Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cells are manually mounted on racks by workers, then flexibility in handling different cell types is maintained, but production volume is limited and contamination risk increases
Solution Approach 1:
The mounting system is divided into separate functional modules: a picking unit with grippers for cell pickup, a transfer mechanism for movement, and a rack for storage. This segmentation allows automated high-volume handling while maintaining flexibility through programmable control of each module.
Solution Approach 2:
A transfer mechanism acts as an intermediary between the picking unit and the rack, enabling automated cell transport. This intermediary component facilitates high-speed automated mounting while isolating the complexity of automation from the storage system.
2Strength
If conventional mounting jigs with clamps are used, then cells can be securely fixed, but the cell case may be deformed or damaged
Solution Approach 1:
The fixing mechanism uses localized contact points instead of distributed clamping force. The fixing protrusions make contact only at specific locations on the cell case, providing sufficient fixation strength while avoiding deformation of the cell case structure.
Solution Approach 2:
The fixing protrusions are simple, replaceable components that can be easily manufactured and replaced if needed. This approach uses simple geometric features rather than complex clamping mechanisms, reducing the risk of cell damage.
3Quantity of substance
If cells are densely arranged on racks, then storage capacity increases, but cell alignment precision decreases leading to module assembly issues
Solution Approach 1:
The rack features asymmetric guiding structures including guide grooves and positioning protrusions that provide precise alignment references for cells. These asymmetric features ensure correct cell orientation and position even when cells are densely arranged, maintaining alignment precision while maximizing storage capacity.
Solution Approach 2:
Cells are pre-aligned using guide grooves and positioning features during the mounting process before final placement on the rack. This preliminary alignment action ensures precise cell positioning is achieved before dense arrangement, preventing assembly issues in subsequent module construction.
