Solution Overview
Problem
The existing solid oxygen generators face challenges with moisture content affecting decomposition stability, impurity gas formation, and incomplete preheating of the oxygen-producing column, leading to fluctuations in oxygen flow and reduced catalytic efficiency, especially in low-temperature environments.
Innovation Solution
The oxygen generator incorporates an oxygen-producing column with a center bore, utilizing a thermally insulating material and an impact-activated ignition mechanism, which allows for better drying, improved heat transfer, and enhanced preheating of the unreacted agent, thereby increasing oxygen production stability and purity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the oxygen-producing column is made solid with high density through pressing, then the oxygen storage capacity is increased and size is reduced, but moisture cannot be completely removed which adversely affects decomposition stability and oxygen flow rate
Solution Approach 1:
The patent introduces a porous structure within the oxygen-producing column by creating a central cavity and radial channels. This porous configuration allows moisture to be removed while maintaining the dense outer structure for high oxygen storage capacity. The pores enable airflow through the column, facilitating complete drying and stable decomposition by allowing heat and gas to penetrate the interior.
Solution Approach 2:
The patent transitions from a solid homogeneous structure to a multi-dimensional structure with a central cavity and radial channels. This dimensional change creates internal pathways for moisture removal and heat distribution, resolving the contradiction between high density and complete drying by adding internal flow dimensions rather than reducing external density.
2Temperature
If the oxygen-producing column is solid, then the high-temperature airflow can only preheat the column by means of the outside, but cannot fully preheat the internal agent, affecting oxygen production stability especially in low-temperature environments
Solution Approach 1:
The porous structure with radial channels allows high-temperature airflow to penetrate through the oxygen-producing column from the outside to the internal agent. This enables complete preheating of the entire column including the core, ensuring stable oxygen production in low-temperature environments by eliminating thermal gradients and cold spots within the column.
Solution Approach 2:
The patent uses gas flow dynamics to achieve internal preheating. The radial channels guide the high-temperature airflow through the column, utilizing pneumatic principles to distribute heat uniformly throughout the oxygen-producing agent, ensuring complete thermal activation even in cold environments.
3Ease of manufacture
If moisture is present in the oxygen-producing column, then the column can be easier to manufacture, but moisture causes side reactions that increase impurity gas content and reduces catalytic efficiency
Solution Approach 1:
The porous structure with radial channels provides efficient moisture removal pathways during and after manufacturing. This allows the column to be manufactured with ease while simultaneously enabling complete drying through the internal channels, preventing moisture-related side reactions and impurity gas formation without complicating the manufacturing process.
