Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metering pumps lack access protection and flexibility in adjusting dosing quantities, leading to potential misuse and undesirable dosing situations, especially in applications like washing machines and swimming pool control systems.
Innovation Solution
Incorporating a receiving element that can receive dosing information wirelessly from an external transmitting element, with a memory element for storing this information and an energy supply unit to obtain the necessary electrical energy, allowing for secure and flexible adjustment of dosing processes without the need for a separate power supply or battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a metering pump is designed without access protection (simple design), then ease of operation is improved, but reliability deteriorates due to potential misuse and unauthorized changes
Solution Approach 1:
The patent replaces mechanical access protection (physical switches, covers) with a wireless communication system. The transmitting element and receiving element enable authorized personnel to adjust dosing parameters remotely via wireless signals, eliminating the need for physical access to the pump's control interface while maintaining operational flexibility.
Solution Approach 2:
The patent introduces an intermediary wireless communication system between the operator and the metering pump. The transmitting element (external device) and receiving element (integrated in pump) act as mediators, allowing authorized users to send adjustment commands wirelessly while preventing unauthorized direct access to the pump's control mechanisms.
2Adaptability or versatility
If dosing information is adjusted via wireless transmission, then adaptability is improved, but device complexity increases due to additional components
Solution Approach 1:
The receiving element is designed to perform multiple functions: it receives wireless signals for dosing parameter adjustment, stores the received information in a memory element, and triggers the pump operation based on this information. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The patent combines the receiving element, memory element, and control logic into an integrated system within the metering pump. The transmitting element and receiving element work as a unified wireless communication system, merging multiple functions into cohesive components rather than separate isolated elements.
3Ease of operation
If energy is supplied wirelessly for receiving and storing dosing information, then ease of operation is improved, but use of energy increases due to additional power requirements
Solution Approach 1:
The metering pump serves itself by using the wireless energy transmission to simultaneously power the receiving element and memory element. The system draws the necessary energy wirelessly from the transmitting element, eliminating the need for separate battery compartments, power switches, or external power connections.
Solution Approach 2:
The wireless energy transmission system performs multiple functions: it provides power to the receiving element, powers the memory element for storing dosing information, and enables the pump operation. This multi-functional energy supply reduces the need for separate power sources and simplifies the overall system.
