Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile tree climbing sticks face challenges in reducing both weight and package size while maintaining ease of use and transport.
Innovation Solution
A telescoping tree climbing stick assembly with at least two sections that can extend for climbing and collapse for compact transport, featuring a releasable lock and a tether for added security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If climbing sticks are made shorter for easier transport, then package size and portability are improved, but climbing height and utility are reduced
Solution Approach 1:
The patent applies nesting by placing one telescoping section inside another, allowing the climbing stick to collapse into a compact form for transport while maintaining full extended length for climbing. The inner section slides within the outer section, enabling the stick to nest to a fraction of its extended size.
Solution Approach 2:
The patent implements dynamics by making the climbing stick telescoping rather than fixed-length. The stick can dynamically change its length between a short collapsed state for portability and a long extended state for climbing, allowing it to adapt to different transport and usage requirements.
2Volume of moving object
If climbing sticks are made collapsible to reduce package size, then portability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the climbing stick into multiple telescoping sections that can slide relative to each other. This segmentation allows the stick to collapse into a compact form while using simple cylindrical sections that minimize structural complexity compared to more elaborate folding mechanisms.

AI summary
A tree climbing stick assembly includes a post supporting at least one step and having at least two sections which telescope relative to one another for longitudinal movement between an extended position and a collapsed position. The assembly is mountable to a tree to be climbed such as by a rope. A releasable lock secures the post sections releasably in the extended position for use when climbing. The lock can be released and the sections telescopically collapsed when not in use for ease of transport in a compact state. A tether is secured to each of the sections and prevents longitudinal separation of the sections independent of the releasable lock, such that if the sections were to somehow extend past the extended and locked position, the tether secures holds the sections in telescopic engagement and keeps them from completely separating as a secondary retention system.
