Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing connection systems for inner and outer coffins are cumbersome, making it difficult to couple and decouple them, especially for transporting the inner coffin with the outer coffin.

Innovation Solution

A connection system featuring recesses in the inner coffin walls for receiving support pins, which can be easily aligned and secured, allowing for secure and simple coupling and decoupling, with reinforced walls and displaceable support pins for stable positioning and easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional connection system with a load bearing frame construction is used, then the inner coffin can be securely held in the outer coffin, but the inner coffin must be removed through a cumbersome construction

Engineering Contradiction:

Improvesecure couplingVSAvoidremoval of inner coffin

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connection system is divided into separate components: support pins on the outer coffin and corresponding recesses in the inner coffin. This segmentation allows the inner coffin to be easily coupled by inserting pins into recesses and decoupled by removing pins, eliminating the need for cumbersome frame constructions while maintaining secure coupling during transport

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection functionality is extracted from a complex frame construction and simplified to discrete support pins that can be independently positioned and removed. The pins are taken out from a continuous frame structure, allowing selective engagement at specific points (recesses) on the inner coffin, enabling easy coupling and decoupling operations

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If the outer coffin determines the appearance while the inner coffin is reused, then the outer coffin can be repeatedly used, but the connection system becomes complex

Engineering Contradiction:

Improvereuse of outer coffinVSAvoidconnection system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support pins and recesses create a universal connection interface that works with any inner coffin placed in the outer coffin. The pins can engage with recesses at different positions depending on the inner coffin's requirements, allowing the outer coffin to be repeatedly used with different inner coffins without requiring a complex, customized connection system for each combination

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connection system is made dynamic through displaceable support pins that can be moved to different positions along the outer coffin's length. This dynamic positioning capability allows the connection points to be adjusted based on the specific inner coffin being used, providing versatility for repeated use while keeping the connection mechanism itself simple and standardized

Inventive Principle:

Principle #15Dynamics

AI summary

A connection system for an inner coffin and an outer coffin, the inner coffin comprising a bottom and side walls extending from the bottom, wherein the outer coffin comprises a load bearing frame construction near the bottom of the inner coffin. The load bearing frame construction comprises movable support pins embodied for insertion in openings that are provided in an inner coffin's wall near the bottom thereof, for carrying the inner coffin.
