Heated Pet Mat Truncated Circle Design for Round Doghouses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heated pet mats for rectangular doghouses do not fit in round doghouses, leading to significant waste and increased costs when attempting to manufacture round or semicircular mats, making them economically unviable for the market.
Innovation Solution
A heated pet mat with a fire retardant covering in the shape of a truncated circle, folded in half to form two layers, containing a resistive heating element sandwiched between them, which is sealed along an edge, using materials like acrylonitrile butadien styrene or polyvinyl chloride plastic, reducing material waste by 20% compared to circular designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If round or semicircular heated pet mats are manufactured to fit round doghouses, then the mats can be used in round doghouses, but material waste increases by over 20% of total plastic area
Solution Approach 1:
The circular heating element is divided into two semicircular sections that are positioned side by side. Each semicircular section is covered by a separate plastic layer, allowing the heating element to fit efficiently within a rectangular boundary while maintaining circular heating coverage. This segmentation eliminates the need to cut circular shapes from rectangular plastic sheets, reducing material waste.
Solution Approach 2:
The invention transitions from a single circular mat design to a dual semicircular configuration arranged in a rectangular footprint. By utilizing two-dimensional arrangement of semicircles rather than a single circle, the design achieves both circular heating effectiveness and rectangular material efficiency, fitting perfectly within rectangular plastic sheets without excessive waste.
2Loss of substance
If rectangular heated pet mats are used, then material waste is minimized, but the mats do not fit in round doghouses
Solution Approach 1:
The heating element uses two asymmetric semicircular sections rather than a symmetric full circle or rectangle. Each semicircle is positioned to maximize space utilization within the rectangular plastic sheet while collectively providing circular heating coverage. This asymmetric arrangement allows efficient material usage while achieving compatibility with round doghouses.
3Adaptability or versatility
If full circular plastic sheets are used for round mats, then the mats fit round doghouses perfectly, but manufacturing costs increase due to 20% material waste
Solution Approach 1:
The invention changes the geometric parameters of the plastic covering from circular to rectangular, and the heating element from a single circle to two semicircles. This parameter change allows the plastic sheets to be cut from rectangular stock without waste, while the semicircular arrangement maintains circular heating effectiveness. The manufacturing cost is reduced by eliminating the 20% material waste associated with circular cutting.
