Robot Base Connector Waterproofing via Shielding Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot designs require complex structures to provide a waterproof function for power feed cable coupling connectors, which increases complexity and cost.
Innovation Solution
A robot design featuring a base with a housing, a connector unit on its side surface, a cover member with an insertion portion for the cable, and a shielding part that projects from the side surface to prevent liquid from reaching the connector unit, eliminating the need for specialized waterproof connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof connector and waterproof cable are used to provide waterproof function, then the waterproof function is achieved, but the structure becomes complex
Solution Approach 1:
The waterproofing function is segmented between the cover member (providing external protection) and the wall portion (providing internal shielding), allowing standard connectors to be used while achieving waterproof效果 through structural division rather than requiring specialized waterproof connectors
Solution Approach 2:
The wall portion acts as an intermediary element between the coupling portion and the connector unit, creating a physical barrier that prevents liquid intrusion without requiring the connector itself to have waterproof capabilities, thus simplifying the overall structure
2Reliability
If a waterproof connector and waterproof cable are used to provide waterproof function, then the waterproof function is achieved, but the cost increases
Solution Approach 1:
The wall portion is implemented as a simple, inexpensive structural element (likely a plastic or metal barrier) rather than using expensive waterproof connectors and specialized cables, achieving cost-effective waterproof protection through simple structural design
Solution Approach 2:
The waterproofing function is achieved by copying the protective function from specialized waterproof connectors to a simpler structural configuration using the cover member and wall portion, eliminating the need for expensive proprietary waterproof components

AI summary
A robot includes a robot arm, a base supporting the robot arm, and a cable coupled to the base, wherein the base has a housing a circuit board, a connector unit located on a side surface of the housing and electrically coupled to the circuit board, to which the cable is coupled, a cover member having an insertion portion through which the cable is inserted and attached to the side surface of the housing to cover the connector unit, and a wall portion located between a coupling portion by which the cover member is coupled to the side surface of the housing and the connector and provided to project from the side surface of the housing within a space surrounded by the side surface of the housing and the cover member.
