Removable Seat Cover With Folding Screen For Public Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public transport seats lack privacy and comfort due to close seating arrangements, which can lead to vulnerability and increased disease transmission, while adding privacy features like screens can obstruct passage and increase costs.
Innovation Solution
A removable seat cover with a folding screen, traction means, and additional cushion elements that can be interposed between the user and the backrest to enhance privacy without obstructing passage, comprising a first cover element with a support face, a set of panels that fold in a fan shape, and traction means to hold the screen in position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a screen is added to the seat to increase privacy, then user privacy and comfort are improved, but the screen obstructs passage and complicates seat structure
Solution Approach 1:
The seat cover is divided into multiple independent elements: a first cover element for the headrest, a second cover element for the backrest, and a foldable screen with multiple panels. This segmentation allows each component to perform its specific function while maintaining overall simplicity and ease of installation.
Solution Approach 2:
The screen is designed to be foldable with multiple panels that can be stacked against each other along a stacking direction. When unfolded, the screen extends towards the front of the seat to provide privacy; when folded, the panels are stacked to minimize obstruction and facilitate user movement. This dynamic configuration resolves the contradiction between privacy provision and passage obstruction.
2Object-affected harmful factors
If fixed privacy features are installed on seats, then user privacy is improved, but ease of movement and emergency evacuation are compromised
Solution Approach 1:
The screen is designed as a foldable structure with multiple panels that can be quickly collapsed and stacked. When not in use, the screen panels are stacked against each other along a stacking direction, creating a compact configuration that does not obstruct passage or hinder emergency evacuation. This dynamic design allows the screen to provide privacy when needed while maintaining ease of movement when folded.
3Object-affected harmful factors
If screens are added to increase perceived privacy, then user comfort is improved, but the number of obstacles increases preventing quick evacuation
Solution Approach 1:
The foldable screen design allows for rapid deployment and collapse. In case of emergency, the screen can be quickly folded and stacked, removing any obstruction to evacuation paths. The screen panels are connected in a way that allows them to be collapsed sequentially, ensuring that the structure can be rapidly disassembled without compromising safety or evacuation efficiency.
Solution Approach 2:
The screen is designed as a removable and foldable component that can be easily collapsed and stored when not in use. This extraction approach ensures that the privacy feature does not permanently occupy space or create obstacles in the evacuation path, maintaining safety while providing privacy when needed.
