Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flotation devices for dogs, whether designed for humans or specifically for dogs, are either prone to puncture, difficult to mount, and fail to provide stability and freedom of movement, leading to safety concerns and heat exposure risks.
Innovation Solution
A non-inflatable, semi-submersible flotation apparatus with a water-permeable housing membrane and a nested configuration of flotation rods provides buoyancy and stability, allowing dogs to sit, lay, and move safely in water of any depth, while accommodating various sizes and preventing heat exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inflatable flotation devices are used, then buoyancy is provided, but they are susceptible to puncture and ripping
Solution Approach 1:
The patent uses a flexible, non-inflatable membrane structure that distributes mechanical stresses across the entire surface area rather than concentrating them at weak points. This membrane design eliminates the puncture and ripping issues inherent in inflatable devices while maintaining buoyancy through the distributed flotation rod system.
Solution Approach 2:
The flotation device is segmented into multiple independent flotation rods distributed throughout the structure. This segmentation means that if one rod is damaged, the others continue to provide buoyancy, significantly improving overall reliability and resistance to puncture and ripping.
2Reliability
If dog floats are designed to keep dogs completely out of water, then flotation is provided, but dogs are exposed to sun and heat without cooling
Solution Approach 1:
The device provides partial submersion rather than complete flotation, allowing the dog's body to be partially immersed in cooling water while maintaining sufficient buoyancy. This partial action approach simultaneously achieves both flotation capability and thermal regulation.
Solution Approach 2:
Different portions of the dog's body experience different conditions - the lower portions in water receive cooling while the upper portions remain above water for breathability. This local quality differentiation allows simultaneous achievement of flotation and heat dissipation.
3Ease of operation
If current flotation devices are designed, then basic flotation is provided, but they fail to accommodate dog's freedom of movement and stability
Solution Approach 1:
The flotation device uses a dynamic structure with multiple independent flotation rods that can flex and adjust as the dog moves. This dynamic configuration maintains stability during movement while accommodating the dog's freedom of motion, unlike rigid traditional flotation devices.
Solution Approach 2:
The flotation rods are arranged in a nested configuration where smaller rods are positioned within the framework of larger rods. This nested structure provides multiple levels of support and stability while allowing the dog to move freely within the accommodated space.
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 solution ensures the dog's safety and comfort by providing stability and freedom of movement, preventing punctures, and allowing for effective cooling through partial submersion, addressing the limitations of existing devices.
Implementation Method 1
the periphery portion provides a buoyancy so that the interior portion becomes semi-submerged when the device is place on a body of water
Implementation Method 2
A water permeable housing membrane having an interior portion connected to and defined by a peripheral portion

AI summary
An animal flotation device is provided. The animal flotation device is a non-inflatable, semi-submersible flotation apparatus for a dog to stably sit, lay and move about while partially submerged in a body of water of any depth. The animal flotation device may have a peripheral portion defining an interior portion. The interior portion provides a generally rigid area adapted to become semi-submersed within the body of water when supporting the dog, whereby the peripheral portion provides buoyancy and stability to the semi-submersed interior portion so that the dog may move around and feel safe while floating atop the body of water.
