Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS, cellular, Wi-Fi, and Bluetooth triangulation are used to determine location, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent segments the location determination process by using different positioning methods for different scenarios. GPS is used when outdoor location is needed, while Wi-Fi and Bluetooth triangulation are used for indoor location determination. This segmentation allows the system to achieve high measurement precision when needed while managing power consumption by selecting the appropriate method for the current context.
Solution Approach 2:
The patent implements dynamic selection of positioning methods based on the mobile device's location context. The system dynamically switches between GPS, cellular triangulation, Wi-Fi triangulation, and Bluetooth triangulation depending on whether the device is indoors or outdoors, and which signals are available. This dynamic approach optimizes the balance between measurement precision and power consumption.
2Adaptability or versatility
If user location data is shared with service providers, then adaptability of services is improved, but loss of information increases
Solution Approach 1:
The patent introduces a privacy management framework that acts as an intermediary between the mobile device and service providers. This framework controls and manages the sharing of location data, allowing services to be customized based on location information while protecting user privacy through controlled data disclosure. The intermediary mechanism enables service adaptability without complete loss of user privacy information.
3Measurement precision
If multiple positioning methods are used simultaneously, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the positioning system into multiple independent modules (GPS module, cellular triangulation module, Wi-Fi triangulation module, Bluetooth triangulation module). Each module operates independently and can be selected based on the current location context. This segmentation reduces overall system complexity by allowing modular operation rather than requiring all methods to operate simultaneously in an integrated complex system.
Solution Approach 2:
The patent implements dynamic selection and activation of positioning methods based on environmental conditions and signal availability. Rather than maintaining all positioning systems actively running at all times, the system dynamically activates only the necessary positioning methods for the current situation, reducing device complexity while maintaining measurement precision when needed.
