Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless beacon technology is used for micro-location and proximity sensing, then location-based applications can be enabled, but accurate location determination becomes difficult especially in indoor environments

Engineering Contradiction:
Improvelocation-based applicationsVSAvoidlocation determination accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent combines multiple positioning approaches (GPS for outdoor, Wi-Fi triangulation and cellular tower triangulation for indoor) into a unified positioning system. The mobile device can switch between or combine these methods depending on the environment, thereby achieving accurate location determination both indoors and outdoors while enabling comprehensive location-based applications.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If beacon devices broadcast continuously for location tracking, then location tracking capability is maintained, but power consumption increases

Engineering Contradiction:
Improvelocation tracking capabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous broadcasting, the beacon device transmits location information at periodic intervals. The mobile device receives these periodic updates and maintains location tracking capability without requiring constant communication. This periodic transmission approach keeps the tracking reliable while significantly reducing the power consumption compared to continuous broadcasting.

Inventive Principle:
Principle #19Periodic action
