Solution Overview
Problem
The design of cables for robot devices is challenging due to the need to avoid interference with external obstacles, requiring careful consideration of length, curvature, tension, and space efficiency, which is often costly and inefficient, limiting the robot's movable range.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cable length is increased to accommodate robot motion, then the cable can generally fit the robot movement, but the possibility of cable contact with surrounding environment increases and space efficiency is aggravated
Solution Approach 1:
The patent performs preliminary simulation of cable behavior before actual robot operation. By calculating cable positions and detecting potential collisions with obstacles in advance, the system determines safe cable lengths and routing paths, preventing interference issues before they occur in real operation
Solution Approach 2:
The patent implements a feedback mechanism where simulation results of cable behavior are used to adjust and optimize cable length and routing decisions. The collision detection results feed back into the design process to refine cable configuration, creating an iterative optimization loop
2Stability of the object's composition
If the cable length is increased to avoid tension and curvature issues, then the cable can accommodate robot movement, but the robot's movable range is limited by the cable arrangement
Solution Approach 1:
The patent performs preliminary simulation of cable behavior before actual robot operation. By calculating cable positions and detecting potential collisions with obstacles in advance, the system determines safe cable lengths and routing paths, preventing interference issues before they occur in real operation
Solution Approach 2:
The patent models cable behavior dynamically as the robot moves through its workspace. The simulation calculates cable positions, tensions, and curvatures for different robot configurations, allowing optimization of cable length to balance tension stability with maximum robot mobility
3Ease of manufacture
If manual cable wiring design is performed with intuition and experimental rules, then the design can be completed, but the process is costly and has high personal dependency
Solution Approach 1:
The patent replaces manual intuition-based design with automated computer simulation and calculation. The system uses computational algorithms to model cable behavior, detect collisions, and optimize wiring paths, eliminating dependence on human expertise and experimental trial-and-error
Solution Approach 2:
The patent creates a virtual copy of the cable system in simulation environment. By modeling and testing cable behavior in the virtual space before physical implementation, the system eliminates costly physical prototyping and experimental adjustments

AI summary
An information processing method includes an output step in which a control device outputs a wire model having a length and a fixed position that satisfy a predetermined condition based on an initial value of at least one fixed position where a wire wired outside of a movable unit is fixed, an initial value of the length of the wire, and search conditions including physical constraints imposed on the wire associated with a move of the movable unit.
