Vehicle Remote Key with Capacitive Touch and Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control keys face challenges in ensuring secure locking or unlocking of vehicle doors and trunks, often requiring multiple button presses to confirm the action.
Innovation Solution
A vehicle remote control system with a key fob that establishes a short-range wireless connection to a control assembly, featuring capacitive touch screens, a gravity sensing module, and a lighting module, allowing for intuitive control and confirmation of locking/unlocking operations through touch commands and display of vehicle information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple button presses are required to confirm locking/unlocking, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the remote control key displays visual confirmation (through display panels) and provides tactile feedback (through vibration motors) to indicate whether the locking/unlocking action was successfully received by the vehicle. This allows users to confirm the action status without requiring multiple button presses, resolving the contradiction between security confirmation and ease of operation.
2Device complexity
If traditional button interfaces are used, then device complexity is reduced, but ease of operation deteriorates due to ambiguous feedback
Solution Approach 1:
The patent employs display panels that change visual output (color, icon, or text display) to provide clear feedback about the locking/unlocking status and communication state of the remote control key. This visual feedback mechanism enhances ease of operation without significantly increasing device complexity, as the display can be integrated into the existing key fob structure.
Solution Approach 2:
The remote control key incorporates vibration motors that automatically provide tactile feedback to the user based on the communication status with the vehicle. The system self-services the feedback function without requiring additional manual intervention or complex user interaction, maintaining simplicity while improving ease of operation.

AI summary
A vehicle remote control key for controlling a vehicle, includes a main body, a handle portion, a control module, a displaying module, a terminal communication module and a touch module. The main body includes a first display panel and at least one touch screen. The handle portion is connected to the main body. The terminal communication module is electrically connected to the control module. The display module is electrically connected to the first display panel and the control module, the terminal communication module sends vehicle information to the control module, and the vehicle information is displayed on the first display panel via the display module, the touch module is electrically connected to the at least one touch screen and the control module, when the vehicle is in a parked state, it can be controlled via touching of the touch screen.
