Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rigid manipulators lack the ability to efficiently and precisely grasp and manipulate objects at varying distances due to fixed reach limitations, which restricts their versatility in space manipulation tasks.
Innovation Solution
The development of an articulated pick-up tool with an adjustable telescopic structure and a remote-controlled clamp, allowing for extended reach and precise object manipulation through a combination of telescopic arms, detents, and a remote control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid manipulator uses a fixed-length structure, then the structure is simple and stable, but the reach and versatility are limited
Solution Approach 1:
The manipulator arm is divided into multiple telescopic segments that can extend and retract relative to each other. Each segment contains internal telescopic mechanisms with detents, allowing the arm to achieve variable lengths while maintaining structural stability when locked at specific positions.
Solution Approach 2:
The manipulator transitions from a fixed-length structure to a dynamically adjustable length structure. The telescopic arms can be extended or retracted based on operational requirements, and the detent mechanisms provide stable locking at various intermediate positions, enabling adaptive reach capability.
2Length of moving object
If a manipulator uses a telescopic structure to extend reach, then the versatility improves, but the structural complexity increases
Solution Approach 1:
The telescopic arms employ a nested configuration where smaller segments are housed within larger segments. This nested arrangement allows multiple telescopic stages to be compactly integrated, extending the reach without proportionally increasing the overall structural complexity or volume.
Solution Approach 2:
The detent mechanisms are designed to automatically engage and lock the telescopic segments at predetermined positions without requiring external actuators for each locking point. This self-locking feature reduces the complexity of control systems while maintaining stable extended positions.
3Adaptability or versatility
If the manipulator arm is extended to reach distant objects, then the operational range increases, but the structural stability may decrease
Solution Approach 1:
The detent mechanisms provide pre-established stable locking positions at various extension lengths. When the telescopic arm is extended to reach distant objects, the detents ensure that the structure settles into predetermined stable configurations, preventing unintended movement or collapse and maintaining structural integrity throughout the extended range.
