Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If accessories/components are stored in the home ventilator after use, then storage convenience is improved, but contamination by bacteria and viruses occurs during storage
Solution Approach 1:
The patent extracts the storage function from the main ventilator body by providing a separate storage chamber that is communicably connected but functionally distinct. This allows accessories to be stored in a dedicated space that can be independently disinfected and maintained, preventing cross-contamination between the storage area and the patient interface components.
Solution Approach 2:
The storage chamber acts as an intermediary space between the external environment and the main ventilator system. By providing this intermediate storage zone with separate access and disinfection capabilities, the patent creates a buffer that protects the main system from contamination while maintaining storage functionality.
2Device complexity
If a single layer of primary/medium-efficiency filter cotton is used for air source filtration, then device complexity is reduced, but dust particles smaller than 5 μm including bacteria and viruses can enter the ventilator
Solution Approach 1:
The patent segments the air filtration function into multiple independent filtering stages. Instead of relying on a single filter layer, the system divides filtration into primary filtration (larger particles) and secondary filtration (smaller particles including bacteria and viruses), with each stage handling specific particle size ranges to achieve comprehensive protection.
Solution Approach 2:
The patent adds a new dimension to the filtration system by introducing a second filtration layer that operates in series with the first. This multi-layer approach transforms the filtration process from a single-plane operation to a multi-stage sequential process, enabling the system to capture particles across different size ranges that a single filter could not address.
3Reliability
If air filter cotton is replaced every half a month to a month, then filtration effectiveness is maintained, but user convenience deteriorates due to uncertain replacement timing and frequent maintenance
Solution Approach 1:
The patent implements preliminary action by providing pre-installed spare filter layers within the device. Instead of requiring users to externally source and install replacement filters, the system comes equipped with backup filtration layers that can be quickly swapped in when the primary filters become saturated, eliminating the need for users to time and coordinate replacement schedules.
Solution Approach 2:
The patent enables self-service maintenance through a simplified filter replacement mechanism. The multi-layer filter design allows users to easily access and replace spent filters without requiring technical expertise or special tools, transforming a complex maintenance task into a simple user-friendly operation that can be performed independently.
