Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aisle seats in vehicles like airplanes, buses, and trains are susceptible to damage and dirt from technicians and equipment during maintenance and repairs due to their proximity to aisles, which are confined spaces that make maneuvering difficult and increase the likelihood of accidental contact.

Innovation Solution

A seat cover design comprising a headrest cover, armrest cover, and side cover portion that extends along the seat back, protecting the seat from damage and dirt while allowing access for maintenance and tests, with removable and customizable materials like nylon, polyester, vinyl, and leatherette.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If seat covers fully cover the entire seat including armrests and headrests, then protection from damage and dirt is improved, but access for maintenance and testing becomes more difficult

Engineering Contradiction:

Improvedamage and dirt to seatVSAvoidaccess for maintenance and testing

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The seat cover is divided into multiple separate components: a main seat cover for the seat cushion and backrest, an armrest cover for the armrest, and a headrest cover for the headrest. This segmentation allows each component to be independently installed and removed, providing full protection when needed while enabling selective removal for maintenance access without compromising overall protection capability.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If aisle seats are left uncovered to maintain passenger comfort and functionality, then access for maintenance becomes easier, but protection from damage and dirt during maintenance is reduced

Engineering Contradiction:

Improveaccess for maintenanceVSAvoiddamage and dirt to seat

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The seat covers are installed on the seat before maintenance activities begin. This preliminary protection allows technicians to work on the seat with full access to all surfaces while the covers prevent dirt, grease, and damage from transferring to the seat materials during maintenance operations.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If seat covers are designed to fully cover the seat for maximum protection, then protection from damage is improved, but the seat appears less accessible and inviting for passenger use

Engineering Contradiction:

Improvedamage to seatVSAvoidpassenger comfort and functionality

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The seat cover system is designed to be dynamically configurable - covers can be installed when the seat is not in use (during maintenance, storage, or non-passenger periods) and removed when passengers need to use the seat. This dynamic approach allows the seat to transition between protected and accessible states, maintaining both protection capability and passenger usability.

Inventive Principle:

Principle #15Dynamics

AI summary

Example implementations relate to seat covers and techniques for using such seat covers to partially cover and protect aisle seats on airplanes, buses, trains, and within other venues. An example seat cover for partially covering a seat includes a headrest cover configured to extend over a headrest of the seat, an armrest cover configured to extend over an armrest of the seat positioned proximate the aisle of the vehicle. The armrest cover includes a side surface that extends from the armrest of the seat to a position below a seat cushion of the seat when the seat cover is used to partially cover the seat. The seat cover also includes a side cover portion coupling together the headrest cover and the armrest cover, wherein the side cover portion is configured to extend along a side of a seat back of the seat.
