Spring-Loaded Fishing Bait Dispenser with Adjustable Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attractant dispensers for fishing are limited to bottom fishing due to their weight and design, and they often become unusable once the scent attractants are fully released, lacking versatility for different fishing types and ease of use.
Innovation Solution
A lightweight attractant dispenser composed of a plastic cylinder with a weight element at the bottom, featuring a sponge absorbent material and a spring-loaded carriage mechanism that allows for adjustable attractant distribution and easy cleaning, preventing attractant loss during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a weight element made of lead is used for stabilization, then the attractant dispenser can sink to the bottom for bottom fishing, but it cannot be used for other types of fishing that require floating or mid-water positioning
Solution Approach 1:
The patent applies the dynamics principle by making the weight element adjustable rather than fixed. The weight element can be positioned at different locations along the attractant dispenser body or removed entirely, allowing the device to transition between sinking (bottom fishing) and floating/mid-water positioning (other fishing types). This dynamic adjustment capability resolves the contradiction by enabling the same device to adapt to different fishing scenarios.
2Duration of action of moving object
If the attractant is incorporated directly into the plastic body during production, then the scent is gradually released into the water, but the bait becomes unusable after the scent is completely released
Solution Approach 1:
The patent applies segmentation by separating the attractant reservoir from the bait body. The attractant is stored in a removable cartridge or insert rather than being permanently incorporated into the plastic body. This allows the attractant cartridge to be replaced independently, enabling the bait body to be reused with different attractant cartridges, thus resolving the contradiction between duration of action and reusability.
Solution Approach 2:
The patent applies the discarding and recovering principle by designing the attractant cartridge as a disposable component that can be easily removed and replaced. The main bait body is recovered and reused, while only the depleted attractant cartridge is discarded. This resolves the contradiction by extending the overall usability of the bait system while allowing continuous attractant supply.
3Ease of operation
If holes are provided on the outer edge of the cylinder for water flow, then water can flow into the interior to fill the absorbent material with attractant, but the attractant may be lost through the holes during casting
Solution Approach 1:
The patent applies preliminary action by providing a cap or cover that can be placed over the holes on the outer edge of the cylinder before casting. This preliminary protective action prevents attractant loss during casting while allowing water flow and attractant filling when the holes are open. The cap is easily installed and removed, resolving the contradiction between ease of filling and prevention of attractant loss.
4Adaptability or versatility
If the attractant dispenser is mounted on a spacer in front of the leader, then it becomes independent of other parts and cannot become tangled, but it requires additional mounting components
Solution Approach 1:
The patent applies the merging principle by integrating the mounting function directly into the attractant dispenser body. The dispenser is designed with built-in attachment features such as clips, hooks, or attachment points that allow it to be mounted on the fishing rod or leader without requiring separate spacer components. This integration resolves the contradiction by achieving independence and non-tangling properties while minimizing additional components.
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 versatile fishing techniques beyond bottom fishing, maintains attractant effectiveness, and facilitates easy cleaning and maintenance, ensuring consistent performance across various fishing methods.
Implementation Method 1
The absorbent material is characterized by the fact that it is a sponge. Depending on the sponge material used, the absorption and release speed of the attractant can be influenced.
Implementation Method 2
A spring rests on the hollow pin of the slide. The sponge for absorbing the attractant is located around this spring. If you pull on this ball, you pull the hollow pin and with it the entire slide downwards. This compresses the sponge. If you release the ball, the sponge expands again and returns to its original position.

AI summary
The invention relates to an attractant dispenser (1) for angling and fishing. It is formed from a cylinder (2) and a slide (3) and with an absorbent material (4), which may in particular be designed as a sponge, that is firmly bonded to the top of the slide and the bottom (6) of the cylinder. The cylinder may have a weight element (7) at its bottom and bores (8) on its outer edge, and an eyelet (11) at its upper end (10) for mounting on a spacer (9) in front of a leader (9a).
