Solution Overview
Problem
Modern vehicle seat adjustment systems using electric controls lack integration with a central display device, requiring additional installation space and higher costs due to separate electrical operating elements, and face challenges in providing a simple and intuitive user interface.
Innovation Solution
A method and device that utilize a touchscreen display surface to integrate seat adjustment operations, displaying graphic elements and arrow controls for intuitive movement of seat elements, eliminating the need for mechanical or electrical switches and providing visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate electrical operating elements are arranged on the vehicle seat for adjusting seat elements, then the user can operate the seat adjustments with electric controls, but the installation space in the interior of the vehicle increases and costs increase
Solution Approach 1:
The patent merges the seat adjustment operating elements with the central display device's touch-sensitive surface. Instead of having separate electrical controls on the vehicle seat, the control elements are integrated into the display device, allowing users to adjust seat elements through the touchscreen interface. This combining of functions eliminates the need for additional separate controls, thereby reducing installation space while maintaining ease of operation.
Solution Approach 2:
The central display device with touch-sensitive surface is designed to serve multiple functions: it displays information to the user and simultaneously serves as the control interface for seat adjustments. By making the display device universal and multi-functional, the patent eliminates the need for dedicated separate controls, thus reducing the overall installation space required in the vehicle interior while preserving full operational capability.
2Ease of operation
If separate electrical operating elements are arranged on the vehicle seat for adjusting seat elements, then the user can operate the seat adjustments with electric controls, but the costs increase due to additional components
Solution Approach 1:
The patent combines the seat adjustment control functionality with the existing central display device. By merging these functions, the patent eliminates the need to manufacture and install separate electrical operating elements, thereby reducing component count and manufacturing costs while maintaining the ease of electric control operation.
Solution Approach 2:
The central display device is designed to perform multiple functions including information display and seat adjustment control. This multi-functionality reduces the total number of components needed, lowering both manufacturing and installation costs while preserving the user-friendly electric control interface for seat adjustments.
3Area of stationary object
If a touch-sensitive display surface is used for seat adjustment controls, then the operating concept is integrated and installation space is reduced, but the interface must be simple and intuitive which presents a challenge
Solution Approach 1:
The patent implements visual feedback by displaying graphic elements on the touchscreen that represent the current position and state of the seat elements. When the user interacts with the control interface, the display provides immediate visual confirmation of the selected function and the resulting changes in seat position. This feedback mechanism makes the touch-sensitive interface more intuitive and easier to operate by keeping the user informed about the system state.
Solution Approach 2:
The patent uses graphic elements on the display that visually copy or represent the physical seat elements and their positions. This visual representation creates a direct visual correspondence between what the user sees on the screen and the actual physical state of the seat, making the interface more intuitive and easier to understand without requiring separate physical controls.
