Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label producing apparatuses face challenges in accurately detecting the residual tape amount due to variations in tape thickness and roll diameter, especially when different types of tape cartridges are used, leading to potential inaccuracies in detecting the remaining tape quantity.
Innovation Solution
A label producing apparatus equipped with an optical detecting device that identifies detection marks on a rotating detected body, correlating the tape roll's angular velocity with the residual tape amount, and utilizing type information and parameter tables to calculate the residual tape amount accurately, regardless of tape cartridge type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the angular velocity of the tape roll is detected to detect the residual tape amount, then the residual tape amount can be detected, but the detection accuracy deteriorates when different types of tape cartridges with varying tape thickness and roll diameter are used
Solution Approach 1:
The system dynamically changes the detection parameters (angular velocity thresholds and calculation formulas) based on the detected tape cartridge type. When a tape cartridge is mounted, the system identifies its type and selects the corresponding parameters from stored data, allowing accurate residual tape amount detection across different tape thicknesses and roll diameters without requiring physical measurement of each cartridge.
2Measurement precision
If parameters such as tape thickness and inside roll diameter are required for detection, then the residual tape amount can be calculated, but the system complexity increases due to the need to manage multiple parameters for different cartridge types
Solution Approach 1:
The system automatically acquires and manages the necessary parameters (tape thickness, inside roll diameter, angular velocity data) based on the detected cartridge type. Once the cartridge type is identified, the system self-configures by retrieving the corresponding parameters from stored data, eliminating the need for manual parameter input or complex configuration management by the user.
3Adaptability or versatility
If different types of tape cartridges are used to produce different types of printed labels, then the system versatility is improved, but the residual tape amount detection accuracy deteriorates due to variations in tape thickness and roll diameter
Solution Approach 1:
The system dynamically adapts its detection parameters and calculation methods based on the detected cartridge type. Rather than using fixed detection parameters, the system adjusts the angular velocity thresholds and calculation formulas in real-time according to the specific tape cartridge mounted, enabling both high versatility in producing different label types and maintained detection accuracy across all cartridge variations.
