On-Vehicle Hands-Free Apparatus Call History Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hands-free apparatuses for vehicles lack convenience in making hands-free calls, as they often rely on built-in applications that do not effectively utilize the phone functions of mobile phones, limiting functionality and user experience.
Innovation Solution
An on-vehicle hands-free apparatus connected to a mobile phone via wireless or wired methods, utilizing a hardware processor to execute calls based on call history and phonebook data, allowing seamless integration with the mobile phone's phone function for both incoming and outgoing calls, and updating call history data after calls are terminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hands-free apparatus uses a built-in application to make calls, then the apparatus can perform hands-free calling function, but the convenience and functionality are limited compared to using the mobile phone's native phone function
Solution Approach 1:
The patent introduces an intermediary mechanism that allows the hands-free apparatus to access and control the mobile phone's native phone function through a communication interface. This intermediary connection enables the hands-free apparatus to utilize the mobile phone's phone function while maintaining hands-free operation, thereby improving both convenience and functionality without requiring the hands-free apparatus to have its own built-in phone application.
2Reliability
If the hands-free apparatus stores call history data locally, then it can display call history without mobile phone connection, but the data may become outdated when disconnected
Solution Approach 1:
The patent implements a feedback mechanism where the hands-free apparatus periodically or event-driven synchronizes call history data with the mobile phone. When the mobile phone connects, the system automatically updates the call history data stored in the hands-free apparatus, ensuring that the displayed information remains current and accurate while maintaining availability even when disconnected.
Solution Approach 2:
The system performs preliminary synchronization of call history data when the mobile phone connects, before any user interaction occurs. This preliminary action ensures that the hands-free apparatus has the most up-to-date call history information ready for immediate display, preventing information loss or outdated data from affecting user experience.
3Adaptability or versatility
If the hands-free apparatus requires data transfer from mobile phone to establish call function, then it can access phone function, but the process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the essential functionality needed for hands-free calling from the mobile phone's phone function and makes it available to the hands-free apparatus through a simplified interface. Instead of requiring complete data transfer and complex integration, the system extracts only the necessary phone function capabilities, reducing the complexity of the data transfer process while maintaining full functionality.
Data Source
AI summary
An on-vehicle hands-free apparatus according to the present disclosure enables a hands-free call by being connected to a mobile phone in a wireless or wired manner. The on-vehicle hands-free apparatus includes a memory, and a hardware processor coupled to the memory. The hardware processor is configured to: cause the mobile phone to execute an outgoing/incoming call using a phone function of the mobile phone based on outgoing/incoming call history data or phone book data stored in the mobile phone, the outgoing/incoming call history data including a phone number transmitted and received by the mobile phone; and acquire the outgoing/incoming call history data including a phone number of a counterpart of a call from the mobile phone when the call is terminated on the mobile phone.
