Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used to pull cables, then cable movement is achieved, but a large number of workers are required and human error increases
Solution Approach 1:
The patent replaces the manual mechanical pulling system with an automated cable pulling device that uses a spool and controlled winding mechanism. This substitution eliminates the need for multiple workers to manually pull cables, thereby improving productivity while reducing the quantity of human labor required.
Solution Approach 2:
The cable pulling device is designed to autonomously pull cables through the building infrastructure using automated control systems. The device can independently manage the cable pulling process without continuous human intervention, allowing the system to serve itself in performing the cable laying task.
2Productivity
If manual labor is used to pull cables, then cable movement is achieved, but cable damage may occur due to human error
Solution Approach 1:
The automated cable pulling device replaces manual pulling operations, eliminating human error that could lead to cable damage. The controlled spool mechanism ensures consistent, damage-free cable deployment at optimized speeds, simultaneously improving productivity and maintaining cable integrity.
Solution Approach 2:
The system incorporates control systems that monitor the cable pulling process in real-time, adjusting parameters to prevent excessive tension or speed that could damage the cable. This feedback mechanism ensures reliable cable deployment while maintaining efficient productivity.
3Force
If multiple workers pull the cable, then cable movement is achieved, but the risk of cable damage increases
Solution Approach 1:
The automated cable pulling device provides controlled, consistent pulling force through a mechanical spool system, replacing the uncoordinated manual pulling by multiple workers. This ensures adequate force is applied to move heavy cables while maintaining cable safety by preventing excessive or uneven tension.

AI summary
A cable movement system is disclosed. The system may include a first cable pulling device and a second cable pulling device configured to pull a cable disposed between the first cable pulling device and the second cable pulling device, and cause a cable movement on a predefined path. The system may further include a computing unit including a memory and a processor. The memory may be configured to store an information associated with predefined path geometry, and the processor may be configured to determine an optimal rotational speed for conveying wheels associated with the first and/or second cable pulling devices based on the information associated with predefined path geometry. The processor may be further configured to transmit a command signal to a motor associated with the first and/or second cable pulling devices to cause a conveying wheel rotation based on the optimal rotational speed.
