Multi-axis Robot Arm With Telescopic Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-axis robot arms have a fixed arm module length, limiting their usage scope and restricting their application to specific situations, as they cannot adapt to varying needs.
Innovation Solution
Incorporating telescopic arm modules with a telescopic tube and shaft, allowing the arm module length to be adjusted by axial extension or retraction, and secured using fastening elements, enabling the robot arm to accommodate different usage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a constant length structure is used for the arm module, then the structure is simple and easy to manufacture, but the usage scope is severely restricted
Solution Approach 1:
The arm module transitions from a fixed constant length structure to a dynamic telescopic structure that can adjust its length. The telescopic arm module includes a telescopic tube and telescopic shaft that can extend and retract, allowing the robot arm to adapt to different usage scenarios while maintaining structural simplicity through standardized telescopic mechanisms.
Solution Approach 2:
The length parameter of the arm module is made variable through the telescopic mechanism. The telescopic shaft can be positioned at different extension levels within the telescopic tube, and fastening elements secure it at specific positions, enabling the same arm module to serve multiple functions across different application scenarios.
2Adaptability or versatility
If a telescopic arm module is introduced to vary the length, then the usage scope is improved, but the device complexity increases
Solution Approach 1:
The telescopic shaft is nested within the telescopic tube, with the shaft projecting into the tube's interior space. This nested configuration allows the arm module to achieve variable length functionality while minimizing the overall space occupation and reducing structural complexity compared to alternative extension mechanisms.
Solution Approach 2:
The arm module is segmented into distinct functional components: the telescopic tube, telescopic shaft, and fastening elements. This segmentation allows for independent manufacturing, assembly, and maintenance of each component, simplifying the overall device complexity while enabling the telescopic functionality required for expanded usage scope.
3Adaptability or versatility
If the telescopic shaft is made adjustable to different positions, then the versatility is enhanced, but the fastening and securing mechanism becomes more complex
Solution Approach 1:
The fastening elements are designed to be simple securing mechanisms that rely on basic mechanical engagement between the telescopic shaft and telescopic tube. The system uses straightforward fastening and unfastening actions without requiring complex locking mechanisms, automated systems, or multiple securing components, thereby enhancing versatility while keeping the fastening mechanism simple.
