Solution Overview
Problem
Existing pumping devices for domestic water supply face challenges in simplified production and reliable operation due to complex assembly processes and potential leaks leading to pressure loss, which require frequent motor switching on and off.
Innovation Solution
A compact pumping device design integrates the drive motor and fluid pump with a pressure vessel, utilizing plug-in connections and dimensionally stable pipelines for secure fluid-tight connections, along with a pressure switch for pressure regulation and a check valve for efficient fluid flow, ensuring reliable operation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible lines are used to connect the fluid pump and pressure tank, then mechanical positional tolerances are compensated, but the device complexity increases due to additional adapter parts
Solution Approach 1:
The patent integrates the adapter function directly into the pump housing and pressure tank structure. The pump housing includes integrated connection elements that directly interface with the pressure tank, eliminating the need for separate flexible lines and adapter parts. This merging of functions reduces component count while maintaining positional tolerance compensation through the integrated design.
2Adaptability or versatility
If additional adapter parts are used for connection, then mechanical positional tolerances are compensated, but manufacturing complexity and cost increase
Solution Approach 1:
The adapter functionality is merged into the main pump housing and pressure tank structures. These integrated connection elements are manufactured as part of the primary components using standard molding or machining processes, avoiding the need for separate adapter parts that would require additional manufacturing steps, inventory management, and assembly operations.
3Adaptability or versatility
If flexible lines and adapter parts are used, then mechanical tolerances are compensated, but connection reliability decreases due to potential leaks
Solution Approach 1:
The patent creates direct integrated connections between the pump housing and pressure tank, eliminating multiple connection interfaces that could potentially leak. The merged design features continuous sealing surfaces and integrated threading or coupling mechanisms that reduce the number of potential failure points while maintaining the ability to accommodate mechanical tolerances through the integrated structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables simplified assembly, reliable operation, and reduced maintenance costs by providing a compact, space-saving design with secure fluid connections and pressure regulation, preventing frequent motor activation due to pressure loss and ensuring consistent water pressure.
Implementation Method 1
The pressure vessel, which acts as a pressure accumulator, provides a limited volume of pressurized fluid, pressurized by the pump, ensuring a substantially constant water pressure
Implementation Method 2
Push-fit connections, which ensure a fluid-tight connection between a plug receptacle and a pipe section designed for insertion into the plug receptacle immediately upon completion of the insertion process
