Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current fishing weights are cumbersome to change, requiring line cutting, re-tying, and additional tackle, which can lead to missed fishing opportunities and increased costs, while existing quick-attach solutions like fish finders often snag or limit casting range.

Innovation Solution

A quick-attach sliding fishing weight system featuring a sinker body with internal channels and a rotating quick-attach mechanism, allowing easy attachment and detachment without line cutting or re-tying, and reducing the need for additional tackle by enabling quick weight changes without compromising casting range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If standard fishing weights with eyes or crimped designs are used, then the weight can be securely attached to the fishing line, but changing weights requires line cutting, re-tying, or additional tackle which is time-consuming and cumbersome

Engineering Contradiction:

Improveease of weight changeVSAvoidtime for weight change

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The fishing weight is divided into separate components: a body portion and an attachment mechanism that can be independently attached and detached. The body portion contains an internal channel through which the fishing line passes, while the attachment mechanism (such as a snap-fit or magnetic component) can be quickly connected and disconnected from the line without cutting or re-tying

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An intermediary attachment mechanism is introduced between the fishing weight body and the fishing line. This intermediary component (such as a snap-fit connector, magnetic attachment, or quick-release clamp) enables rapid connection and disconnection without requiring direct knot-tying or line cutting, thus resolving the time-consuming weight change process

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If sliding fishing weights with axial passages are used, then the weight can move freely on the line, but the attachment mechanism lacks convenience and is prone to failure points

Engineering Contradiction:

Improvesliding capabilityVSAvoidattachment reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The attachment mechanism incorporates dynamic elements such as spring-loaded clips, movable retaining arms, or flexible sealing components that adapt to the fishing line while maintaining secure engagement. These dynamic features allow the weight to slide freely along the line while the attachment mechanism automatically adjusts to maintain reliable connection without creating failure points

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If quick-attach solutions like fish finders are used, then weight changes become easier, but they often snag or limit casting range

Engineering Contradiction:

Improveease of weight changeVSAvoidsnagging risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The problematic external attachment components (such as protruding snap-fits, clips, or connection elements) are removed or repositioned to a location that does not protrude outward during casting. The attachment mechanism is integrated into the body contour or positioned on the inner surface, eliminating snagging hazards while maintaining quick-attach functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of having the attachment mechanism protrude outward from the weight body (which causes snagging), the design inverts the attachment approach by having the connection elements recessed into or integrated with the body surface. The fishing line engages with internal features rather than external protrusions, eliminating snagging while preserving quick-attach capability

Inventive Principle:

Principle #13The other way round (Inversion)
