Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If known f-ESWT devices use a trolley-mounted base unit with AC power connection, then high voltage pulse generation is achieved, but portability and ease of operation deteriorate
Solution Approach 1:
The device is divided into two main segments: a handheld transducer handpiece that contacts the patient and a portable base unit that generates high voltage pulses. This segmentation allows the handpiece to be lightweight and portable while the base unit contains the power generation components, resolving the contradiction between portability and high voltage generation capability.
Solution Approach 2:
A robust electrical cable acts as an intermediary, connecting the portable base unit to the handheld transducer handpiece. This cable transmits high voltage pulses from the base unit to the handpiece, enabling the handpiece to generate shock waves without containing its own power source, thus maintaining portability while achieving high voltage pulse generation.
2Power
If known f-ESWT devices use a trolley-mounted base unit, then shock wave generation is achieved, but device size and complexity increase
Solution Approach 1:
The system is segmented into a compact handheld transducer handpiece and a portable base unit. The handpiece contains only the transducer and necessary control electronics, while the base unit houses the power electronics and control system. This segmentation reduces the complexity of each individual component and allows for more manageable device structure compared to a single integrated trolley-mounted system.
Solution Approach 2:
The device incorporates dynamic elements including a movable transducer head that can be positioned and angled independently, and a base unit with adjustable power output settings. This dynamic design allows the device to adapt to different treatment requirements without requiring a complex fixed structure, simplifying the overall device architecture.
3Duration of action of stationary object
If known f-ESWT devices require AC wall outlet connection, then continuous power supply is achieved, but portability and accessibility deteriorate
Solution Approach 1:
The power supply system is segmented into a portable battery-powered base unit and the handheld transducer. The base unit contains a rechargeable battery that provides continuous power supply without requiring AC wall outlet connection. This segmentation enables the device to be used in mobile settings while maintaining continuous operation capability.
Solution Approach 2:
The base unit incorporates a rechargeable battery that can be recharged from AC power when available, but operates autonomously on battery power when mobile. This self-service power system allows the device to function independently without continuous connection to external power sources, greatly improving accessibility and portability.
