Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet water dispensers use independent brushless and membrane pump motors that are costly, difficult to clean, and inefficient in energy consumption due to non-specific designs.
Innovation Solution
A pet water dispenser with an integrated pump cartridge and housing, featuring a pump motor connected to a pump blade via a shaft, allowing for easy assembly, low cost, and ease of cleaning, and incorporating a filter to improve water quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent brushless pump motor or membrane pump motor is used, then pumping function is achieved, but cost increases and structure becomes complex
Solution Approach 1:
The patent merges the motor and pump functions into a single integrated pump cartridge assembly. The pump cartridge includes a motor housing with a motor, a pump housing with an impeller, and water passages that connect both components. This integration eliminates the need for separate independent motors while achieving the same pumping function, thereby reducing device complexity and cost.
2Reliability
If independent pump motor is used, then pumping function is achieved, but energy consumption increases
Solution Approach 1:
The integrated pump cartridge design allows the motor and pump to work as a unified system with direct coupling. The motor shaft is directly connected to the impeller through the integrated structure, eliminating energy losses from separate motor extensions and intermediate transmission components. This direct integration optimizes energy transmission efficiency.
3Reliability
If existing motor structure is extended, then pump function is achieved, but manufacturing cost increases
Solution Approach 1:
The patent designs a unified pump cartridge that can be manufactured as a single integrated component or pre-assembled unit. The motor housing, pump housing, and connecting water passages form a compact assembly that simplifies manufacturing processes compared to extending existing motor structures. This integrated design reduces part count and assembly complexity, thereby lowering manufacturing costs.
4Stability of the object's composition
If pump cartridge is fixed in pump housing, then structural stability is achieved, but cleaning becomes difficult
Solution Approach 1:
The patent divides the water dispenser into separable modules: the pump cartridge can be detached from the pump housing. The pump cartridge includes the motor and impeller assembly, while the pump housing contains the water passages and filter. This segmentation allows the pump cartridge to be removed for cleaning or replacement while maintaining structural stability during operation through proper connection mechanisms.
