Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dihydrogen generators are not reusable and the catalysts cannot be recovered, leading to high disposal costs and limited industrial development.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the generator uses a fixed catalytic system integrated into the enclosure, then the structure is simple and reliable, but the generator cannot be reused and catalysts cannot be recovered
Solution Approach 1:
The catalytic system is divided into a separate catalysis housing that can be detached from the enclosure. This segmentation allows the catalytic system to be removed and reused with different enclosures, while each component maintains its structural integrity and reliability when properly assembled.
Solution Approach 2:
The catalytic system is designed as a universal component that can be attached to multiple enclosures and reused across different generator units. The standardized connection interface enables the same catalytic system to serve multiple functions and multiple generators, enhancing adaptability without compromising reliability.
2Adaptability or versatility
If the catalytic system is made removable and reusable, then reusability and catalyst recovery are enabled, but the device complexity increases
Solution Approach 1:
By segmenting the generator into modular components (enclosure and catalytic system), the design enables reusability while keeping each module relatively simple. The catalysis housing with integrated catalyst and filter assembly forms a self-contained unit that is simple in itself but provides complex functionality when combined with the enclosure.
Solution Approach 2:
The catalysis housing contains nested components including the catalyst support, filter assembly, and connection elements within a compact structure. This nesting approach allows the complex catalytic system to be contained in a relatively simple housing that can be easily attached and detached from the enclosure.
3Ease of manufacture
If the generator is designed for single-use, then manufacturing and disposal are simple, but disposal costs are high and environmental impact increases
Solution Approach 1:
The design enables recovery of the catalytic system by allowing it to be detached from the spent enclosure. The catalyst contained in the catalysis housing can be recovered and reused, preventing catalyst loss and reducing the need for continuous manufacturing of new catalytic systems, thereby reducing disposal costs and environmental impact.
Solution Approach 2:
The catalytic system is designed with localized high-value components (catalyst and filter) concentrated in the catalysis housing, while the enclosure contains lower-value consumable materials. This local quality differentiation enables selective recovery of high-value components while simplifying disposal of consumable parts, reducing overall disposal costs.
