Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dough and semi-viscous material feeding systems for portioning machines face issues such as inconsistent flow, waste, and increased labor due to manual handling, leading to variations in portion size and reduced production efficiency, especially in medium to large-scale operations.
Innovation Solution
A device with a hopper and conveyor system that uses adjustable feed rollers and conveyor belts to control the output flow of dough or semi-viscous material, allowing for consistent slab formation and easy disassembly for cleaning, featuring sensors to monitor hopper levels and adjust feed rates for optimal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bulk discharge systems are used to transfer large quantities of dough quickly, then productivity increases, but portion consistency deteriorates due to head pressure variations
Solution Approach 1:
The system dynamically adjusts the dump gate opening based on real-time hopper level detection. When the hopper is full, the gate opens wider to maximize discharge rate; when the hopper level drops, the gate closes to maintain consistent head pressure. This dynamic adjustment resolves the contradiction by allowing high productivity during filling while maintaining portion consistency during discharge.
Solution Approach 2:
A level detection system provides feedback about the hopper fill state to the control mechanism. This feedback loop enables the system to automatically adjust the dump gate position to maintain optimal hopper levels, ensuring consistent head pressure and portion weight while maximizing overall productivity through rapid refilling cycles.
2Device complexity
If manual handling of dough is used, then equipment complexity is reduced, but labor requirements and time consumption increase
Solution Approach 1:
The feeding system is segmented into distinct functional zones: a bulk storage tote, a controlled discharge mechanism with adjustable gate, and a receiving hopper. This segmentation allows automated high-speed transfer while keeping each component relatively simple in design, reducing overall complexity compared to fully automated continuous feeders while dramatically cutting labor time.
3Productivity
If the dump gate opening is increased to speed up discharge, then productivity improves, but portion consistency deteriorates due to increased head pressure
Solution Approach 1:
The dump gate opening is made dynamic rather than fixed. The system automatically varies the gate position based on hopper fill level: wide opening when refilling to maximize productivity, restricted opening during discharge to maintain consistent head pressure and portion weight. This resolves the contradiction by applying different discharge rates at different operational phases.
4Ease of operation
If hopper levels are allowed to vary widely, then device operation is simplified, but portion size variation increases
Solution Approach 1:
The system performs self-regulation of hopper levels through automated level detection and dump gate control. The device monitors its own hopper fill state and automatically adjusts discharge to maintain optimal levels, eliminating the need for manual intervention while ensuring consistent portion weights. This resolves the contradiction by automating the control function that would otherwise require operator attention.
