Solution Overview

Problem

Anglers using side-rigged outrigger spars face challenges with halyard creep and the manual operation of latching and unlatching the fishing-line release clip, which is difficult due to the distance from the boat to the outrigger spar tip, making it hard to manage the pulley-type endless halyard effectively.

Innovation Solution

A remotely operable latch system comprising a dock half and a traveller half, connected by a pulley-type endless halyard, allows for manual operation from the boat to latch and unlatch the fishing-line release clip, using a stylus and heart-shaped groove mechanism to secure and release the traveller, preventing halyard creep and facilitating easy retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a manual latch mechanism is used for the fishing-line release clip, then the clip can be secured at the outrigger spar tip, but it becomes difficult to operate from the boat due to the distance and complexity of manual latching

Engineering Contradiction:
Improveease of latching operationVSAvoidcomplexity of latch mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The latch mechanism is divided into two separate components: a dock half fixed at the outrigger spar tip and a traveller half that moves with the fishing-line release clip. This segmentation allows the latch to be operated remotely from the boat while maintaining secure connection at the spar tip, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The endless halyard acts as an intermediary element connecting the traveller half to the dock half. By pulling the halyard, the operator can remotely control the latching and unlatching actions without directly manipulating the latch mechanism at the distant spar tip, thereby improving ease of operation while keeping the latch mechanism itself simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the fishing-line release clip is manually latched at the outrigger spar tip, then it remains secured, but halyard creep causes the clip to move away from the spar tip over time

Engineering Contradiction:
Improvesecurity of clipped positionVSAvoidhalyard creep
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The latch mechanism provides preliminary anti-action against halyard creep by creating a mechanical interlock between the traveller half and dock half. When latched, the stylus in the heart-shaped groove prevents the traveller from moving outward, counteracting the creep force before it can cause the clip to detach or move away from the spar tip.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The patent replaces a simple mechanical attachment with a stylus-and-groove locking mechanism. The stylus engages with the heart-shaped groove to create a positive mechanical stop that prevents outward movement, effectively substituting a passive mechanical connection with an active locking system that resists halyard creep.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the outrigger spar is extended far from the boat for trolling, then fishing coverage is improved, but the distance makes manual management of the halyard and release clip difficult

Engineering Contradiction:
Improvefishing coverage areaVSAvoidease of halyard management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The endless halyard serves as a flexible intermediary that transmits force from the boat to the traveller half at the distant outrigger spar tip. This allows the operator to manage the halyard from the boat while the traveller half performs the latching function at the remote spar tip, maintaining ease of operation despite the extended distance.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

By segmenting the latch system into fixed dock half and movable traveller half, the patent enables independent operation at the remote spar tip while maintaining control from the boat. The segmentation allows the halyard to be managed from the boat while the latching action occurs automatically at the distant location, preserving ease of operation.

Inventive Principle:
Principle #1Segmentation

AI summary

A remotely operable latch for a pulley-type endless halyard has a traveller, a tubular hollow dock for receiving and latching onto the traveller, a fishing-line release clip conjoined to the traveller, proximal pulley tackle mounted to a boat, distal pulley tackle conjoined with the dock and mounted to an outrigger spar, and an elongated halyard. The halyard has a distal end connected to the traveller, and a proximal end threaded through the dock, around the distal pulley, and then again around the proximal pulley, and connected to the fishing-line release clip. The traveller has a sidewall formed with a heart-shaped groove and the dock has an inside sidewall provided with an tone arm elongated between a pivotal base and a stylus for tracing the groove in the traveller, wherein the traveller latches in the dock when the stylus is caught in the cleavage of the heart-shaped groove.
