Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ultrasonic measuring system uses external vibration source, high-voltage excitation module, and complex circuitry, then measurement precision is improved, but device complexity increases and system size becomes large
Solution Approach 1:
The mobile device serves multiple functions: it generates vibration signals through its speaker, amplifies them through its amplifier, and processes ultrasound signals through its processor. This multi-functionality replaces multiple dedicated components (vibration source, excitation module, signal processing circuits) with a single universal device, reducing system complexity while maintaining measurement capability
Solution Approach 2:
The patent combines the vibration generation function and ultrasound measurement function into an integrated system where the mobile device handles both signal generation and signal processing. The vibration conducting seat merges the mechanical coupling function with the mounting structure, creating a compact integrated system that eliminates the need for separate external vibration sources and complex circuitry
2Measurement precision
If conventional ultrasonic measuring system uses multiple circuits and modules, then measurement capability is improved, but system size increases and cost increases
Solution Approach 1:
The mobile device's processor performs multiple tasks: controlling the speaker for vibration generation, amplifying signals through the amplifier, generating ultrasound signals via the transducer, and processing echo signals for elasticity analysis. This consolidation of multiple functions into one device dramatically reduces system volume while preserving full measurement capability
Solution Approach 2:
The mobile device uses its own built-in components (speaker, amplifier, processor) to generate and process signals without requiring external dedicated hardware. The system leverages the mobile device's existing capabilities to serve the measurement function, eliminating the need for additional external equipment and reducing overall system size
3Force
If conventional ultrasonic measuring system uses high-voltage excitation module and additional circuits, then vibration generation capability is improved, but device complexity and cost increase
Solution Approach 1:
The mobile device's speaker and amplifier combination serves as both the vibration source and signal amplifier. The speaker, designed for audio output, generates sufficient vibration force when driven by the mobile device's amplifier, replacing the need for dedicated high-voltage excitation modules while using readily available consumer electronics components
Solution Approach 2:
The system replaces expensive, complex high-voltage excitation modules with common, inexpensive mobile device components (speaker, amplifier) that are readily available in consumer electronics. This substitution uses cheaper, more accessible components to achieve the same vibration generation function
