Integrated Vehicle Switch Device with Mode-Based Interface Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle switch systems are cumbersome for drivers due to the large number of individual switches required for functions like door lock/unlock, power mirror angle adjustment, mirror folding, integrated memory system, and engine start/stop, leading to operational inconvenience and increased manufacturing costs.
Innovation Solution
An integrated switch device with a single input button, touch button, and touch screen, controlled by a controller that determines operation modes based on vehicle state and user inputs, allowing seamless transitions between door control, mirror adjustment, IMS settings, and engine start/stop functions through intuitive swipe gestures and fingerprint authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual switches are installed for door lock/unlock, power mirror angle adjustment, mirror folding, IMS, and engine start/stop functions, then each function can be operated independently and reliably, but the number of switches becomes too large for the driver to handle conveniently and manufacturing cost increases
Solution Approach 1:
The patent combines multiple individual switches (door lock/unlock switch, power mirror angle adjustment switch, mirror folding switch, IMS switch, and engine start/stop button) into a single integrated switch device. This consolidation reduces the number of separate components while maintaining all individual functions, thereby improving operational convenience without sacrificing functional reliability.
Solution Approach 2:
The integrated switch device is designed to perform multiple functions through a single unified interface. The single switch incorporates door control, mirror adjustment, memory system access, and engine start/stop capabilities, allowing one component to serve universal purposes that previously required multiple dedicated switches.
2Reliability
If multiple individual switches are manufactured separately, then each switch can be optimized for its specific function, but the manufacturing cost of the vehicle increases
Solution Approach 1:
The patent consolidates multiple individually manufactured switches into a single integrated switch device. This merging reduces the total number of components that need to be manufactured, assembled, and inventoried, thereby lowering manufacturing costs while maintaining all necessary functions through a unified design.
Solution Approach 2:
By designing a universal switch that handles multiple functions, the patent eliminates the need to manufacture separate specialized switches for each function. This multi-functional approach reduces manufacturing complexity and cost while preserving the reliability of each individual function through integrated control.
3Ease of operation
If a single integrated switch device is used for multiple functions, then the number of switches is reduced and manufacturing cost decreases, but the complexity of controlling and managing multiple functions through one interface increases
Solution Approach 1:
The integrated switch device is controlled by a controller that segments and manages different functions through distinct operation modes. The controller activates specific modes (first mode for door lock/unlock and mirror folding, second mode for mirror angle adjustment, third mode for IMS settings, fourth mode for engine start/stop) based on user input, thereby organizing complex functionality into manageable segments.
Solution Approach 2:
The switch device employs dynamic mode switching to adapt its functionality based on user interaction. The controller dynamically activates different operation modes depending on the function being accessed, allowing the single switch to seamlessly transition between multiple functions without requiring the user to manage complex settings manually.

AI summary
An integrated switch device for a vehicle includes: an input device configured to receive a user's fingerprint; a touch device configured to generate a mirror angle adjustment signal; a touch display configured to display a door control interface, a mirror selection interface, a mirror control interface, and a seat setting interface; and a controller configured to determine an operation mode based on whether the vehicle in a driving mode, a power condition, and whether a door is open and to set an interface displayed on the touch display among the door control interface, the mirror selection interface, the mirror control interface, and the seat setting interface depending on the operation mode.
