Innovation Solution

A keyboard with a touch screen and rotatable dials that provides an intuitive user interface, allowing for touch inputs, adaptive layout adjustments, and wireless communication with audiological test instruments to simplify the operation of various tests and improve user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional standalone audiometers use multiple physical pressure keys and dials to enable comprehensive hearing test functions, then the device can perform various audiological tests, but the user interface becomes complex and the device size increases

Engineering Contradiction:
Improvehearing test functionsVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by integrating multiple control functions into a single touchscreen interface that can display different layouts for various hearing test types (pure tone, speech audiometry, impedance). The touchscreen replaces multiple dedicated physical keys and dials, allowing one interface element to perform multiple functions depending on the selected test mode, thereby reducing overall device complexity while maintaining comprehensive test capabilities

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamics through an adaptive touchscreen interface that dynamically changes its layout and configuration based on the selected hearing test type. The interface transitions between different operational modes (pure tone with frequency/intensity controls, speech audiometry with different parameters), allowing the same physical interface to adapt its functionality rather than requiring static dedicated controls for each test type

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If PC-based audiometers use standard keyboards for control, then the device can be operated with familiar input methods, but the keyboard requires many keys for non-audiological functions that increase complexity and reduce usability

Engineering Contradiction:
Improvefamiliar input methodVSAvoidkeyboard key count
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts only the essential audiological control functions from a standard keyboard layout, creating a customized touchscreen interface that includes only the keys and controls necessary for hearing tests (frequency adjustment, intensity control, test type selection). This extraction removes unnecessary non-audiological keys while preserving the familiar QWERTY-based navigation patterns, reducing complexity while maintaining ease of operation for the specific medical application

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If audiometers are designed for international use with multiple country-specific designs and labelling, then the device can accommodate different regional requirements, but the device complexity and variety of designs increase

Engineering Contradiction:
Improveinternational compatibilityVSAvoiddesign variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a single touchscreen interface design that can adapt to multiple international requirements through software configuration rather than hardware redesign. The touchscreen can display different languages, symbols, and layout configurations for different countries and regions, allowing one physical device design to serve multiple international markets without requiring separate designs for each country

Inventive Principle:
Principle #6Universality (Multi-functionality)
