Privacy Enclosure Gap Sealing with Flexible Nontransparent Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing privacy enclosures, such as public restroom partitions, often have gaps between the door and pilasters that compromise user privacy, allowing external visibility when the door is closed.
Innovation Solution
A privacy enhancer composed of a rigid and flexible nontransparent plastic strip with adhesive and connectors is applied to the pilasters and door, closing the gaps between the door and pilasters without restricting door movement, using a two-sided adhesive tape for secure attachment and a diffusing strip to obscure visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hinged doors are used in privacy enclosures, then the door can open and close freely, but perimeter gaps of 1 inch or more are created at the jamb sides when the door is closed, compromising privacy
Solution Approach 1:
The patent applies flexible privacy strips made of thin film material to the edges of the door and/or jamb. These flexible strips can be attached to the hinged door or the jamb, extending into the gap area to block external views while allowing the door to open and close freely without restriction. The thin film nature of the strip allows it to conform to the door movement while maintaining privacy coverage.
2Object-affected harmful factors
If the gap between door and pilaster is reduced to improve privacy, then external visibility is blocked, but door movement may be restricted
Solution Approach 1:
The patent employs dynamic privacy solutions where the privacy strip is attached in a manner that allows it to move with the door. The strip can be positioned to close the gap when the door is closed, yet flex or retract when the door opens, ensuring continuous privacy protection without impeding door operation. This dynamic adjustment resolves the conflict between gap reduction and door movement freedom.
3Strength
If traditional partition systems with metal panels and specialized brackets are used, then structural strength is improved, but manufacturing complexity and installation difficulty increase
Solution Approach 1:
The patent segments the privacy enhancement into separate, modular components - specifically the privacy strips that can be independently attached to the door or jamb without requiring modification of the entire partition structure. This segmentation allows the existing strong metal panel structure to be retained while adding privacy functionality through simple, separate attachments, thereby reducing manufacturing and installation complexity.
Solution Approach 2:
The patent introduces privacy strips as intermediary elements between the existing door/jamb structure and the external environment. These strips serve as a mediating component that blocks views without requiring structural changes to the original partition system, maintaining the strength of the metal panels while simplifying the overall system by avoiding specialized brackets and complex assemblies.
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
Effectively enhances privacy by blocking external views into the enclosure while allowing the door to open and close freely, without the need for additional fasteners or tools, ensuring user privacy without hindering door operation.
Implementation Method 1
On one side of the strip, an adhesive is provided desirably along the length of the side for attachment to a first or second pilaster of an enclosure
Implementation Method 2
The flexible strip preferably nontransparent plastic strip closes off the space between the door and the pilaster when the door is closed to block visual inspection of the inside of the privacy enclosure

AI summary
A privacy enhancer is composed of a first strip preferably rigid and a flexible strip. The first strip has a connector located on one edge. An adhesive is provided along the length of the side for attachment to a first or second pilaster of an enclosure. The enhancer includes a second strip preferably a flexible plastic strip preferably nontransparent having a connector located on an edge of the flexible plastic strip. The two connectors are coupled together. The first strip is then attached to the pilaster by contacting the adhesive side of the strip to the pilaster on the side of the pilaster opposite to the direction of movement of the door. The flexible plastic strip closes off the space between the door and the pilaster when the door is closed.
