Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid state reaction containers with gas-permeable bottoms face limitations in removing gaseous reaction products efficiently, leading to slower reaction times and reduced throughput due to reliance on diffusion processes against gravity, which can hinder the progress of metal powder production.
Innovation Solution
A reaction container with a detachable mesh fabric and support construction allows for convective transport of gases by gravity, enabling efficient removal of by-products and accommodating different powder sizes, with the option to use multiple containers for increased scalability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional boats with gas-permeable bottoms are used, then the structure is simple, but the removal of gaseous reaction products is inefficient due to reliance on diffusion processes against gravity
Solution Approach 1:
The patent inverts the conventional approach by allowing the powder bed to drain downwards through the gas-permeable bottom under gravity, while the gas flow moves upwards through the powder bed. This reversal of the conventional configuration enables gaseous reaction products to be removed efficiently by gravity-driven convective flow rather than diffusion against gravity, significantly improving reaction productivity.
Solution Approach 2:
The patent introduces a movable piston that can be displaced to vary the volume of the reaction container dynamically. This allows the system to adapt to different reaction conditions and powder bed volumes, optimizing the gas flow patterns and reaction efficiency. The dynamic adjustment capability enables the system to maintain optimal productivity across varying operational requirements.
2Quantity of substance
If the reaction container size is increased for industrial-scale reactions, then the quantity of reactants can be increased, but the efficiency of gas removal may decrease
Solution Approach 1:
The patent segments the reaction container into multiple zones with a gas-permeable bottom that allows partitioning of the powder bed. This segmentation enables independent gas flow paths and drainage zones, ensuring that even in large-scale reactions, gaseous products can be efficiently removed from all regions. The segmented structure maintains high reaction efficiency while accommodating industrial quantities of reactants.
Solution Approach 2:
The patent introduces a vertical dimension for gas flow and drainage by implementing a gas-permeable bottom that allows downward movement of powder and upward flow of gas. This three-dimensional configuration enables efficient gas removal throughout the entire powder bed volume, maintaining reaction efficiency regardless of the horizontal size or quantity of reactants processed.
3Adaptability or versatility
If mesh fabric is made detachable for easy replacement, then adaptability to different powder sizes is improved, but the structural stability may be reduced
Solution Approach 1:
The patent segments the container structure into detachable components, specifically the mesh fabric and support plate, which can be independently removed and replaced. This segmentation enables easy adaptation to different powder sizes by selecting appropriate mesh configurations while maintaining overall structural stability through the robust frame and support construction. The modular design allows frequent replacement without compromising the integrity of the entire system.
Solution Approach 2:
The patent applies different local qualities to various components: the mesh fabric provides flexibility and adaptability for different powders, while the support plate and frame provide rigid structural stability. This differentiation of local qualities allows the detachable mesh to be easily replaced for adaptability while the permanent support structure maintains reliable structural integrity throughout operation.

Implementation Method 1
the removal of the gaseous components formed during the reaction is effected not only by diffusion processes, but also by convective material transport processes caused by gravity
Implementation Method 2
The transport of the gas through the powdery solid can be effected either by diffusion, i.e., based on a concentration gradient
