Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough winding devices struggle to wind pieces of dough into wound dough products efficiently, reliably, and gently, often resulting in deformation or unsightly formation of the dough.
Innovation Solution
A device comprising a lower and upper winding unit with shafts and belts, where the first shaft has a small diameter and is supported by rolling bearings to prevent deflection, and the belts move in opposite directions to create a widening gap for gentle winding, with adjustable components for varying dough sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large-diameter shaft is used in the winding device, then the structural strength is improved, but the dough piece undergoes deformation and bends during winding
Solution Approach 1:
The patent applies local quality by using a small-diameter shaft (10-15mm) specifically in the critical winding zone where dough contact occurs, while other structural components maintain adequate dimensions for strength. This localized optimization allows gentle dough handling without compromising overall structural integrity.
2Shape
If the shaft diameter is reduced to minimize dough deformation, then the dough handling quality is improved, but the shaft becomes prone to deflection under belt tension
Solution Approach 1:
The patent applies preliminary action by proactively supporting the small-diameter shaft with bearings before deflection can occur during operation. The bearings are pre-installed on the shaft or shaft support structure to maintain shaft stability and prevent deflection under belt tension throughout the winding process.
3Device complexity
If conventional winding mechanisms are used, then the device complexity is reduced, but the winding reliability and gentleness are insufficient
Solution Approach 1:
The patent applies parameter changes by optimizing the shaft diameter to 10-15mm, which is significantly smaller than conventional shafts. This parameter change enables gentle dough handling and reliable winding while maintaining acceptable device complexity through straightforward bearing support.
4Manufacturing precision
If the winding space gap is reduced for precise control, then the winding precision is improved, but the dough piece may be compressed or deformed
Solution Approach 1:
The patent applies segmentation by dividing the winding process into distinct zones: an initial zone with larger gap for gentle dough entry and shaping, followed by a controlled zone for precise winding. This spatial segmentation allows both gentle handling and precision control without compromising dough shape.
