MRI Bed Cable Routing via Internal Conduit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic resonance imaging (MRI) apparatuses face inefficiencies and safety concerns due to cables obstructing operations when the top panel is outside the imaging space, particularly when multiple receiving coils are used, reducing operation efficiency and safety.
Innovation Solution
A magnetic resonance imaging apparatus with a bed device that includes a top panel with connection ports for signal transmission cables, which are electrically connected through the bed support section, allowing the cables to be guided internally and reducing external exposure, thus preventing obstruction during subject mounting and imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cables are arranged externally with slack to adapt to top panel movement, then the cable can accommodate panel movement, but the cable obstructs operation and reduces safety when the top panel is outside the imaging space
Solution Approach 1:
The cable is routed through the bed support section, which acts as a protective channel or conduit. The cable is nested within the structural framework of the bed support section, allowing it to move with the top panel while being concealed and organized, thus preventing obstruction during operations.
Solution Approach 2:
The bed support section serves as an intermediary structure that manages the cable routing. Instead of the cable directly connecting the receiving coil to the signal processing section in a vulnerable external path, the bed support section mediates the cable's path, guiding it through a protected route that accommodates movement while preventing obstruction.
2Area of stationary object
If multiple receiving coils are used to collect image data in a wide range, then the imaging coverage is improved, but the number of cables increases and further reduces operation efficiency and safety
Solution Approach 1:
The bed support section serves as a universal cable management system that can accommodate multiple cables from multiple receiving coils. Instead of requiring separate management solutions for each cable, the bed support section provides a unified routing path that handles all cables consistently, maintaining operation efficiency regardless of the number of coils used.
Solution Approach 2:
Multiple cables are routed through the same bed support section structure, nesting them within the protective conduit. This organized arrangement prevents cables from tangling or obstructing operations, even when multiple receiving coils are simultaneously in use, thus maintaining safety and operational efficiency.
3Ease of operation
If the cable is pulled to a position above the top panel outside the imaging space, then the cable connects the receiving coil with the signal processing section, but the cable becomes a factor of reduction in operation efficiency or safety
Solution Approach 1:
The harmful aspect of the cable (its obstruction and safety hazard) is extracted by rerouting it away from the operational area. Instead of the cable being pulled above the top panel where it obstructs operations, the cable is extracted from this harmful position and routed through the bed support section, removing the obstruction hazard while maintaining electrical connectivity.
Solution Approach 2:
The bed support section acts as an intermediary that redirects the cable away from the harmful position. Rather than the cable directly traversing above the top panel where it creates obstruction, the bed support section mediates the cable's path, guiding it through a safe route that eliminates the obstruction hazard while preserving the electrical connection between the receiving coil and signal processing section.
