Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is manually copied to portable computing device before travel, then data access is enabled, but user convenience deteriorates and time is lost

Engineering Contradiction:

Improvedata access availabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by automatically identifying and copying required data to portable devices before the user travels, eliminating the need for manual data preparation. The automated system proactively prepares data in advance based on user profiles and travel information, ensuring data availability without user intervention.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically selecting, copying, and managing data without requiring user action. The automated data identification and transfer process serves itself by using user profiles, travel itineraries, and database information to independently determine what data to prepare and where to store it.

Inventive Principle:

Principle #25Self-service

2Reliability

If all required data is copied to portable computing device, then data access completeness is improved, but device storage capacity is exceeded

Engineering Contradiction:

Improvedata access completenessVSAvoidstorage capacity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system applies local quality by distributing data storage across multiple locations rather than concentrating all data on the portable device. Data is stored locally on the portable device when needed, while other data remains in remote databases or on external storage devices, allowing complete data access without overwhelming device storage capacity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system segments data storage by dividing data into portions stored on the portable computing device and portions stored in remote databases or external storage. This segmentation allows the user to access complete data sets while only the essential portion occupies limited portable device storage.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If data is accessed through remote networking technology, then data portability is maintained, but data transmission speed deteriorates

Engineering Contradiction:

Improvedata portabilityVSAvoiddata transmission rate

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The system performs preliminary actions by copying required data to the portable computing device before the user travels to locations with limited or slow network connectivity. This advance preparation ensures fast local data access when remote networking would be slow or unavailable.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The portable computing device acts as an intermediary between remote databases and the user. It stores local copies of data, serving as a mediator that provides fast access without requiring continuous connection to remote networks, thus maintaining data portability while eliminating transmission speed limitations.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Quantity of substance

If external storage device is used to transport data, then storage capacity is sufficient, but physical connection requirements increase complexity

Engineering Contradiction:

Improvestorage capacityVSAvoidconnection complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system merges the functions of the portable computing device and external storage device by automatically copying required data to the portable device's internal storage. This integration eliminates the need for separate external storage devices and physical connection operations, reducing complexity while maintaining sufficient storage capacity.

Inventive Principle:

Principle #5Merging (Combining)
