Multi-Axis Robot Carriage for Cable Length Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-axis robotic systems for medical examination and treatment devices require complex and costly lead storage systems in the ceiling, which are difficult to assemble, maintain, and clean due to the need for additional fixings and suspensions, and result in excessive cable length.
Innovation Solution
Integration of a carriage arrangement with deflection rollers and restoring elements on the articulated arm, allowing the lead store to be moved with the robotic system, reducing the need for ceiling-mounted infrastructure and simplifying assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a ceiling-mounted lead storage system is used to provide sufficient cable length for multi-axis robot movement, then the required cable reserve is available, but the device complexity and assembly/maintenance cost increase due to additional ceiling fixings and suspensions
Solution Approach 1:
The lead storage system is extracted from the ceiling infrastructure and integrated directly onto the articulated arm. The carriage arrangement with deflection roller and restoring element allows the lead store to be carried along by the robot itself, eliminating the need for ceiling-mounted reservoirs and complex suspension systems.
Solution Approach 2:
The lead storage function is merged with the articulated arm structure. The carriage arrangement is integrated onto the articulated arm, combining the lead storage capability with the robot's existing mechanical structure, thereby eliminating separate ceiling-mounted lead stores and their associated fixings.
2Quantity of substance
If ceiling-mounted lead storage systems are installed to ensure sufficient cable length, then cable reserve is adequate, but ease of manufacture and installation deteriorate due to complex assembly requirements
Solution Approach 1:
The lead storage system is extracted from the ceiling infrastructure and integrated directly onto the articulated arm. The carriage arrangement with deflection roller and restoring element allows the lead store to be carried along by the robot itself, eliminating the need for ceiling-mounted reservoirs and complex suspension systems.
3Quantity of substance
If ceiling-mounted lead storage systems are used to provide sufficient cable length, then cable reserve is adequate, but ease of operation and maintenance worsen due to difficult cleaning and access requirements
Solution Approach 1:
The lead storage system is extracted from the ceiling infrastructure and integrated directly onto the articulated arm. The carriage arrangement with deflection roller and restoring element allows the lead store to be carried along by the robot itself, eliminating the need for ceiling-mounted reservoirs and complex suspension systems.
Solution Approach 2:
The lead storage system on the articulated arm is more accessible for maintenance and cleaning operations. The carriage arrangement can be easily accessed when the robot is in position, allowing maintenance personnel to service the lead store without requiring complex ceiling access procedures.
4Quantity of substance
If ceiling-mounted lead storage systems are installed to ensure sufficient cable length, then cable reserve is adequate, but loss of time increases due to excessive cable length requiring management
Solution Approach 1:
The lead storage system transitions from a static ceiling-mounted reservoir to a dynamic carriage arrangement that moves with the articulated arm. The restoring element automatically manages cable tension and payout, eliminating the need for manual cable management and reducing time losses associated with excessive cable length.
