Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seals are used to prevent leakage, then sealing effectiveness is improved, but coffee residue accumulates on seals causing increased leakage over time
Solution Approach 1:
The brewing chamber is designed to be removable from the brewing assembly, allowing complete removal and cleaning of the chamber and seals. This extracts the sealing components from the permanent structure, enabling thorough cleaning to remove accumulated coffee residue that would otherwise degrade sealing effectiveness over time.
Solution Approach 2:
The brewing chamber and seals are designed as disposable or easily replaceable components. After extensive use and residue accumulation, the seals can be discarded and replaced with new ones, recovering the sealing function without the need for complex cleaning mechanisms or residue removal systems.
2Stress or pressure
If constricted outlets are used to create back pressure, then brewing pressure is improved, but excessive foam and turbulence are generated
Solution Approach 1:
The outlet geometry is optimized by changing parameters such as outlet diameter, shape, and position to achieve the desired back pressure without creating excessive turbulence. The outlet is designed with specific dimensional parameters that balance pressure generation with smooth coffee flow, reducing foam formation while maintaining brewing pressure.
3Productivity
If hot water travels through multiple parts, then brewing process is completed, but heat loss occurs reducing coffee temperature
Solution Approach 1:
The brewing chamber and outlet components are pre-heated before coffee brewing to reduce heat loss. The system performs preliminary heating of all water-contact surfaces, so when hot water travels through the brewing assembly, minimal heat is transferred to the components, maintaining coffee temperature throughout the brewing process.
4Speed
If centrifugal force is used to expel coffee, then brewing speed is improved, but coffee particles remain in grinder affecting next batch
Solution Approach 1:
The grinder and brewing system are designed to continuously process coffee beans through the brewing cycle. The grinder operates continuously with the brewing assembly, ensuring that ground coffee particles are immediately processed and expelled with each brewing cycle, preventing particle accumulation that would affect the particle size distribution of subsequent batches.
