Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data synchronization is performed frequently to ensure data access quality, then data access reliability is improved, but network energy consumption increases

Engineering Contradiction:

Improvedata access qualityVSAvoidnetwork energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the synchronization frequency adaptive rather than fixed. The system dynamically adjusts polling intervals based on real-time network quality assessment and device movement detection. When network quality is poor or the device is moving, synchronization frequency is reduced; when network quality is good and the device is stationary, frequency increases, thus optimizing both data access quality and energy consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of synchronization frequency based on assessed conditions. It monitors network quality metrics and device movement status, then adjusts the polling interval parameter accordingly. This parameter adaptation allows the system to maintain data access quality when conditions permit while reducing energy consumption when conditions deteriorate.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If data synchronization frequency is increased to maintain data access quality during movement, then data access reliability is improved, but data exchange time increases

Engineering Contradiction:

Improvedata access qualityVSAvoiddata exchange time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary assessment of network quality and device movement status before initiating data synchronization. By predicting future network conditions and movement patterns, it prepares appropriate synchronization strategies in advance, avoiding unnecessary synchronization attempts that would waste time and resources.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The synchronization frequency is dynamically adjusted based on real-time conditions. When the device is detected to be moving or network quality is poor, the system reduces synchronization frequency to minimize data exchange time. When conditions improve, frequency increases to maintain data access quality, thus balancing both requirements.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If network quality assessment is performed continuously to adapt synchronization, then adaptability is improved, but processing energy consumption increases

Engineering Contradiction:

Improvesynchronization adaptabilityVSAvoidprocessing energy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs network quality assessment periodically rather than continuously. It uses motion sensors to detect device movement and triggers network quality assessments based on movement events or time intervals. This periodic approach maintains synchronization adaptability while significantly reducing processing energy consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses built-in motion sensors and existing network stacks to perform self-assessment of device state and network quality. By leveraging already-available hardware and software resources, it achieves adaptability without requiring additional energy-intensive processing or external services.

Inventive Principle:

Principle #25Self-service

AI summary

A method and apparatus for modifying data synchronization of a portable computing device responsive to movement of the portable computing device are disclosed. Data exchange quality associated with multiple locations is captured and stored. A predicted location of a portable computing device is determined from stored data describing previous locations of the portable computing device or navigation data. Data exchange quality associated with the predicted location is retrieved and analyzed to modify data exchange between the portable computing device and a server. For example, if the data exchange quality of the predicted location is low, a fault-tolerant data exchange method is selected or if data exchange is not possible at the predicted location, data exchanges occur more frequently prior to the portable computing device reaching the predicted location.
