Vertical Dog Urinal Pipe with Lid and Drainage
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
4Object-affected harmful factors
If absorbing paper is frequently replaced, then hygiene is maintained, but personal interaction and agreement with property owners is necessary
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.
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.
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
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.
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.
