Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional multi-pin connectors are used for wired connections, then reliable power and signal transmission is achieved, but the device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnector complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical contact-based signal transmission system with a wireless communication system. The connector now only needs to provide power transmission through simple electrical contacts, while all data and control signals are transmitted wirelessly via integrated antennas and communication modules, eliminating the need for complex multi-pin signal connectors

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

Solution Approach 2:

The patent extracts the signal transmission function from the mechanical connector structure and separates it into an independent wireless communication subsystem. This allows the connector to focus solely on power transmission while signal communication occurs through wireless means, significantly simplifying the physical connector design

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If multiple contact pins are provided for power and signal transmission, then comprehensive functionality is achieved, but the number of poles increases to a maximum of two or zero with inductive transmission

Engineering Contradiction:
Improvetransmission functionalityVSAvoidnumber of contacts
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent replaces mechanical contact-based signal transmission with wireless electromagnetic field-based transmission. Integrated antennas and communication modules enable all data exchange to occur wirelessly, reducing the connector to only the essential power transmission contacts or even eliminating physical contacts entirely through inductive power transfer

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

Solution Approach 2:

The wireless communication subsystem serves multiple functions simultaneously: data transmission, control signaling, and potentially power transfer through the same electromagnetic field interface, eliminating the need for separate dedicated contacts for each function

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

3Reliability

If conventional connectors are designed to meet safety and explosion protection requirements, then high safety standards are met, but manufacturing becomes time-consuming and costly

Engineering Contradiction:
Improvesafety standard complianceVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the complex mechanical connector structure with a simplified design that uses wireless communication for all signal transmission. This reduction in mechanical complexity and number of exposed contacts significantly eases manufacturing while maintaining safety standards, as there are fewer components that require precision assembly and testing

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

Solution Approach 2:

The simplified connector design with fewer critical components allows for more cost-effective manufacturing processes and potentially replaceable modular units, reducing overall system cost while maintaining required safety performance

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If wired connections with multiple pins are used, then stable power and data transmission is achieved, but maintenance requirements increase and service life decreases

Engineering Contradiction:
Improvetransmission stabilityVSAvoidservice life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent eliminates mechanical wear by replacing contact-based signal transmission with wireless electromagnetic communication. The only physical contact required is for power transmission, and even this can be eliminated through inductive coupling, thereby removing the primary source of mechanical degradation and extending connector service life

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