Engineering Contradiction Analysis
1Measurement precision
If specialized vibration analysis hardware and software are used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms vibration signals into audio data format. This mediator approach allows standard audio processing hardware and software to analyze vibration data indirectly, eliminating the need for specialized vibration analysis equipment while maintaining measurement capability.
Solution Approach 2:
The patent creates a digital copy of the vibration signal in the form of audio data. By converting the vibration signal into audio data format, the system can use existing audio processing tools and software to analyze the vibration characteristics, avoiding the need for expensive specialized hardware.
2Measurement precision
If specialized vibration analysis hardware is used, then measurement precision is improved, but portability deteriorates
Solution Approach 1:
The patent converts vibration signals into audio data format, creating a portable digital copy that can be processed by standard audio equipment. This allows the analysis system to be portable and move with the machinery being analyzed, rather than requiring fixed specialized hardware at the machine location.
Solution Approach 2:
The patent makes the analysis system universal by using standard audio processing hardware and software that can analyze any vibration signal converted to audio data. This multi-functional approach allows the same portable device to analyze different types of machinery vibrations without requiring machine-specific specialized equipment.
3Measurement precision
If specialized vibration analysis software is used, then measurement precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent uses audio data as an intermediary format that serves as a universal language between vibration sensors and analysis software. This mediator approach allows different vibration analysis software packages to process the same audio data format, improving compatibility and adaptability across multiple software systems.
Solution Approach 2:
The patent creates a universal interface by converting vibration signals into audio data that can be processed by various different software applications. This allows the system to adapt to different software environments and analysis tools without requiring proprietary specialized software for each application.
