Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffins made from cardboard materials require complex designs or thick materials to ensure structural integrity, and in calamity situations, there is a need for coffins that can be easily transported and assembled in large numbers.
Innovation Solution
A box manufactured from three parts of sheet material, which are glued together to form a box shape, featuring double folds along edges for enhanced structural integrity and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cardboard coffins use complex designs or thick materials to ensure structural integrity, then strength is improved, but device complexity and material consumption increase
Solution Approach 1:
The coffin is divided into three separate sheet parts that can be manufactured independently and then assembled together. This segmentation allows each part to be optimized for strength while maintaining overall structural integrity, and enables flat packaging for efficient transport and storage.
Solution Approach 2:
The invention uses multiple layers of cardboard material bonded together through folding and gluing to create a composite structure. This composite approach provides enhanced strength and rigidity compared to single-layer cardboard, while still using environmentally friendly materials.
2Strength
If cardboard coffins use complex designs or thick materials to ensure structural integrity, then strength is improved, but manufacturing cost and material consumption increase
Solution Approach 1:
Dividing the coffin into three sheet parts allows for optimized material distribution, using cardboard only where structurally necessary rather than throughout the entire structure, reducing overall material consumption while maintaining strength.
Solution Approach 2:
The invention uses thin sheet material that is folded into three-dimensional structures, creating strength through geometric configuration rather than relying on thick materials. The folding creates rigid edges and corners that provide structural support.
3Productivity
If coffins are manufactured in large numbers for calamity situations, then productivity is improved, but storage space requirements increase
Solution Approach 1:
The coffin is segmented into three flat sheet parts that can be packaged in a compact, space-efficient manner. When needed, these flat parts are quickly assembled into the three-dimensional coffin structure, enabling both efficient storage and rapid deployment in emergency situations.
4Ease of operation
If coffins are designed for easy assembly in emergency situations, then ease of operation is improved, but structural integrity may be compromised
Solution Approach 1:
The sheet parts are pre-cut with fold lines and edges prepared in advance during manufacturing. This preliminary preparation allows the final assembly to be simple and quick while ensuring that all structural elements are properly formed, maintaining strength despite the simplicity of assembly.
Solution Approach 2:
Multiple structural functions are merged into the folding and gluing process itself. The same folding action that creates the three-dimensional shape also creates the bonding surfaces for gluing, combining structural formation and joining operations into a single efficient process.
