Detachable Vehicle Control Device for Simplified Function Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of control systems in vehicles, particularly due to the increasing number of functions and multimedia capabilities, leads to cumbersome user interfaces and reduced usability, especially when passengers are present, as traditional central-control-point based systems require multiple manipulation steps and voice recognition usage rates are low.
Innovation Solution
A vehicle function control system utilizing detachable control devices with wireless transceivers and attachment units that allow users to attach and detach devices magnetically, establishing data paths for controlling various vehicle functions through intuitive manipulation, enabling easier access and control of vehicle functions without the need for complex menus or voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central-control-point based tree-type menu structure is used to control vehicle functions, then comprehensive function control is achieved, but the manipulation steps become complicated and user convenience deteriorates
Solution Approach 1:
The control system is segmented into multiple attachment positions, each independently controllable with its own detachable control device. This divides the complex centralized control into simpler distributed control units, reducing manipulation steps while maintaining comprehensive function control across different vehicle zones
Solution Approach 2:
The patent introduces a spatial dimension to control by providing multiple attachment positions at different locations (e.g., driver side, passenger side, rear seats). This transforms the traditional single-point control into a multi-dimensional control layout, allowing users to access functions from various positions without navigating complex menus
2Ease of operation
If voice recognition function is used for control, then manipulation steps are simplified, but usage rate is remarkably reduced when passenger is present
Solution Approach 1:
The detachable control device acts as an intermediary between the user and the vehicle's control system. It provides a physical interface that can be attached to multiple positions, serving as a mediator that works effectively in both driver-only and passenger-present scenarios, unlike voice recognition which fails when passengers are present
Solution Approach 2:
The detachable control device is designed to be universally applicable across different usage scenarios. It can be attached to various positions in the vehicle and controls functions relevant to each position, making it equally effective whether the driver is alone or has passengers, thus achieving high adaptability across different situations
3Loss of information
If display size is increased to show more information, then information display capability is improved, but device complexity and space requirements increase
Solution Approach 1:
Instead of using one large display, the patent segments the display function across multiple smaller detachable control devices positioned at different locations. Each device displays information relevant to its position, distributing the information display task and reducing the complexity of any single display unit while collectively providing comprehensive information coverage
Solution Approach 2:
Each detachable control device at a specific attachment position displays information locally relevant to that position (e.g., driver-related info at driver position, passenger info at passenger position). This localizes the information display quality to match user needs at each position, reducing unnecessary information complexity while maintaining comprehensive information availability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances user convenience by simplifying the control of vehicle functions, allowing for intuitive control without the need for complex manipulation steps, improving usability and reducing the number of physical switches, and enabling multiple functions to be controlled through stacked or positioned detachable devices.
Implementation Method 1

AI summary
Disclosed is a user interface capable of controlling various functions of a vehicle, and more particularly a vehicle function control system and a control method using a detachable control device. A method of controlling an integrated control unit includes: recognizing a first detachable control device attached to a first attachment position among at least one attachment position provided at an attachment unit; establishing a first data path with the first detachable control device; transmitting information about a first function to be controlled corresponding to the first attachment position to the first detachable control device through the first data path; and when receiving first manipulation information from the first detachable control device, controlling the first function to be controlled based on the first manipulation information.
