Solution Overview

Problem

Existing devices for anchoring platforms or structural components in trees, such as treehouse screws, can damage trees and fail under load due to their diameter being reduced, necessitating an improved anchoring solution.

Innovation Solution

A sealing element with a profiled surface, such as ribbed or wavy, is used to create a device with an overgrowth body that integrates into the tree's structure, promoting overgrowth and increased pull-out resistance, and a bolt with a compression mechanism to secure the anchoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the diameter of tree screws is reduced, then the damage to trees is minimized, but the load-bearing capacity decreases

Engineering Contradiction:
Improvetree damageVSAvoidload-bearing capacity
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The anchoring device is divided into multiple functional segments: a bolt portion for initial anchoring, an overgrowth element with profiled surface for biological integration, and a platform connection element. This segmentation allows each component to perform its specific function optimally while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The overgrowth element acts as an intermediary between the bolt and the tree. It features a profiled surface that promotes tree overgrowth, creating a biological bond that transfers loads from the bolt to the surrounding wood tissue, thereby increasing load-bearing capacity without requiring larger screw diameters.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If treehouse screws are used for anchoring, then platforms can be secured in trees, but the screws can damage trees and fail under load

Engineering Contradiction:
Improveanchoring capabilityVSAvoidanchoring reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The device incorporates an overgrowth element with a profiled surface that is designed to promote preliminary tree overgrowth before full load application. This preliminary biological action creates a stronger bond between the anchoring device and the tree, improving reliability while maintaining ease of installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The anchoring system combines synthetic materials (bolt, overgrowth element) with natural biological materials (tree tissue). The composite structure leverages the strength and durability of synthetic materials while utilizing the tree's own growth and healing processes to enhance anchoring reliability and reduce damage.

Inventive Principle:
Principle #40Composite materials
