Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standardized lab-on-chip cartridge design is used, then manufacturing complexity is reduced, but adaptability to different applications is limited
Solution Approach 1:
The cartridge is divided into two separate analysis devices that are connected via a connection point. Each analysis device can be independently separated and used for different applications, allowing the system to adapt to various diagnostic needs while maintaining a standardized manufacturing process for the dual cartridge unit.
2Quantity of substance
If material requirements are reduced, then manufacturing costs decrease, but structural integrity may be compromised
Solution Approach 1:
By segmenting the cartridge into two separate analysis devices connected at a defined separation point, the overall material requirement is reduced compared to producing two separate cartridges. The connection point is designed with sufficient structural integrity to maintain strength during handling and processing, while enabling clean separation when needed.
3Quantity of substance
If a dual cartridge design is implemented, then material efficiency increases, but device complexity increases
Solution Approach 1:
Two analysis devices are merged into a single dual cartridge unit that can be manufactured as one integrated structure. This merging approach improves material efficiency by reducing redundant materials while the internal connection point design maintains manageable complexity by providing a clear separation interface.
4Ease of operation
If defined separation is enabled, then ease of operation improves, but manufacturing precision requirements increase
Solution Approach 1:
The connection point is pre-designed and pre-formed during manufacturing with built-in separation features such as predetermined breaking points or form-fit connection elements. This preliminary action ensures that separation can be easily performed by the user while the manufacturing precision is established during the initial production process, balancing both requirements.
