Fishing Pole Elastic Tension Adjustment via Side Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anglers face challenges in dynamically adjusting the tension of the fishing pole elastic while landing a fish, as existing designs do not allow for real-time adjustments, requiring anticipation of fish size before assembly and resulting in a fixed preload.
Innovation Solution
A hollow tubular fishing pole with a side aperture and a stop mechanism to anchor the fishing line, allowing the angler to manually adjust the elastic tension by pulling on the exposed end of the elastic thread, which can be reinforced with a bush to prevent snagging and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the angler uses a conventional fishing pole with fixed elastic preload, then the pole structure is simple and easy to assemble, but the angler cannot dynamically adjust the elastic tension while landing a fish
Solution Approach 1:
The fishing pole is divided into multiple hollow tubular sections that can be assembled in sequence. The side aperture is provided in a specific section to allow elastic access, while other sections maintain structural integrity. This segmentation enables the adjustment function without compromising the overall pole strength.
Solution Approach 2:
The elastic thread is extracted from being fully enclosed within the pole and is instead accessible through a side aperture. This allows the angler to grab and adjust the elastic externally while maintaining the hollow tubular structure of the pole for strength and lightweight properties.
2Ease of operation
If the angler anticipates fish size before assembly to set fixed preload, then the pole assembly is quick and simple, but the preload cannot be adjusted when actual fish size differs from expectation
Solution Approach 1:
The side aperture is pre-provided in the pole structure, and the elastic is pre-positioned to be accessible through this aperture. This preliminary arrangement enables immediate adjustment without requiring additional components or complex operations when a fish is hooked.
Solution Approach 2:
The angler can directly grab and adjust the elastic thread through the side aperture without requiring tools or assistance. The elastic itself serves as both the functional element and the adjustment mechanism, allowing self-service adjustment during fish landing.
3Adaptability or versatility
If the elastic is fully enclosed within the hollow pole, then the pole maintains structural integrity and lightweight properties, but the angler cannot access the elastic for tension adjustment
Solution Approach 1:
The side aperture is provided in a specific location on the pole rather than throughout. This local modification allows elastic access at the required position while maintaining the structural integrity and lightweight properties of the remaining pole structure. The aperture is strategically placed to minimize impact on overall strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables dynamic adjustment of elastic tension during fish landing, allowing for effective handling of both small and large fish by varying the preload of the elastic thread, enhancing the angler's control and flexibility.
Implementation Method 1
an elastic fishing line at least a portion of which is elastically extendable... which undergoes significant elastic extension compared to the line to which it is attached, so as to provide a shock absorbing effect
Implementation Method 2
carry a stop means to anchor an end portion of the fishing line against passage through said side aperture

AI summary
A fishing pole (10n...101), is provided with a side aperture (18) through which the rear end of a fishing elastic (14) is passed to terminate in an externally accessible knot (20). To increase tension in the elastic an angler may grab the knot and draw out line thereby to increased tension and reduce the effective elasticity of the fishing elastic.
