Solution Overview

Problem

Existing food processing devices struggle to accurately control the weight and composition of multi-type portions, leading to inaccuracies in the final product due to tolerances in the weight of partial portions produced by individual slicing machines.

Innovation Solution

A food processing device comprising at least two slicing devices with sensor assemblies to determine properties like weight, density, and volume, and a control device that adjusts the operation of the slicing devices to achieve precise weight adjustments of partial portions, allowing for accurate combination into multi-type portions. This includes synchronizing slicing operations and using buffering devices to ensure precise alignment and combination of partial portions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple slicing devices are used to produce multi-type portions, then productivity is improved, but manufacturing precision deteriorates due to accumulating weight tolerances

Engineering Contradiction:
Improveproduction outputVSAvoidweight accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system measures the actual weight of each partial portion produced by slicing devices and uses this feedback information to control subsequent slicing operations. The control device adjusts slicing parameters based on measured weights to compensate for tolerances and achieve accurate target weights in multi-type portions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes slicing parameters such as slice thickness and number of slices based on measured properties of partial portions. By adjusting these parameters in real-time, the system compensates for weight variations and ensures accurate final portion weights despite using multiple slicing devices.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If sensor assemblies measure properties of partial portions, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improveweight control accuracyVSAvoidsystem structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical weight adjustment mechanisms with sensor-based measurement and electronic control. Instead of using complex mechanical systems to precisely control weights, the patent uses sensors to measure partial portion properties and electronically controls slicing parameters to achieve the desired weight accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If slicing operations are synchronized, then productivity is improved, but ease of operation deteriorates due to coordination requirements

Engineering Contradiction:
ImprovethroughputVSAvoidoperation coordination
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system uses automatic control devices that autonomously coordinate the slicing operations of multiple devices based on measured properties of partial portions. The control system self-regulates the synchronization without requiring manual intervention or complex operator coordination, maintaining ease of operation while achieving high productivity.

Inventive Principle:
Principle #25Self-service
