Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more functions are integrated into the defibrillation device, then the versatility and functionality are improved, but the reliability and safety are worsened
Solution Approach 1:
The patent divides the processing system into two independent processors: a first processor dedicated to core defibrillation and monitoring functions, and a second processor handling extended complex functions. This segmentation isolates the critical defibrillation functions from potential failures in extended functions, maintaining reliability while adding versatility.
Solution Approach 2:
The patent introduces an isolation circuit as an intermediary between the first processor and second processor. This intermediary component prevents direct interference between the two processors, ensuring that failures in the second processor cannot compromise the first processor's critical defibrillation functions.
2Adaptability or versatility
If more functions are integrated into the defibrillation device, then the versatility is improved, but the device complexity is worsened
Solution Approach 1:
The system is segmented into two independent processing units with distinct responsibilities. The first processor handles essential defibrillation and monitoring, while the second processor manages optional extended functions. This segmentation allows the core system to remain relatively simple while enabling functional expansion through the second processor.
Solution Approach 2:
The second processor is designed to handle various extended complex functions, making it a universal component that can support multiple different functionalities. This allows the device to maintain a relatively simple core architecture while achieving versatility through the multi-functional second processor.
3Device complexity
If a single processor handles all functions, then the device complexity is reduced, but the reliability is worsened due to potential failures affecting core functions
Solution Approach 1:
The patent segments the processing functions into two separate processors, with the first processor exclusively handling core defibrillation and monitoring functions. This ensures that even if the second processor fails, the critical first processor remains operational and unaffected.
Solution Approach 2:
The patent extracts the extended complex functions from the core processing system and places them in a separate second processor. This extraction isolates potential failure sources from the critical defibrillation functions, improving overall system reliability and safety.
4Adaptability or versatility
If extended functions are added without isolation, then the versatility is improved, but the harmful factors from extension device failures are worsened
Solution Approach 1:
The patent introduces an isolation circuit as an intermediary protective barrier between the first processor and second processor. This intermediary prevents harmful effects from second processor failures from reaching and affecting the critical first processor, thereby protecting core defibrillation functions from potential damage.
Solution Approach 2:
The isolation circuit provides beforehand protection by pre-establishing a protective barrier that cushions the first processor against potential failures in the second processor. This prior cushioning ensures that even if extended functions fail, the core functions remain safe and operational.
