Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food slicing devices struggle to consistently slice blocks of varying sizes and consistencies, as the cross-section and composition of food blocks can change, leading to suboptimal slicing quality.
Innovation Solution
A method using a vibration sensor to detect vibrations generated when the cutting blade interacts with the food block, adjusting the rotational speed, orbital speed, and position of the cutting blade, as well as the portioning process, to adapt to the consistency and size of the food block, ensuring optimal slicing and portioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cutting blade operates at constant speed, then the slicing process is simple and stable, but the slicing quality deteriorates when food block consistency varies
Solution Approach 1:
The system uses vibration sensors to detect vibrations generated during cutting and feeds this information back to the controller, which automatically adjusts cutting parameters. This closed-loop feedback mechanism enables the system to adapt to varying food block consistencies while maintaining slicing quality without requiring complex manual intervention.
Solution Approach 2:
The cutting system transitions from static constant-speed operation to dynamic variable-speed operation. The rotational speed of the cutting blade and feed rate of the food block are continuously adjusted based on real-time vibration analysis, allowing the system to optimize slicing quality for different food consistencies.
2Manufacturing precision
If manual adjustments are made for different food blocks, then slicing quality can be optimized, but productivity decreases due to frequent interventions
Solution Approach 1:
The system performs self-adjustment through automatic vibration-based detection and control. The controller autonomously modifies cutting parameters based on sensor data without requiring operator intervention, enabling the system to maintain optimal slicing quality across different food blocks while maximizing productivity.
Solution Approach 2:
Manual mechanical adjustment is replaced by an automated sensor-based control system. Vibration sensors and a controller substitute for human operators in detecting food block characteristics and adjusting cutting parameters, thereby eliminating the trade-off between quality optimization and productivity.
3Productivity
If the cutting blade speed is increased for high productivity, then throughput improves, but slicing quality deteriorates for softer or harder foods
Solution Approach 1:
The system dynamically changes cutting parameters including rotational speed, feed rate, and blade depth based on detected food block characteristics. Vibration analysis enables real-time parameter optimization, allowing high-speed cutting for hard foods and reduced speed for soft foods, thereby maintaining slice consistency across varying productivity requirements.
4Adaptability or versatility
If vibration detection is used to adjust cutting parameters, then slicing quality improves for varying food blocks, but device complexity increases
Solution Approach 1:
The vibration-based detection system serves multiple functions: identifying food block consistency, determining optimal cutting speed, detecting block position, and monitoring cutting quality. This multi-functional sensor system achieves high adaptability while minimizing the addition of separate dedicated devices for each function.

AI summary
The slicing method involves separating food slices (6) from a food bar (3) using a cutting knife (2) of a slicing device (1), where a vibration sensor (8) is provided, which receives vibrations generated during impinging of the cutting knife on the food bar, during the entry of the cutting knife into the food bar or during cutting of the food bar. A signal (10) of the vibration sensor is used for setting slicing process or portioning process, where drive of the cutting knife or the orbital movement of the cutting knife is set. The position of the cutting knife is set in x- or y-direction.
