Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal needles are used in ultrasonic activators, then the structure is strong and durable, but the needles break easily when colliding with the inner wall of the root canal
Solution Approach 1:
The patent changes the material parameter of the needle from metal to flexible material, fundamentally altering its mechanical properties to be compliant rather than rigid, preventing breakage while maintaining structural integrity
Solution Approach 2:
The needle is constructed as a composite structure combining flexible material with internal reinforcement elements, creating a material that is both compliant to avoid breakage and strong enough to perform the required function
2Stability of the object's composition
If rigid axial and bolt connections are used to assemble the needle, then the structure is stable, but the movement freedom is restricted and deadlock occurs when blocked
Solution Approach 1:
The patent replaces rigid axial and bolt connections with flexible connecting structures that allow multi-directional movement, enabling the needle to adapt its position and avoid deadlock while maintaining structural coherence
Solution Approach 2:
The connection structure is designed to be dynamic rather than static, allowing the needle to move freely in multiple directions and adapt to blocking conditions, transforming the system from rigid to adaptable
3Adaptability or versatility
If hybrid control of UVC lamp, LED indicators and motor is implemented, then the functionality is enhanced, but the voltage becomes volatile and unstable
Solution Approach 1:
The patent implements a feedback control mechanism through a control board that monitors voltage and adjusts power distribution to the UVC lamp, LED indicators, and motor, maintaining stable voltage despite varying operational demands
Solution Approach 2:
The patent replaces direct mechanical electrical connections with an electronic control system that manages power distribution, substituting rigid electrical wiring with intelligent voltage regulation to handle multiple functional loads
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 flexible needle system prevents breakage and deadlock, while the constant voltage supply stabilizes power, enhancing treatment efficiency and safety by enabling self-adaptation and reliable operation of the UVC lamp and LED indicators.
Implementation Method 1
The motor is connected with the eccentric wheel by an input axis at the front end
Implementation Method 2
The connecting rod is connected through the spherical joint to the ball-shaped slot of the eccentric wheel and therefore, a spherical pair is formulated to allow for some degree of freedom
Implementation Method 3
The oscillatory needle is mounted inside the soft rubber cover through a cylindrical joint, which has formulated a cylindrical pair and allows for four degrees of freedom
Implementation Method 4
The PCB main control board uses keys to operate the driver board and motor
