Adjustable Gravity Centre Wobbler for Diving Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wobblers lack the ability to dynamically adjust their movement characteristics and diving depth on the fishing location, leading to the need for multiple wobblers and increased costs, and existing weight adjustments fail to significantly impact the wobbly movement or balance properties.
Innovation Solution
A wobbler with an adjustable gravity centre location, allowing the fisher to change the height of the gravity centre relative to the central axis by drilling a hole and using a sleeve with a threaded additional weight, enabling adjustment of balance properties and diving depth through varying the mass and position of the weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional weights are placed under the wobbler casing to adjust floating properties, then the floating properties and diving depth are improved, but the stability of the wobbler increases which reduces the wobbly movement important for fishing
Solution Approach 1:
The patent moves the additional weight from under the casing to inside the casing, changing the spatial dimension of weight placement. This allows the weight to be positioned along the longitudinal axis without being under the centerline, thus adjusting floating properties while preserving wobbly movement characteristics
2Length of moving object
If additional weights are placed under the centerline of the casing to adjust floating properties, then the diving depth is improved, but the stability of the wobbler increases which reduces the oscillating movement
Solution Approach 1:
The patent positions the additional weight inside the casing along the longitudinal axis rather than under the centerline, utilizing the internal dimensional space to achieve diving depth adjustment without compromising oscillating movement through excessive stability
3Adaptability or versatility
If a fisher takes multiple wobblers with different characteristics to fishing trips to adapt to different conditions, then the adaptability to fishing conditions is improved, but the quantity of equipment and purchase expenses increase
Solution Approach 1:
The patent makes the wobbler dynamically adjustable by allowing the fisher to change the mass and longitudinal position of the additional weight inside the casing, enabling a single wobbler to adapt to different fishing conditions that previously required multiple specialized wobblers
Solution Approach 2:
The patent creates a universal wobbler design where a single device can perform multiple functions by adjusting the additional weight configuration, replacing the need for multiple specialized wobblers for different fishing scenarios
4Reliability
If the mass of the additional weight is changed to adjust floating properties, then the floating properties are improved, but the impact on balance properties and wobbly movement remains limited
Solution Approach 1:
The patent adds the longitudinal position dimension for weight placement inside the casing, allowing adjustment of both mass and position to comprehensively control floating properties and balance characteristics, whereas previous solutions only allowed mass variation at fixed locations
