Barbed Hook Removal Probe Mediator Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing hooks with barbs from tissue, such as fish hooks, often cause severe injury to both humans and animals due to the barb's design, which prevents easy removal and can lead to further tissue damage.
Innovation Solution
An apparatus comprising a clamping device and a probe with a tip portion designed to fit between the barb and the point section of the hook, forming a smooth surface that allows for safe removal without further tissue damage, utilizing a forceps or similar clamping mechanism to secure the hook and guide the probe into the wound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook with a barb is used to penetrate tissue, then the hook can be securely anchored in the tissue, but the barb prevents easy removal and causes severe tissue damage when the hook is extracted
Solution Approach 1:
A smooth probe is introduced as an intermediary tool between the barb and the tissue. The probe fits into the space between the barb and point section, creating a smooth surface that allows the hook to be removed without the barb digging into the tissue. This mediator enables safe removal while maintaining the original barb design for secure anchoring.
Solution Approach 2:
The smooth probe is inserted into the wound tract before hook removal to prepare the path. By placing the probe in advance, the tissue is protected from the barb's harmful action during extraction. The probe establishes a safe removal path that prevents tissue damage while allowing the hooked object to be withdrawn.
2Reliability
If the barb is designed to prevent disgorgement of the hook, then the hook remains securely in place, but the same barb causes severe injury to fish during catch and release
Solution Approach 1:
The smooth probe serves as a mediator that interfaces with the barb to enable safe removal. It fits between the barb and point section, creating a protective smooth surface that prevents the barb from injuring the fish tissue during extraction, while the hook's barb design remains intact for secure retention.
Solution Approach 2:
The harmful barb that causes injury during removal is converted into a benefit by using it as a reference point for probe placement. The probe is specifically designed to fit into the space created by the barb's geometry, transforming the barb's harmful digging action into a structured interface that guides safe removal while preserving the barb's anchoring function.
3Ease of operation
If a simple pulling method is used to remove the hook, then the removal process is quick and simple, but the barb digs into the tissue causing traumatic injury
Solution Approach 1:
The smooth probe is a simple tool that maintains ease of operation while preventing tissue trauma. It is inserted into the wound and positioned between the barb and point section, creating a smooth removal path. The hook is then pulled out along this protected path, combining simplicity with tissue safety.
Solution Approach 2:
The probe is inserted and positioned before the actual hook removal action. This preliminary preparation creates a safe extraction path, allowing the subsequent pulling motion to be both simple and safe. The tissue is protected in advance, enabling straightforward removal without complex procedures.
