Solution Overview

Problem

Existing methods for processing expandable or expanded polymer particles to form particle foam components rely heavily on operator experience, leading to variability and a lack of comprehensive analysis, which limits process optimization and quality improvement.

Innovation Solution

A method involving a data processing unit that receives and evaluates parameter data sets to adjust process parameters automatically, using algorithms to identify deviations from evaluation criteria and compensate for them, thereby optimizing the processing of expandable or expanded polymer particles into high-quality particle foam components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If operator-based manual setting of process parameters is used, then particle foam components of desired quality can be produced, but the process lacks comprehensive analysis and automation

Engineering Contradiction:
Improveparameter setting automationVSAvoidcomprehensive process analysis
Core Design Contradiction:
Extent of automationVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where sensor data from the processing apparatus is continuously fed to a data processing unit. The unit evaluates the data against target values, identifies deviations, and automatically adjusts process parameters. This closed-loop feedback system enables comprehensive process analysis and automation while maintaining quality standards.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical/manual system of operator-based parameter setting with an automated electronic control system. Sensors, data processing units, and actuators work together to automatically monitor, evaluate, and adjust process parameters, eliminating reliance on operator experience and enabling comprehensive data-driven process analysis.

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

2Manufacturing precision

If comprehensive process analysis and automation are implemented, then process optimization and quality improvement are enabled, but system complexity increases

Engineering Contradiction:
Improveparticle foam component qualityVSAvoidcontrol system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the control system into distinct functional modules: sensors for data collection, a data processing unit for evaluation, and actuators for parameter adjustment. This modular segmentation manages system complexity by dividing the automated control function into manageable, specialized components while maintaining high manufacturing precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a data processing unit as an intermediary between the processing apparatus and the control system. This intermediary evaluates sensor data, compares it with target values, determines deviations, and generates adjustment commands, thereby simplifying the overall control architecture while enabling comprehensive process analysis and high-quality output.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If manual operator experience-based parameter setting is used, then implementation is simple, but process optimization is limited

Engineering Contradiction:
Improveprocess efficiencyVSAvoidsystem implementation simplicity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent implements a self-service control system where the processing apparatus automatically monitors its own parameters, evaluates performance against targets, and adjusts settings without external intervention. This self-regulating mechanism improves productivity through continuous optimization while the standardized automated routine maintains ease of implementation.

Inventive Principle:
Principle #25Self-service
