Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor conveyance system is used, then the device complexity is reduced, but the adaptability is worsened because it cannot simulate arterial or venous bleeding with different flow characteristics
Solution Approach 1:
The patent divides the single motor conveyance system into multiple independent motor units, each capable of controlling fluid flow to different body parts. This segmentation allows each motor to simulate different bleeding types (arterial, venous, capillary) independently, thereby improving adaptability while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent designs a multi-functional motor conveyance system where multiple motors can operate simultaneously or independently to simulate various bleeding scenarios. The system can switch between different bleeding types and locations, making it universally applicable for training different hemostasis techniques without requiring separate simulation systems.
2Ease of operation
If fixed motor speed is used, then the ease of operation is improved, but the adaptability is worsened because it cannot simulate intermittent bleeding caused by heartbeat frequency
Solution Approach 1:
The patent implements dynamic motor speed control that can adjust rotation speeds in real-time based on simulated heartbeat frequencies. The system can vary motor speeds to create intermittent bleeding patterns that mimic arterial pulsing during cardiac cycles, transforming the static motor control into a dynamic system that adapts to different physiological states.
Solution Approach 2:
The patent incorporates periodic motor operation patterns that simulate the rhythmic nature of heartbeat-induced bleeding. Motors are programmed to operate in periodic cycles, creating intermittent fluid discharge that replicates the pulsating flow characteristic of arterial bleeding during different phases of the cardiac cycle.
3Device complexity
If manual water refilling is required, then the device complexity is reduced, but the productivity is worsened due to interruptions in practice when water is depleted
Solution Approach 1:
The patent implements an automatic fluid circulation system that continuously recirculates water from the collection reservoir back to the simulation source. This closed-loop system eliminates the need for manual refilling during training sessions, ensuring continuous operation and maintaining training productivity without interruption while the system automatically manages fluid levels.
Solution Approach 2:
The system incorporates self-service features including automatic water level detection, pump activation when water is depleted, and self-circulation capabilities. The system monitors its own fluid levels and automatically initiates refilling or recirculation processes without requiring operator intervention, thereby maintaining training continuity.
4Device complexity
If pressure and flow sensing elements are not included, then the device complexity is reduced, but the measurement precision is worsened making it difficult to determine adequate pressure for successful hemostasis
Solution Approach 1:
The patent integrates pressure sensors and flow sensors that provide real-time feedback to both the control system and the trainee. The sensors measure applied pressure and fluid flow rate, displaying this information on a screen or through haptic feedback, allowing trainees to precisely determine when adequate pressure has been applied to achieve hemostasis, thereby improving measurement precision.
5Device complexity
If pulse simulation devices are not included, then the device complexity is reduced, but the measurement precision is worsened as trainees cannot confirm whether the pulse in the hemostasis state is correctly stopped
Solution Approach 1:
The patent incorporates visual indicators such as LED lights or color-coded displays that change state to indicate pulse presence or cessation. When the simulated pulse is detected or stopped, the system provides visual feedback through color changes, allowing trainees to precisely verify whether hemostasis has been successfully achieved without requiring complex diagnostic equipment.
