Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines in the tobacco industry often produce defective products and experience unexpected stops due to discontinuities in fluid supplies, such as glue or flavor, leading to rod breakage during the formation process.
Innovation Solution
Incorporating sensor means, like ultrasonic sensors, to detect the presence and size of bubbles in the fluid before supply, allowing for intervention to prevent discontinuities and enabling controlled machine operation to avoid product defects and stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical means are used to separate bubbles from fluid flow, then bubble removal is achieved, but device complexity increases and reliability does not fully improve due to rod breakage
Solution Approach 1:
The patent replaces mechanical bubble separation systems with an optical detection system (light source and sensor). The system uses light transmission through the fluid to detect bubbles optically, eliminating the need for complex mechanical separation apparatus while maintaining reliability by enabling real-time bubble detection and alert mechanisms.
Solution Approach 2:
The patent introduces light as an intermediary substance to detect bubbles in the fluid. The light source emits light through the fluid, and the sensor detects changes in light transmission caused by bubbles, serving as a non-contact intermediary that enables bubble detection without mechanical intervention.
2Manufacturing precision
If continuous fluid supply is maintained, then manufacturing precision improves, but harmful factors increase due to bubble presence causing defects
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously monitors the fluid for bubbles and provides real-time information to a control system. When bubbles are detected, the system can trigger alerts or adjust the fluid supply to prevent defective products, creating a closed-loop control system that maintains manufacturing precision while eliminating bubble-related harmful effects.
Solution Approach 2:
The patent performs preliminary detection of bubbles in the fluid before the fluid reaches the application point. By detecting bubbles upstream in the supply line, the system can take preventive action (such as stopping supply or alerting operators) before bubbles cause defects in the final product, ensuring continuous manufacturing precision.
3Manufacturing precision
If bubble detection is implemented, then product quality improves, but device complexity increases due to additional sensor means
Solution Approach 1:
The patent uses a simple optical detection system consisting of a light source and a sensor, replacing complex mechanical inspection systems. The light transmission method provides reliable bubble detection with minimal mechanical components, improving product quality while adding only minimal device complexity.
