Deformable Insert Fence Post Mount for Shallow Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence post installation methods require deep burial, which can cause difficulties due to interference with underground utilities and damage, and result in frequent replacement and repair due to stress from weather and animal impact.
Innovation Solution
A post mount system that includes a body and insert, where the body is driven into the substrate and the insert is deformed to anchor the post mount, allowing for shallower installation depth with equivalent strength, using a tool with a moveable collar to drive the insert and splay it outwardly, and a post assembly with attachment points for gates and fences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fence posts are buried deeply into the ground to provide required strength, then the strength and stability of the fence post is improved, but the difficulty of installation increases due to interference with underground utilities and damage risks
Solution Approach 1:
The fence post system is divided into two main segments: an above-ground post component and a separate below-ground mount component. The mount is driven into the substrate to a shallower depth than traditional single-piece posts, reducing interference with utilities. The post is then attached to the mount, combining the benefits of shallow installation with adequate above-ground strength.
Solution Approach 2:
The invention transitions from a vertical single-piece post design to a two-component system where the mount extends horizontally outward from the substrate surface. This dimensional change allows the anchor points to spread laterally rather than requiring deeper vertical burial, achieving stability through lateral distribution of force.
2Stability of the object's composition
If fence posts are made as single piece items buried deeply, then the structural integrity is improved, but the frequency of replacement and repair increases due to stress from weather and animal impact
Solution Approach 1:
By segmenting the fence post into separate above-ground and below-ground components, the invention allows the mount buried in the substrate to absorb stresses from weather and animal impact, protecting the above-ground post from damage. The mount acts as a sacrificial element that can remain stable while the post may be replaced if damaged.
Solution Approach 2:
The mount component provides beforehand cushioning by absorbing and distributing mechanical stresses from weather events and animal impacts before they can transfer to the above-ground post. The deformable insert in the mount acts as a shock-absorbing element that protects the overall structure.
3Strength
If fence posts require deep burial installation, then the anchoring strength is improved, but the complexity of installation process increases due to digging and filling operations
Solution Approach 1:
The installation process is segmented into two simpler steps: first driving the mount component into the substrate to a shallow depth, then attaching the post to the mount. This eliminates the complex process of digging deep holes and filling them with concrete or other materials, while still achieving adequate anchoring strength through the deformable insert mechanism.
Solution Approach 2:
The deformable insert in the mount automatically anchors itself to the substrate through deformation upon driving, eliminating the need for additional materials like concrete or mortar. The insert's own material properties provide the anchoring function, simplifying the installation process to just driving and attaching.
4Strength
If traditional fence post installation methods are used, then the structural strength is maintained, but the time required for installation and repair increases
Solution Approach 1:
The segmented design allows for rapid installation by first driving the pre-fabricated mount into the substrate (a quick operation requiring minimal preparation), then simply attaching the post to the mount. Repair time is reduced because damaged posts can be quickly removed and replaced without disturbing the mounted base, which remains in place providing continuous structural support.
Solution Approach 2:
The mount component is prepared in advance and can be driven into the substrate before the post is attached. This preliminary action allows the anchoring mechanism to be established first, creating a stable base that speeds up the overall installation process. The separable design also allows for quick replacement of posts without re-installing the mount.
