Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid distribution systems for vehicles require long distribution lines and complex, space-consuming actuation devices for fluid ejection, which are not economical.
Innovation Solution
A fluid distributor with a movable piston and deformable diaphragms that switches fluid paths between two outlets, using an electromagnetic actuator for control, allowing efficient and economical actuation with minimal line length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a single liquid distribution line is used to limit the length of the distribution line, then the distribution line length is reduced, but each nozzle requires an actuating device which increases device complexity and space occupation
Solution Approach 1:
The patent combines multiple fluid distribution functions into a single integrated device with multiple outlets. The distributor body integrates multiple fluid paths and control mechanisms, eliminating the need for separate actuating devices at each nozzle location while maintaining the ability to independently control multiple ejection points.
Solution Approach 2:
The distributor device performs multiple functions: it distributes fluid to multiple outlets, independently controls each outlet through integrated actuators, and maintains compact positioning. This multi-functional integration reduces the need for separate specialized components at each nozzle location.
2Ease of operation
If each nozzle is combined with an actuating device for independent control, then independent control is achieved, but the space occupied by each nozzle increases
Solution Approach 1:
Multiple actuating functions are merged into a single distributor body. The distributor integrates multiple actuators and control mechanisms in one location, allowing independent control of multiple outlets without requiring separate actuating devices at each distant nozzle location.
Solution Approach 2:
The distributor acts as an intermediary device between the fluid source and the nozzles. It provides centralized control functionality, mediating the fluid distribution and actuation commands to multiple outlets without requiring each nozzle to have its own complete actuating system.
3Adaptability or versatility
If a 4-way switching valve is used for fluid switching, then fluid path control is achieved, but the structure becomes complex
Solution Approach 1:
The fluid distribution system is segmented into multiple independent outlets, each with its own control mechanism integrated into the distributor body. This segmentation allows for simplified individual control paths rather than a single complex multi-way valve, making the overall structure more manageable and less complex.
