Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large medical simulation unit is used to provide comprehensive simulation capabilities, then the simulation functionality and training value are improved, but the device becomes difficult to transport and prone to damage during shipping
Solution Approach 1:
The medical simulation system is divided into multiple modular components including a detection system with light source and detector, a simulation unit with haptic feedback mechanism, and a control system. These modules can be separately packaged and reassembled, enabling easy transport while maintaining full simulation functionality when combined.
Solution Approach 2:
The simulation unit is designed to accommodate multiple types of medical instruments through universal interfaces and adjustable haptic parameters. The detection system can identify different instrument types and the braking mechanism can simulate various tissue resistances, making the system versatile without requiring multiple specialized devices.
2Adaptability or versatility
If a large medical simulation unit is used to provide comprehensive simulation capabilities, then the simulation functionality is improved, but the device complexity and risk of damage during shipping increase
Solution Approach 1:
The system is segmented into independent functional modules that can be manufactured separately using standardized components and assembly procedures. This reduces the complexity of manufacturing and shipping each component while maintaining the overall functionality of the complete system.
Solution Approach 2:
A control system serves as an intermediary between the detection system and the haptic feedback mechanism. This intermediary processes detection signals and generates appropriate braking forces, simplifying the overall system architecture by centralizing the control logic and reducing direct mechanical complexity.
3Device complexity
If the light detector diode and light emitting diode are rigidly coupled, then the assembly is simpler and more stable, but the ability to optimize light transmission through the chamber is reduced
Solution Approach 1:
The light detector diode is coupled to the chamber via an adjustable mounting mechanism that allows dynamic positioning. This enables optimization of the detection angle and distance to maximize light reception while maintaining a relatively simple overall assembly structure.
Solution Approach 2:
The mounting position of the light detector diode can be adjusted to change parameters such as detection angle, distance from the chamber, and alignment with the light source. These parameter adjustments optimize the light transmission detection without requiring complex rigid coupling mechanisms.
