Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot gripper systems face challenges in cost and space efficiency due to the need for multiple tools for various objects, and adaptive grippers have limited work range based on their size and performance.
Innovation Solution
A finger-gripper assembly system that allows for the removable connection of fingers to a gripper, featuring a rotatable extender and movable connector, enabling efficient coupling and decoupling without replacing the entire gripper, and a storage station for fingers, reducing the need for multiple tools and simplifying the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire tool is replaced to grip various objects, then the gripping capability for different objects is improved, but the cost and storage space requirements increase
Solution Approach 1:
The tool is divided into two separable parts: a gripper body and interchangeable fingers. Instead of replacing the entire tool, only the finger portion needs to be changed to adapt to different objects. The mounting hole and connector mechanism enable easy segmentation and recombination of these parts.
Solution Approach 2:
The gripper body is designed as a universal platform that can accommodate multiple types of fingers through the standardized mounting interface. This allows one gripper to perform multiple gripping functions by simply changing the finger attachment, eliminating the need for multiple complete tools.
2Adaptability or versatility
If the entire tool is replaced to grip various objects, then the gripping capability for different objects is improved, but the cost increases
Solution Approach 1:
By segmenting the tool into a reusable gripper body and interchangeable fingers, the manufacturing cost is distributed. The expensive gripper body is made once and reused, while cheaper fingers are manufactured in varieties as needed, reducing overall system cost.
Solution Approach 2:
The design allows for easy discarding of worn or damaged fingers and recovering the expensive gripper body for continued use. This extends the lifecycle of the main tool component and reduces long-term manufacturing costs.
3Reliability
If an adaptive gripper with flexible mechanism is used, then the gripping effect is improved, but the range of work is limited by the gripper size and performance
Solution Approach 1:
The standardized mounting interface creates a universal system where the same gripper body can work with different finger types suited for different tasks, expanding the range of work beyond what a single fixed gripper design could achieve.
Solution Approach 2:
The system allows dynamic reconfiguration of the gripping mechanism by changing fingers based on task requirements, enabling the gripper to adapt its characteristics rather than being fixed to a single performance profile.

AI summary
The present disclosure relates to a finger-gripper assembly and a finger-gripper assembly system including the same. The finger-gripper assembly includes a finger and a gripper to which the finger is coupled so as to be removable. The gripper includes an arm, an extender coupled to a lower end of the arm so as to be rotatable about a first axis, wherein the extender extends, from the arm along a second axis that extends in an extension direction and intersects with the first axis, and a connector coupled to a lower side of the extender so as to be movable along the second axis, wherein the connector is connectable to the finger.
