Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional earphone testing device is used, then the device structure is simple, but the testing precision and stability are insufficient
Solution Approach 1:
The testing device is divided into distinct functional modules: a fixation base for securing the earphone, a standard microphone assembly for acoustic measurement, and a sealer component for sealing. This segmentation allows each module to be optimized independently while maintaining overall system precision without excessive complexity.
Solution Approach 2:
The sealer acts as an intermediary component between the fixation base and the earphone/standard microphone, creating a sealed interface that prevents sound leakage. This intermediary element ensures accurate acoustic measurement by blocking unwanted sound paths while maintaining a relatively simple overall device structure.
2Reliability
If the fixation base is unstable, then the device complexity is reduced, but the testing result stability deteriorates
Solution Approach 1:
The fixation base incorporates pre-designed supporting elements and a sealer structure that are prepared in advance to ensure stable positioning of the earphone and standard microphone. This preliminary configuration of fixation components ensures consistent and stable testing results without requiring complex real-time adjustment mechanisms.
Solution Approach 2:
The sealer component utilizes a flexible sealing structure that can adapt to the contours of the earphone and standard microphone while maintaining a tight seal. This flexible sealing mechanism provides stable acoustic isolation without adding significant structural complexity to the fixation base.
3Measurement precision
If sound leakage occurs, then the device structure is simpler, but the measurement precision deteriorates
Solution Approach 1:
The sealer serves as an intermediary sealing element positioned between the fixation base and the acoustic components (earphone and standard microphone). This sealing intermediary prevents sound leakage by blocking unwanted acoustic paths, ensuring precise acoustic measurement while adding minimal structural complexity.
Solution Approach 2:
The sealing structure employs a flexible sealer that can conform to the surfaces of the earphone and standard microphone, creating an effective acoustic seal. This flexible sealing approach achieves precise acoustic isolation without requiring complex rigid sealing mechanisms, maintaining measurement precision while keeping the device structure relatively simple.
