Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump arrangements in water-carrying cleaning devices face challenges in efficiently integrating heaters for improved energy efficiency and flexibility, often resulting in suboptimal flow quality and hydraulic efficiency due to rigid design configurations.
Innovation Solution
A modular pump arrangement is introduced, where the adapter separates the hydraulic unit from the drive module, allowing flexible integration of heaters and various hydraulic units, with the adapter defining the fluidic properties and flow design independently of the hydraulic units, enabling adaptable and efficient heating solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the heater is integrated into the pump arrangement, then energy efficiency and heat transfer are improved, but the design flexibility and adaptability are reduced
Solution Approach 1:
The pump arrangement is divided into separate functional modules: a drive module, a hydraulic unit, and an adapter. The heater can be integrated into either the drive module or the hydraulic unit, allowing flexible configuration. This segmentation enables the heater to be positioned optimally for energy efficiency while maintaining design flexibility through modular assembly.
Solution Approach 2:
The adapter serves as an intermediary component that connects the drive module and the hydraulic unit. It provides a standardized interface that allows different configurations of heater integration while maintaining consistent fluidic connections. The adapter enables the system to achieve both integrated heating benefits and design adaptability.
2Volume of moving object
If the heater is integrated into the pump arrangement, then the heat-transferring surface can be made compact, but the flow quality and hydraulic efficiency may deteriorate
Solution Approach 1:
The heater is positioned to provide localized heating at specific points within the fluid path, such as near the suction port or at the impeller inlet. This local quality approach ensures compact heat transfer surfaces are placed where they are most effective, while the overall fluid flow path remains optimized for hydraulic efficiency through properly designed flow channels and minimal obstructions.
3Ease of manufacture
If a rigid design configuration is used for integrating the heater, then manufacturing is simplified, but adaptability to different applications is reduced
Solution Approach 1:
The adapter and modular components are designed with universal interfaces and standardized connection points that can accommodate different heater configurations and positions. The same basic pump assembly can be adapted to various applications by simply reconfiguring which module contains the heater or by adjusting the heater's position within a module, maintaining ease of manufacture while achieving application-specific adaptability.

Function Achieved in This Case
This modular design enhances energy efficiency, flow quality, and adaptability, allowing for application-specific configurations while maintaining consistent fluidic performance across different hydraulic units, thus improving economic efficiency and responsiveness to customer needs.
Implementation Method 1
The heater is essentially a plate-shaped stainless steel sheet in which an electrically operated heating element is embedded
Implementation Method 2
A pump wheel driven by an electric motor builds up the hydraulic pressure required to pump the liquid
Implementation Method 3
In particular due to a relatively high turbulence in the liquid, a comparatively good heat transfer results here
