Senior Pet Litterbox with Sloped Internal Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional litterboxes are difficult for senior and arthritic animals to use due to their design, which can cause pain and discomfort, leading to avoidance as the animals associate the litterbox with joint pain, especially since they often mask their pain symptoms.
Innovation Solution
A litterbox design featuring an entrance ramp and internal platform that reduces the need for stepping over a wall, along with a rubberized pad for traction, to alleviate joint strain during use, incorporating a basin with a downward-sloping internal platform and a rubberized pad for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional litterbox with a lip around the entire edge is used, then the litterbox structure is simple and complete, but it becomes difficult and painful for animals with arthritis to enter and exit
Solution Approach 1:
The patent removes the lip from specific portions of the litterbox perimeter, creating open areas that allow arthritic animals to enter and exit without having to step over a barrier. This extraction of the lip element from problematic locations directly addresses the ease of operation for disabled animals while maintaining the basic litterbox structure.
Solution Approach 2:
The litterbox perimeter is segmented into different zones: some areas have lips while other areas have open entrances. This segmentation allows the structure to provide containment where needed while providing easy access points for arthritic animals, resolving the contradiction between structural completeness and ease of operation.
2Ease of operation
If conventional sand-like litter is used, then the litter provides good coverage, but it displaces under the animal's weight and increases pressure on joints
Solution Approach 1:
The patent changes the physical parameters of the litter material from sand-like granules to cushioning material with different density and elasticity properties. This parameter change allows the litter to conform to the animal's body and distribute weight, reducing pressure on joints while maintaining coverage and stability.
3Ease of operation
If the litterbox is designed for easy access with lower walls, then arthritic animals can enter more easily, but the animal may feel exposed or unsafe
Solution Approach 1:
The litterbox applies different structural qualities to different locations: the front and side walls have reduced height or open areas for easy access, while the back wall maintains full height to provide a sense of security and enclosure. This local differentiation allows the structure to simultaneously provide accessibility and psychological comfort.
