Vehicle Screen Assembly Ceiling Suspension for Cabin Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen assemblies for vehicles often reduce cabin space and cause passenger discomfort due to their storage and deployment methods, which can lead to reduced head space and elbow space for passengers, and may shift during vehicle movement, eliminating the visual barrier.
Innovation Solution
A screen assembly with a spool and flexible screen that deploys in an arc shape, using pivotally connected arms and a drive motor, allowing for adjustable positions between stored, anchor, and deployed states, maintaining the screen's position during vehicle movement and providing a visual barrier between seats without obstructing passenger space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen assembly is stored between seats using conventional methods, then the screen is readily accessible, but it reduces cabin space and causes passenger discomfort due to reduced head space and elbow space
Solution Approach 1:
The screen assembly is extracted from the conventional between-seat storage location and repositioned to hang from the ceiling structure above the passenger cabin. This extraction removes the screen from the problematic space between seats, eliminating the reduction of head space and elbow space while maintaining accessibility through overhead deployment
Solution Approach 2:
The screen assembly transitions from a horizontal/vertical storage position between seats to a ceiling-suspended vertical deployment position. By utilizing the overhead dimensional space rather than the lateral between-seat space, the screen achieves its barrier function without encroaching on passenger comfort zones
2Reliability
If the screen assembly is fixed in position, then it provides a stable visual barrier, but it cannot adapt to different passenger needs or vehicle movements
Solution Approach 1:
The screen assembly incorporates a dynamic suspension system with cables and pulleys that allow the screen to move and adjust its position. The screen can be raised, lowered, and repositioned to accommodate different passenger needs and vehicle movements, while the suspension mechanism maintains stability when deployed
Solution Approach 2:
The screen assembly allows for parameter changes in position, angle, and tension through its suspension mechanism. The screen can be adjusted to different heights and angles to optimize the visual barrier function for various configurations and movement conditions
3Strength
If the screen uses a rigid structure, then it provides strong support and stability, but it obstructs passenger space and reduces cabin aesthetics
Solution Approach 1:
The screen employs a flexible fabric or mesh material instead of rigid panels. This flexible material provides the necessary visual barrier function while being thin and adaptable, allowing it to conform to the suspension system without creating bulky obstructions in the passenger space
Solution Approach 2:
The flexible screen material dynamically adjusts its shape and tension through the cable suspension system, providing structural support where needed while maintaining an unobtrusive presence that preserves cabin aesthetics and passenger space

AI summary
A screen assembly includes an anchor arm, a cover arm, a spool arm, a spool, and a flexible screen. The anchor arm is connected to a component of the vehicle within the passenger cabin. The spool arm is disposed between the anchor arm and the cover arm. The spool is inserted onto the spool arm and can rotate relative to the spool arm. The flexible screen is attached to the spool and includes first and second portions. The first portion has a first edge attached to the spool arm and a second edge attached to the anchor arm. The second portion includes a first edge attached to the spool arm and a second edge attached to the cover arm. The first and second portions are dispensed in opposite directions when at least one of the cover arm and the anchor arm moves relative to the spool arm.
