Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If portable electronic devices connect to external storage devices through data lines, then data exchange is achieved, but the devices cannot extend their memory directly and require connection to master devices

Engineering Contradiction:

Improvememory extension capabilityVSAvoidconnection structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile power device is designed to perform multiple functions: it can serve as a power source for electronic devices, provide external storage capacity, and act as either a master or slave device depending on the connected device's operating system. This multi-functionality eliminates the need for separate power banks and storage devices, directly resolving the contradiction between memory extension capability and connection complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device dynamically switches between master and slave roles based on the operating system of the connected electronic device. When connected to devices with non-target operating systems, it operates as a master device providing power and storage. When connected to devices with target operating systems, it operates as a slave device. This dynamic adaptability allows the device to extend memory capacity while maintaining simple connection structures across different device types

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If electronic devices are used frequently for diversified functions, then functionality is enhanced, but power runs out easily causing inconvenience

Engineering Contradiction:

Improvedevice functionalityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The mobile power device combines power supply functionality with storage capabilities in a single unit. The battery module provides power to electronic devices while the data storing module offers external storage, allowing users to extend device functionality without needing separate power banks and storage devices, thus addressing the power consumption issue while maintaining versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device automatically detects the operating system of connected devices and adjusts its master/slave role accordingly without requiring user intervention. This self-service capability ensures that power and storage functions are always available when needed, enhancing device functionality while managing power consumption efficiently through automated role switching

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If mobile power device switches between master and slave roles, then compatibility with different operating systems is achieved, but control logic becomes more complex

Engineering Contradiction:

Improveoperating system compatibilityVSAvoidcontrol logic

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The central processing unit automatically detects the operating system of connected electronic devices and dynamically switches the device's role between master and slave based on the detection results. This dynamic role switching achieves compatibility with different operating systems while the automated detection and switching logic minimizes the complexity burden on the user

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device incorporates a detection mechanism that provides feedback about the connected device's operating system to the central processing unit. Based on this feedback, the system automatically adjusts its master/slave role. This feedback-based control achieves broad operating system compatibility while keeping the control logic manageable through automated decision-making rather than requiring complex user configuration

Inventive Principle:

Principle #23Feedback
