Integrated Safety Cable Sleeve for Two-Piece Tree Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-piece climbing tree stand safety harness systems are cumbersome and prone to disassembly issues, especially in low-light conditions, due to the need to attach and detach a separate flexible belt, which interferes with the tree stand's movement and requires reassembly each time the stand is used.
Innovation Solution
A safety cable is permanently attached to the upper portion of the tree stand within a flexible sleeve, eliminating the need for assembly or disassembly at the hunting site, and is securely positioned using a tubular sleeve and clamping mechanisms to prevent interference during climbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate flexible belt is used to attach the safety harness to the tree stand, then the safety harness can be attached and detached, but the belt interferes with the movement of the two pieces of the tree stand and requires reassembly each time the stand is used
Solution Approach 1:
The patent combines the safety cable attachment directly to the upper tree stand piece, merging the safety harness system with the tree stand structure itself. This eliminates the separate flexible belt and its associated attachment/detachment operations, resolving the contradiction by making the safety system permanently integrated rather than removable.
2Stability of the object's composition
If a stiffening means is added to the flexible belt to prevent interference with tree stand movement, then the belt maintains its position, but the attachment becomes more complex and cumbersome especially in dark conditions
Solution Approach 1:
The patent extracts the stiffening means and complex attachment device from the system entirely. By permanently attaching the safety cable directly to the upper tree stand piece and allowing it to flex naturally within the sleeve, the solution eliminates the need for stiffening components and complex attachment mechanisms, resolving the contradiction by removing the source of complexity.
3Ease of operation
If the safety cable is permanently attached to the upper portion of the tree stand within a flexible sleeve, then the safety cable does not interfere with tree stand movement and requires no assembly, but the cable must remain secured in position
Solution Approach 1:
The patent uses a flexible sleeve to contain and guide the safety cable. The sleeve is flexible enough to allow the cable to move with the tree stand pieces during assembly and operation, yet it maintains the cable's position and prevents it from becoming disassociated. This resolves the contradiction by providing a flexible containment structure that ensures both ease of operation and reliable positioning.

AI summary
A safety system for a two piece tree climbing stand includes a safety cable that is secured to the climbing cable of the tree stand so as not to interfere with the two pieces of the stand as the tree stand is maneuvered up a tree. An elongated resilient sleeve is adapted to surround both the climbing cable and the safety cable so that the safety cable is secured to the tree climbing cable until the sleeve is removed. The safety cable is adapted to be secured to the safety harness worn by the tree climber and to the climbing cable of the tree stand.
