Vehicle Rearview Mirror Wireless Control System with Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for controlling multiple remote devices, such as garage door openers and security systems, require multiple remote controls, making it difficult to consolidate operations and provide immediate feedback on successful actuation, leading to concerns about unsuccessful operations.
Innovation Solution
A wireless control system integrated with a trainable transceiver and a back-up display in a vehicle, which transmits control signals to remote devices and receives status information, allowing the system to indicate the status of remote devices on the back-up display while reversing, thereby providing immediate feedback on operation success or failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple remote controls are used to control different remote devices, then each device can be controlled independently, but the system complexity increases and ease of operation decreases
Solution Approach 1:
The patent implements a universal remote control system where a single trainable transceiver can learn and store control signals for multiple different remote devices (garage door openers, security systems, etc.). The transceiver is trained by receiving control signals from various devices and storing their characteristics, enabling one device to control multiple functions that previously required separate remote controls.
2Productivity
If conventional remote control systems are used, then control signals can be transmitted to remote devices, but immediate feedback on operation success is not provided
Solution Approach 1:
The patent incorporates a feedback mechanism where the trainable transceiver receives acknowledgment signals from remote devices after transmitting control signals. The system processes these acknowledgment signals to determine whether the control operation was successful and provides immediate visual feedback through display elements (LED indicators showing green for success, red for failure) and audio feedback through the vehicle's audio system, eliminating the uncertainty of whether the remote device responded.
3Adaptability or versatility
If a trainable transceiver is integrated into the vehicle system, then multiple remote devices can be controlled from a single system, but the device complexity increases
Solution Approach 1:
The patent merges the trainable transceiver, acknowledgment signal receiver, status determination logic, and display/audio feedback systems into an integrated vehicle control system. The transceiver is incorporated into existing vehicle components such as the rearview mirror assembly or overhead console, combining multiple functions (control transmission, feedback reception, status monitoring, and user interface) into a unified system that leverages existing vehicle infrastructure.

AI summary
A system for coupling to a vehicle and for causing actuation of a remote device via a control signal transmission includes a transmitter for causing the control signal transmission to the remote device. The system further includes a circuit configured to cause a back-up display to indicate status of the remote device in response to a status determination.
