Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxygen generators experience destabilization due to localized melting during decomposition and oxygen loss, leading to interrupted oxygen flow, especially in vibrating environments, and produce oxygen at high temperatures.
Innovation Solution
Incorporating multifunctional zeolites with transition metals into the oxygen generating composition, which act as both binders and catalysts, replacing conventional binders and catalysts, to maintain mechanical stability and control decomposition without forming a liquid phase, thus ensuring continuous oxygen production at lower temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional binders and catalysts are used in oxygen generators, then the decomposition reaction can proceed, but the composition becomes mechanically unstable due to liquid phase formation during decomposition
Solution Approach 1:
The invention uses a composite material system consisting of chlorate/perchlorate oxygen source combined with zeolite binder-catalyst. The zeolite framework integrates both binding and catalytic functions in a single composite material that maintains structural integrity while enabling the decomposition reaction, preventing liquid phase separation that occurs with conventional separate binder and catalyst systems
Solution Approach 2:
The zeolite component performs multiple functions simultaneously: it acts as a binder to hold the composition together, as a catalyst to promote decomposition reaction, and as a structural framework that prevents liquid phase formation. This multi-functionality eliminates the need for separate binder and catalyst components, resolving the mechanical instability issue
2Productivity
If the oxygen generator operates at high decomposition temperatures, then the decomposition reaction proceeds rapidly, but the oxygen stream becomes too hot for breathable use
Solution Approach 1:
The invention changes the chemical and physical parameters of the catalyst system by using zeolite with specific framework structures and metal ion compositions. This alters the decomposition mechanism to proceed at lower temperatures while maintaining high reaction rates, producing breathable oxygen at controlled temperatures between 20-40°C
3Speed
If conventional catalysts are used to speed up decomposition, then the reaction rate increases, but the mechanical stability of the composition deteriorates due to liquid zone formation
Solution Approach 1:
The zeolite composite material provides a rigid framework structure that maintains mechanical stability while the embedded metal ions (Fe³⁺, Co²⁺, Mn³⁺, Ni²⁺, Cu²⁺) provide catalytic activity. This composite structure prevents the liquid phase formation that occurs with conventional catalysts, allowing high decomposition rates without sacrificing mechanical integrity
4Ease of operation
If the oxygen generator is used in vibrating environments, then portability is improved, but the liquid zone causes separation and interrupts oxygen flow
Solution Approach 1:
The zeolite's multi-functional role as binder-catalyst-structural-framework creates a unified solid structure that resists separation under vibration. The interconnected zeolite framework traps the decomposition reaction within a stable matrix, preventing the liquid zone from causing separation and ensuring continuous oxygen flow even in portable, vibrating applications
