Solution Overview

Problem

Existing systems face challenges in accurately acquiring a target signal from time series signals output by devices like sensors and motors, as the accuracy of subsequent processing can be affected by the timing of signal acquisition.

Innovation Solution

A control apparatus and method that includes a first acquisition part, a recording part, and a determination part, where the determination part determines the timing for recording the first signal based on preset conditions, potentially using a second signal from a different device to ensure accurate acquisition of the target signal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If signal acquisition timing is not optimized, then processing accuracy may deteriorate, but system complexity increases when implementing timing determination mechanisms

Engineering Contradiction:
Improvesignal acquisition accuracyVSAvoidcontrol apparatus complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The determination part pre-establishes recording timing conditions and thresholds before signal acquisition begins. By determining the timing criteria in advance rather than calculating it in real-time during acquisition, the system achieves precise signal timing selection without adding complex real-time computation mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The signal recording system uses its own internal timing determination logic to automatically select optimal acquisition moments based on preset conditions. The determination part monitors the time series signal and autonomously decides when to trigger recording, eliminating the need for external timing control devices.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If multiple signals from different devices are integrated for timing determination, then signal acquisition accuracy improves, but device complexity and processing load increase

Engineering Contradiction:
Improvetarget signal acquisition accuracyVSAvoidmulti-device integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The determination part serves as an intermediary that receives time series signals from the first device and reference signals from the second device, then processes their relationship to determine optimal recording timing. This intermediary structure allows multiple devices to be integrated without requiring direct complex interactions between them.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The determination part is designed to handle multiple signal sources and various timing determination methods (threshold-based, event-based, or combination approaches) through a single unified mechanism. This multi-functional design allows the system to adapt to different signal types and timing criteria without requiring separate processing paths for each device.

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