Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple magnets are coupled together to adjust sinker weight, then weight adjustment flexibility is improved, but outer surface smoothness deteriorates
Solution Approach 1:
The sinker is divided into a main body portion and multiple separate weight portions that can be independently attached or detached. This segmentation allows flexible weight adjustment by adding or removing weight portions while keeping the main body smooth and streamlined for hydrodynamic performance.
Solution Approach 2:
A connection structure acts as an intermediary between the main body and weight portions, using magnetic coupling to join them. This intermediary mechanism enables easy attachment and detachment of weight portions without compromising the smooth outer surface of the main body, resolving the contradiction between adjustability and surface quality.
2Adaptability or versatility
If multiple magnets are coupled together to form sinker assembly, then weight adjustment capability is improved, but structural complexity increases
Solution Approach 1:
The connection structure utilizes magnetic coupling forces to automatically attach and detach weight portions without requiring external tools or complex mechanical fastening mechanisms. This self-service approach simplifies the overall structure while maintaining weight adjustment capability, as the magnetic fields themselves perform the coupling function.
3Adaptability or versatility
If sinker structure is expanded to match fishing types, then functional versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The main body is designed with a universal connection structure that can accommodate different types of weight portions and auxiliary members for various fishing conditions. This universal design allows a single base structure to serve multiple functions across different fishing scenarios, reducing the need for multiple specialized sinker designs and simplifying manufacturing.

AI summary
A fishing sinker device is configured to extend based on a coupling force of magnets. The fishing sinker device includes a main member formed at least partially of a magnetic material and including a lower coupling part, a sub member formed to be engaged with the main member with the same diameter, and configured to maintain a coupling force therebetween by a permanent magnet accommodated in an upper coupling part thereof, and an adjustment member added to at least one of the main member and the sub member to adjust a function thereof. Accordingly, the sinker which allows the bait to reach the desired depth during fishing have effects of increasing the usability since the shape and function of the sinker can be easily expanded matching with the type of fishing while maintaining the desired length and weight of the sinker by a magnetic force.
