Coffin With Active Gas Exchange For Accelerated Bone Decomposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current funeral methods, such as burial and cremation, face challenges in land usage and public acceptance, particularly regarding cremation. There is a need for an efficient and environmentally friendly method to decompose a body into bones and process them further into bone ashes.
Innovation Solution
A coffin system that incorporates an air intake and exhaust system, utilizing pumps controlled by IoT sensors to monitor gas concentrations, which accelerates body decomposition by supplying oxygen. The system includes a waterproof bag, humidity sensors, and specific gas sensors to manage the decomposition process efficiently. After decomposition, the bones can be sterilized, cleaned, and dried without opening the coffin, and treated to reduce environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional burial method is used, then body decomposition occurs naturally, but large area of land is occupied
Solution Approach 1:
The patent changes the parameters of the decomposition environment by controlling oxygen concentration, temperature, and humidity within the coffin. An air supply system provides oxygen-enriched air, while sensors monitor and adjust environmental parameters to accelerate decomposition, thereby reducing land area requirements while maintaining efficient decomposition rates.
Solution Approach 2:
The patent replaces natural, passive burial decomposition with an active, controlled system using mechanical air supply pumps, electronic sensors, and automated control mechanisms. This substitution enables accelerated decomposition in a compact container, eliminating the need for large burial grounds.
2Area of stationary object
If cremation method is used, then land occupation is reduced, but public acceptance is difficult due to fear and cultural reasons
Solution Approach 1:
The patent segments the death processing into two distinct phases: decomposition phase (accelerated bone formation) and cremation phase (optional bone-to-ash conversion). This segmentation allows families to choose only the cremation step if desired, separating the controversial element from the acceptable decomposition process, thereby improving public acceptance while maintaining land efficiency.
Solution Approach 2:
The system provides transparent, controllable decomposition that gives families confidence in the process, reducing fear associated with unknown outcomes. The automated monitoring and control systems ensure proper decomposition before any cremation, making the process more acceptable to the public.
3Device complexity
If natural decomposition is allowed without intervention, then no additional equipment is needed, but decomposition time is extended
Solution Approach 1:
The system actively modifies decomposition parameters by supplying oxygen-enriched air, controlling temperature, and managing humidity levels. These parameter changes accelerate the decomposition process significantly compared to natural conditions, reducing time requirements despite the added equipment complexity.
4Object-generated harmful factors
If the coffin is kept sealed during decomposition, then environmental pollution is reduced, but oxygen supply for decomposition is limited
Solution Approach 1:
The patent introduces an intermediary gas exchange system that allows controlled oxygen intake and waste gas expulsion. The waterproof yet breathable membrane and controlled venting system act as intermediaries, maintaining the sealed environment to prevent pollution while providing necessary oxygen for decomposition through regulated gas exchange.
5Ease of operation
If bones are processed outside the coffin after decomposition, then cleaning and sterilization can be performed, but risk of contamination and mix-ups increases
Solution Approach 1:
The patent nests the bone processing functions within the coffin structure itself. The coffin includes integrated water supply systems for cleaning, heating elements for sterilization, and drying mechanisms, all contained within the sealed environment. This nested design maintains bone identification accuracy by keeping remains within the original coffin while providing comprehensive processing capabilities.
6Ease of manufacture
If traditional burial is used, then no special equipment is required, but environmental impact from land use is significant
Solution Approach 1:
The patent transforms the decomposition process from a land-intensive natural process to a controlled, equipment-based system. By changing parameters such as oxygen concentration, temperature, and humidity within the coffin, the system achieves efficient decomposition in a compact container, significantly reducing environmental impact from land use while maintaining implementation feasibility.
