Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing surfcasting bags lack customizable and elegant solutions for interchanging accessories, particularly in wet conditions, and fail to provide secure attachment in harsh weather and water environments.

Innovation Solution

A surfcasting bag system with interchangeable storage units that utilize a tandem fastener system, including a twisting lock and a secondary safety latching lock, allowing seamless attachment and detachment between a main bag, waist belt loop, and shoulder strap, using durable materials resistant to saltwater and snagging, and incorporating adjustable shoulder straps and waterproof lure tubes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If metal or plastic carabiners are used for detachable storage options, then storage units can be detached and reattached, but the operation becomes difficult with wet or gloved hands and requires precise dexterity

Engineering Contradiction:

Improveinterchangeability of storage unitsVSAvoiddifficulty of attaching/detaching with wet hands

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional carabiner mechanical system (requiring precise finger manipulation of small metal components) with a twist-lock mechanical system featuring large, glove-friendly knobs that can be operated with wet hands or gloves. The twist-lock mechanism uses rotational motion rather than precise gripping, substituting the fine-motor-skill-based operation with a coarse-motor-skill-based operation that is much easier to perform in wet conditions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If permanent and integral storage options are used, then storage units are securely attached, but the ability to customize and interchange accessories is limited

Engineering Contradiction:

Improvesecure attachment of storage unitsVSAvoidcustomizability of storage configuration

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent divides the storage system into separate, modular components (storage units) that can be independently attached or detached from the main bag via the twist-lock mechanism. Each storage unit is a discrete module that can be selectively attached based on the user's specific needs for a given fishing trip, enabling customization while maintaining secure attachment through the reliable twist-lock and safety latch system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transforms the static, permanent attachment system into a dynamic, reconfigurable system. The twist-lock mechanism allows storage units to be easily attached and detached, enabling the system to adapt its configuration based on changing user needs, weather conditions, or fishing scenarios, while the safety latch ensures secure attachment when units are in use.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If traditional fasteners are used, then attachment can be achieved, but the fasteners may accidentally loosen in high winds or rough water conditions

Engineering Contradiction:

Improvesimplicity of attachment mechanismVSAvoidsecurity against accidental loosening

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent incorporates a safety latch mechanism that acts as a backup security feature before accidental loosening can occur. The safety latch is designed to engage automatically or easily after the twist-lock is engaged, providing a redundant locking mechanism that prevents accidental loosening due to wind, water, or vibration, while not significantly complicating the attachment process.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If multiple storage options are provided, then customization is possible, but the device complexity and number of components increases

Engineering Contradiction:

Improvenumber of storage configurationsVSAvoidnumber of fastening components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the twist-lock mechanism and storage units with standardized interfaces that allow the same attachment system to be used across multiple different storage unit types and configurations. This universal interface design enables high customization potential without proportionally increasing complexity, as the same basic mechanism handles all attachment operations regardless of which specific storage units are being attached.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

I disclose here a system of interchangeable surfcasting bags and surfcasting equipment storage units. A variety of storage units are selectively secured to a base bag, waist belt or shoulder strap by a standardized tandem locking means. An upper lock is engaged with a simple twist of even a wet, gloved hand. A lower, secondary, lower lock latches in place and ensures the storage unit remains attached to its base in the harshest conditions. Storage units have male twisting locks and latches. Base bags, waist belts or shoulder straps have corresponding female twisting locks and latches. A distancing tool template is provided to ensure consistent and standard distance between upper and lower lock and latch components on all system pieces at all times.
