Collapsible Spool Holder Eliminates Line Tension via Eyelet Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing spool holders introduce tension, twists, and kinks in the fishing line during transfer to the reel, and often cause fractures or cracks in the fishing rod due to clamp-type attachments, failing to provide a tension-free and damage-free solution.
Innovation Solution
A collapsible spool holder that hangs from the fishing rod's eyelet, using a triangular design with adjustable tension nuts and a ball-and-socket joint mechanism to secure the spool without applying tension, allowing the spool holder to be easily detachable, transportable, and collapse into a compact form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a clamp-type mechanism is used to attach the spool holder to the fishing rod, then the spool holder is securely attached, but tension is introduced onto the fishing rod that can result in breaks or fractures
Solution Approach 1:
The harmful clamp-type attachment mechanism is completely removed from the system. Instead of attaching to the rod, the spool holder hangs freely from an eyelet on the rod, extracting the source of tension and potential rod damage while maintaining secure attachment during line transfer operations
Solution Approach 2:
An eyelet on the rod serves as an intermediary attachment point that allows the spool holder to hang without creating tension on the rod itself. This intermediary structure enables secure attachment while eliminating the harmful mechanical stress that caused rod fractures
2Strength
If a clamp-type securing structure is used to attach the spool holder, then the holder is securely mounted, but tension is introduced in the fishing line which results in inefficient casting
Solution Approach 1:
The clamp-type securing structure that created harmful tension is removed entirely. The spool holder attaches to an eyelet instead, allowing the fishing line to transfer without tension while maintaining secure holder mounting during the line transfer process
Solution Approach 2:
Instead of securing the holder to the rod with clamps that pull on the line, the holder is inverted to hang freely from an eyelet. This inversion changes the attachment methodology from tension-based to gravity-based suspension, eliminating line tension while maintaining security
3Ease of operation
If the spool holder is designed to be portable and collapsible, then ease of transport is improved, but structural complexity increases
Solution Approach 1:
The spool holder is divided into separate collapsible segments that can be folded together for compact storage and transported easily. This segmentation allows the structure to collapse into a small form factor while maintaining full functionality when deployed
Solution Approach 2:
The spool holder employs dynamic, movable joints that allow the structure to collapse and expand. These dynamic elements enable transitions between a compact transport configuration and a functional deployed configuration, achieving portability without sacrificing structural integrity
