Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brushed DC electric motor is used to provide driving force for the reel, then the motor can operate in harsh saltwater environments, but the metallic brushes are highly susceptible to corrosion related failure
Solution Approach 1:
The patent replaces the mechanical brush contact system with a brushless DC motor design. The motor housing is sealed to the reel body, eliminating exposed metallic brushes that would otherwise be susceptible to corrosion from saltwater exposure. This substitution of the motor design fundamentally resolves the corrosion issue while maintaining electrical functionality.
2Speed
If a single speed motor is used in the reel, then the device complexity is reduced, but the fishing reel is limited to having but a single, relatively slow speed
Solution Approach 1:
The patent incorporates a variable speed motor control system that allows the reel to operate at multiple speeds rather than a fixed single speed. The control mechanism enables dynamic adjustment of motor speed to match different fishing conditions, such as adjusting retrieval speed for different line lengths or target fish species. This dynamic capability provides operational flexibility while managing complexity through integrated control.
3Productivity
If manual retrieval of fishing line is used, then the device complexity is minimized, but the process is time consuming and laborious for deep drop techniques
Solution Approach 1:
The patent implements a motorized drive system that automatically performs the line retrieval function without requiring continuous manual operation. The motorized reel can autonomously wind in the fishing line at controlled speeds, freeing the angler to focus on other aspects of fishing such as bait preparation or fish handling. This automation dramatically reduces the time and physical effort required for line retrieval compared to manual operation.
4Ease of operation
If no remote control actuation is provided, then the device complexity is reduced, but the fishing reel lacks remote control capability
Solution Approach 1:
The patent incorporates a remote control system that acts as an intermediary between the angler and the motorized reel. The remote control device transmits signals to the reel's control system, allowing the angler to operate the reel from a distance without being physically close to the mechanism. This intermediary system enables convenient operation while managing complexity through wireless communication protocols and integrated control circuitry.

AI summary
A motor driven fishing reel is provided. The motor driven fishing reel can include a detachable battery pack configured to supply power to a motorized drive assembly within the motor driven fishing reel. The battery pack can include a power output adaptor that can be engaged with a power input adaptor on the motor driven fishing reel. Alternatively, the power input adaptor can accept power from an external source. The battery pack can include one or more protrusions to engage with one or more receiving channels on the motor driven fishing reel such that the battery pack can easily be attached and detached from the motor driven fishing reel.
