Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retractable and roll-up wall systems require additional time and expense for deploying and removing framework, and often fail to provide adequate sound resistance, especially when creating smaller independent spaces with flexibility in space division.
Innovation Solution
A flexible, sound-attenuating roll-up wall system that interlocks at various angles without corner structures, using mass loaded vinyl material and an interlocking connector system to reduce sound transfer and facilitate easy deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional framework deployment is used for retractable walls, then structural stability is improved, but deployment time and expense increase
Solution Approach 1:
The patent removes the permanent corner framework from the system, extracting only the essential support function needed during deployment. The walls self-support through mutual interlocking during the deployment process, eliminating the need for persistent corner structures that traditional systems require.
Solution Approach 2:
The walls are pre-equipped with interlocking edges and attachment mechanisms that enable them to self-assemble and support each other during deployment. This preliminary preparation allows the walls to create their own structural stability without requiring external framework support.
2Adaptability or versatility
If traditional flexible wall material is used, then flexibility in space division is improved, but sound resistance deteriorates
Solution Approach 1:
The patent employs composite wall construction combining flexible fabric or vinyl outer layers with sound-absorbing core materials such as foam, fiberfill, or acoustic panels. This composite structure maintains the flexibility and ease of deployment characteristic of traditional flexible walls while adding effective sound attenuation properties.
3Strength
If corner posts are used for wall intersections, then structural support is improved, but device complexity increases
Solution Approach 1:
The patent merges the corner support function into the wall panels themselves through interlocking edges and mutual attachment mechanisms. Instead of separate corner posts, the wall panels combine their structural roles to provide support at intersections, reducing the number of distinct components needed.
Solution Approach 2:
The wall system performs its own structural support function through self-interlocking mechanisms. The walls attach to and support each other directly at intersections without requiring external corner posts or framework, making the system self-sufficient during deployment.
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
Enables efficient division of space with reduced sound transfer and eliminates the need for corner posts, providing greater flexibility and sound attenuation without the added time and expense of traditional deployment methods.
Implementation Method 1
Sound-attenuation is defined as reducing the level of sound that passes through a medium. In the instance of the material used in this invention, mass loaded vinyl, the material absorbs the energy created by sound waves thus reducing the transference of sound from one side of the material to the other side.

AI summary
The present invention is directed to a roll-up, flexible, sound-attenuating wall system. More particularly, this invention relates to a retractable wall system and its components which may be used to divide existing larger spaces into smaller spaces with sound-attenuating barriers. In each unit the flexible, sound-attenuating wall is attached to a receiver tube which, when turned on its axis, deploys or retracts the flexible, sound-attenuating wall. The flexible, sound-attenuating wall is guided by a guide roller to intersect with other flexible, sound-attenuating walls at various angles. The receiver tube and guide roller are attached at either end to independent support brackets. This invention discloses a plurality of interlocking connector systems for connecting a plurality of flexible, sound-attenuating walls at various angles. Further, this invention discloses a winding mechanism disposed in and attached to receiver tube which turns the receiver tube on its longitudinal axis to deploy or retract the flexible, sound-attenuating wall.
