Vehicle Seat Folding Control for Flat Cargo Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with multiple rows of seats, the addition of electric seat adjustment functions to the second row seats complicates the formation of a flat surface for cargo loading, requiring manual readjustment by users.
Innovation Solution
A seat folding system with a folding seat adjustment unit that includes a seat plate adjustment unit, slide adjustment unit, and backrest adjustment unit, controlled by a control unit to automatically adjust the seat to a preset reference state before folding, ensuring a flat surface is formed with the rear seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric seat adjustment function is added to second row seat, then seat adjustment convenience is improved, but difficulty in forming flat surface for cargo loading increases
Solution Approach 1:
The control unit automatically adjusts the second row seat to a predetermined reference state (specific position, angle, and height) before folding occurs. This preliminary positioning ensures that when the seat is folded, it aligns perfectly with the third row seat to form a flat cargo surface, eliminating the need for manual post-adjustment.
Solution Approach 2:
The system uses sensors to detect the positions of the second and third row seats, and the control unit processes this information to automatically adjust the second row seat to the correct reference state. This feedback mechanism ensures precise alignment for forming a flat surface without requiring user intervention.
2Device complexity
If manual seat adjustment method is used, then device complexity is reduced, but time required for seat adjustment increases
Solution Approach 1:
The system enables the second row seat to adjust itself automatically to the predetermined reference state through the control unit and motorized adjustment mechanisms. This self-service capability eliminates the need for manual user adjustment, significantly reducing the time required while maintaining reasonable system complexity.
3Adaptability or versatility
If electric adjustment function is applied to multiple rows, then seat functionality is improved, but difficulty in creating flat cargo area increases
Solution Approach 1:
The control unit receives feedback from sensors about the positions of multiple row seats and automatically calculates and executes the necessary adjustments to bring the second row seat to the correct reference state, ensuring flat surface formation without requiring user coordination between multiple seats.
Solution Approach 2:
The system replaces manual mechanical adjustment with an automated control system that uses motors and sensors to position seats. This substitution of mechanical user操作 with an automated control system maintains high functionality while dramatically improving ease of operation for creating flat cargo areas.
