Solution Overview

Problem

The complexity of operating injection molding machines has increased due to the variety of machines and manufacturing options, making it difficult for operators to navigate and find relevant parameters across numerous screens and program pages, leading to inefficient operation.

Innovation Solution

A hierarchical system architecture for the operating program with a main level offering system-specific and task-specific menus, allowing selection between plant areas and task areas, reducing the number of levels and displaying only process-relevant program pages, along with user role-based access rights and configuration parameters to simplify navigation and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the operating program provides full access to all machine functions and parameters across multiple screens, then the system offers high adaptability and completeness, but the operating complexity and difficulty of finding relevant parameters increase significantly

Engineering Contradiction:
Improveaccess to machine functionsVSAvoidnavigation difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The operating program is segmented into multiple hierarchical levels (upper level and sublevels) with distinct functional areas. Each level displays only a subset of parameters and functions relevant to that specific level, breaking down the overwhelming full parameter set into manageable, organized sections that reduce navigation complexity while maintaining comprehensive access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the operating program structure, adding levels of organization above the traditional single-level screen display. This dimensional addition allows parameters to be accessed through multiple pathways (direct access at upper level or detailed access at sublevels), reducing the search space at each level while preserving complete system accessibility.

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

2Loss of information

If the operating program displays all available parameters and program pages, then complete information is provided, but the time required to find and navigate to relevant parameters increases

Engineering Contradiction:
Improveparameter visibilityVSAvoidnavigation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The upper level of the hierarchical system performs preliminary organization of all parameters and functions into logical groups and areas before the operator needs to access them. This pre-organization reduces the time required to locate specific parameters, as the system has already structured the information in a navigable hierarchy rather than presenting it as an unorganized complete set.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By segmenting the complete parameter set into hierarchical levels and functional areas, the patent reduces the information overload at any single display level. Operators can quickly navigate to relevant segments without being presented with all parameters simultaneously, significantly reducing search and navigation time while maintaining access to complete information through the hierarchical structure.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the operating program provides access to the full range of machine functions, then system versatility is maximized, but the number of screens and parameters increases complexity

Engineering Contradiction:
Improvefunctionality rangeVSAvoidoperating program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent adds a hierarchical dimension to organize the full range of machine functions, structuring them across multiple levels rather than presenting them as a flat complex interface. This dimensional reorganization maintains complete system functionality while reducing perceived complexity by providing structured access pathways and logical groupings at each level.

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

Solution Approach 2:

The operating program is segmented into hierarchical levels where each level presents a simplified view of the complete system functionality. This segmentation allows the full range of machine functions to be accessed while reducing operating program complexity at any given display level, as parameters are divided into logical groups rather than presented as an undifferentiated mass.

Inventive Principle:
Principle #1Segmentation

AI summary

The unit has a touch-sensitive screen for displaying operating program, and a controlling or regulating unit for transmitting operating signals to injection molding machine elements, where operating program (B) is stored in the regulating unit. An operating key is operated such that the regulating unit releases action of the elements. The operating program has hierarchical system architecture with upper system-specific plane (M1) and upper task-specific plane (M2), where program sides (P) assigned to selected system area or selected task area are displayed in selected sublayer (U). An independent claim is also included for a method for operating an operating unit.
