Canine Diaper Band With Urine Color-Change Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canine diaper technologies lack effective means to visually indicate urination and prevent urine leakage, particularly for indoor use.
Innovation Solution
A wearable band with an impermeable material, an integrated absorbent pad, and a reactive strip that changes color upon exposure to urine, ensuring urine absorption and visual notification of urination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a wearable band with absorbent pad is used for canine urine absorption, then urine absorption capability is improved, but visual indication of urination is lacking
Solution Approach 1:
The patent incorporates a reactive strip containing pH-sensitive dye that changes color when exposed to urine. The strip transitions from its initial color to a different color indicating urination has occurred, providing visual feedback to the user without requiring electronic components.
Solution Approach 2:
The reactive strip acts as an intermediary between the absorbent pad and the user. It detects the presence of urine through pH change and translates this chemical information into visual information that can be easily observed, bridging the gap between urine absorption and user awareness.
2Loss of information
If a reactive strip is integrated into the band, then visual communication of urination is improved, but device complexity increases
Solution Approach 1:
The reactive strip is integrated into a disposable diaper assembly rather than being a permanent component. This allows the use of simple chemical indicators without requiring durable, complex construction, as the entire assembly is replaced after use rather than maintained long-term.
Solution Approach 2:
The reactive strip automatically detects and indicates urination through its chemical properties without requiring external power sources, electronics, or user intervention. The pH-sensitive dye self-activates upon contact with urine, providing indication without adding mechanical or electronic complexity.
3Object-affected harmful factors
If fluid impermeable material is used in the band, then urine leakage prevention is improved, but breathability and comfort may be reduced
Solution Approach 1:
The fluid impermeable material is strategically placed only in areas where leakage prevention is critical, such as the inner layer contacting the absorbent pad and strategic seams. Other areas of the band maintain breathability and flexibility, creating a balance between leakage protection and comfort without requiring the entire band to be impermeable.
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
Effectively absorbs urine and prevents leakage while providing a visual cue for timely diaper change, enhancing cleanliness and convenience for pet owners.
Implementation Method 1
A reactive strip is integrated into the band and the reactive strip is comprised of a material which chemically reacts to urine. Furthermore, the reactive strip changes colors when the reactive strip is exposed to urine
Implementation Method 2
An absorbent pad is integrated into the band to absorb urine from the canine
Data Source
AI summary
A canine diaper assembly includes a band that is wearable around a canine's body. The band is constructed of a fluid impermeable material to inhibit urine of the canine from passing through the band. A first tab is coupled to and extends away from the band and a second tab is coupled to and extends away from the band. The second tab is matable to the first tab for retaining the band in a closed loop around the canine's body. An absorbent pad is integrated into the band to absorb urine from the canine. A reactive strip is integrated into the band and the reactive strip is comprised of a material which chemically reacts to urine. The reactive strip changes colors when the reactive strip is exposed to urine to visually communicate that the canine has urinated into the absorbent pad.
