Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffins made of wood, wood-base materials, or glass allow decomposition substances to permeate into soil and groundwater, and they often have difficulties with lifting heavy lids and insufficient rigidity.
Innovation Solution
A coffin design using natural stone and glass fibre mat materials with a tubular element and slat rectangular frames, equipped with gas springs to facilitate easy lid lifting and ensure long-term tightness and stability, featuring a combination of natural stone, wood-base materials, and glass fibre mat for durability and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a coffin is made of wood, wood-base materials, or glass, then it provides basic containment functionality, but decomposition substances can permeate into soil and groundwater
Solution Approach 1:
The coffin combines natural stone for the outer casing with a glass fibre mat inner lining and sealing masses, creating a composite structure that provides both mechanical strength and impermeability. The natural stone casing provides structural integrity while the glass fibre mat and sealing masses prevent decomposition substances from permeating into the environment.
Solution Approach 2:
The patent uses a glass fibre mat lining that acts as a flexible yet impermeable barrier between the corpse and the outer stone casing. This thin film structure effectively seals the interior space, preventing harmful substances from penetrating through while maintaining the overall structural form.
2Strength
If the coffin lid is made of heavy natural stone, then it provides durability and aesthetic value, but it becomes difficult to lift and operate
Solution Approach 1:
The patent incorporates counterweights that balance the heavy stone lid, reducing the effective weight that needs to be lifted. These counterweights are integrated into the coffin structure and work with the hinge mechanism to offset the gravitational force on the lid, making it easier to open and close despite the heavy natural stone material.
Solution Approach 2:
The patent replaces the simple mechanical hinge system with a more complex mechanism that includes gas springs or hydraulic dampers. These devices provide assisted movement, reducing the manual force required to lift and operate the heavy stone lid while maintaining secure closure when closed.
3Adaptability or versatility
If the inner cuboidal element is made of glass fibre mat, then it provides flexibility and sealing, but it has insufficient rigidity
Solution Approach 1:
The patent creates a composite structure where the glass fibre mat inner lining is combined with the rigid natural stone outer casing. The glass fibre mat provides flexibility and conformability to seal around the corpse, while the natural stone casing provides the necessary rigidity and structural support. The two materials work together to compensate for each other's weaknesses.
Solution Approach 2:
The patent uses a nested structure where the glass fibre mat lining is placed inside the natural stone casing. The inner glass fibre mat layer provides flexibility and sealing, while the outer stone layer provides rigidity. This nested arrangement allows each material to perform its optimal function without compromising the other.
