Vehicle Seat Backrest Touch Interface for Easy-Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats with manual handles require a free hand and significant force to operate, making it difficult for injured, elderly, children, or individuals carrying items to easily transition the seat into an easy-entry position.
Innovation Solution
A touch-sensitive operating device integrated into the vehicle seat's backrest, featuring a display element and input device for intuitive operation, allowing for reduced force requirements and enabling automatic execution of functions without continuous manual actuation, with the option for different function assignments and language support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual handle connected to a backrest lock by Bowden cable is used, then the vehicle seat can be transferred into a forward-pivoted non-use position, but significant force is required to operate the handle and a free hand is needed
Solution Approach 1:
The patent replaces the manual mechanical handle operation with an electric motor-driven system. The operating device includes a motor that automatically pivots the backrest between use and non-use positions, eliminating the need for manual force application to the Bowden cable mechanism.
Solution Approach 2:
The system performs the backrest positioning function automatically through the motor-driven mechanism. The seat adjusts its own position without requiring external manual intervention, making the system self-servicing for the positioning function.
2Adaptability or versatility
If a manual handle is used for operating the backrest lock, then the seat can be moved to non-use position, but operation is difficult for injured people, old people, children, or people carrying items
Solution Approach 1:
The electric motor-driven operating device replaces the manual mechanical handle, making the system accessible to users who cannot physically operate a manual handle, including injured people, elderly, children, or those carrying items.
Solution Approach 2:
The motor-driven operating device provides universal accessibility for all user groups. The control interface can be operated with minimal force and can be positioned for easy access, making it suitable for diverse users with varying physical capabilities.
3Ease of operation
If a touch-sensitive input device with display element is integrated into the upholstery, then intuitive operation with minimal force is achieved, but the device complexity increases
Solution Approach 1:
The touch-sensitive input device with display element serves as an intermediary interface between the user and the motor-driven mechanism. It provides intuitive control through tactile feedback and visual display, simplifying user interaction while managing the underlying system complexity.
Solution Approach 2:
The operating device integrates multiple functions into a single unit: the touch-sensitive input device, the display element, and the motor control are combined in one compact assembly integrated into the upholstery, reducing overall system complexity despite adding intelligent control capabilities.
