Rolling Inflatable Partition Wall for RV Space Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partition walls for recreational vehicles and mobile homes are too large and unsuitable for outdoor use due to their size and lack of insulation, and existing movable partitions are not convenient for transport and assembly.
Innovation Solution
A rolling inflatable wall system with a housing, roller, and inflatable wall body that can be pulled out and inflated to form a partition, featuring a torsion spring for automatic retraction, hooks for attachment, and clips for length adjustment, providing insulation and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fixed partition walls are used, then insulation performance is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The partition wall transitions from a static fixed structure to a dynamic system that can be inflated and deflated. The inflatable wall body allows the partition to be deployed when insulation is needed and compacted when portability is required, resolving the contradiction between insulation performance and portability.
Solution Approach 2:
The physical state of the partition wall is changed by inflating or deflating the wall body. When inflated, the wall provides insulation; when deflated, it becomes compact and portable. This parameter change (volume/pressure) allows the same structure to provide both insulation and portability at different times.
2Weight of moving object
If movable partition walls are used, then portability is improved, but insulation performance and structural stability deteriorate
Solution Approach 1:
The partition wall uses an inflatable membrane structure that, when inflated, provides sufficient insulation and structural stability. The flexible shell maintains its shape and thermal properties when pressurized, resolving the contradiction between portability and insulation performance.
3Ease of operation
If traditional movable partitions are used, then ease of operation is improved, but adaptability to different spaces deteriorates
Solution Approach 1:
The inflatable partition wall can be adjusted to various lengths by controlling the inflation of multiple segments, allowing it to adapt to different space requirements while maintaining ease of operation through simple inflate/deflate mechanisms.
Solution Approach 2:
The partition wall is divided into multiple inflatable segments that can be independently controlled. This segmentation allows the partition to be adjusted to different lengths and configurations, improving adaptability to various spaces while maintaining operational simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system offers a portable, easily adjustable, and insulated partition solution suitable for outdoor use, with automatic retraction and secure attachment, enhancing usability in recreational vehicles and mobile homes.
Implementation Method 1
a shaft with a torsion spring may be inside the roller, one end of the torsion spring may be fixed with the shaft, and another end of the torsion spring may be fixed with inner wall of the roller
Implementation Method 2
the pulled-out portion of the inflatable wall body may be inflated to form the pulled-out portion a partition wall

AI summary
A kind of partition wall is introduced. The partition wall includes a housing, a roller wound with an inflatable wall body mounted inside the housing, and a shaft with a torsion spring mounted inside the roller. The inflatable wall body can be pulled out from the housing and can be rolled back to the housing by the torsion spring. The partition wall is rollable which offers people the chance to adjust their room space segmentation. It is also suitable for some small space such as a recreational vehicle or some mobile house. When people need to divide a bedroom from living room, they can expand out the partition wall.
