Foldable File With Convex Edge Asymmetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable files are difficult to unfold due to the edges of multiple panels being separated and overlapped, requiring more time and causing inconvenience.
Innovation Solution
A foldable file design featuring a first panel, a second panel, and a third panel arranged in sequence with specific hinge assemblies, allowing for easy switching between unfolded and folded states, with the second panel located at the bottom layer in the folded state and featuring a convex edge on the third panel to facilitate unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple panels are separated and overlapped together when folded, then the foldable file can be compactly stored in pockets, but it becomes difficult to peel off the edges and unfold quickly
Solution Approach 1:
The patent applies asymmetry by making the side edges of adjacent panels asymmetric in shape. Specifically, one panel has a convex edge while its adjacent panel has a corresponding concave edge, creating a complementary asymmetric pair. This asymmetric design allows the panels to interlock when folded for compact storage, while simultaneously enabling easy identification and separation during unfolding, thus resolving the contradiction between compact folded size and ease of unfolding.
2Productivity
If multiple panels are overlapped together in folded state, then the foldable file is portable, but more time is required to separate the panels during unfolding
Solution Approach 1:
The patent implements preliminary action by pre-forming complementary convex and concave edges on the panels before folding. These pre-designed edge features are prepared in advance during manufacturing, so that when the user needs to unfold the file, the panels can be quickly separated along the pre-defined asymmetric edges without requiring complex manipulation or additional time, thus reducing unfolding time while maintaining portability.
