Solution Overview
Problem
Conventional X-ray fluoroscopic imaging apparatuses have a complex operation interface due to multiple motion axes, leading to increased switch numbers, larger operation elements, and a higher risk of unintentional shifts during examinations and treatments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each direction switch is installed relative to each plurality of motion-axes, then the shifting control for each motion-axis can be independent and precise, but the number of switches increases and the operation element becomes larger
Solution Approach 1:
The direction switches are designed to be universal and multi-functional, allowing the same set of direction switches to control multiple motion-axes through a selection mechanism. Instead of having dedicated switches for each axis, the system uses a combination of axis selection and direction selection to achieve precise control with fewer physical switches.
Solution Approach 2:
The control function is segmented into two independent parts: motion-axis selection and direction selection. This segmentation allows the system to separate the choice of which axis to move from the choice of movement direction, enabling a smaller number of switches to control multiple axes through combinatorial selection.
2Measurement precision
If each direction switch is installed relative to each plurality of motion-axes, then the shifting control for each motion-axis can be independent and precise, but the operation element becomes larger and disturbs examination and treatment
Solution Approach 1:
The direction switches serve multiple functions by controlling different motion-axes based on the selected axis. This multi-functionality reduces the physical footprint of the operation element while maintaining precise control capabilities across multiple degrees of freedom.
Solution Approach 2:
The control interface merges the axis selection and direction control into a unified operation element. By combining these functions in a compact arrangement, the system reduces the overall size and disturbance to examination and treatment procedures.
3Adaptability or versatility
If multiple direction switches are provided for multiple motion-axes, then the shifting control can be comprehensive, but it becomes difficult to comprehend the desired switch and prompt operation is delayed
Solution Approach 1:
The control interface is segmented into distinct selection stages: first selecting the motion-axis, then selecting the direction. This segmentation presents fewer options at each step, making it easier for the operator to comprehend and select the desired switch without being overwhelmed by the total number of possible movements.
Solution Approach 2:
The system requires preliminary selection of the motion-axis before enabling direction control. This preliminary action narrows down the available options and makes the subsequent direction selection more intuitive and faster, improving overall operational speed and ease.
4Ease of operation
If direction switches are readily accessible for quick operation, then prompt operation can be achieved, but the risk of erroneous operation and unintentional shifting increases
Solution Approach 1:
The operation is segmented into multiple sequential steps (axis selection followed by direction selection), which slows down the overall process slightly but significantly reduces erroneous operations. The segmentation ensures that the operator consciously selects both the axis and direction, reducing accidental activations.
Solution Approach 2:
The preliminary selection of motion-axis acts as a confirmation step before direction control is activated. This preliminary action serves as a safety mechanism that prevents unintentional shifting while still allowing prompt operation within each selection stage.
