Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems struggle to effectively separate dispersively contained droplets of water over a long period of operation without causing damage to the filtration components.
Innovation Solution
A water separating screen is integrated into the filter element, featuring a screen fabric supported by longitudinal struts that allow radial elasticity, preventing tears and tears by allowing the screen fabric to deform under high pressure while maintaining effective separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid screen fabric is used for water separation, then separation effectiveness is improved, but the screen fabric is prone to tearing under high pressure
Solution Approach 1:
The patent employs a flexible screen fabric instead of a rigid one, allowing the fabric to deform elastically under high pressure conditions. This flexibility prevents tearing while maintaining the screening function for water separation. The fabric can temporarily yield to pressure differentials and then return to its original configuration, ensuring long-term durability.
Solution Approach 2:
The patent changes the mechanical parameters of the screen fabric by selecting materials and constructions that provide appropriate elasticity and flexibility. The fabric is designed with specific tensile strength, elongation properties, and pore size characteristics that enable it to withstand varying pressure conditions while effectively separating water droplets from the liquid stream.
2Stability of the object's composition
If the screen fabric is tightly fixed to maintain structural stability, then structural integrity is improved, but the screen fabric cannot deform under pressure causing damage
Solution Approach 1:
The patent transitions from a static, rigid fixation system to a dynamic one where the screen fabric can deform in response to pressure changes. The fabric is secured at boundaries to maintain overall structural integrity, but allowed to move and flex in the interior regions where pressure differentials occur during operation. This dynamic capability enables the fabric to accommodate pressure variations without tearing.
Solution Approach 2:
The patent designs the screen fabric with inherent elastic properties that act as a cushioning mechanism before damage can occur. The material's elasticity allows it to absorb and dissipate pressure shocks and transient overpressures, preventing the harmful effects of pressure-induced damage while maintaining structural integrity during normal operation.
3Device complexity
If a simple screen structure is used, then device complexity is reduced, but water separation effectiveness over long periods is insufficient
Solution Approach 1:
The patent uses a flexible screen fabric that maintains its separation function over long operational periods by elastically adapting to pressure variations. This simple yet flexible structure prevents the degradation and damage that would occur with rigid structures, thereby extending the operational duration without requiring complex reinforcement or multiple replacement components.
Solution Approach 2:
The screen fabric's elastic properties enable it to self-recover from pressure-induced deformations without external intervention. After each pressure cycle, the fabric automatically returns to its original configuration, maintaining its separation effectiveness over thousands of operational cycles. This self-service capability eliminates the need for complex maintenance mechanisms or frequent replacements.
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 effectively separates water droplets without damaging the screen fabric, ensuring prolonged operation and efficient filtration performance.
Implementation Method 1
The outflow of separated droplets of water from the water separating screen into the water collecting space is carried out in the direction of the weight force of the droplets of water
Implementation Method 2
the screen fabric is arranged at and surrounds a radially outer side of the longitudinal struts of the water separating screen. The screen fabric is held and connected only to the carrier rings. In contrast to the carrier rings, the screen fabric is arranged at and may be supported on a radially outer side of the longitudinal struts of the water separating screen but is not held onto or fixedly connected onto the longitudinal struts
