Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If different types of cell cartridges are used to increase coupling force, then coupling force between cartridges is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The coupling protrusions are asymmetrically positioned at diagonal corners of the cell cartridges rather than being symmetrically distributed. This asymmetric arrangement allows identical cartridges to couple together in a specific orientation, achieving strong coupling force while maintaining cartridge uniformity and simplifying the manufacturing process.
2Force
If multiple types of cell cartridges are used, then coupling force is improved, but manufacturing cost increases
Solution Approach 1:
A single type of cell cartridge design serves multiple functions: it provides structural support, enables coupling with identical cartridges through diagonal corner protrusions, and allows for simplified mass production. The universal design eliminates the need to manufacture multiple cartridge types while achieving the required coupling force through the asymmetric protrusion arrangement.
3Device complexity
If cell cartridges are merely arranged without coupling members, then device complexity is reduced, but coupling force between cartridges decreases
Solution Approach 1:
The coupling mechanism is segmented into discrete coupling protrusions located at the diagonal corners of the cell cartridges. These segmented protrusions provide focused coupling points that achieve strong coupling force without requiring complex overall cartridge structures, maintaining simplicity while enhancing coupling capability.
4Ease of manufacture
If identical cell cartridges are used, then manufacturing cost is reduced, but coupling force between cartridges decreases
Solution Approach 1:
The coupling protrusions are positioned at diagonal corners in a two-dimensional plane on the cartridge surface. This spatial arrangement in another dimension allows identical cartridges to interlock effectively when stacked, achieving strong coupling force while maintaining cartridge uniformity and simplifying manufacturing through standardized production of a single cartridge type.
