Robot Base Connector Unit for Cable Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots with multi-articular arms often face interference issues due to numerous power feeding cables, which complicates installation and increases the risk of damage during cable connection.
Innovation Solution
A robot design featuring a base with a body and a connector unit that includes cable connectors to connect internal and external cables efficiently, minimizing interference and damage by routing cables through a cable duct and using tube connectors to manage pneumatic tubes, allowing for adjustable cable connection orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cables are incorporated in the base to avoid interference with multi-articular arms, then cable interference is reduced, but cable connection becomes complex and installation time increases
Solution Approach 1:
The cable connection function is extracted from the base body and concentrated into a dedicated connector unit. This unit can be independently positioned and oriented, allowing cable connections to be made at optimal locations away from the multi-articular arm operation zone, thus reducing interference while simplifying installation procedures
Solution Approach 2:
The base is segmented into functional modules: the main base body supporting the multi-articular arm, and a separate connector unit for cable management. This segmentation allows the connector unit to be optimally positioned and oriented independently, reducing cable interference with arm movement while maintaining organized cable routing
2Object-affected harmful factors
If multiple cables are routed through the base body, then cable interference with multi-articular arms is minimized, but the risk of cable damage during connection increases
Solution Approach 1:
The connector unit serves as an intermediary structure between the base body and external cable connections. It provides a protected environment for cable termination points, shielding them from damage during connection operations while maintaining organized routing that minimizes interference with multi-articular arm movement
Solution Approach 2:
Cables are pre-routed through designated pathways in the base body to the connector unit before final connection. This preliminary routing ensures cables are positioned away from high-risk zones during installation, reducing the likelihood of damage while maintaining optimal positioning for minimizing interference with arm operations
3Object-affected harmful factors
If cable connectors are positioned away from the base opening, then cable management is improved, but connection accessibility and installation efficiency decrease
Solution Approach 1:
The connector unit is designed with adjustable positioning and orientation capabilities, allowing it to be dynamically configured to optimize both cable management within the base and accessibility from outside. This dynamic adjustability enables the connector to serve dual purposes: organized cable routing and efficient connection access

AI summary
A robot includes a multi-articular arm and a base. The base includes a body and a connector unit. The body has a supporting surface and a space. The supporting surface supports a base end portion of the multi-articular arm. The space is provided in the body and has a base opening on the supporting surface. The connector unit is disposed in the space and includes a cable connector that is connectable to an internal cable disposed in the body and that has a connection opening to be connectable to an external cable. The connection opening faces toward the base opening.
