Automobile Power Seat Boarding Position for Faster Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automobile power seats, users with different physical statures face increased waiting and adjustment times when unlocking the cockpit, as the seat cushion moves from an anti-theft position to a driving position, hindering quick boarding and starting the vehicle, especially in urgent situations like rainy weather.
Innovation Solution
An automobile power seat with a controller that registers different boarding and driving seat positions for each user, allowing the seat cushion to move from an anti-theft position to a shorter-distance boarding position and then to a driving position, with the seatback rotating to a rearward tilt for easier access, and automatically adjusting positions based on seat belt wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the seat cushion moves directly from the anti-theft seat position to the driving seat position, then the driving position is achieved, but the waiting time is excessively long for users with different body sizes
Solution Approach 1:
The patent divides the seat cushion movement into two distinct phases: first moving to a boarding seat position (intermediate stop), then moving to the driving seat position. This segmentation allows users to board the vehicle quickly at the first position while still achieving the final driving position automatically, thereby reducing waiting time without complicating the operation.
Solution Approach 2:
The patent implements a preliminary action by moving the seat cushion to a boarding seat position before the final driving seat position. This intermediate position is prepared in advance as a stopping point that allows users to board the vehicle immediately, while the system continues to complete the full movement to the driving position automatically.
2Productivity
If the seat cushion moves to the driving seat position of the previous user, then the cockpit is unlocked, but users with different physical statures face extended adjustment time
Solution Approach 1:
The movement process is segmented into an intermediate boarding position and a final driving position. The boarding position serves as a quick-access point that reduces the time for cockpit unlocking and user boarding, while the system continues to complete the full movement to the personalized driving position in the background.
Solution Approach 2:
The boarding seat position acts as an intermediary state between the anti-theft position and the final driving position. This intermediate position allows users to quickly access the vehicle interior without requiring the seat to complete the full movement to the driving position, thereby accelerating the cockpit unlocking process.
3Adaptability or versatility
If the seat cushion moves a longer distance to accommodate all users, then all users can reach the driving position, but the waiting time increases
Solution Approach 1:
The patent segments the seat movement into two phases: a first phase to a boarding position that is accessible to all users regardless of body size, and a second phase to individualized driving positions. This segmentation allows the system to maintain adaptability for different users while reducing the initial movement distance to minimize waiting time.
Solution Approach 2:
The system performs a preliminary movement to a boarding position that is optimized for quick access by all users. This preliminary action reduces the initial waiting time, while the system continues to complete the full personalized adjustment in the background, maintaining adaptability without sacrificing speed.

AI summary
An automobile power seat includes: a seat cushion configured to move to an anti-theft seat position, at which it is impossible to board the automobile, at a time of cockpit locking, and, at a time of cockpit unlocking, to move to a boarding seat position at which it is possible to board the automobile, and then to a driving seat position at which it is possible to drive the automobile; and a controller having a storage unit at which the boarding seat position and the driving seat position can be registered differently for each user, the controller being configured to control movement of the seat cushion, wherein a movement distance of the seat cushion from the anti-theft seat position to the boarding seat position is shorter than a movement distance of the seat cushion from the anti-theft seat position to the driving seat position.
