Solution Overview
Problem
Existing robot arm configurations, such as those described in WO2007/034561, are complex and utilize a large number of components, making them difficult to simplify and manufacture efficiently.
Innovation Solution
A module robot design that incorporates a first link, a second link movably linked to the first link, and a fluid pressure cylinder to move the links relative to each other, where the first link features a cylinder block housing the fluid pressure cylinder's chamber, thereby reducing the number of components and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a robot arm is configured with separate arm forming members and arm driving devices, then the robot can achieve motion control, but the structure becomes complex and the number of components increases
Solution Approach 1:
The patent combines the arm forming member and arm driving device into a single integrated link unit. The cylinder block forming the arm member also houses the cylinder chamber, and the piston rod directly connects to the link, eliminating separate driving device components. This merging reduces structural complexity while maintaining motion control functionality.
Solution Approach 2:
The link structure serves multiple functions simultaneously: it forms the mechanical arm structure, houses the fluid pressure cylinder chamber, and provides mounting points for the piston rod and buffer. This multi-functionality reduces the number of separate components needed while maintaining full motion control capability.
2Ease of operation
If separate arm forming members and arm driving devices are used, then motion control is achieved, but the number of components increases
Solution Approach 1:
The patent merges the arm forming member and arm driving device into a single integrated link unit. The cylinder block forming the arm member also houses the cylinder chamber, and the piston rod directly connects to the link, eliminating separate driving device components. This merging reduces the number of components while maintaining motion control functionality.
3Ease of operation
If a complex structure with multiple components is used, then motion control is achieved, but assembly and transportation become difficult
Solution Approach 1:
The robot arm is divided into modular link units, where each link is a self-contained assembly with its own cylinder block, chamber, and piston rod connection. This segmentation allows each module to be manufactured and tested independently, then assembled into the complete robot arm, significantly easing assembly and transportation.
Solution Approach 2:
The patent combines the arm forming member and arm driving device into a single integrated link unit. The cylinder block forming the arm member also houses the cylinder chamber, and the piston rod directly connects to the link, eliminating separate driving device components. This merging reduces structural complexity while maintaining motion control functionality.
