Decoy Line Adjuster Spool Mechanism for Water Level Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waterfowl decoys experience displacement due to fluctuating water levels, leading to unrealistic positioning and potential loss, as existing systems require frequent adjustments by cutting and retying lines, which is inconvenient and inefficient.
Innovation Solution
A decoy line adjuster device with a body, flanges, and a locking system that allows for adjustable line length, featuring a spool and locking mechanism to securely attach and adjust the line between the decoy and anchor, enabling easy lengthening or shortening without retying, using a combination of hooks, guide walls, and a fin for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the line length is fixed, then the decoy remains stable in position, but the system cannot adapt to water level changes without cutting and retying
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed line system into a dynamic, adjustable system. The spool mechanism allows the line length to change dynamically in response to water level fluctuations, enabling the decoy to adapt its position without requiring the hunter to physically cut or rety the line. The rotatable spool with locking mechanism provides continuous adjustability while maintaining stability when needed.
Solution Approach 2:
The patent implements self-service through the automatic engagement of the locking mechanism. When the spool is rotated to adjust line length, the teeth on the spool engage with the cleats on the housing wall, automatically locking the spool in place without requiring additional manual intervention. This allows the system to maintain its adjusted position autonomously, freeing the hunter from continuous adjustment tasks.
2Ease of operation
If a spool mechanism is added, then line length adjustment becomes easy, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjusting mechanism into distinct functional components: the spool for line winding, the teeth for engagement, the cleats for locking, and the guide wall for alignment. This modular segmentation allows each component to perform its specific function efficiently, making the overall complex mechanism manageable and maintainable while providing smooth operation.
Solution Approach 2:
The patent uses the guide wall as an intermediary element that facilitates the interaction between the spool and cleats. The guide wall ensures proper alignment and smooth engagement of the teeth with the cleats during spool rotation, reducing friction and preventing misalignment. This intermediary component simplifies the overall interaction between moving and stationary parts, making the mechanism easier to operate despite its complexity.
