Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the revolution mechanism operates at high speed, then productivity is improved, but stability deteriorates due to vibrations
Solution Approach 1:
The control device dynamically switches between first control (high speed) and second control (low speed) based on imaging conditions and operating information. This dynamic adjustment allows the system to operate at high speeds when conditions permit while switching to low speeds when stability is compromised, resolving the contradiction between productivity and stability.
Solution Approach 2:
The system changes the operational parameters of the revolution mechanism by switching between different control modes with different input factors. The first control uses parameters optimized for speed while the second control uses parameters optimized for stability, allowing the system to adapt to different operational requirements and resolve the speed-stability trade-off.
2Productivity
If the revolution mechanism operates at high speed, then productivity is improved, but image quality deteriorates due to vibrations
Solution Approach 1:
The control device dynamically adjusts the revolution speed based on real-time imaging conditions and operating information. When image quality is compromised by vibrations at high speeds, the system automatically switches to the second control mode with lower speeds, thereby maintaining image quality while still allowing high-speed operation when conditions are favorable.
Solution Approach 2:
The system changes operational parameters by switching between first control (high speed) and second control (low speed) modes. This parameter change allows the system to optimize for image quality when necessary while maintaining productivity when conditions permit, resolving the contradiction between productivity and image quality.
3Adaptability or versatility
If the control mode is switched based on imaging conditions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control device achieves multi-functionality by integrating both first control and second control capabilities within a single system. The processor is configured to switch between different control modes based on imaging conditions and operating information, allowing one device to perform multiple control functions (high-speed control and low-speed control) without requiring separate dedicated systems, thereby improving adaptability while limiting complexity increase.
Solution Approach 2:
The control device automatically switches between control modes based on imaging conditions and operating information without requiring external intervention. This self-service capability allows the system to adapt to different conditions autonomously, improving adaptability while keeping the control logic integrated within the existing device rather than adding external complexity.

AI summary
A control device controls a revolution mechanism causing an imaging apparatus to revolve. The control device includes a processor. The processor is configured to switch between first control and second control that are related to an operation of the revolution mechanism based on at least any one of an imaging condition of the imaging apparatus or operating information of the revolution mechanism, the first control is continuous control in which an input factor is a command value of a speed, and the second control is discrete control in which the input factor is a command value of a position.
