Solution Overview

Problem

Existing fishing bags do not effectively prevent damage to multiple fishing rods during storage and movement, as they often collide with each other.

Innovation Solution

A fishing bag design featuring a first body and a second body that are hingedly opened and closed, with detachable fishing rod handle and guide pouches that are coupled using magnetic forces and coupling rings, allowing for secure storage and easy access to fishing rods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If multiple fishing rods are stored together in a space other than the auxiliary storage room, then the storage space is utilized efficiently, but the fishing rods may collide with each other and be damaged during movement of the bag

Engineering Contradiction:
Improvestorage space utilizationVSAvoidfishing rod damage prevention
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent divides the storage space into separate compartments: an auxiliary storage room for rod tips and individual pouches for rod handles and guides. This segmentation prevents different parts of multiple rods from colliding with each other while maintaining efficient space utilization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested storage structure where the auxiliary storage room is integrated inside the main bag body, and pouches for rod handles and guides are placed within the bag. This nesting approach allows multiple rods to be stored together without collision by organizing them in hierarchical compartments.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the fishing bag is opened fully to take out the fishing rod, then the fishing rod can be accessed, but the user has to lay the fishing bag on flat ground and fully open the locking device which is inconvenient

Engineering Contradiction:
Improvefishing rod accessibilityVSAvoidopening and closing operation
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the bag into a first body and a second body that can be opened independently via hinged connections. This allows users to open only the necessary compartment to access the fishing rod without fully opening the entire bag, eliminating the need to lay the bag on flat ground.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces magnetic coupling mechanisms as intermediaries between the first and second bodies, allowing them to be coupled and uncoupled easily without complex locking devices. This simplifies the opening and closing operation while maintaining secure connection during transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a separate auxiliary storage room is installed inside the bag for rod tips, then the rod tip storage is improved, but the structure becomes more complex

Engineering Contradiction:
Improverod tip storage convenienceVSAvoidbag structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the auxiliary storage room for rod tips with the main bag body structure, integrating it as a built-in compartment rather than a separate attached structure. This combining approach provides convenient rod tip storage while avoiding the complexity of separate auxiliary structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The auxiliary storage room serves multiple functions: storing rod tips, organizing rod components, and providing structural support. This multi-functionality reduces the need for additional separate structures, simplifying the overall bag design while maintaining storage convenience.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

Proposed is a fishing bag for inhibiting a plurality of fishing rods from being broken due to collisions therebetween. The fishing bag includes a fishing bag divided into a first body and a second body, that have accommodation spaces in which a fishing rod handle and a fishing rod guide are inserted, respectively, and are hingedly opened and closed, a fishing rod handle pouch detachably provided in the first body and storing the fishing rod handle therein, and a fishing rod guide pouch detachably provided in the second body and storing the fishing rod guide therein. The fishing rod handle pouch and the fishing rod guide pouch can be easily opened and closed with one hand through the elasticity of an opening/closing member, so the convenience of use is provided.
