Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods are inadequate for safely and efficiently extracting embedded arrowheads from dense materials like tree trunks, posing a risk of injury and difficulty during removal.
Innovation Solution
A manual extraction tool featuring a slide hammer shaft with a receiving portion for the arrowhead and a handle that doubles as a stop for applying force, allowing the slide hammer body to move along the shaft for kinetic removal, while also serving as a latch for apparel or equipment during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to extract embedded arrowheads from dense materials, then the removal process becomes dangerous and difficult, but no effective extraction force can be applied
Solution Approach 1:
The extraction tool is divided into separate functional components: a shaft for attachment to the arrowhead, a slide hammer body for applying force, and a handle for user operation. This segmentation allows each component to perform its specific function efficiently while maintaining overall safety and ease of use.
Solution Approach 2:
The tool employs dynamic impact forces through the slide hammer mechanism, where the hammer body is struck to generate kinetic energy that progressively extracts the embedded arrowhead. This dynamic approach overcomes the static resistance of dense materials without requiring excessive manual force.
2Productivity
If a slide hammer mechanism is used to apply kinetic force, then extraction effectiveness is improved, but device complexity increases
Solution Approach 1:
The tool merges the arrowhead attachment function, force application mechanism, and user handle into a single integrated slide hammer assembly. This combination achieves high extraction efficiency while maintaining relatively simple construction compared to separate specialized tools for each function.
Solution Approach 2:
The slide hammer body serves multiple functions: it attaches to the arrowhead shaft, receives impact forces from the user, and transmits kinetic energy to extract the arrowhead. This multi-functionality improves productivity without proportionally increasing device complexity.
3Volume of moving object
If the tool is designed for compact storage, then portability is improved, but the impact force application area is reduced
Solution Approach 1:
The handle nests within or alongside the slide hammer body when not in use, creating a compact storage configuration. During operation, the handle is extended or positioned to provide adequate leverage and impact force application area, thus reconciling compact storage with effective force application.

Function Achieved in This Case
Enables safe and effective manual extraction of embedded arrowheads from dense materials by applying controlled force, reducing the risk of injury and simplifying the removal process.
Implementation Method 1
by sliding the slide hammer body along the slide hammer shaft for bringing the slide hammer body contact head and the peripheral slide hammer shaft stop into contact, thereby kinetically working out the embedded arrow head

AI summary
An extraction tool for an embedded arrow head works by attaching a slide hammer shaft to the embedded arrow and then working an outer slide hammer body along the shaft to engage cooperating travel stops to kinetically work the arrow head from a dense material in which the arrow is embedded. The extraction tool includes a handle that may be stored parallel to the slide hammer shaft for transport and then disposed to engage the slide hammer body when needed. The slide hammer shaft has an arrow head engagement end with a threaded receiver and a distal stop bolt end that includes for a separate grip and an ancillary attachment.
