Pivoting Bow Hanger for Secure Tree Mounting Without Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bow hangers for retaining a bow while hunting from a tree stand or saddle often require screwing into a tree, which can damage the tree and is inconvenient for quick setup and removal.
Innovation Solution
A hanger with a support member, pivotably coupled standoff, and hanger arm that can pivot relative to the support member between a use position and a stowed position, and a hanger arm that pivots between extended and retracted positions, allowing secure attachment to a tree without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bow hanger is screwed into a tree, then the hanger can be securely attached, but the tree is damaged and setup/removal is inconvenient
Solution Approach 1:
A strap is introduced as an intermediary element between the hanger and the tree. The strap wraps around the tree trunk and secures the hanger without requiring direct attachment to the tree, thus preventing damage while maintaining secure attachment.
Solution Approach 2:
The mechanical screwing system is replaced with a friction-based strap wrapping system. Instead of using threads and fasteners that penetrate or clamp the tree, the strap uses friction and tension to secure the hanger, eliminating the harmful mechanical interaction with the tree.
2Reliability
If a bow hanger is screwed into a tree, then the hanger can be securely attached, but setup and removal are inconvenient
Solution Approach 1:
The strap acts as a mediator that enables quick attachment and detachment. By wrapping the strap around the tree and securing it through a simple mechanism rather than screwing, the setup and removal process becomes much more convenient while maintaining secure attachment.
Solution Approach 2:
The attachment mechanism transitions from a static screwed-in state to a dynamic strap-based system that can be quickly adjusted, attached, and removed. This dynamic approach allows for rapid setup and teardown operations.
3Ease of operation
If the hanger arm is extended to reach the bow, then the bow can be hung, but the hanger occupies more space for storage
Solution Approach 1:
The hanger arm is designed to be movable rather than fixed. It can extend to reach the bow during use and then be retracted to a compact position for storage, transforming the system from a static to a dynamic configuration that adapts to different operational states.
Solution Approach 2:
The hanger is divided into separable components including the movable arm that can be independently positioned. This segmentation allows the arm to be extended when needed and folded back when not in use, reducing the overall storage volume.

AI summary
A hanger includes a support member. A standoff is pivotably coupled to the support member and is operable to pivot relative to the support member between a use position and a stowed position about a standoff pivot axis. A hanger arm is pivotably coupled to the support member and is operable to pivot relative to the support member between an extended position and a retracted position about a hanger arm pivot axis.
