Solution Overview

Problem

Existing measuring devices require significant user expertise and manual intervention, leading to inefficiencies, especially when no user is present, as they need to be readjusted between measurements and can be time-consuming to adapt to unforeseen events or repeated measurements.

Innovation Solution

A method and device where a control device autonomously selects samples, establishes conditions, creates measured values, and updates a database, allowing for automated operation, reduced user burden, and increased efficiency by selecting samples based on previous conditions or measured values, and repeating measurements outside plausible ranges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If measuring devices are used by multiple users or for consecutive measurements, then the device can serve more applications, but it requires manual readjustment between measurements which reduces efficiency

Engineering Contradiction:
Improvedevice utilization for multiple measurementsVSAvoidmeasurement efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The control device autonomously selects samples and adjusts measurement parameters without requiring manual intervention. The system automatically determines which samples to examine next based on stored measurement conditions and criteria, enabling the measuring device to serve itself for consecutive measurements while maintaining adaptability to different measurement requirements

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Measurement conditions and selection criteria are established in advance and stored in the control device. This preliminary setup allows the system to automatically proceed with subsequent measurements without requiring users to reconfigure settings, thereby maintaining versatility while improving productivity through automated sequential processing

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If users manually control the measuring device, then they can adapt to unforeseen events, but it requires significant user expertise and time which reduces efficiency

Engineering Contradiction:
Improveability to handle unforeseen eventsVSAvoidtime for measurement preparation and execution
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The control device automatically monitors measurement results and compares them against stored criteria and plausible ranges. When measurement values fall outside expected parameters, the system autonomously identifies and corrects potential errors or repeats measurements, providing adaptive response to unforeseen events without requiring user intervention or extensive expertise

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system independently handles unexpected measurement outcomes by automatically detecting errors, determining appropriate corrective actions, and executing remedial measurements. This self-correcting capability reduces both the time required to handle unforeseen events and the expertise level needed to operate the device

Inventive Principle:
Principle #25Self-service

3Productivity

If the measuring device operates autonomously, then efficiency increases and user burden decreases, but the device complexity increases

Engineering Contradiction:
Improvemeasuring device efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control device is designed to perform multiple functions: selecting samples, establishing measurement conditions, executing measurements, monitoring results, and automatically correcting errors. By consolidating these diverse functions into a single multi-functional control system, the patent achieves high productivity while managing complexity through functional integration rather than proliferation of separate components

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Measurement precision

If measurements are repeated for quality control, then measurement accuracy improves, but additional time is required which reduces productivity

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidmeasurement throughput
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The control device autonomously monitors measurement results and automatically determines when repetitions are necessary based on pre-established criteria. By intelligently selecting only those measurements that require repetition rather than universally repeating all measurements, the system maintains high measurement accuracy while minimizing the time penalty, thereby preserving productivity

Inventive Principle:
Principle #25Self-service
