Solution Overview

Problem

Existing dog urinals fail to effectively manage urine marking in public areas, leading to damage and hygiene issues, as they require frequent maintenance, are prone to damage, and do not attract multiple dog heights or sizes, and often necessitate personal interaction and agreement with property owners.

Innovation Solution

A vertically situated hollow pipe dog urinal with through holes and a capture container at the bottom, equipped with a lid and a draining system, allowing urine to flow inside while capturing a strong scent for marking and draining excess, with a base for stability and easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a free pipe is attached to a bushing or arm in public areas, then dogs can mark their territory, but the pipe requires frequent replacement of absorbing paper and manual cleaning maintenance

Engineering Contradiction:
Improveease of useVSAvoidmaintenance complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The urinal system automatically drains urine through gravity-fed pipes to a collection reservoir, eliminating the need for manual cleaning and absorbing paper replacement. The system serves itself by using the natural flow of urine to rinse the collection area and drain it away automatically.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The harmful function of urine accumulation is extracted by separating the marking function (pipe where dogs urinate) from the waste containment function (buried reservoir). The urine is immediately drained away from the visible pipe through underground piping, removing the maintenance burden from the above-ground structure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-generated harmful factors

If a pipe without lid is used, then rain water washes away the smell track, but the smell signal for dogs is lost

Engineering Contradiction:
Improvesmell track preservationVSAvoidrain water impact
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The lid design creates asymmetric protection: it shields the interior collection area from rain while maintaining an opening or ventilation that allows urine vapor and smell to escape and disperse into the environment, attracting dogs to the location.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The lid acts as an intermediary element that selectively filters what enters the collection area. It blocks rain water (harmful) while allowing smell molecules to pass through (useful), mediating between the two opposing requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If a horizontal arm structure is used to attach the pipe, then the pipe can be mounted, but it creates additional surfaces for dogs to mark and requires wall or pole attachment agreements

Engineering Contradiction:
Improveinstallation easeVSAvoidattachment location flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The solution moves from horizontal mounting (requiring walls/poles) to vertical ground-mounted installation. The pipe is positioned vertically above ground level, accessible to dogs of various heights, while the base is anchored directly to the ground, eliminating the need for wall attachment agreements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Object-affected harmful factors

If absorbing paper is frequently replaced, then hygiene is maintained, but personal interaction and agreement with property owners is necessary

Engineering Contradiction:
Improvehygiene conditionVSAvoidmaintenance time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system automatically maintains hygiene through continuous drainage. Urine flows through the pipe and drains into a buried reservoir, preventing accumulation and eliminating the need for manual cleaning interventions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The hydraulic principle of gravity-driven flow is used to continuously rinse and drain urine away from the pipe. The system uses the natural flow of liquid to maintain cleanliness without mechanical cleaning devices or manual intervention.

Inventive Principle:
Principle #29Pneumatics and hydraulics

5Adaptability or versatility

If the urinal is not attached to the ground, then it can be transported, but urine is freely accessible and hygiene conditions worsen

Engineering Contradiction:
ImprovetransportabilityVSAvoidurine accessibility
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The urinal pipe is merged with a ground-anchored base structure. The base provides stable ground attachment and houses the drainage system, while the pipe extends upward for dog access. This combination ensures both stability and proper urine containment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The drainage function is extracted and placed in a separate buried reservoir system. Urine is immediately channeled away from the accessible pipe area into the underground containment system, preventing free access to accumulated urine and maintaining hygiene.

Inventive Principle:
Principle #2Taking out (Extraction)
