Sheet-Like Molded Body With Directional Bending and Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly blocks are not flexible and cannot bend in a particular direction, limiting their application in structures that require flexibility, such as bags.
Innovation Solution
A sheet-like moulded body composed of polygonal plate-like pieces with a connecting portion that allows adjacent pieces to bend and a coupling portion for connecting with other sheet-like bodies, enabling flexible structures like bags to be formed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If assembly blocks use rigid plate-like pieces connected by coupling pieces, then structural stability is improved, but flexibility and bendability deteriorate
Solution Approach 1:
The sheet-like moulded body is divided into multiple polygonal plate-like pieces connected by connecting portions, allowing the structure to be segmented into flexible modular units that can bend at connecting portions while maintaining overall stability
Solution Approach 2:
The connecting portions are designed to enable bending motion between adjacent plate-like pieces, transforming the rigid structure into a dynamic one that can adapt its shape while maintaining structural integrity through the integrated connecting portions
2Ease of operation
If assembly blocks use separate coupling pieces for connection, then ease of assembly is improved, but device complexity increases
Solution Approach 1:
The connecting portions are integrally formed with the plate-like pieces in a single moulding process, merging the connection function into the main body structure and eliminating the need for separate coupling pieces, thereby reducing overall structural complexity
Solution Approach 2:
The connecting portions serve multiple functions: they connect adjacent plate-like pieces, enable bending motion, and are integrally formed with the plate-like pieces themselves, reducing the number of separate components needed while maintaining ease of assembly
