Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the measuring device records and analyzes the entire measuring signal to determine suitable trigger functions, then the user assistance is improved, but the hardware complexity and computational complexity increase significantly

Engineering Contradiction:
Improveuser assistance in trigger selectionVSAvoidhardware complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts only the essential trigger-relevant features from the measuring signal rather than analyzing the entire signal. The triggering unit identifies specific trigger conditions (edges, levels, patterns) and extracts only those portions of the signal that are relevant for trigger determination, discarding unnecessary data. This extraction approach provides user assistance while avoiding the hardware and computational complexity of full-signal analysis.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If diverse trigger functions and parameter settings are provided, then the adaptability is improved, but the ease of operation deteriorates for novice users

Engineering Contradiction:
Improvetrigger function varietyVSAvoiduser operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The measuring device performs self-service by automatically analyzing the measuring signal and autonomously selecting appropriate trigger functions and parameters. The triggering unit monitors the signal characteristics and automatically configures optimal trigger settings without requiring the user to navigate through diverse trigger options. This self-service mechanism maintains adaptability to different signal types while eliminating the complexity burden on novice users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device performs preliminary analysis of the measuring signal to pre-determine suitable trigger functions before the user needs to make selections. By提前 analyzing signal characteristics and pre-configuring appropriate trigger parameters, the system prepares optimal settings in advance, allowing users to simply accept recommended configurations rather than struggling with diverse trigger options.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If the entire measuring signal is recorded for analysis, then the measurement accuracy is improved, but the data storage requirements and processing time increase

Engineering Contradiction:
Improvetrigger determination accuracyVSAvoiddata storage requirements
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only trigger-relevant data points from the measuring signal for storage and analysis. Instead of recording the entire signal, the triggering unit identifies and stores only the specific conditions and parameters necessary for trigger determination (such as edge transitions, level crossings, and pattern occurrences). This extraction maintains measurement precision for trigger analysis while dramatically reducing data storage requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If comprehensive signal analysis is performed to assist users, then the productivity is improved, but the computational complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent segments the signal analysis process into distinct, simplified stages: signal acquisition, trigger condition detection, parameter extraction, and trigger function selection. Each segment performs a specific function with optimized computational requirements. The triggering unit divides the comprehensive analysis into modular tasks that can be executed efficiently, maintaining high measurement productivity while avoiding the computational burden of undifferentiated full-signal analysis.

Inventive Principle:
Principle #1Segmentation
