Solution Overview
Problem
Current grippers for robots are often limited to single functions, require additional components like servo drivers or pneumatic valve units, increasing size, weight, and complexity, and lack integrated control systems for efficient multi-functional operations.
Innovation Solution
An integrated gripper system combining a servo gripper finger member, pneumatic member, and vision member, controlled by a kernel processor, which includes a motor-driven servo actuator, vacuum generator, and camera for object detection, allowing for compact, multi-functional, and intelligent control of gripping, suction, and visual supervision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a servo gripper is used to achieve precise control, then control accuracy is improved, but device complexity increases due to separate drive modules
Solution Approach 1:
The patent combines the servo motor, drive module, and gripper mechanism into a single integrated unit. The servo motor directly drives the gripper fingers through an integrated transmission mechanism, eliminating the need for separate drive modules and reducing overall system complexity while maintaining precise control capability.
Solution Approach 2:
The integrated gripper design makes the drive mechanism serve multiple functions: it provides both the gripping action and the positioning control, while also integrating the motor mounting and transmission functions. This multi-functionality reduces the number of separate components needed in the system.
2Weight of moving object
If pneumatic grippers are used to reduce size and weight, then portability is improved, but control precision deteriorates as force and position cannot be controlled
Solution Approach 1:
The patent replaces the pneumatic actuation system with a direct-drive servo motor mechanism. This mechanical/electrical system provides precise control over gripping force and finger position through electronic feedback and control algorithms, eliminating the imprecision inherent in pneumatic systems while maintaining compact dimensions.
3Adaptability or versatility
If multiple separate components are used to achieve multi-functionality, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functional components into a single integrated gripper unit. The servo motor, transmission mechanism, gripper fingers, and control electronics are combined into one compact assembly that can perform gripping, positioning, and force control functions simultaneously, reducing the number of separate components needed.
Solution Approach 2:
The integrated gripper is designed with universal functionality to handle various object types and sizes. The servo-controlled fingers can adapt their grip strength and positioning to accommodate different tasks, making the single device capable of performing multiple functions that would otherwise require separate specialized components.
