Removable Fence Screen Units for Adjustable Height and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence extension devices do not effectively enhance privacy by providing a removable and adjustable solution to increase the height of fences.
Innovation Solution
A fence extension system comprising removably coupled screen units that extend upwardly from fence sections, each comprising a deformable and translucent panel with a unique structural configuration, including channels and receivers, allowing for adjustable height enhancement and improved privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fence extension devices are made permanent and fixed, then structural stability is improved, but adaptability and ease of removal deteriorate
Solution Approach 1:
The fence extension device is divided into multiple independent components: a base section that attaches to the existing fence, intermediate sections that can be stacked, and a cap section. These segmented components are connected through receiving channels and positioning mechanisms, allowing the structure to be assembled and disassembled while maintaining stability during use. The segmentation enables both structural integrity when installed and ease of removal when needed.
2Adaptability or versatility
If fence extension devices are made removable and adjustable, then adaptability is improved, but structural stability deteriorates
Solution Approach 1:
The fence extension device employs a nested structure where intermediate sections fit within receiving channels of the base and cap sections. The positioning mechanisms and locking features create a nested assembly that maintains structural stability when connected, while allowing individual sections to be removed or repositioned. This nesting approach enables adjustable height and configuration without compromising the overall structural integrity during installation.
3Object-affected harmful factors
If screen units are made opaque for privacy, then privacy is improved, but light transmission deteriorates
Solution Approach 1:
The screen units are designed with varying degrees of opacity across different sections and orientations. Some portions use translucent materials that provide privacy while allowing light transmission, while other areas use more opaque materials for enhanced privacy where needed. This local variation in optical properties allows the fence extension to provide privacy protection in critical areas while maintaining adequate light transmission in areas where visibility or illumination is desired.

AI summary
A fence extension system for selectively increasing a height of a fence includes a fence that has a plurality of sections. A plurality of screen units is provided. Each of the screen units is removably coupled to an associated one of the sections. Each of the screen units extends upwardly from the associated section. Thus, each of the screen units enhances privacy of the fence.
