Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional defecation pad treating devices for companion animals are difficult to use and maintain, as they do not effectively absorb animal waste and can cause odor and secondary contamination due to paper tearing during disposal.
Innovation Solution
A rod for a defecation pad featuring a first and second shaft with magnetic fastening elements, teeth, and protrusions, allowing easy coupling and uncoupling, combined with a defecation pad treating device that includes a winding frame, cover, and motor for rotating the rod to replace soiled pads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional defecation pad treating devices are used, then waste absorption function is provided, but the device is difficult to use and maintain due to hard pad removal and replacement
Solution Approach 1:
The rod is divided into two separate shafts (first shaft and second shaft) that can be easily coupled and separated. This segmentation allows the used pad to be easily removed by separating the shafts, and a new pad to be quickly installed by coupling the shafts again, directly solving the difficulty of pad replacement while maintaining simple device structure
Solution Approach 2:
The coupling mechanism between the two shafts is designed to be dynamically changeable - easily coupled together and easily separated when needed. The shafts can be firmly held together during operation but can be quickly detached for pad replacement, providing operational flexibility without increasing overall device complexity
2Reliability
If paper is used for waste absorption, then basic absorption function is provided, but the paper does not absorb waste well and causes bad odor and secondary contamination
Solution Approach 1:
The material of the defecation pad is changed from conventional paper to a specialized absorbent material with superior absorption parameters. This material change enables effective waste absorption, prevents saturation, and eliminates the problems of bad odor and secondary contamination that occur with paper, while maintaining the simple rod structure for pad replacement
3Ease of operation
If the rod structure is simplified for easy pad replacement, then ease of operation is improved, but the pads may not remain tightly wound
Solution Approach 1:
The two shafts are designed with asymmetric coupling surfaces - one shaft has a convex portion that fits into a concave portion of the other shaft. This asymmetric design provides a firm, stable connection that keeps pads tightly wound during operation, while still allowing easy coupling and separation when pad replacement is needed
Solution Approach 2:
The coupling surfaces of the shafts incorporate curved or rounded features that help maintain the cylindrical shape of wound pads. The curved surfaces distribute pressure evenly around the pad, keeping it tightly wound and stable during use, while the overall rounded shaft design facilitates smooth coupling and decoupling operations
