Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough roller devices face challenges in controlling the flow and structure of dough, particularly when processing different types of dough, as they struggle to adjust parameters such as scraper position, gap size, and roller alignment to achieve optimal thickness and strength, leading to potential damage and quality issues.
Innovation Solution
The dough roller device features adjustable roller pairs, allowing for precise control of dough flow by adjusting the relative position of the second roller pair with respect to the first, including transverse and horizontal adjustments, and utilizing separate driving gears for each roller to match surface velocity, along with a third roller pair for thickness control and a scraping system to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the scraper position and gap size are adjusted to control dough flow, then the thickness and strength of the dough strip can be controlled, but the device complexity increases and adjustment becomes difficult
Solution Approach 1:
The patent makes the second roller pair horizontally displacable relative to the first roller pair, allowing dynamic adjustment of the dough passage gap. This enables easy control of dough flow and thickness without complex adjustment mechanisms, as the rollers can be simply shifted horizontally to achieve the desired gap size.
Solution Approach 2:
The patent changes the horizontal position parameter of the second roller pair relative to the first roller pair to control the dough passage gap. By adjusting this positional parameter, the gap size and consequently the dough flow characteristics can be controlled, simplifying the adjustment process while maintaining precision.
2Manufacturing precision
If the scraper position is adjusted to control dough flow, then the dough thickness can be controlled, but the time required for adjustment increases
Solution Approach 1:
The horizontal displacability of the second roller pair allows for quick and simple adjustment of the dough passage gap. Operators can rapidly change the gap size by simply shifting the rollers horizontally, significantly reducing the adjustment time compared to traditional fixed or complex adjustment mechanisms.
3Productivity
If gravity acts on the dough between roller pairs, then the dough flows downward, but the dough structure changes and quality deteriorates
Solution Approach 1:
The patent introduces a horizontal displacement mechanism that counteracts the vertical gravitational flow of dough. By positioning the second roller pair horizontally relative to the first, the system creates a horizontal dough passage that prevents vertical stretching and structural degradation caused by gravity, while maintaining continuous dough flow.
4Device complexity
If the second roller pair is positioned directly below the first, then the device structure is simple, but the dough flow cannot be effectively controlled for different dough types
Solution Approach 1:
The patent makes the second roller pair horizontally displacable relative to the first roller pair, transforming a static structure into a dynamic one. This allows the device to adapt to different dough types by adjusting the horizontal position of the second roller pair, thereby controlling the dough passage gap and flow characteristics for optimal processing of various dough properties.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables easy adjustment for different dough types, minimizing structural changes and ensuring consistent quality by decelerating and deflecting dough flow, reducing stretching and extending, and maintaining the integrity of the dough during processing.
Implementation Method 1
The dough leaving the first roller pair will move downwards from the passage by gravity
Implementation Method 2
By adjusting the mutual position, such as to situate one of the rollers of the second roller pair more, or less, below the passage, the amount of deflection of the flow of the dough coming out of the passage can be adjusted
