Vehicle Seat Partition Wall With Retractable Privacy and Sun Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In passenger transport vehicles, existing partition walls are bulky, non-modular, and reduce space, making it difficult for passengers to isolate themselves or communicate comfortably, while shared sun protection screens can cause conflicts.
Innovation Solution
A vehicle seat design featuring a partition wall that retracts into a housing, deployable to provide isolation or sun protection, and modular to allow passengers to share space, with independent movement of partition walls and armrests for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If partition walls are installed between seats to allow passenger isolation, then passenger privacy and comfort are improved, but the partition walls are bulky and reduce available space
Solution Approach 1:
The partition wall is designed to be movable between a retracted position (stored in the receiving recess) and a deployed position (extending between the backrest and armrest). This dynamic configuration allows the partition to provide privacy when needed while being compact when not in use, resolving the contradiction between providing isolation and maintaining space availability.
Solution Approach 2:
The partition wall is housed within the receiving recess defined by the rigid shell when not in use. This nesting arrangement allows the partition to be stored compactly within the existing seat structure, minimizing its impact on available space while still providing the function of passenger isolation when deployed.
2Object-affected harmful factors
If fixed partition walls are installed to provide isolation, then passenger privacy is improved, but the partitions are not adjustable and reduce communication ability
Solution Approach 1:
The partition wall's movability between retracted and deployed positions provides adaptability. Passengers can adjust the partition configuration based on their needs - using it for privacy when required and retracting it to enable communication with other passengers, thus resolving the contradiction between privacy and communication flexibility.
3Volume of moving object
If shared sun protection screens are used between rows of seats, then space is saved, but conflicts arise and passenger comfort is reduced
Solution Approach 1:
The sun protection function is segmented and assigned to individual seats through the partition wall, rather than using a shared screen between rows. Each seat has its own deployable partition that can be independently controlled, eliminating conflicts while maintaining space efficiency through the retracted/deployed mechanism.

AI summary
The seat (12) comprises: a seat (14), a backrest (16) having a first side face (32), a rigid shell (18) having a side edge (40), a receiving recess (42) defined between said side edge (40) and the first side face (32), an armrest (20) movable between a stowed position in which the armrest (20) is received in the receiving recess (42) and a usable position, a partition (22) movable between a retracted position and an extended position in which the partition (22) extends between the first side face (32) of the backrest (16) and a free front edge (46) of the armrest (20) in the usable position. The partition (22) in the retracted position is housed in the receiving recess (42).
