Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence systems are difficult to assemble and aesthetically unpleasing, often requiring skilled workers and exposing unsightly brackets, or they lack stability due to proportioned connections for expansion and contraction.
Innovation Solution
A fence post system with apertures that allows horizontal rail supports to be inserted and locked in place using wedges, providing stability and aesthetic appeal by eliminating the need for exposed brackets and allowing for expansion and contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If exposed brackets are used to attach horizontal rails to fence posts, then the connection strength is improved, but the aesthetic appearance deteriorates due to unsightly exposed brackets
Solution Approach 1:
The patent extracts the bracket attachment mechanism from the visible exterior and relocates it to the interior of the fence post. Horizontal rail supports are inserted into apertures within the post, and brackets are positioned inside the post to attach rails without being visible from the outside, thus maintaining connection strength while improving aesthetic appearance.
Solution Approach 2:
The patent implements nesting by placing the bracket attachment mechanism inside the fence post structure. The horizontal rail supports are nested within the post aperture, and the brackets are nested within the post interior, creating a hierarchical arrangement where the attachment mechanism is contained within the post while still providing structural support.
2Shape
If inserts are used to connect rails to fence posts, then the aesthetic appearance is improved by eliminating exposed brackets, but the stability deteriorates due to proportioned connections that allow expansion and contraction
Solution Approach 1:
The patent applies dynamics by designing the horizontal rail supports with features that accommodate thermal expansion and contraction while maintaining stable connection. The supports are proportioned to allow controlled movement within the aperture, and locking mechanisms can be engaged to secure the connection when stability is required, providing dynamic adaptability to environmental conditions.
Solution Approach 2:
The patent utilizes parameter changes by designing the rail supports and apertures with specific dimensional relationships that allow for expansion and contraction. The proportioning of the connection elements includes clearance and flexibility parameters that enable the system to adapt to temperature-induced dimensional changes while maintaining aesthetic appearance and connection stability.
3Stability of the object's composition
If traditional bracket attachment methods are used, then the connection stability is improved, but the ease of assembly deteriorates due to complex measurement and installation requirements
Solution Approach 1:
The patent applies preliminary action by pre-configuring the fence post with apertures at predetermined locations and pre-positioning the horizontal rail supports within these apertures. The bracket attachment mechanism is pre-assembled inside the post, eliminating the need for on-site measurements and complex installation procedures, thus improving ease of assembly while maintaining connection stability.
Solution Approach 2:
The patent introduces an intermediary element - the horizontal rail support - that mediates between the rail and the post interior. This support element simplifies the connection process by providing a pre-fabricated interface that fits into the post aperture, reducing the complexity of assembly while ensuring stable connection through the bracket mechanism.
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
The system enables easy assembly of a stable and aesthetically pleasing fence by inserting horizontal rail supports into apertures and using wedges for locking, ensuring stability and hiding unsightly connections.
Implementation Method 1
The horizontal rail supports inserted into the fence post preferably are locked in place with locking devices for additional stability. These locking devices may be wedges.

AI summary
Apparatus and method of assembling a fence system. A fence post comprises an inner structural post and an outer post. The inner structural post includes a base flange for attaching the inner structural post to a surface. A lower insert block is inserted over the inner structural post and in contact with the base flange. The outer post comprises upper and lower apertures. Horizontal rail supports are inserted through the upper and lower apertures. The horizontal rail supports are locked in place by locking devices. Horizontal rails are inserted over the horizontal rail supports to create a fence system.
