Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a cap contains the inlet, outlet, filter element, and air pump in one integrated component, then the filtration device is compact and portable, but the cap becomes expensive to manufacture and difficult to clean
Solution Approach 1:
The patent separates the cap components (inlet, outlet, filter element, air pump) from the container body, allowing them to be cleaned separately or replaced as a module. This segmentation resolves the contradiction by maintaining compactness through modular design while improving cleanability by enabling separate handling of each component.
Solution Approach 2:
The patent extracts the complex cap assembly as a removable module that can be taken out for separate cleaning or replacement. This extraction resolves the contradiction by allowing the main container body to be simple and easy to clean, while the cap module can be maintained separately without complicating the overall structure.
2Adaptability or versatility
If the container body has multiple parts and joints to accommodate filter elements and conduits, then the filtration device is functional, but cleaning becomes laborious due to hard-to-reach areas
Solution Approach 1:
The patent segments the filtration system into a simple container body and separate functional modules (filter element, conduit, cap). This segmentation maintains functionality while improving cleanability by eliminating hard-to-reach joints within the container body itself.
Solution Approach 2:
The patent extracts complex functional elements (filter element seating, conduit connections) from the container body walls, placing them in accessible locations or as removable modules. This extraction resolves the contradiction by maintaining functionality while ensuring all container body surfaces are easily accessible for cleaning.
3Reliability
If the filter element is mounted inside the storage area connected to inlet or outlet, then the filtration function is achieved, but the container body requires complex internal structures that are difficult to clean
Solution Approach 1:
The patent segments the filter element as a separate removable module that can be easily accessed and removed from the container body. This segmentation maintains reliable filtration function while improving cleanability by allowing complete removal of the filter element without disassembling the container body.
Solution Approach 2:
The patent designs the filter element mounting to be preliminarily positioned in accessible locations with easy access mechanisms. This preliminary positioning resolves the contradiction by ensuring the filter element can be easily installed and removed before contamination occurs, maintaining filtration reliability while enabling easy maintenance.
4Reliability
If the outlet is located on top of the vessel with an external riser pipe, then the filtration device is functional, but repeated cleaning of the vessel becomes laborious
Solution Approach 1:
The patent segments the riser pipe and outlet as separate components that can be easily accessed and cleaned independently from the container body. This segmentation maintains functional filtration while improving cleanability by allowing separate maintenance of the outlet system without laborious cleaning of the vessel interior.
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
Facilitates easy handling and cleaning of the filtration device by eliminating the need for manual disassembly and reducing laborious cleaning efforts, ensuring all parts are accessible and easily sanitized.
Implementation Method 1
A suitable filter element is arranged in the flow path between the inlet and the outlet of the container body
Implementation Method 2
By manually or automatically operating the air pump a pressure increase inside of the bottle can be generated, resulting in a flow of a corresponding amount of water from the inside of the bottle through the filter element
