Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single audiologic test apparatus is used to perform multiple different audiologic tests (e.g., screening and diagnostic acoustic reflex tests), then device versatility is improved, but device complexity increases due to the need for multiple probe connectors and pump module configurations
Solution Approach 1:
The audiologic test apparatus is designed with a universal pump module that can perform multiple different audiologic tests (screening acoustic reflex, diagnostic acoustic reflex, tympanometric, and otoacoustic emission tests) by switching between different probe connectors. The pump module serves as a multi-functional component that adapts to various test requirements through electronic control, eliminating the need for separate dedicated devices for each test type.
Solution Approach 2:
The pump module implements dynamic switching between different operating modes corresponding to different audiologic tests. The system can dynamically reconfigure its fluid circuitry by activating different pump connectors (first pump connector for screening tests, second pump connector for diagnostic tests) based on the selected test type, allowing the apparatus to adapt its functionality in real-time without physical reconfiguration.
2Ease of operation
If multiple separate apparatuses are used for different audiologic tests, then ease of operation for each specific test is improved, but loss of time due to device switching and configuration increases
Solution Approach 1:
The invention merges multiple separate audiologic test apparatuses into a single integrated device. By combining the capabilities of screening acoustic reflex testers, diagnostic acoustic reflex testers, tympanometers, and otoacoustic emission testers into one apparatus with a universal pump module and multiple probe connectors, the system eliminates the need to physically switch between separate devices, thereby reducing time loss while maintaining ease of operation for each specific test type.
Solution Approach 2:
The apparatus is pre-configured with multiple probe connectors and fluid circuitry pathways ready for different test types. When a specific audiologic test is selected, the corresponding pump connector and probe configuration are automatically activated without requiring manual reconfiguration or setup time, as all necessary components are prepared in advance within the single apparatus.
3Adaptability or versatility
If a configurable probe system is used to accommodate different audiologic tests, then adaptability is improved, but loss of time due to configuration requirements increases
Solution Approach 1:
The pump module incorporates automatic self-service functionality that detects which probe is connected and automatically configures the appropriate fluid circuitry and operating parameters. The system performs self-diagnosis to identify the connected probe type and automatically activates the corresponding pump connector and test protocol, eliminating the need for manual configuration by the operator and reducing configuration time to nearly zero.
