Solution Overview

Problem

Existing software-based planning methods for dimensional measurement are cumbersome and require significant user expertise due to the overwhelming number of simultaneously displayed test features, making it difficult for users to select the relevant features for the measurement plan.

Innovation Solution

A method and device that dynamically reduce the display of test features based on the user's current view, showing only those that are readily visible and relevant, allowing users to select features through intuitive interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all measurable test features are displayed simultaneously on the display, then the user has complete information available for selection, but the user interface becomes overwhelming and difficult to navigate

Engineering Contradiction:
Improvecompleteness of test feature informationVSAvoidease of test feature selection
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the complete set of measurable test features into multiple subsets based on different classification criteria (e.g., geometric element type, measurement category). Each subset is displayed separately on the user interface, allowing users to navigate through organized groups rather than facing all features simultaneously. This segmentation maintains information completeness while improving navigability and selection ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an additional organizational dimension by categorizing test features according to the geometric element to which they belong. Instead of displaying all features in a single flat list, features are structured hierarchically or spatially according to their associated geometric elements, adding a dimensional layer to the interface that facilitates systematic browsing and selection.

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

2Manufacturing precision

If comprehensive measurement parameters are planned manually, then measurement accuracy can be ensured, but the time required to create measurement plans increases significantly

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidtime to create measurement plan
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by automatically generating draft measurement plans based on imported geometric element data before user review. The system pre-configures measurement sequences, selects appropriate test features, and sets initial parameters based on the geometric elements detected in the imported data, thereby reducing the manual planning time while maintaining measurement accuracy through subsequent user verification.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables self-service functionality where the measurement planning system automatically performs tasks that would otherwise require manual expert input. The system autonomously imports geometric element data, identifies measurable features, and generates measurement sequences without requiring extensive manual configuration, thereby reducing both time consumption and the need for specialized expertise while preserving measurement quality.

Inventive Principle:
Principle #25Self-service

AI summary

A method for software-based planning of a dimensional measurement of a measurement object includes receiving an input command for selecting at least one measurement element of the measurement object that is to be measured during the measurement. The method includes determining a selection of measurable test features of the at least one selected measurement element. Each of the test features includes a dimensionally measurable measurand of the at least one selected measurement element. The method includes determining a reduced subset of the selection of measurable test features depending on a view currently chosen on a display. The method includes visualizing the test features contained in the reduced subset by generating a graphical representation of each of the test features contained in the reduced subset on the display.
