Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional microphone is used to capture voice, then voice signals can be detected, but ambient noise cannot be effectively blocked

Engineering Contradiction:

Improveambient noiseVSAvoidvoice detection accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent replaces the traditional acoustic microphone with a piezoelectric-based vibration detection system. The piezoelectric element directly contacts the user's body to detect mechanical vibrations from voice, substituting acoustic wave detection with mechanical vibration detection, thereby fundamentally blocking ambient noise

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a piezoelectric element as an intermediary between the user's voice and the detection system. This intermediary converts mechanical vibrations from the user's body into electrical signals, enabling voice detection while excluding ambient noise that does not contact the user's body

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If human translators are used for language translation, then translation services can be provided, but it is difficult to arrange translators for all languages and they cannot provide services at desired times

Engineering Contradiction:

Improvelanguage coverageVSAvoidtranslation service availability

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent enables users to perform translation themselves through portable electronic devices with built-in translation functionality. The system allows users to independently translate languages without requiring external human translators, making translation services universally accessible

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent creates a universal translation system that can handle multiple languages through a single electronic device. The translation device incorporates diverse language databases and processing capabilities, allowing one device to serve multiple translation needs across different language pairs

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If translators are accompanied at all times to provide translation services, then translation needs can be met, but it is unreasonable that one or two translators cannot provide satisfactory services to large numbers of visitors

Engineering Contradiction:

Improvetranslation service qualityVSAvoidtranslation system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces human translators with electronic translation devices that automatically process language translation. This substitution eliminates the need for human translators to be physically present with users, providing scalable translation services without increasing system complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses electronic copies of language data and translation algorithms stored in portable devices. Instead of requiring physical human translators, the system uses digital copies of linguistic knowledge that can be replicated and distributed across multiple devices, serving numerous users simultaneously

Inventive Principle:

Principle #26Copying
