Solution Overview

Problem

Existing string attachment methods, such as beads with holes, require removing existing beads to add new ones, which is inconvenient and may damage the string due to knots or obstructions, limiting the ability to add beads of different colors without disrupting the existing arrangement.

Innovation Solution

A fishing line stop design featuring a lid and main body with a channel and offset, allowing the string to be cradled and secured without threading through a hole, enabling easy attachment and balance of beads on the string while maintaining a smooth surface for snag-free use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bead with a hole is used to attach to a string, then the bead can be affixed to the string, but existing beads must be removed to add new ones and knots or obstructions on the string prevent threading through the hole

Engineering Contradiction:

Improveability to add beads without removing existing onesVSAvoidconvenience of attaching beads to string

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bead is divided into two separate components: a main body that contains the string and a lid that closes over the top. This segmentation allows the string to be threaded through the main body first, then the lid is attached separately, enabling beads to be added without removing existing ones from the string.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lid nests over the main body to form a complete bead assembly. The lid is designed to fit over the main body and secure the string in place, creating a nested structure that allows easy attachment to the string without requiring the string end to be free of obstructions.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the string is threaded through a hole in the bead, then the bead can be affixed to the string, but the string end must be free of knots or restrictions

Engineering Contradiction:

Improvesecure attachment of bead to stringVSAvoidflexibility to use strings with knots or obstructions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

Instead of threading the string through a hole in the bead as one piece, the invention inverts the process by first placing the string through the main body and then closing it with a separate lid. This allows the string to have knots or obstructions at its end while still achieving secure attachment.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If a channel without offset is used, then the string can pass through easily, but the bead cannot be balanced properly on the string

Engineering Contradiction:

Improveease of string passage through beadVSAvoidbalance of bead on string

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

An offset is introduced into the channel, creating an asymmetric structure where the channel is positioned at an angle rather than centered. This asymmetry allows the bead to be balanced properly on the string while still enabling the string to pass through easily during the attachment process.

Inventive Principle:

Principle #4Asymmetry

AI summary

Fishing line stops are disclosed. Fishing line stops illustratively include a lid and a main body. The lid has inner and outer walls. The lid outer wall forms a portion of an outer surface of the fishing line stop. The lid inner wall has first and second surfaces. The lid inner wall first and second surfaces are separated from each other by a lid offset that runs perpendicular to a central longitudinal axis. The main body has inner and outer walls. The main body inner wall forms another portion of the outer surface of the fishing line stop. The main body inner wall has first and second surfaces. The main body inner wall first and second surfaces are separated from each other by a main body offset that runs perpendicular to the central longitudinal axis.
