Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel dividing systems face challenges in simplifying and automating the handling of workpieces, particularly stacks of workpieces on a support table, as they require manual operation and limited directional movement, which can lead to inefficiencies and increased risk of damage during handling and positioning.
Innovation Solution
A panel dividing system equipped with a handling device that includes a base structure with movable feed sections and suction devices, allowing for movement in multiple directions and orientations, along with a control system that adjusts suction power based on workpiece size and surface roughness, enabling precise and flexible handling of individual and stacked workpieces without the need for predetermined indentations or collet grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of workpieces on a support table is used, then operational flexibility is maintained, but handling efficiency and productivity are reduced
Solution Approach 1:
The handling device automatically positions and orients workpieces using its own integrated positioning devices and sensors, without requiring external manual intervention. The device serves itself by detecting workpiece characteristics and autonomously adjusting handling parameters, thereby improving productivity while maintaining operational flexibility through programmable adaptability.
Solution Approach 2:
The system changes handling parameters such as suction force, positioning device extension, and motion speed based on detected workpiece properties like size, weight, and surface characteristics. This allows automated handling to adapt to different workpieces, maintaining flexibility while achieving high productivity through consistent automated operations.
2Adaptability or versatility
If movement is restricted to predetermined directions only, then device structure is simplified, but handling versatility and adaptability are reduced
Solution Approach 1:
The handling device incorporates dynamically adjustable components including extendable positioning devices that can reach different locations, variable suction force application, and programmable motion paths that are not limited to fixed directions. This dynamic capability enables versatile handling of workpieces in various orientations and positions while managing structural complexity through controlled flexibility rather than rigid multi-directional mechanisms.
Solution Approach 2:
The handling device is designed as a universal system that can handle different types of workpieces (individual pieces, stacks, various sizes and orientations) using the same base structure with programmable positioning and motion control. This multi-functionality achieves handling versatility without requiring separate specialized devices for each handling scenario, thereby managing device complexity through consolidation.
3Productivity
If suction force is increased to handle larger or heavier workpieces, then handling capability is improved, but risk of surface damage increases
Solution Approach 1:
The system dynamically adjusts suction force parameters based on detected workpiece properties such as weight, surface material, and orientation. For heavier workpieces, higher suction force is applied, while for workpieces with sensitive surfaces, the suction force is reduced and distributed across multiple contact points. This parameter adaptation enables strong handling capability while minimizing surface damage risk through intelligent force management.
Solution Approach 2:
The suction force is segmented and distributed across multiple suction cups or contact points rather than concentrated at a single location. This segmentation allows the total required holding force to be divided into smaller, less damaging local forces, enabling handling of heavy workpieces without causing surface damage at any single contact point.
4Measurement precision
If positioning devices are extended to contact workpiece edges, then positioning precision is improved, but risk of workpiece damage increases
Solution Approach 1:
The positioning devices are designed with cushioning elements such as soft tips, elastic components, or damping mechanisms that absorb impact forces during contact with workpiece edges. This beforehand cushioning protects fragile workpiece edges from damage while still enabling precise positioning through controlled contact, resolving the contradiction between positioning precision and damage prevention.
Solution Approach 2:
The system adjusts the contact force parameter of positioning devices based on workpiece characteristics and positioning requirements. For fragile workpieces, minimal contact force is applied just sufficient for positioning, while for robust workpieces, higher force can be tolerated. This parameter adaptation enables precise positioning while minimizing damage risk through force optimization.
