Solution Overview
Problem
Infants on aircraft may feel uncomfortable and irritable in decompressed cabins and narrow lavatories, making it difficult to change diapers smoothly, and providing a large space for relaxation is challenging.
Innovation Solution
An Aircraft Lavatory Unit with a Movable Diaper Changing Table that can be housed in a wall and pulled out, combined with displays showing soothing images or videos to calm the infant, ensuring a comfortable changing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lavatory interior space is kept narrow to effectively utilize allocated space, then space utilization is improved, but infant comfort and ease of diaper changing deteriorate
Solution Approach 1:
The diaper changing table is designed to be movable rather than fixed. It can be pulled out from the wall to provide adequate working space for diaper changing, and pushed back when not in use to maintain a compact lavatory appearance. This dynamic configuration allows the lavatory to adapt between two states: compact for space efficiency and expanded for operational ease during diaper changing.
Solution Approach 2:
The diaper changing table is segmented from the wall structure, allowing it to be independently moved. The table is divided into a main body portion and a leg portion that can be selectively positioned. This segmentation enables the table to be pulled out only when needed for diaper changing, rather than occupying permanent space, thus resolving the contradiction between space utilization and operational ease.
2Ease of operation
If the lavatory space is expanded to allow infants to relax, then infant comfort is improved, but space utilization efficiency deteriorates
Solution Approach 1:
The movable diaper changing table allows the lavatory to dynamically adjust its functional space. When the table is pulled out, infants have more space to move and relax during diaper changing. When pushed back into the wall, the lavatory maintains its compact size for efficient space utilization. This dynamic adaptation resolves the contradiction by providing expanded space only when actually needed for infant comfort.
Solution Approach 2:
The diaper changing table utilizes the wall depth dimension for storage when not in use, rather than occupying floor space. By pulling the table out from the wall along the depth dimension, adequate space is created for infant comfort during diaper changing without permanently reducing the usable floor area of the lavatory.
3Ease of operation
If the diaper changing table is always pulled out to provide working space, then ease of diaper changing is improved, but space utilization and lavatory compactness deteriorate
Solution Approach 1:
The diaper changing table is designed with movable legs that can be selectively extended or retracted. During diaper changing operations, the legs are extended to provide adequate working space and stability. When not in use, the legs are retracted to allow the table to be pushed back into the wall, maximizing space utilization and maintaining lavatory compactness. This dynamic leg extension mechanism resolves the contradiction between operational ease and space efficiency.
