Problem
Conventional agricultural implements connected to agricultural vehicles face issues with power supply disruptions due to damaged wire connections, especially from high-speed operations or environmental factors, leading to control system failures and the need for frequent battery maintenance.
Innovation Solution
The implementation of a self-chargeable battery management unit within the control system of agricultural implements, which generates power by sensing the speed of the implement and provides this power to the control unit, eliminating the need for internal batteries and reducing maintenance requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire connection is used to connect the battery with the power source, then power supply is established, but the wire connection may be damaged due to high running speed of PTO shaft or stones during tillage process
Solution Approach 1:
The patent extracts and eliminates the vulnerable wire connection from the system by implementing a contactless power transfer mechanism using magnetic coupling between the agricultural vehicle and implement, thereby removing the component susceptible to physical damage from stones and high-speed operations
Solution Approach 2:
The patent introduces magnetic field coupling as an intermediary between the power source on the agricultural vehicle and the battery on the implement, enabling power transfer without direct physical wire connection, thus protecting against wire damage while maintaining reliable power supply
2Adaptability or versatility
If terminal connections with the battery are disconnected while disconnecting the agricultural implement, then the implement can be detached, but water and dust protections for the battery are required
Solution Approach 1:
The patent performs preliminary protection by enclosing the battery in a sealed housing with integrated magnetic coupling components before any disconnection occurs, ensuring that the battery remains protected from water and dust throughout the attachment and detachment operations
Solution Approach 2:
The patent merges the battery protection housing with the magnetic coupling mechanism, combining multiple functions (power reception, protection, and contactless coupling) into a single integrated unit that maintains protection during implement detachment
3Reliability
If an internal battery is used in the agricultural implement, then power supply for control system is provided, but frequent battery maintenance is required
Solution Approach 1:
The patent implements self-charging capability where the battery on the agricultural implement automatically recharges from the agricultural vehicle's power source during operation through magnetic coupling, eliminating the need for manual maintenance and ensuring continuous power availability for the control system
