Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual video recording and playback method is used to check flicker frequency, then the device complexity is reduced, but the checking efficiency and accuracy deteriorate significantly
Solution Approach 1:
The patent replaces the manual mechanical video recording and playback method with an automated electronic detection system. The processing unit automatically acquires light emitting intensity data from the lighting effect file, calculates flicker frequency through computational algorithms, and compares against predetermined specifications without requiring physical video recording equipment or manual observation.
Solution Approach 2:
The lighting effect editing device performs self-detection of flicker frequency compliance. The processing unit automatically extracts lighting effect data, computes flicker frequency, and generates compliance determination results without requiring external manual checking. The system serves its own quality control needs through integrated automated detection capabilities.
2Measurement precision
If manual eye-checking method is used, then the measurement precision requirement is reduced, but the measurement accuracy of flicker frequency location deteriorates
Solution Approach 1:
The patent introduces a processing unit as an intermediary between the lighting effect file and the compliance determination. This processing unit automatically extracts intensity data, calculates flicker frequency, identifies non-compliant segments, and provides precise location information. The intermediary system bridges the gap between raw data and compliance verification, delivering both accuracy and location information.
Solution Approach 2:
The system implements feedback by automatically comparing calculated flicker frequency against predetermined specifications and generating compliance determination results. The processing unit provides feedback information about which segments of the lighting effect file comply or violate specifications, enabling precise identification of non-compliant locations through automated comparison and analysis.
3Adaptability or versatility
If multiple lighting effect files are concatenated into continuous lighting effect, then the versatility is improved, but the time required for manual checks increases
Solution Approach 1:
The patent implements continuous automated processing of lighting effect files. The processing unit continuously acquires intensity data, calculates flicker frequency, and determines compliance for all segments of concatenated lighting effect files without interruption. This continuous automated action eliminates the need for manual segmentation and checking of multiple files, maintaining versatility while reducing time requirements.
Solution Approach 2:
The system performs preliminary automated analysis of lighting effect files before final compliance determination. The processing unit pre-processes the data by extracting intensity information, calculating flicker frequency parameters, and identifying potential non-compliant segments in advance. This preliminary action enables efficient handling of multiple concatenated files without requiring time-consuming manual verification.

AI summary
When a developer edits a lighting effect file played by single one or multiple light emitting units of a sounding and lighting device, a lighting effect editing device and method provided by the present disclosure enable the developer to simultaneously determine whether playing single one lighting effect file once, playing single one lighting effect file repeatedly, playing a concatenation of multiple lighting effect files once, playing a concatenation of multiple lighting effect files repeatedly, playing a mixture of multiple lighting effect files once, playing multiple lighting effect files simultaneously once, playing multiple lighting effect files simultaneously repeatedly, playing multiple concatenation lighting effect files simultaneously once or playing multiple concatenation lighting effect files simultaneously repeatedly generates a flicker frequency not meeting a predetermined specification. In addition, when there exists the flicker frequency not meeting the predetermined specification, the developer may be notified of a location of a corresponding sampling time point.
