Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispensing and verifying liquid or pasty medium quantities in work processes lack efficient calibration and verification methods that do not interfere with the main transport operations, and are prone to measurement inaccuracies due to vibration and shock.
Innovation Solution
A system with independently movable second transport units that collect medium from dosing devices and measure it using a weighing device decoupled from the work surface, allowing for accurate calibration and verification without disrupting main transport processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a weighing device is integrated into the work surface for calibration, then calibration function is provided, but measurement precision deteriorates due to vibrations and shocks from main transport operations
Solution Approach 1:
The system is divided into two independent parts: the work surface with first transport units for main operations, and a separate weighing device with second transport unit for calibration. This segmentation isolates the sensitive weighing function from vibrations and shocks generated by the main transport operations, thereby maintaining measurement precision while providing calibration capability.
2Adaptability or versatility
If calibration stations are arranged alongside the conveying line, then calibration verification is enabled, but device complexity increases and work area is occupied
Solution Approach 1:
The second transport unit is designed as a universal carrier that can transport both workpieces and measuring cups. The weighing device integrates the measuring cup, load cell, and transport functions into a single multi-functional unit, reducing overall system complexity while maintaining calibration verification capability.
3Measurement precision
If manual intervention is used for calibration, then measurement verification is possible, but productivity decreases due to manual operations
Solution Approach 1:
The system implements automated calibration through the second transport unit that autonomously transports measuring cups to and from the weighing device. The control device coordinates the entire calibration process without manual intervention, maintaining measurement accuracy while significantly improving calibration efficiency and productivity.
4Strength
If the weighing device is coupled to the work surface, then structural support is provided, but measurement precision deteriorates due to transmitted vibrations
Solution Approach 1:
The weighing device is extracted from the work surface structure and positioned as a separate unit. This extraction removes the source of vibrations and shocks from the weighing measurement path, thereby improving weighing accuracy while the weighing device maintains its own structural support independent of the work surface.
