Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough strip systems face inefficiencies in producing pastries with precise weight, leading to increased raw material costs and waste due to manufacturing tolerances, as they struggle to maintain accurate weight accuracy and adjust cutting widths dynamically without stopping production.
Innovation Solution
The device features an adjustable cutting unit with a disc-shaped adjustment mechanism driven by a motor, allowing for rapid adjustments in cutting width without stopping the system, using ramps and return springs to precisely control the knife's position, and a control unit to ensure consistent weight distribution across dough strands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dough conveyor systems use fixed cutting widths, then production stops are required to adjust cutting width, but this reduces productivity and increases costs
Solution Approach 1:
The cutting device incorporates a motor-driven adjustment mechanism that enables dynamic modification of the cutting width during operation. The blade position can be rapidly adjusted (within milliseconds) without stopping the dough conveyor, transforming a static cutting system into a dynamic one that adapts to varying weight requirements while maintaining continuous production
Solution Approach 2:
The system changes the cutting parameter (blade position relative to dough strip) in real-time based on weight measurements. By adjusting the blade position parameter dynamically, the system compensates for weight variations in dough strips, ensuring accurate pastry weights without production interruptions
2Manufacturing precision
If cutting width is precisely set in conventional systems, then weight accuracy of dough pieces improves, but adjustment flexibility is reduced
Solution Approach 1:
The cutting device transitions from a fixed, precisely-set cutting width to a dynamic system where the blade position can be rapidly adjusted during operation. The motor-driven mechanism enables continuous adaptation of cutting width while maintaining precision through controlled movement and positioning
Solution Approach 2:
The system uses weight measurements of dough strips as feedback to automatically adjust the blade position. This closed-loop control ensures that weight accuracy is maintained while providing adaptability to varying dough strip weights, eliminating the trade-off between precision and flexibility
3Productivity
If rapid blade adjustment is implemented, then productivity improves by avoiding production stops, but device complexity increases
Solution Approach 1:
The system replaces manual or mechanical adjustment methods with a motor-driven adjustment mechanism. This substitution enables automated, rapid blade positioning controlled by the control unit, achieving continuous production capability while managing complexity through electrical control rather than complex mechanical linkages

Function Achieved in This Case
This solution significantly improves weight accuracy of dough strands, reduces production costs, and minimizes waste by allowing real-time adjustments during operation, ensuring consistent weight per unit length of cut sections without interrupting the production process.
Implementation Method 1
one, in particular three, ramps are arranged on one of the end faces of the adjustment disc, wherein a ramp receptacle, in particular designed opposite to the ramp, is formed on the knife, wherein the ramp rests against the ramp receptacle, wherein the ramp rises, in particular uniformly, in the direction of the axis of the adjustment disc such that when the adjustment disc is moved, preferably rotated, by the motor, the ramp is moved and the position of the knife relative to the cutting unit is changed
Implementation Method 2
the adjustment mechanism may include at least one, and in particular three, return springs, wherein the return spring is arranged such that it exerts a force on the knife against the slope of the ramp and in particular reduces the distance of the knife to the cutting unit
