Dual-System Gripper Sensor Redundancy for Safe Object Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-system grippers lack operational safety and reliability, particularly in monitoring the gripping process and ensuring redundancy in case of sensor failure.
Innovation Solution
A dual-system gripper equipped with at least two gripping object sensors, each measuring different physical quantities, to verify the gripping position and ensure safe pickup, with redundant sensors allowing continued operation even if one fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two gripping devices of different physical operating principles are arranged in the same housing system, then operational safety and reliability are improved through redundancy, but device complexity increases
Solution Approach 1:
The gripping device is segmented into two independent gripping devices (magnetic gripping device and suction gripping device) that can operate independently within the same housing system. Each gripping device has its own gripping object sensor, allowing them to function as separate redundant units while sharing a common housing structure.
Solution Approach 2:
The housing system is designed to accommodate multiple types of gripping devices with different operating principles (magnetic and suction) within a single universal structure. The housing system can support alternative or simultaneous operation of different gripping devices, providing multi-functionality and redundancy.
2Reliability
If gripping object sensors are arranged on or in the housing system to monitor gripping position, then gripping reliability is improved through continuous monitoring, but device complexity increases
Solution Approach 1:
The gripping object sensors are integrated into the housing system structure rather than being separate external components. The sensors are arranged on or in the housing system, combining the monitoring function with the structural housing to reduce overall complexity while maintaining reliable gripping position detection.
Solution Approach 2:
The housing system serves multiple functions: it provides structural support, houses the gripping devices, and integrates the gripping object sensors for monitoring. This multi-functional design reduces the need for separate dedicated sensor housings or mounting structures.
