Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radiolucent patient support is physically attached to the mobile imaging device for intraoperative imaging, then imaging stability and precision are improved, but the mobility and flexibility of the imaging device are reduced
Solution Approach 1:
The table system is divided into separate functional modules: a radiolucent patient support frame that can be detached from the table base, and a mobile imaging device that does not require physical attachment to the table. This segmentation allows the imaging device to move independently while the radiolucent frame provides the necessary imaging clearance.
Solution Approach 2:
The requirement for physical attachment between the table system and mobile imaging device is extracted and eliminated. The patent enables imaging without mechanical connection by designing the table to retract or lower the radiolucent frame, creating sufficient clearance for the imaging device to operate independently.
2Reliability
If the mobile imaging device remains attached to the surgical table during surgery, then imaging stability is improved, but the ability to relocate the device between patients or rooms is reduced
Solution Approach 1:
The table system incorporates dynamic movement capabilities through actuators that can extend or retract the radiolucent frame, and move the table top vertically. This dynamic adjustment allows the system to adapt between imaging and non-imaging states, enabling quick transitions without permanent attachment.
Solution Approach 2:
The table system provides self-adjustment capabilities through automated actuators that position the radiolucent frame and table top to create imaging clearance without requiring external attachment to the mobile imaging device. The system serves its own imaging needs through internal mechanical adjustments.
3Length of stationary object
If the frame projects at least 1 meter past the platform for imaging clearance, then unobstructed imaging is improved, but the balance and stability of the table system are reduced
Solution Approach 1:
Counterweights are integrated into the table system to balance the extended radiolucent frame. These counterweights offset the moment created by the frame projecting 1 meter or more past the platform, maintaining table stability and preventing tipping while preserving the necessary imaging clearance.
Solution Approach 2:
The system dynamically changes the position of the radiolucent frame through actuator-driven extension and retraction. By adjusting the frame's position parameter, the system can achieve the required 1 meter imaging clearance when needed while returning to a retracted, more stable configuration when imaging is not required.
