Solution Overview

Problem

Existing control systems for flash lighting devices and similar applications face challenges in signal processing due to noise interference, affecting accuracy and reliability.

Innovation Solution

A control device system that uses a control signal with multiple addresses (main and collation signal addresses) to transmit and receive signals, allowing for noise-resistant processing, and employs a method where specific addresses are turned ON or OFF consecutively to enhance detection accuracy and enable long-distance signal transmission using wired signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If wired signals are used for control transmission, then long-distance transmission is enabled, but noise interference affects signal processing accuracy

Engineering Contradiction:
Improvetransmission distanceVSAvoidsignal processing accuracy
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The control signal is divided into multiple segments with different addresses (main signal address and collation signal address). Each segment carries partial information, and the complete control command is reconstructed by combining segments with matching addresses. This segmentation allows the system to transmit control signals over long wired distances while maintaining accuracy by verifying address matches to filter out noise-corrupted segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback through collation signal addresses that are associated with main signal addresses. The control signal includes both a main address and a collation address, allowing the receiving end to verify signal integrity by checking address consistency. This feedback mechanism enables noise-resistant processing by identifying and discarding corrupted signals while maintaining reliable long-distance transmission.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If multiple address signals are used for noise-resistant processing, then detection accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidsignal processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control signal is segmented into multiple addressable components (main signal address and collation signal address). Each segment can be independently processed and verified, improving detection accuracy by allowing selective validation of signal portions. The segmentation approach manages complexity by organizing signal processing into discrete, manageable address-matching operations rather than complex continuous verification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses collation signal addresses that are copies or associations of main signal addresses. This copying mechanism allows verification of signal integrity through address matching without requiring complex verification logic. The receiving device simply compares the collation address with the main address to validate the signal, achieving high detection accuracy with minimal processing complexity.

Inventive Principle:
Principle #26Copying
