Solution Overview

Problem

The safety risk associated with drivers operating their mobile phones during driving, such as answering calls or viewing messages, is significant due to the need to look away from the road.

Innovation Solution

A driving recorder is connected to a terminal device via wireless communication, allowing it to display the terminal's interface and control operations on the recorder's screen, enabling users to manage calls and messages without directly handling the phone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user operates the mobile phone directly during driving, then the user can perform dialing, answering calls, and viewing messages, but the driving safety deteriorates due to the need to look away from the road

Engineering Contradiction:
Improvemobile phone operationVSAvoiddriving safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The driving recorder serves as an intermediary device between the mobile phone and the driver. It receives interface data from the mobile phone via wireless communication and displays it on its own screen, allowing the driver to interact with phone functions without directly handling the phone. The recorder can also receive control signals from the driver and transmit corresponding control instructions to the mobile phone, enabling indirect operation while maintaining driving safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The driving recorder creates a visual copy of the mobile phone's interface by receiving and displaying interface data on its screen. This copy includes call interfaces, message interfaces, and other terminal interfaces, allowing the driver to view and interact with phone content through the recorder's display rather than the phone itself, thereby eliminating the need to look down at the phone during driving.

Inventive Principle:
Principle #26Copying

2Reliability

If the driving recorder displays the terminal interface, then the driver can view messages and calls without handling the phone, but the device complexity increases due to wireless communication and interface integration requirements

Engineering Contradiction:
Improvedriving safetyVSAvoidsystem integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The driving recorder is designed with multi-functionality to justify the increased complexity. It not only displays terminal interfaces but also receives control signals, transmits control instructions to the mobile phone, and provides audio output through integrated speakers. This universal design allows a single device to handle multiple driving assistance functions, making the added complexity worthwhile for the significant safety improvement.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present application provides a display method, a display apparatus and a driving recorder, which relates to the field of communication technology. The method includes: establishing (201) a communication connection with a terminal device; receiving (202) interface data sent from the terminal device through the communication connection; displaying (203) the terminal interface in a display screen according to the interface data; receiving (204) a control signal of acting on the driving recorder; and controlling (205) the terminal device according to the control signal. The present disclosure solves a problem of large safety risk caused by a user operating his/her mobile phone in the process of driving. Since the user may directly view the message of the terminal device in the display screen of the driving recorder and perform appropriate operations during the driving process, without operating the terminal device, safety of driving is improved.
