Robot Arm Cover Structure for Quick Maintenance Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing robots, it is difficult for operators to recognize the boundary between the arm base and the cover, making it challenging to perform the detachment operation of the cover effectively.
Innovation Solution
The robot design includes a cover with a cover main body that covers the upper portion of the arm base and a covering section that protrudes downward to cover a portion of the side surface, featuring a slit and a wide opening section to facilitate easy attachment and detachment, along with a first portion for easy gripping, and screws for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the cover is made detachable for maintenance access, then ease of repair is improved, but the difficulty of recognizing the boundary between arm base and cover increases
Solution Approach 1:
The cover is designed with a color difference between its upper surface and lower surface. The upper surface has a first color while the lower surface has a second color that is different from the first color. This color differentiation creates a visual boundary that helps operators easily recognize where the cover begins and where the arm base ends, solving the problem of boundary recognition while maintaining the detachable design for maintenance access.
2Reliability
If the cover protrudes downward to cover the side surface, then protection of internal components is improved, but the complexity of the cover structure increases
Solution Approach 1:
The cover is divided into distinct functional segments: an upper surface portion that covers the upper part of the arm base, a lower surface portion that covers the side surface, and a protruding portion that extends downward. This segmentation allows each portion to perform its specific protective function while maintaining overall structural simplicity. The segmented design provides comprehensive coverage without requiring complex integrated structures.
3Ease of operation
If the cover is made detachable with a slit and wide opening, then ease of operation for detachment is improved, but the strength of the cover may be compromised
Solution Approach 1:
The cover includes a slit that divides the cover into separable portions, allowing easy detachment while maintaining structural integrity. The slit is strategically positioned to enable manual separation without compromising the overall strength of the cover when assembled. The wide opening section provides additional access while the segmented design allows the cover to be easily detached for maintenance and reattached securely afterward.

AI summary
A robot includes a base; a first arm rotatably connected to the base around a first rotation axis; and a second arm rotatably connected to the first arm around a second rotation axis parallel to the first rotation axis, wherein the second arm includes an arm base and a cover configured to attach to and detach from the arm base and the cover includes a cover main body that covers an upper portion of the arm base and a covering section that protrudes downward from the cover main body and that covers a portion of a side surface of the arm base.
