Solution Overview

Problem

Existing fence assembly methods require two people to assemble cross members between fence posts, as individuals cannot hold both ends of long cross members in place.

Innovation Solution

A fence assembly tool with an elongate body and adjustable brackets that can be removably coupled to a fence post, allowing a single person to easily assemble or repair fences by holding and securing cross members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If two people assemble cross members between fence posts, then the assembly can be completed, but it requires assistance from others and cannot be done by a single individual

Engineering Contradiction:
Improveease of fence assemblyVSAvoidassembly process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an assembly tool as an intermediary device that enables a single person to hold and position cross members during fence assembly. The tool acts as a mediator between the assembler and the cross member, providing the necessary support and stability without requiring a second person to assist with holding the cross member in place.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The assembly tool allows the fence assembly process to be performed by a single individual without external assistance. The tool enables the assembler to independently hold, position, and secure cross members between fence posts, transforming a task that previously required two people into a self-service operation.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If an individual attempts to hold both ends of long cross members in place, then assembly can be performed alone, but the individual cannot physically manage the long cross member

Engineering Contradiction:
Improveease of cross member handlingVSAvoidassembly efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The assembly tool serves as an intermediary that extends the assembler's physical reach and holding capability. By using the tool to grip and hold the cross member at one end while the other end is positioned against a fence post, the assembler can effectively manage long cross members without needing to physically hold both ends themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If cross members are held securely in place, then trimming and positioning can be performed, but the holding structure must be stable and sturdy

Engineering Contradiction:
Improvecross member positioning precisionVSAvoidholding structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The assembly tool applies local quality by concentrating its holding and positioning capability at a specific location on the cross member. Rather than requiring the entire cross member to be supported or positioned by complex mechanisms, the tool provides localized grip and support at one end, allowing the rest of the cross member to be freely positioned and trimmed with simple adjustments.

Inventive Principle:
Principle #3Local quality

AI summary

A fence assembly tool is provided. The fence assembly tool may be an auxiliary tool that is removably coupled to a first fence post, to assist an individual in assembling fences. Specifically, the fence assembly tool may include an elongate body that includes one or more brackets extending therefrom. Each of the one or more brackets may be adapted to receive a first end of a cross member of a fence assembly. A second opposing end of the cross member may then be coupled to a second fence post while remaining supported at the first end by the assembly tool. This process may be repeated for multiple cross members as needed, thereby allowing a user to assemble or repair a fence without assistance from others.
