Removable Rod Butt Battery Integration for Electric Reel Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric powered fishing reels face issues with external battery packs that interfere with operation, cause imbalance, and pose safety risks due to dangling cords or added weight, and lack flexibility in reel and battery replacement.
Innovation Solution
A fishing rod assembly with an integral energy source in a removable rod butt assembly, featuring a rechargeable battery cell assembly, power switch, and integrated circuit board, which can be easily detached and replaced, and includes a battery management system for safety and charging, with mating connectors and wiring harnesses for seamless integration with the reel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an external battery pack is used to power the electric reel, then the reel can be powered, but the battery pack adds substantial weight and interferes with rod operation and balance
Solution Approach 1:
The patent integrates the battery pack into the rod butt assembly, merging the power source with the rod structure itself. This eliminates the need for separate external battery packs and resolves the contradiction by incorporating the weight of the battery into the rod's overall structure, thereby maintaining balance while providing power.
Solution Approach 2:
The battery pack is nested within the rod butt assembly, with the battery housing positioned inside the butt structure. This nesting approach allows the battery to be contained within the existing rod structure, minimizing additional weight and interference while maintaining power supply functionality.
2Use of energy by moving object
If an external battery pack hangs from the rod, then the reel can be powered, but it interferes with operation and use of the rod
Solution Approach 1:
The battery pack is merged with the rod butt assembly, eliminating the need for hanging external packs. This integration resolves the contradiction by making the power source part of the rod's structure, thereby eliminating interference with operation while maintaining power supply.
3Use of energy by moving object
If a long power cord is used to provide power from the boat, then the reel can be powered, but the dangling cord may interfere with movement and cause entanglements and injuries
Solution Approach 1:
The patent extracts the power source from external locations (boat or hanging packs) and places it directly into the rod butt assembly. This extraction eliminates the need for long power cords and dangling connections, thereby removing the safety hazards associated with entanglements and injuries while maintaining power supply functionality.
Solution Approach 2:
The battery pack is merged with the rod butt assembly, creating an integrated power source that eliminates the need for external power cords. This merging resolves the contradiction by removing the harmful dangling cord while maintaining power supply to the electric reel.
4Device complexity
If fixed single configuration systems are used to integrate battery and reel, then integration is achieved, but the ability to easily change reels or replace depleted battery packs is lost
Solution Approach 1:
The patent segments the rod system into modular components: a removable rod butt assembly containing the battery pack, a reel seat assembly, and a rod blank. This segmentation allows the battery pack to be independently replaced and the reel to be changed without affecting the entire rod, thereby maintaining adaptability while achieving integration.
Solution Approach 2:
The rod butt assembly is designed to be selectively removable and replaceable, introducing dynamic flexibility to the otherwise integrated system. This dynamic design allows users to easily swap battery packs or reels as needed, resolving the contradiction between integration and adaptability.

AI summary
A fishing rod assembly for electrically powered fishing reels includes an integrated battery power source located in a removable rod butt of the fishing rod. The rod butt assembly of the fishing rod interfaces with the bottom end of the reel seat with mating male/female ferrule and electrical connectors. A wiring harness extends up through the inside of the reel seat to a power connector egress body located above the reel seat.
