Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a solid state hydrogen storage material based on metal hydride is used, then hydrogen storage capacity per unit mass is improved, but the temperature required for hydrogen release reaction increases and power consumption for heating increases
Solution Approach 1:
The heat conduction fin is segmented into multiple tube passing holes connected by linear-shaped connecting portions, forming a net structure that divides the heat conduction function into distributed segments, improving heat distribution efficiency
Solution Approach 2:
The heat conduction fin adopts a net structure with empty spaces that allow hydrogen storage materials to be positioned within, creating a porous-like configuration that enhances both heat conduction and hydrogen storage capacity simultaneously
2Weight of moving object
If a heat conduction fin with net structure is used, then weight of the hydrogen storage system is reduced, but heat conduction performance may be degraded
Solution Approach 1:
The heat conduction fin is divided into multiple tube passing holes connected by linear-shaped connecting portions, creating a segmented net structure that reduces material usage and weight while maintaining heat conduction pathways
Solution Approach 2:
The linear-shaped connecting portions extend in specific directions to connect tube passing holes, creating a three-dimensional net structure that maintains heat conduction efficiency across multiple dimensions while reducing overall material quantity
3Quantity of substance
If empty spaces are utilized in the heat conduction fin, then hydrogen storage capacity is increased, but device complexity increases
Solution Approach 1:
The heat conduction fin serves multiple functions simultaneously: it conducts heat through the net structure and provides empty spaces for hydrogen storage materials, making it a multi-functional component that reduces overall device complexity
Solution Approach 2:
The heat conduction function and hydrogen storage function are merged into a single integrated structure where the net structure of the heat conduction fin creates natural empty spaces for storing hydrogen storage materials
