Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fluid-operated circuit with multiple hoses and auxiliary devices is used, then the ventilator can perform pulmonary ventilation functions, but the assembly complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent merges multiple separate components (hoses, pressure sensors, flow meters, solenoid valves, oxygen detectors) into a single integrated circuit board. This consolidation maintains all necessary pulmonary ventilation functions while dramatically reducing assembly complexity from multiple separate components to a single unified structure.
Solution Approach 2:
The circuit board serves multiple functions simultaneously: it acts as the fluid transport pathway, houses pressure sensors, flow meters, solenoid valves, and oxygen detectors. This multi-functionality eliminates the need for separate auxiliary devices for each function, reducing overall device complexity while maintaining comprehensive ventilation capability.
2Reliability
If multiple separate components are assembled to form the ventilator circuit, then functional requirements are met, but manufacturing time and cost increase
Solution Approach 1:
By combining multiple separate components into a single integrated circuit board, the manufacturing process transitions from assembling multiple individual parts to producing one unified component. This significantly reduces manufacturing time and labor costs while maintaining all necessary ventilation functions through the integrated design.
3Reliability
If a box-shaped structure with separate circuit and control unit is used, then the ventilator achieves required functionality, but the overall size becomes bulky
Solution Approach 1:
The patent integrates the circuit and control unit into a single unified structure, eliminating the need for separate housing compartments. This consolidation reduces the overall device volume while maintaining all ventilation capabilities, making the ventilator more suitable for emergency vehicles and home care settings.
4Reliability
If a complex fluid-operated circuit is assembled, then the ventilator can mix air and oxygen and deliver it under pressure, but the device becomes unsuitable for emergency vehicles and home care
Solution Approach 1:
The integrated circuit board combines all gas mixing and delivery functions (air-oxygen mixing, pressure generation, flow control) into a single compact unit. This maintains the necessary ventilation capabilities while dramatically improving portability for emergency vehicles and home care environments where space is limited.
