Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveying devices in vehicles, such as water pumps and compressors, require complex valve systems for fluid flow distribution, leading to high component costs and limited adjustability of fluid flows.
Innovation Solution
A conveying device with a rotatable ring element and axially spaced outlet openings, allowing independent division of fluid volume flow and finer adjustment through a parting plate, enabling better control of fluid flow without inhibiting the flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If valve systems are used for fluid flow distribution, then fluid flow control is achieved, but component costs increase and device complexity increases
Solution Approach 1:
The patent extracts the flow control function from complex valve systems and implements it through a simplified mechanism consisting of a rotatable ring element with adjustable orifices and a parting plate. This removes the need for separate valve components while maintaining flow control capability, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The rotatable ring element serves multiple functions: it acts as both a flow distribution mechanism and an adjustment mechanism, while the parting plate provides additional flow division capability. This multi-functionality consolidates what would traditionally require multiple separate valve components into a single integrated structure, reducing device complexity while maintaining operational control
2Ease of operation
If valve systems are used for fluid flow distribution, then fluid flow control is achieved, but component costs increase
Solution Approach 1:
The patent merges the flow control function and flow distribution function into a single integrated ring element structure, eliminating the need for separate valve bodies, actuators, and mounting hardware. This consolidation reduces the total number of components that need to be manufactured and assembled, directly lowering component costs while maintaining full fluid flow control capability
Solution Approach 2:
The ring element with its rotatable design and adjustable orifices provides universal flow control capability for multiple outlet openings, replacing what would traditionally require multiple specialized valve components. This multi-functional design reduces the overall bill of materials and manufacturing complexity, addressing the cost issue directly
3Device complexity
If a single outlet opening is used, then device structure is simple, but fluid flow adjustability is limited
Solution Approach 1:
The patent segments the single outlet opening into multiple outlet openings (first and second outlet openings) that are axially spaced apart. The parting plate further segments the fluid flow into separate partial flows for each outlet. This segmentation allows independent control and adjustment of flow to different outlets, dramatically increasing adaptability while the overall structure remains relatively simple
Solution Approach 2:
The patent introduces axial spacing between outlet openings as a new dimension for flow distribution. By spacing outlets axially rather than just radially, the design enables independent flow control in the axial direction, adding versatility to the structure without significantly increasing complexity
4Volume of moving object
If outlet openings are positioned close to each other, then device structure is compact, but independent flow division is difficult
Solution Approach 1:
The patent positions outlet openings in the axial dimension rather than only in the radial plane. This axial separation allows the parting plate to effectively divide flows between outlets without requiring large radial spacing, maintaining compact device volume while enabling independent flow division through the axial positioning strategy
