Voice-Controlled Vehicle Seat Adjustment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power-adjustable vehicle seat control systems are complex, lack intuitive operation, especially in hidden locations, and fail to provide visual feedback or safety limitations, making them difficult to use and potentially unsafe.
Innovation Solution
A control system that integrates voice input, touchscreen interaction, and a processor to interpret commands for seat adjustments, providing visual feedback and safety limitations, allowing hands-free operation and intuitive control of multiple seat adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical buttons and switches are used for seat adjustment control, then the control system is simple and reliable, but the operation becomes complex and non-intuitive especially in hidden locations
Solution Approach 1:
The patent replaces physical mechanical buttons and switches with voice recognition and touchscreen interfaces. The voice input device captures vocal commands, the processor interprets these commands, and the touchscreen display provides visual feedback, eliminating the need for complex physical button arrays in hard-to-reach locations while maintaining simple and intuitive operation.
Solution Approach 2:
The patent introduces a touchscreen display as an intermediary between the user and the seat adjustment system. This display provides visual feedback and confirmation of adjustment commands, making the system more intuitive by showing users what actions are being performed without requiring them to physically locate and manipulate hidden buttons.
2Loss of information
If physical buttons are used for seat adjustment, then the control system is simple, but visual feedback for adjustment commands is not provided
Solution Approach 1:
The patent implements a feedback mechanism where the touchscreen display visually confirms seat adjustment commands and shows the current status of seat positions. When a user issues a voice command or touches the screen, the system provides visual feedback indicating that the command was received and is being executed, preventing information loss about system state.
3Reliability
If conventional button controls are used, then the system is simple, but safety limitations for adjustments cannot be provided
Solution Approach 1:
The patent implements preliminary safety checks before executing seat adjustment commands. The processor evaluates multiple conditions including occupant presence detection, seatbelt status, and proximity to other objects before allowing adjustment. This preliminary evaluation prevents unsafe adjustments from occurring in the first place, enhancing reliability without requiring complex additional hardware.
4Ease of operation
If voice control is implemented for seat adjustment, then hands-free operation is enabled, but the system complexity increases
Solution Approach 1:
The patent replaces manual button pressing with voice recognition technology. The voice input device captures spoken commands, the processor interprets these vocal inputs and converts them into control signals for seat adjustment. This substitution enables hands-free operation while the integration with existing touchscreen and display systems keeps the overall complexity manageable.

AI summary
A control system for a vehicle having a seat with a first moveable portion and an adjustment actuator coupled with the first moveable seat portion includes a voice input device, a touchscreen input device, and a controller in communication with the adjustment actuator, the voice input device, and the touchscreen input device. The controller has a processor programmed to interpret a first adjustment command from one of a voice command received from the voice input device and a manual command received from the touchscreen input device, carry out a first seat adjustment by causing the adjustment actuator to move the first moveable seat portion according to the first adjustment command, and to present information related to the first adjustment command on the touchscreen.
