Mobile X-ray Generator Filament Brush Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile X-ray imaging apparatuses, cables often come into contact with objects during positioning, posing a risk of infection and complicating the imaging process due to their fixed length, which is set for maximum extension.
Innovation Solution
The apparatus employs conductor filaments and brushes along the supporting post, allowing for vertical movement and power transmission without external cables, reducing the likelihood of cable contact with the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable length is set to connect the X-ray tube and control device when the arm is in the highest position and maximally extended, then the X-ray tube can be connected to the control device in the maximum extended state, but the cable may accidentally come into contact with the object when the arm is lowered or contracted during positioning operation
Solution Approach 1:
The patent removes the external cable from the system by integrating the power supply function into the X-ray generator itself. The generator contains its own power supply unit, eliminating the need for cables connecting to an external control device. This extraction of the power supply function from the external environment resolves the cable contact issue while maintaining reliable power supply.
Solution Approach 2:
The X-ray generator is designed to be self-sufficient with an integrated power supply unit that provides power directly to the X-ray tube. The generator autonomously manages its own power requirements without external cable connections, enabling independent operation and eliminating the harmful cable-object contact during positioning operations.
2Length of moving object
If the cable is set to a fixed length for maximum extension, then the arm can reach the highest position with full extension, but the operator must perform positioning operation with meticulous attention to prevent cable contact with the object
Solution Approach 1:
By removing the external cable and power supply from the system, the patent eliminates the constraint that limited arm movement. The operator can now move the arm through its full range of motion without worrying about cable entanglement or contact with the object, significantly improving ease of operation during positioning.
Solution Approach 2:
The integrated power supply design allows the arm to move dynamically through its complete range of motion without the static cable constraint. The system adapts freely to positional changes, enabling smooth and unrestricted positioning operations while maintaining full extension capability.
3Adaptability or versatility
If multiple cables are used for power source, detection signals, and control functions, then all necessary electrical connections can be established, but the complexity of cable management increases and the risk of cable contact with the object increases
Solution Approach 1:
The patent combines multiple electrical connection functions (power supply, detection signals, control) into a single integrated X-ray generator unit. All necessary electrical connections are internal to the generator, eliminating the need for multiple external cables and their associated management complexity while maintaining full adaptability for imaging operations.
Solution Approach 2:
By extracting all electrical connection requirements from the external cable system and integrating them into the self-contained generator, the patent eliminates the complex cable management issue while preserving complete electrical functionality for power, detection, and control operations.

Function Achieved in This Case
This configuration enhances operability by eliminating cable contact risks and simplifying positioning operations, improving safety and efficiency in X-ray imaging.
Implementation Method 1
A plurality of conductor filaments are arranged at intervals along an axial direction on the supporting post. A plurality of conductor brushes coming into contact with the filaments respectively are arranged on the other end of the arm. The brushes move vertically along the filaments in a state of coming into contact with the filaments with the vertical movement of the arm. The main body supplies electric power to the X-ray generator through the filaments and the brushes.
