Interlocking Privacy Fence Panels for Chain Link Fences

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Chain link fences lack privacy and wind protection due to their apertured construction, with existing slat solutions leaving gaps and exposing the underlying wire, preventing cohesive imagery or texture application and being costly and difficult to install.

Innovation Solution

Elongated panels attached to the outside of chain link fences using rigid or elastic fasteners that engage with the wire, allowing for gap-free installation and expansion joints, enabling complete coverage and aesthetic application without visible wire.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If slats are woven through the chain link fence fabric, then privacy is partially improved, but gaps remain between slats due to knuckles and wire visibility prevents complete privacy

Engineering Contradiction:

Improveprivacy coverageVSAvoidgap-free installation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of weaving slats through the fence fabric from the inside (conventional approach), the patent attaches panels to the outside of the chain link fence. This inversion allows the panels to cover the knuckles and wire completely, eliminating gaps and achieving full privacy coverage without being constrained by the fence's apertured structure

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The privacy solution is divided into multiple separate panels that can be independently installed on the fence. Each panel is a discrete unit that can be attached to the outside of the fence, allowing for modular installation that accommodates fence variations while maintaining continuous coverage when panels are properly joined

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If slats are installed within the chain link mesh fabric, then installation is simplified, but the wire remains visible and prevents cohesive imagery application

Engineering Contradiction:

Improveinstallation simplicityVSAvoidwire visibility and image coherence

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the conventional installation approach by attaching panels to the outside of the fence rather than weaving them through the fabric. This allows the entire wire mesh and knuckles to be completely obscured by the panel surfaces, eliminating wire visibility while maintaining installation simplicity through external attachment mechanisms

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the privacy function from the internal fence structure and places it on the external surface. By removing the dependency on weaving slats through the fabric, the solution separates the privacy function from the fence's apertured structure, allowing for continuous surfaces that can support cohesive imagery and textures

Inventive Principle:

Principle #2Taking out (Extraction)

3Strength

If panels are rigidly fixed to prevent movement, then connection strength is improved, but thermal expansion and contraction causes buckling and displacement

Engineering Contradiction:

Improvepanel connection strengthVSAvoidpanel alignment under thermal loads

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

The patent introduces dynamic elements into the panel connection system through expansion joints that allow panels to move relative to each other. These joints maintain strong connections while accommodating thermal expansion and contraction, preventing buckling and displacement by allowing controlled movement rather than rigid fixation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent explicitly accounts for thermal expansion effects by designing expansion joints between panels. These joints are specifically engineered to accommodate the dimensional changes that occur with temperature variations, allowing the panel system to expand and contract without compromising structural integrity or alignment

Inventive Principle:

Principle #37Thermal expansion

4Reliability

If multiple fasteners are used to secure panels, then attachment reliability is improved, but installation complexity and time increase

Engineering Contradiction:

Improvepanel attachment reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple fastening functions into integrated attachment mechanisms that secure panels to the fence and join panels to each other in fewer steps. By merging the attachment and joining operations into unified fastening systems, the solution maintains reliable securing while reducing the number of separate fasteners needed and simplifying the installation process

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An interlocking plastic fence panel system is described herein that improves the appearance, provides privacy and acts as a wind screen for preexisting chain link fencing. The complementary edges of the panels allow two adjacent panels to be positively joined such that displacement of the panels away from one another is prevented. The interlocking panels are attached with fasteners and can positioned vertically, horizontally, diagonally or any varying angel in between. A decorative texture and or printing can be applied to the surface to enhance the appearance. For example, wood grain texture and printed imagery or advertisements.
