Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If connection devices are equipped with fixed configurations to meet specific user requirements, then the device can provide desired functionalities, but the development, production and storage expenses increase significantly

Engineering Contradiction:
Improvefunctional configurationVSAvoidproduction expense
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connection device is divided into modular components that can be independently manufactured and assembled. Each module can be produced separately at lower cost, then combined to create different functional configurations, reducing overall production expenses while maintaining versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device employs universal base units and standardized interfaces that can support multiple functional modules. A single base structure can accommodate various modules (charging modules, payment modules, display modules, etc.), eliminating the need to manufacture separate fixed-configured devices for each function combination.

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

2Reliability

If connection devices are firmly configured for specific charging technologies, then the device can provide stable performance, but convertability and ability to adapt to new requirements are limited

Engineering Contradiction:
Improvecharging performanceVSAvoidconvertability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connection device transitions from a static fixed configuration to a dynamic modular structure. Modules can be added, removed, or replaced based on evolving charging technologies and user needs, while maintaining reliable connections through standardized interfaces and secure mounting mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Functional modules are designed to be nested within or attached to a standardized base structure. This nesting approach allows the core reliable connection functionality to remain stable while permitting interchangeable modules to be inserted or removed, enabling convertability without compromising structural integrity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If different functionalities are integrated into connection devices to meet varying user needs, then the device can serve diverse requirements, but the device complexity increases

Engineering Contradiction:
Improvefunctional diversityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Complex functionalities are segmented into separate modular units, each performing a specific function. This segmentation reduces the complexity of individual modules while the standardized interface simplifies the overall system integration, making the device easier to manufacture and maintain despite offering diverse functionalities.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If modules are inserted into the receiving profile to achieve flexible configuration, then the connection device can be easily expanded or altered, but the mechanical design becomes more complex

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidmechanical design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A universal receiving profile design with standardized mounting interfaces allows different module types to be attached using the same mechanical structure. This universality simplifies the mechanical design by eliminating the need for custom mounting mechanisms for each module type, reducing overall complexity while maintaining configuration flexibility.

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