Solution Overview

Problem

Existing thermoforming apparatuses face challenges in simplifying the setup phase to reduce errors and improving anomaly detection and analysis, making it difficult for operators to quickly and reliably identify issues and their causes within the thermoforming cycle.

Innovation Solution

A touchscreen-based control method that displays icon segments representing various operations of the thermoforming cycle, allowing operators to adjust durations and settings by touching the screen, with features for real-time monitoring and anomaly detection, enabling easy identification of issues and their origins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional control interfaces are used for setting thermoforming cycles, then the control device is simple and economical, but the setup phase is complex and error-prone

Engineering Contradiction:
Improvesetup phase simplicityVSAvoidcontrol interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses graphical icon segments that visually copy and represent the actual thermoforming operations and their temporal sequence. Instead of complex numerical parameters, the interface displays simplified visual representations (icons) of heating, forming, cooling operations arranged along a timeline, making setup intuitive and error-resistant while maintaining economical device complexity

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transforms the one-dimensional temporal sequence of operations into a two-dimensional visual display with icon segments arranged along a timeline. This dimensional transformation allows operators to grasp the entire cycle structure at a glance, adjust parameters by dragging icons along the timeline, and immediately see the impact on cycle duration and operation sequencing

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If detailed monitoring of all thermoforming operations is implemented, then anomaly detection capability is improved, but the control interface becomes more complex

Engineering Contradiction:
Improveanomaly detection capabilityVSAvoidcontrol interface complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the thermoforming cycle into distinct operational segments represented by separate icon segments (heating, forming, cooling phases). Each icon segment can be individually monitored and analyzed for anomalies. This segmentation allows detailed monitoring of specific operations without overwhelming the interface, as each segment is displayed and controlled independently along the timeline

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs color coding to visually indicate the status of different operations and detect anomalies. Different colors represent different operational states or anomaly conditions, enabling rapid visual detection of issues without requiring complex data analysis or additional interface elements

Inventive Principle:
Principle #32Color changes
