Solution Overview

Problem

Measuring devices like oscilloscopes face challenges in handling large data volumes, where insignificant measurement results occupy the same storage space as significant ones, leading to either excessive storage needs or limited data retention duration, and existing data reduction methods compromise on analysis capabilities.

Innovation Solution

A measuring device with an interface for receiving signals, an acquisition memory for storing data segments, an analyzer for detailed analysis, and a memory controller to decide on data retention or discard based on analysis results, allowing for reduced storage while enabling thorough analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If all measurement data is stored to enable detailed analysis, then analysis capability is improved, but storage memory size increases significantly

Engineering Contradiction:
Improveanalysis capabilityVSAvoidstorage memory size
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent segments measurement data into individual data segments that can be independently analyzed and stored. The storage memory is divided into multiple storage locations, each capable of holding a complete data segment. This segmentation allows the system to store only selected segments that meet specific criteria rather than all segments, thereby reducing total storage requirements while maintaining detailed analysis capability for relevant data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by making different storage locations have different states - some are active (holding stored data segments) while others are inactive or overwritten. The system selectively stores data segments in specific storage locations based on analysis results, creating a non-uniform distribution of stored data that optimizes storage usage. This allows detailed analysis of important segments while discarding less important ones, resolving the contradiction between analysis capability and storage size.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If storage memory size is reduced to store only significant data, then storage efficiency is improved, but analysis capability deteriorates due to loss of valuable data

Engineering Contradiction:
Improvestorage memory sizeVSAvoidanalysis capability
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent performs preliminary analysis of each data segment before making the storage decision. The analysis unit evaluates each segment according to predetermined criteria (such as signal thresholds, pattern recognition, or other relevant parameters) before the segment is discarded or stored. This preliminary action ensures that only segments with significant characteristics are stored, preventing loss of valuable data while maintaining high storage efficiency. The detailed analysis capability is preserved because the decision to store or discard is based on thorough preliminary examination.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If basic analysis functions are used to reduce data storage, then storage requirements are reduced, but data reduction quality deteriorates due to sub-optimal analysis

Engineering Contradiction:
Improvestorage requirementsVSAvoiddata reduction quality
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent implements self-service by having the analysis unit automatically evaluate each data segment and generate analysis results that directly determine storage decisions. The system uses predetermined analysis criteria that are inherently optimized for the specific measurement context, eliminating the need for external or manual analysis. This self-service mechanism ensures high-quality data reduction because the analysis is performed consistently and thoroughly for each segment, achieving optimal data reduction quality while maintaining reduced storage requirements.

Inventive Principle:
Principle #25Self-service
