Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a counter-weight drive mechanism is used to enable elevation adjustment, then the apparatus can achieve imaging at lower positions, but the apparatus becomes heavy and complex
Solution Approach 1:
The patent removes the counter-weight component entirely from the elevation adjustment mechanism. Instead of using a counter-weight system, the invention employs a motor-driven threaded elongate member that directly adjusts the elevation of the X-ray tube assembly, eliminating the heavy counter-weight while maintaining elevation adjustment capability
Solution Approach 2:
The patent replaces the mechanical counter-weight drive mechanism with an electrical motor system. The motor drives a threaded elongate member that converts rotational motion into linear elevation adjustment, substituting complex mechanical balancing with a simpler electrical actuation system
2Length of moving object
If a counter-weight drive mechanism is used to enable elevation adjustment, then the apparatus can achieve imaging at lower positions, but the construction becomes complicated and control becomes difficult
Solution Approach 1:
The patent removes multiple complex components from the elevation mechanism, including the counter-weight, complex gear systems, and multiple adjustment units. The simplified design uses a single motor connected directly to a threaded elongate member, dramatically reducing the number of parts and simplifying the overall construction
Solution Approach 2:
Instead of using a complex mechanical system that requires multiple components working together to achieve elevation adjustment, the patent inverts the approach by using a simple motor-driven threaded mechanism where a single actuator provides direct control, making the system easier to construct and control
3Ease of operation
If a counter-weight drive mechanism is used, then elevation adjustment is possible, but sufficient accuracy and fast adjustment speed cannot be achieved
Solution Approach 1:
The patent replaces the mechanical counter-weight system with an electrical motor control system. The motor can be precisely controlled to achieve accurate elevation positions, and the threaded elongate member provides fine adjustment capability, enabling both high accuracy and fast adjustment speeds that were not achievable with the mechanical system
Solution Approach 2:
The patent changes the control parameter from mechanical force balancing to electrical motor control. By using electrical signals to control motor speed, direction, and position, the system achieves precise elevation adjustment with fast response time, overcoming the limitations of the mechanical system
