Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing methods are used to evaluate structural properties, then measurement capability is achieved, but the measurement is invasive or destructive
Solution Approach 1:
The patent replaces traditional mechanical impact testing with acoustic wave transmission. Instead of applying mechanical force that deforms or damages the object, acoustic waves are transmitted through the object and the structural properties are determined by analyzing the transmitted wave characteristics, thereby achieving non-invasive measurement
Solution Approach 2:
The patent introduces acoustic waves as an intermediary medium to probe the structural properties of the object. The acoustic waves interact with the internal structure without causing damage, allowing measurement of damping capacity and other structural characteristics through wave transmission analysis
2Measurement precision
If fixed energy application is used, then measurement consistency is achieved, but adaptability to different object characteristics is reduced
Solution Approach 1:
The patent implements dynamic energy application where the acoustic energy parameters (amplitude, frequency, duration) are adjusted based on the specific characteristics of each object being measured. The system adapts the energy input to match the object's properties, ensuring optimal signal-to-noise ratio and measurement accuracy for diverse objects
Solution Approach 2:
The patent changes the parameters of energy application (acoustic wave amplitude, frequency, pulse duration) according to the physical characteristics of the object. By modifying these parameters dynamically, the system maintains measurement consistency across different object types while adapting to their specific properties
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables objective and quantitative measurement of structural characteristics with minimal disturbance to the object or surrounding environment, improving measurement accuracy and patient comfort in applications like dentistry.
Implementation Method 1
When an object is subjected to an impact force, a stress wave is transmitted through the object
Implementation Method 2
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 3
This stress wave causes deformations in the internal structure of the object

AI summary
The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system includes features for adjusting the energy applied to an energy application tool to compensate for the physical characteristics or type of the object, and/or for orientation of the device relative to the horizontal during measurement. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.
