Pheromone Dispensing Decorative Stone for Canine Waste Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dog owners face challenges in controlling where their pets eliminate waste, as excessive nitrogen in animal waste damages vegetation, and existing methods for training pets to use specific areas are time-consuming and ineffective.
Innovation Solution
A molded decorative stake with an openable reservoir for containing liquid pheromones that can influence canine elimination behavior, featuring a design for consistent scent dispersion over time, easy refilling, and protection from water and unwanted access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pheromones are dispensed continuously to attract canines, then the training effectiveness is improved, but the scent substance is depleted quickly requiring frequent refilling
Solution Approach 1:
The device uses capillary wick material that periodically draws pheromone liquid from the reservoir through capillary action, providing periodic scent release rather than continuous depletion. This extends the duration of scent dispensing and reduces refilling frequency while maintaining training effectiveness.
Solution Approach 2:
The invention employs porous wick material (such as cotton or other absorbent materials) that utilizes capillary pores to slowly transport pheromone liquid from the reservoir to the dispensing surface. The porous structure controls the rate of scent release, extending the operational duration before refilling is needed.
2Ease of operation
If the reservoir is easily accessible for refilling, then ease of operation is improved, but the pheromone liquid may be contaminated or accessed by animals
Solution Approach 1:
The device is segmented into a removable cover portion and a base reservoir portion. The cover can be detached to access the reservoir for refilling, while the base remains stationary in the ground. This segmentation allows easy refilling operation while the cover protects the liquid when closed, preventing contamination and animal access.
Solution Approach 2:
The removable cover acts as an intermediary between the user and the pheromone reservoir. When closed, it protects the scent substance from contamination and animal access. When opened by the user, it provides access for refilling. This intermediary component resolves the contradiction between accessibility and protection.
3Ease of manufacture
If the device structure is simple for easy manufacture, then manufacturing cost is reduced, but protection from water and animal access is compromised
Solution Approach 1:
The device is divided into simple segmented components: a base with reservoir and a separate cover. Each component is structurally simple and easy to manufacture, yet together they provide effective protection. The simplicity of individual parts maintains ease of manufacture while the assembled structure delivers the required protection capability.
Solution Approach 2:
The cover portion functions as a protective shell that seals the reservoir opening. This simple shell structure provides effective protection from water and animal access while being easy to manufacture. The cover can be made from simple molded plastic or other easy-to-form materials.
