Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple microphones are added to detect user inputs and improve voice recognition, then user input detection capability is improved, but device structure becomes complicated and manufacturing cost increases

Engineering Contradiction:
Improveuser input detection capabilityVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by enabling microphones to serve dual purposes: traditional voice recognition and physical input detection. By analyzing sound wave patterns from microphone signals, the system can detect tapping, knocking, or other physical gestures without requiring separate physical input buttons, thus resolving the contradiction between improved detection capability and device structure complexity

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

Solution Approach 2:

The patent replaces mechanical physical input buttons with an acoustic field-based detection system using microphones and sound wave analysis. This substitution eliminates the need for separate mechanical input components while maintaining or enhancing user input detection capability, thereby reducing device structural complexity and manufacturing costs

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If multiple microphones are added to detect user inputs and improve voice recognition, then user input detection capability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveuser input detection capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent makes microphones perform multiple functions (voice recognition and physical input detection), which justifies their inclusion without requiring additional separate components. This multi-functionality approach reduces overall manufacturing cost by eliminating the need for separate physical input buttons while maintaining enhanced user input detection capability

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

Solution Approach 2:

By replacing mechanical physical input buttons with microphone-based acoustic detection, the patent reduces the bill of materials and assembly complexity. The same microphone hardware serves dual purposes, reducing manufacturing costs while improving or maintaining user input detection capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If multiple microphones are added to detect user inputs, then user input detection capability is improved, but design flexibility is limited

Engineering Contradiction:
Improveuser input detection capabilityVSAvoiddesign flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent replaces fixed mechanical physical input buttons with flexible microphone-based acoustic detection. This substitution provides greater design flexibility as microphones can be positioned more freely in the device structure without requiring dedicated button spaces, allowing for more varied form factors and device layouts while maintaining enhanced user input detection capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
