Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pond fertilizer devices either rely on expensive and failure-prone electric motors for controlled fertilizer release or fail to provide effective mixing, leading to inefficient fertilizer distribution and clumping.
Innovation Solution
A floating pond fertilizer device with a tray and floatation ring that uses wind and water movement to rotate mixing arms within the tray, ensuring a controlled release of granular fertilizer through holes in the tray bottom, eliminating the need for motors and preventing clumping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric motors are used for automated fertilizer distribution, then controlled release of fertilizer is achieved, but device cost increases and reliability decreases due to electronic components subject to failure
Solution Approach 1:
The patent removes the motor and electronic control system from the fertilizer distribution device, extracting the problematic components that reduced reliability. Instead, it uses a passive floatation-based mechanism where a floating platform automatically distributes fertilizer through gravity and water movement, eliminating points of failure while maintaining controlled release functionality.
Solution Approach 2:
The device uses self-service principles by employing a floating platform that automatically positions itself and distributes fertilizer without external power sources. The system leverages natural water movement and gravity to achieve fertilizer distribution, making the device self-regulating and free from electronic control failures.
2Device complexity
If non-motorized devices are used for fertilizer distribution, then device cost and complexity are reduced, but controlled release of fertilizer over extended periods is not effective
Solution Approach 1:
The patent employs dynamic principles by allowing the floating platform to move with water currents and waves, creating natural mixing and distribution actions. The platform's floating nature enables it to respond dynamically to environmental conditions, maintaining effective fertilizer release over extended periods without requiring motorized control mechanisms.
3Device complexity
If fertilizer is distributed without mixing mechanism, then device complexity is reduced, but fertilizer forms clumps that do not distribute effectively
Solution Approach 1:
The patent utilizes hydraulic principles by leveraging water movement and wave action to naturally mix and distribute the fertilizer. The floating platform's interaction with water creates turbulence and flow patterns that prevent clumping and ensure effective distribution, eliminating the need for mechanical mixing devices while maintaining high distribution efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves a steady, controlled release of fertilizer over an extended period without motorized components, enhancing fertilizer distribution efficiency and preventing clumping, thereby maximizing fish production in ponds.
Implementation Method 1
The tray is secured to a float that supports the tray to keep the tray on the surface of the water
Implementation Method 2
The wind fan catches wind in order to cause the device to rotate when floating on the surface of the water
Implementation Method 3
The support arm is free to rotate within the central opening so that the opposing mixing arms will mix the granular fertilizer contained in the tray when the support arm is rotated
Implementation Method 4
The bottom of the tray has a plurality of holes extending through the bottom, which allow a controlled release of the fertilizer contained in the tray through the holes in the bottom of the tray
Data Source
AI summary
A floating pond fertilizer device is provided. The device includes a tray for holding fertilizer at the surface of a body of water to be fertilized. The tray has small holes in the bottom of the tray through which fertilizer is released and is secured to a float to support the tray on the surface of the water. The device has opposing mixing arms positioned inside the tray for mixing the fertilizer. The mixing arms are attached to a support arm that can freely rotate within an opening in the center of the bottom of the tray. Rotation of the support arm is facilitated by natural wind and wave action, and thus the device does not require the use of motorized or automated components for mixing or dispensing the fertilizer.
