Solution Overview

Problem

Existing foldable coffins require complex assembly, large storage space, and specific tools, and often necessitate dangerous and impractical top-loading of the deceased body, which is inefficient and hazardous.

Innovation Solution

A foldable coffin made in one piece from rigid materials like cardboard or wood, where the body and lid are directly linked, allowing lateral insertion of the body, with a retention basin to manage bodily fluids, and featuring a folding mechanism that simplifies assembly and transport without specialized tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the coffin is made in one piece from a rigid board, then the structural integrity and ease of manufacture are improved, but the ability to insert the body becomes difficult or dangerous

Engineering Contradiction:

Improvestructural integrityVSAvoidease of body insertion

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The coffin is divided into a rigid body structure and a separate flexible lid that can be folded open. The board is cut and folded to create a lid portion that is hinged to the body, allowing the lid to be opened laterally for easy body insertion while maintaining the structural integrity of the overall coffin structure.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the coffin is made from separate parts, then the ease of assembly and transport is improved, but the manufacturing complexity and storage space requirements increase

Engineering Contradiction:

Improveease of assemblyVSAvoidmanufacturing complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The coffin is constructed as a single integrated piece from one rigid board, with the body and lid directly linked through folding lines. This eliminates the need for separate parts and complex assembly procedures, reducing manufacturing complexity while maintaining ease of assembly and transport.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If the lid is made by folding panels of the plate, then the manufacturing simplicity is improved, but the footprint and storage space requirements increase

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidfootprint

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The coffin is designed to fold flat into a compact configuration for storage and transport, with the lid folded against the body. When not in use, the coffin can be collapsed into a small footprint, similar to how nested dolls store within each other, while maintaining the ability to unfold into the full coffin structure when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Device complexity

If multiple people are required to insert the body from above, then the structural simplicity is improved, but the safety and practicality deteriorate

Engineering Contradiction:

Improvestructural simplicityVSAvoidsafety

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

Instead of inserting the body from above through a top opening, the coffin is designed with a lateral insertion mechanism where the lid folds open to the side, allowing the body to be inserted from the side. This inverts the traditional top-loading approach, improving safety and practicality while maintaining structural simplicity.

Inventive Principle:

Principle #13The other way round (Inversion)
