive bonding. This merging creates a stable closed configuration while maintaining relatively simple assembly processes.
Solution Approach 2:
The connecting flaps are integrated into the case structure itself, allowing the case to maintain its closed configuration through its own structural features rather than requiring separate fastening mechanisms. The flaps serve both as connection elements and as part of the case body.
3Adaptability or versatility
If conventional foldable case is designed for storage, then it can be collapsed, but it cannot be used for cooking or baking applications
Solution Approach 1:
The case is designed to maintain specific geometric parameters and structural relationships when collapsed, creating a configuration suitable for cooking and baking applications. The folding lines and connecting flaps work together to provide the necessary structural integrity for culinary use.

AI summary
A foldable case and method of making same are disclosed. The foldable case is collapsible between a closed position and an open position without needing to re-fold the sheet of material. The foldable case is made of a sheet of material. The sheet of material has a central portion, opposing first and second portions, and opposing third and fourth portions. First and second portions adjoin a length of respective top and bottom edges of the central portion. Third and fourth portions adjoin a length of respective left and right edges of central portion. A number of folding lines are provided on the sheet of material. The foldable case can be made by folding along the folding lines and adhering first and second portions to the third and fourth portions so as to form a case in the folded configuration.
