Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pumping apparatuses are inefficient in handling a wide range of free-flowing materials, particularly struggling with suspensions that tend to deposit and block the system, and are often tailored to specific products like powders or liquids.
Innovation Solution
A vertically extending cylindrical pump chamber with a filter element and a float member for separating liquids and powders, equipped with multiple supply and drainage pipes, allows for the efficient pumping and volumetric proportioning of liquids, powders, suspensions, and pastes using a T-shaped connecting pipe with shut-off valves and a movable apex chamber for effective separation and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pumping apparatus is designed for specific products (powders or liquids), then the pumping efficiency for that specific product is improved, but the adaptability to handle different types of materials (liquids, powders, suspensions, pastes) deteriorates
Solution Approach 1:
The pump chamber is designed with a universal structure that can handle multiple types of materials (liquids, powders, suspensions, pastes) through a single integrated system. The chamber can be configured to pump different materials by adjusting operational parameters rather than requiring separate specialized equipment for each material type.
Solution Approach 2:
The apparatus incorporates dynamic elements including a movable diaphragm that can adapt its position and movement characteristics based on the material being pumped. The system can dynamically adjust pumping parameters such as pressure, flow rate, and diaphragm motion to optimize performance across different material types while maintaining a unified pump structure.
2Adaptability or versatility
If a pumping apparatus handles suspensions, then the versatility is improved, but the reliability deteriorates due to deposition and blockage in pipes and valves
Solution Approach 1:
The pumping system is divided into separate functional zones: a pump chamber for material processing, a separation chamber for liquid-powder separation, and dedicated discharge paths for each material type. This segmentation prevents suspension materials from clogging common pipes and valves by routing them through separate channels and allowing controlled discharge of different materials.
Solution Approach 2:
A separation chamber acts as an intermediary between the pump chamber and the discharge system. This intermediate zone allows suspensions to be separated into liquid and powder components, preventing the mixture from traveling through pipes and valves where it would cause blockages. The separation chamber can be configured with filters or centrifugal separation mechanisms.
3Manufacturing precision
If a filter element is used to separate liquid and powder, then the separation efficiency is improved, but the device complexity increases
Solution Approach 1:
The filter element is designed to serve multiple functions: separating liquid from powder during pumping operations, and potentially serving as a cleaning mechanism when reversed or combined with flushing operations. This multi-functionality reduces the need for separate specialized components for each function.
Solution Approach 2:
The filter system can be made dynamically controllable, allowing the filter element to be selectively engaged or disengaged based on the material being processed. The filter can be dynamically cleaned or reversed during operation, reducing the need for complex manual intervention and maintenance systems.
4Productivity
If multiple supply pipes for multiple products are provided, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The supply system is segmented into separate pipes for different materials (liquids, powders, suspensions), allowing independent control and volumetric proportioning of each material type. This segmentation enables simultaneous pumping of multiple products through dedicated channels, preventing interference between different materials.
Solution Approach 2:
Multiple supply pipes are merged into a unified control system that manages all material flows through a single pump chamber. The pump chamber serves as a common processing zone where different materials can be combined or processed separately, and the volumetric proportioning mechanism integrates control of all supply pipes through a single operational interface.
