Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in accurately determining the detection accuracy of position detectors, such as GPS receivers, which affects communication efficiency, especially when moving from outdoor to indoor environments where satellite signal strength deteriorates.
Innovation Solution
The electronic device employs a control method that reduces communication with other devices when the detection accuracy of the position detector deteriorates, using a combination of sensors like accelerometers, geomagnetic sensors, and temperature sensors to estimate the user's environment and adjust communication accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication with another device is maintained continuously, then communication efficiency is improved, but power consumption increases and unnecessary notifications occur when detection accuracy deteriorates
Solution Approach 1:
The communication control unit dynamically adjusts communication frequency based on real-time detection accuracy status. When detection accuracy deteriorates, the system automatically reduces communication frequency to minimize power consumption while maintaining essential connectivity. This dynamic adaptation resolves the contradiction by making communication efficiency contingent on actual detection needs rather than maintaining constant communication.
Solution Approach 2:
The system changes the communication parameter (communication frequency) based on the detection accuracy status. When the position detector's accuracy deteriorates below a threshold, the communication control unit modifies the communication frequency parameter to reduce power consumption. This parameter adjustment directly addresses the contradiction by linking communication intensity to actual detection performance.
2Use of energy by moving object
If communication frequency is reduced when detection accuracy deteriorates, then power consumption is reduced, but communication efficiency may worsen
Solution Approach 1:
The communication control unit continuously monitors detection accuracy status and uses this feedback to adjust communication frequency. When detection accuracy improves, communication frequency increases; when it deteriorates, frequency decreases. This feedback mechanism ensures that communication efficiency is optimized based on actual detection needs, resolving the contradiction by making power consumption and communication efficiency mutually adaptive rather than opposing.
3Measurement precision
If the system uses multiple sensors to estimate environment, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system employs multiple sensors (accelerometer, geomagnetic sensor, temperature sensor) that serve dual purposes: they provide detection data for position accuracy assessment and simultaneously estimate the user's environment (indoor/outdoor status). This multi-functionality resolves the contradiction by extracting multiple benefits from the same sensor suite, improving detection accuracy without proportionally increasing device complexity.
Solution Approach 2:
The environment estimation function merges data from multiple sensors to create a comprehensive view of user context. By combining accelerometer, geomagnetic, and temperature sensor data, the system achieves accurate environment classification that complements position detection. This merging approach improves measurement precision while avoiding the complexity of separate dedicated sensors for each function.
