Solution Overview

Problem

Existing garden wire panel fences are tedious to assemble and prone to slat displacement due to wind, as the current fixing methods are not sufficient to withstand strong winds.

Innovation Solution

A fence system with a fixing element that includes a suspension and a support foot with a tensioning element, made with a curved part, which can be inserted into the slat's internal space, providing a secure and adjustable attachment to transverse wires, allowing for easier assembly and enhanced wind resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the current fixing method with hook-shaped fastening elements and lips is used, then the fence can be assembled, but the assembly process is tedious and requires additional time and dexterity

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The fixing element is divided into distinct functional segments: a suspension portion that attaches to the transverse wire and a support portion that secures the slat. This segmentation allows each part to be optimized independently and simplifies the overall assembly process by separating the attachment functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing element is designed to be self-aligning and self-securing. The support portion with its curved part automatically engages with the slat's internal space, and the tensioning element provides automatic tensioning without requiring precise manual adjustment or additional fastening steps.

Inventive Principle:
Principle #25Self-service

2Reliability

If the current fixing method with transverse profiles is used, then the fence structure is simple, but the slats are not sufficient to withstand strong winds and may be carried away

Engineering Contradiction:
Improvewind resistanceVSAvoidfixing element complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tensioning element is pre-configured with the curved part that engages with the slat's internal space before the slat is fully installed. This preliminary engagement ensures that the slat is securely held from the beginning, preventing wind-induced displacement without requiring complex additional anchoring mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support portion incorporates a curved part that complements the internal space geometry of the slat. This curved design provides optimal contact surfaces that distribute wind loads more effectively compared to flat or angular connections, enhancing the overall wind resistance of the fence structure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Stability of the object's composition

If the tensioning element with curved part is inserted into the slat's internal space, then slat displacement and vibration due to wind is prevented, but the fixing element requires more complex design

Engineering Contradiction:
Improveslat stabilityVSAvoidfixing element design complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The suspension and support portions are merged into a single integrated fixing element. This combination eliminates the need for separate attachment components and reduces the overall number of parts, thereby simplifying the design while maintaining the stability-providing features of the curved engagement and tensioning mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fixing element is designed to perform multiple functions simultaneously: the suspension portion attaches to the transverse wire, the support portion secures the slat, and the tensioning element provides both positioning and stabilization. This multi-functionality reduces the need for additional specialized components, simplifying the overall design while ensuring slat stability against wind loads.

Inventive Principle:
Principle #6Universality (Multi-functionality)
