Robot Wrist Conduit Pull-In Rope for Post-Installation Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots require extensive and difficult post-installation wiring of wire bodies in narrow spaces between conduits, necessitating removal of pre-installed work tools and conduits, which is cumbersome and inefficient.
Innovation Solution
A robot design incorporating a flexible conduit and a pull-in rope system, where the pull-in rope is detachably fixed to the conduit and work tool, allowing easy connection and detachment of a second wire body without requiring extensive disassembly, using a connection member and nylon bands for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wire bodies are wired within narrow spaces between conduits during post-installation, then wiring flexibility is improved, but operation difficulty increases and extensive disassembly is required
Solution Approach 1:
The patent applies preliminary action by pre-installing a pull-in rope within the conduit during manufacturing, before the actual wire body wiring is needed. This pull-in rope is positioned in advance to facilitate future wire body installation. When post-installation wiring is required, the pre-positioned pull-in rope enables easy wire body insertion through the narrow space without requiring disassembly of the conduit or other components, thus resolving the contradiction between wiring flexibility and operation difficulty.
2Ease of manufacture
If extensive disassembly of pre-installed work tools and conduits is performed for wiring, then wire body installation becomes possible, but installation time increases and productivity decreases
Solution Approach 1:
The pull-in rope is installed during the manufacturing phase as a preliminary action, creating a facilitation mechanism that will be used much later during post-installation wiring. This advance preparation eliminates the need for time-consuming disassembly operations when wiring is actually needed, thereby improving wiring ease without sacrificing productivity.
Solution Approach 2:
The pull-in rope serves as an intermediary element that mediates between the conduit structure and the wire body installation process. Instead of directly manipulating wire bodies through narrow spaces or disassembling conduits, the pull-in rope acts as a intermediary tool that can be easily manipulated from outside the conduit to pull wire bodies through the conduit, significantly reducing installation time and improving productivity.
3Ease of operation
If pull-in rope is positioned within conduit for easy wire body wiring, then operation ease is improved, but device complexity increases
Solution Approach 1:
The pull-in rope serves multiple functions: it facilitates wire body insertion, can be used to retrieve wire bodies, and can assist in conduit maintenance operations. By making this single element multi-functional, the patent improves wiring operation ease without adding multiple separate components, thus avoiding significant increases in device complexity.
Solution Approach 2:
The conduit structure is designed to be self-service capable through the inclusion of the pull-in rope, which enables users to perform wiring operations independently without requiring specialized tools or extensive disassembly. The pull-in rope allows end-users to easily install and maintain wire bodies themselves, improving operation ease while keeping the overall device structure relatively simple.
