Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple methods like weight falling or mechanical compression are used to create experimental nerve tissue damage, then the experiment can be performed with basic equipment, but the trauma impact parameters (force amplitude, duration, direction, surface area) cannot be precisely controlled or measured
Solution Approach 1:
The patent replaces simple mechanical impact methods with a controlled robotic arm system equipped with sensors. The robotic arm can precisely control force amplitude, duration, direction, and surface area of impact, while load cells and accelerometers measure these parameters accurately, resolving the contradiction between simple setup and precise measurement.
Solution Approach 2:
The patent incorporates sensors (load cells, accelerometers) that provide real-time feedback on impact parameters to a control system. This feedback mechanism enables precise control and measurement of trauma parameters, allowing the system to adjust and monitor force amplitude, duration, direction, and surface area accurately during experiments.
2Device complexity
If existing trauma simulation methods are used, then the experiment can be conducted with minimal equipment, but the force transferred to tissue and impact characteristics cannot be exactly determined
Solution Approach 1:
The patent replaces unreliable simple mechanical methods with a sophisticated robotic arm system that integrates sensors and control systems. This substitution enables accurate determination of force transferred to tissue and impact characteristics while maintaining experimental reliability through precise control and measurement capabilities.
Solution Approach 2:
The patent introduces sensors (load cells, accelerometers) as intermediary measurement devices between the impact source and the tissue sample. These intermediaries accurately capture impact parameters and force transfer characteristics, enabling reliable determination of trauma parameters without directly contacting the tissue.
3Productivity
If standard trauma testing procedures are used, then the test can be performed routinely, but the parameters of trauma impact (force amplitude, duration, angle, surface) cannot be standardized or reproduced
Solution Approach 1:
The patent employs a dynamic robotic arm system with programmable control that can adapt to different trauma scenarios. The system can standardize impact parameters (force amplitude, duration, angle, surface area) through precise control while maintaining the ability to vary parameters for different experimental requirements, achieving both standardization and flexibility.
Solution Approach 2:
The patent incorporates sensors that provide real-time feedback on impact parameters, enabling the control system to standardize and reproduce trauma parameters consistently. The feedback mechanism ensures that each test can be precisely controlled and reproduced, achieving standardization while maintaining testing efficiency through automated control.
