Climbing Stick Tree-Engaging Structure for Quiet Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable treestand systems are either too heavy and bulky due to the use of cast metals, prone to catastrophic failure, and noisy, while also lacking stability when attached to a tree, which can lead to safety issues and alerting game during hunting.
Innovation Solution
A portable treestand system manufactured using a monolithic platform made from strengthened metal, such as aluminum alloy, with structural supports and tree engaging structures formed by CNC machining, which reduces weight, enhances stability, and minimizes noise through the use of oil-infused nylon washers and strategically placed weight reduction apertures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If climbing sticks and platforms are made from lightweight metal tubes with welded steps and tree engaging features, then the system becomes lighter and more portable, but it generates undesirable noise from flexing materials and poor welds
Solution Approach 1:
The climbing stick is divided into modular components: a tubular frame, separately attached steps with anti-slip surfaces, and distinct tree engaging features. This segmentation allows each component to be optimized independently - the tubular frame provides lightweight structure while the separately attached features eliminate noise from welding and reduce flexing noise through proper connection methods.
Solution Approach 2:
The invention uses composite construction combining tubular metal frames with anti-slip step surfaces and noise-reducing tree engaging features. The steps incorporate anti-slip coatings or textured surfaces that reduce noise while maintaining grip, and the tree engaging features use materials that minimize noise during attachment and loading.
2Object-generated harmful factors
If cast metal platforms are used to minimize weld points, then noise from welding is reduced, but the platforms become brittle and prone to catastrophic failure
Solution Approach 1:
The platform is segmented into a base platform and separately attached steps rather than being a single cast metal piece. This allows the use of stronger, more ductile materials for the main platform structure while adding steps as separate components with anti-slip surfaces, eliminating the need for brittle cast metal construction.
Solution Approach 2:
The invention changes the material parameters from brittle cast metal to ductile tubular metal construction. The tubular frames provide inherent ductility and resistance to catastrophic failure, while the anti-slip step surfaces are added as separate functional elements that can be attached without welding, thus avoiding noise issues.
3Reliability
If the platform and seat are made larger to compensate for brittle cast metal properties, then safety is improved, but the system becomes heavier and bulkier
Solution Approach 1:
The invention changes the fundamental material parameters from brittle cast metal to ductile tubular metal construction. This allows for a more efficient use of material - the tubular frames provide high strength-to-weight ratio and inherent ductility, eliminating the need to increase platform size to compensate for brittleness. The anti-slip step surfaces are added as thin, lightweight components.
Solution Approach 2:
The platform uses composite construction with tubular metal frames providing structural strength and ductility, combined with anti-slip step surfaces that add functionality without significant weight. This composite approach achieves both safety through material selection and lightweight design through efficient structural form.
4Weight of moving object
If the treestand system is made more compact and lightweight for portability, then ease of transport is improved, but stability when attached to the tree deteriorates
Solution Approach 1:
The tree engaging features are segmented as separate components attached to the tubular frame rather than integrated welds. This allows for larger, more robust tree engaging features that provide stability when mounted, while the overall frame remains lightweight and portable. The modular attachment allows optimization of each component for its specific function.
Solution Approach 2:
The invention changes the construction parameters to use tubular metal frames with optimized wall thickness and geometry that provide high strength-to-weight ratio. The tree engaging features use materials and designs that maximize grip and stability when attached to trees, while the overall system remains compact and lightweight for portability.
