Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional satellite navigation systems in personal digital assistants require manual on/off switching, leading to user inconvenience and a lack of user-friendly interface.
Innovation Solution
A control system comprising an apparatus body, a tag, a reader, a recognition module, and a processor that automatically turns the satellite navigation apparatus on or off based on recognition data from a tag, transitioning between sleep and wake-up modes without user intervention, utilizing RFID technology for contactless data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual on/off switching is used, then the system structure remains simple, but user convenience deteriorates
Solution Approach 1:
The system automatically detects the presence of a tag near the reader and autonomously activates or deactivates the satellite navigation apparatus without requiring user intervention. The processor monitors tag detection status and automatically transitions between wake-up and sleep modes, making the system serve itself rather than requiring manual user operation.
Solution Approach 2:
The patent replaces the mechanical button-pressing operation with an automated electromagnetic field-based detection system. The reader uses electromagnetic fields to detect tags, and the processor automatically controls system activation/deactivation based on detection results, substituting manual mechanical interaction with automated electronic control.
2Ease of operation
If automatic on/off switching is implemented, then user convenience is improved, but device complexity increases
Solution Approach 1:
The patent introduces a tag as an intermediary element that carries identification information. The reader detects this external tag object to trigger automatic activation, using the tag as a mediator between the user and the system. This allows automatic control while keeping the core system structure relatively simple by leveraging an external lightweight component.
3Speed
If the apparatus remains in wake-up mode continuously, then response speed is improved, but energy consumption increases
Solution Approach 1:
The system dynamically transitions between wake-up mode and sleep mode based on real-time tag detection status. When a tag is detected, the system activates to wake-up mode for fast response; when no tag is present, it transitions to sleep mode to conserve energy. This dynamic state adjustment optimizes both response speed and power consumption according to actual usage conditions.
Solution Approach 2:
The processor periodically checks for tag presence and automatically switches between operational states. Instead of remaining continuously active, the system uses periodic detection to determine when activation is needed, reducing overall energy consumption while maintaining readiness to respond quickly when a tag appears.

AI summary
This invention discloses a control system and method thereof that is applied to a navigation apparatus. The system includes an apparatus body, a tag, a reader, a recognition module, and a processor. The apparatus body is mounted in the navigation apparatus to provide a navigation function. The tag is mounted on an object to provide a recognition data. The reader is used to detect and read the recognition data. The recognition module is used to compare the recognition data with a predetermined recognition data in order to generate a trigger signal. The processor is used to receive the trigger signal and then drives the apparatus body to perform a wakeup mode. If the processor does not receive the trigger signal in a determined period, the processor will drive the apparatus body to perform a sleep mode.
