Robot Module Coupling Structure for Fast Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coupling multiple modules of robots requires a significant amount of time, which delays the activation of the robot system.
Innovation Solution
A coupling structure that uses a rod-shaped dowel member with insertion portions and fixing means, such as hydraulic pressure or tapered clamps, to easily connect and secure two members by applying external force, allowing for efficient assembly and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling methods are used to connect multiple robot modules, then the connection strength and reliability are improved, but the coupling time and assembly duration increase significantly
Solution Approach 1:
The coupling structure is divided into separate functional components: a rod-shaped part for insertion, fixing means for securing, and external force application mechanisms. This segmentation allows each component to be optimized independently and enables faster assembly by eliminating the need for complex multi-step fastening operations.
Solution Approach 2:
The rod-shaped part is pre-configured with insertion portions that fit into holes of the modules. The fixing means is pre-arranged to apply external force in a predetermined manner, eliminating the need for on-site adjustment or complex alignment procedures during assembly.
2Strength
If traditional fastening methods are used to secure robot modules, then the structural strength is improved, but the assembly complexity and operation difficulty increase
Solution Approach 1:
The fixing means automatically applies external force to the rod-shaped part when the modules are coupled, creating a self-securing mechanism. The structure itself provides the means for its own fixation, eliminating the need for additional fastening operations or complex assembly procedures.
Solution Approach 2:
Traditional mechanical fastening systems (bolts, nuts, screws) are replaced with a simplified system that uses external force application through the fixing means. This substitution reduces assembly complexity while maintaining structural integrity.
3Productivity
If modular robot systems are designed for easy assembly, then the assembly speed is improved, but the connection reliability and structural stability may be compromised
Solution Approach 1:
The external force applied by the fixing means can be adjusted to optimize the balance between assembly speed and connection reliability. By controlling the magnitude and direction of the external force, the system achieves both fast assembly and secure connections.
Solution Approach 2:
The rod-shaped part with insertion portions serves multiple functions: it provides structural connection, enables alignment, and works with the fixing means to secure the modules. This multi-functionality reduces the number of components needed while maintaining connection reliability.

AI summary
A coupling structure for coupling a first member and a second member includes a rod-shaped part configured to be received across a first hole formed in the first member and a second hole formed in the second member. The rod-shaped part has a first insertion portion configured to be inserted into the first hole of the first member, and a second insertion portion configured to be inserted into the second hole of the second member. The coupling structure further includes a fixing configuration, the fixing configuration being configured to fix the first insertion portion and the first member by applying an external force to the first insertion portion, and the fixing configuration being configured to fix the second insertion portion and the second member by applying an external force to the second insertion portion.
