Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning device with a bar holder and positioning bars is used to position and hold fuel cells during stacking, then positioning accuracy and holding stability are improved, but the device complexity increases due to the need for detachable components and engagement mechanisms
Solution Approach 1:
The bar holder is divided into multiple separable bar holder components that can be independently positioned and assembled. Each bar holder component can be detached and repositioned along the stacking direction, allowing precise positioning of fuel cells while simplifying the overall device structure and enabling easy adjustment without complex mechanisms
Solution Approach 2:
The positioning bars are made detachable from the bar holder components, allowing them to be removed when positioning is complete. This extraction of the positioning function enables accurate fuel cell positioning during stacking while reducing device complexity by eliminating permanent complex positioning structures
2Ease of operation
If the bar holder is configured to be dividable into pieces spaced apart, then the ease of operation for removal after stacking is improved, but the device complexity increases due to multiple components
Solution Approach 1:
The bar holder is segmented into multiple bar holder components that can be independently removed after stacking. This segmentation allows easy operation for removal by simply detaching individual components rather than removing an entire complex assembly, while the segmented structure itself is simple enough to not significantly increase device complexity
Solution Approach 2:
The bar holder components are designed with dynamic positioning capability along the stacking direction, allowing them to be moved to different positions during stacking and then easily removed after use. This dynamic design improves ease of operation while maintaining relatively simple device structure through standardized movable components
3Stability of the object's composition
If positioning bars with engagers are used to engage with fuel cell protrusions, then the holding stability is improved, but the device complexity increases due to engagement mechanisms
Solution Approach 1:
The positioning bars are designed as detachable components that can be removed after engagement with fuel cells. This extraction approach provides stable holding during the stacking process through the engager-protrusion interaction, while reducing overall device complexity by eliminating permanent complex engagement mechanisms and allowing simple removal after use
