Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing workpiece parts from a residual grid of plate-shaped materials are inefficient, often requiring manual handling and additional tools, especially for thicker materials, and lack a reliable and flexible solution for gripping and sorting.
Innovation Solution
A handling device with a housing, handle, and gripping element, powered by an accumulator, featuring either an electromagnet or suction gripper, allowing for easy activation and deactivation of the gripping mechanism, along with a control element and optional camera or data interface for automated data capture and sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling and additional hand tools are used to remove workpiece parts from residual grid, then workpiece parts can be removed from thicker plate-like materials, but the removal process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical handling with an electromagnetic gripping system. The electromagnet in the gripping element generates magnetic fields to hold and transport workpiece parts automatically, eliminating the need for manual handling and additional hand tools, thereby significantly improving removal efficiency and reducing time loss
Solution Approach 2:
The handling device is designed to autonomously grip, lift, and transport workpiece parts from the residual grid without requiring continuous manual intervention. The electromagnet automatically activates to grip the workpiece, transports it to the designated location, and releases it, enabling the system to serve itself in the workpiece removal process
2Ease of operation
If electromagnetic gripping element is used to hold workpiece parts, then gripping and release becomes simple and safe, but energy consumption increases due to continuous power supply requirement
Solution Approach 1:
The electromagnet operates periodically rather than continuously - it is activated only when a workpiece needs to be gripped and transported, and deactivated when no workpiece is present. This periodic operation significantly reduces energy consumption while maintaining simple and safe gripping/release functionality when needed
Solution Approach 2:
The control unit monitors the presence and position of workpiece parts and activates the electromagnet only when necessary. This feedback-controlled operation ensures the electromagnet consumes energy only during actual gripping and transport operations, optimizing energy usage while maintaining operational ease
3Adaptability or versatility
If multiple gripping elements are provided on the handle, then adaptability to different sizes of workpiece parts is improved, but device complexity increases
Solution Approach 1:
The gripping element is divided into multiple independent electromagnetic segments arranged on the handle. Each segment can independently activate to grip workpiece parts of different sizes and shapes, providing adaptability without requiring a completely different device for each workpiece type
Solution Approach 2:
Multiple gripping elements on the single handle serve universal purposes - they can grip various sizes and types of workpiece parts using the same electromagnetic mechanism. This multi-functional design achieves adaptability to different workpiece sizes while maintaining relatively simple device structure compared to having multiple separate tools
