Solution Overview

Problem

Existing pet grooming processes are labor-intensive, inefficient, and wasteful, requiring repeated manual scrubbing and significant water usage, leading to increased costs and resource consumption.

Innovation Solution

A self-circulating pet shower machine that recycles shampoo and clean water, utilizing a motor-driven impeller system to create a circulating flow for efficient pet grooming, incorporating features like a booster plate, sealing rings, and a showerhead with a comb-shaped massage head to reduce manual effort and water waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual scrubbing is used to clean pets, then the pet can be cleaned, but the labor intensity increases and cleaning efficiency decreases

Engineering Contradiction:
Improvelabor intensityVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements an automated pet shower system where the water circulation system, spray nozzles, and roller brushes work together to clean the pet automatically without requiring manual scrubbing. The system circulates water through the pet's fur using spray nozzles and rolling brushes, eliminating the need for manual intervention while maintaining effective cleaning.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical scrubbing with an automated mechanical system consisting of a water circulation pump, spray nozzles, and roller brushes. The motor-driven water circulation system automatically directs water flow and mechanical brushing action to clean the pet, substituting human labor with automated mechanical components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual scrubbing with repeated rinsing is performed, then the pet's fur can be cleaned thoroughly, but water resources are wasted significantly

Engineering Contradiction:
Improvecleaning qualityVSAvoidwater waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent implements a water recovery and recycling system where used water is collected from the bathing container, filtered through a filtration system to remove impurities and pet hair, and then reused for subsequent bathing cycles. This closed-loop water management system significantly reduces water consumption while maintaining thorough cleaning quality through multiple spray and brushing cycles.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The patent employs a continuous water circulation system that constantly recycles and reuses water throughout the bathing process. Instead of draining and refilling water multiple times, the system continuously circulates filtered water through spray nozzles and brushing mechanisms, maintaining effective cleaning while minimizing water waste through uninterrupted reuse.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If multiple rinsing cycles are performed to clean pet fur, then cleaning effectiveness improves, but grooming time increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidgrooming time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a continuous automated bathing cycle that performs multiple cleaning operations without interruption. The motor-driven system continuously circulates water through spray nozzles and activates roller brushes in sequence, maintaining effective cleaning through repeated exposure while eliminating the time loss associated with manual setup and breakdown between rinsing cycles.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent employs periodic automated cycles of spraying and brushing that repeat automatically throughout the bathing process. The motor controller activates spray nozzles and roller brushes in alternating periodic intervals, ensuring thorough cleaning through multiple cycles while reducing total grooming time by eliminating manual intervention between cycles.

Inventive Principle:
Principle #19Periodic action

AI summary

The self-circulating pet shower machine comprises a top case with protrusions inside, a bottom case connected to the top case by bolts, and a motor. The middle portion of the motor has stops abutting the protrusions, with a first sealing ring between the top face of the bottom case and the stops. A shock-absorbing gasket sits between the stops and the protrusions. A booster plate beneath the motor and outlet port features inlet holes with helical guide grooves. An impeller includes an inlet port surrounded by a circular baffle. A water guide bottom plate has an inner periphery surrounded by an outer periphery. The inner periphery is embedded in the circular baffle of the impeller, and the outer periphery is secured to the side wall of the bottom case by the bolts.
