Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed amount of energy is applied to all objects, then the measurement process is simple, but the measurement accuracy and object safety deteriorate due to lack of adaptation to physical characteristics
Solution Approach 1:
The device dynamically adjusts the amount of energy applied based on real-time detection of object physical characteristics. The control mechanism modifies energy parameters (such as impact force, vibration amplitude, or thermal energy) during the measurement process to match the detected properties of the object, thereby achieving accurate measurements without causing damage while adapting to each unique object.
Solution Approach 2:
The system incorporates a feedback loop where sensors detect physical characteristics of the object (such as density, elasticity, or structural properties), and this information is fed back to the control mechanism which then adjusts the energy application accordingly. This closed-loop control ensures measurement accuracy while preventing excessive energy application that could damage the object.
2Reliability
If high energy is applied to ensure measurement reliability, then measurement reliability improves, but object damage and patient discomfort worsen
Solution Approach 1:
The device changes energy application parameters (such as force magnitude, duration, frequency, or intensity) based on detected object characteristics. For example, if the object is detected to be fragile or the patient shows sensitivity, the system automatically reduces energy parameters to prevent damage while maintaining sufficient measurement reliability through adaptive adjustment.
Solution Approach 2:
The system applies just enough energy to achieve reliable measurement without excessive energy application. By detecting object properties first, the device determines the minimum necessary energy level required for accurate measurement, applying only that amount rather than using a fixed high energy level that would guarantee reliability but cause damage.
3Adaptability or versatility
If the device operates at varying angles from horizontal, then operational flexibility improves, but measurement accuracy deteriorates due to gravity's effect on energy application
Solution Approach 1:
The device incorporates angle detection (through accelerometers or inclinometers) that feeds back to the control mechanism. When the device is detected to be at an angle from horizontal, the control mechanism compensates by adjusting energy application parameters to account for gravity's influence, thereby maintaining measurement accuracy regardless of device orientation.
Solution Approach 2:
The system dynamically adjusts energy application based on real-time detection of device orientation. As the device angle changes during operation, the control mechanism continuously modifies energy parameters to compensate for gravitational effects, ensuring consistent measurement accuracy across varying operational positions and orientations.

Function Achieved in This Case
Enables objective and quantitative measurement of structural characteristics with minimal disturbance, improving patient comfort and measurement accuracy by adjusting energy application according to the object's specific conditions and environment.
Implementation Method 1
When an object is subjected to an impact force, a stress wave is transmitted through the object
Implementation Method 2
This stress wave causes deformations in the internal structure of the object
Implementation Method 3
The ability of the object to dissipate mechanical energy, commonly referred to as the 'damping capacity' of the object
Implementation Method 4
As the object deforms it acts, in part, as a shock absorber, dissipating a portion of the mechanical energy associated with the impact
Implementation Method 5
an inclinometer adapted to measure inclination of the energy application tool relative to the horizontal
