Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cone valves have complex configurations, leading to difficult manufacturing and operation, slow opening and closing, leakage, and high maintenance costs due to turbulence and valve seat abrasion.
Innovation Solution
A cone valve design with a simple configuration featuring a hollow body unit with left and right bodies, a cone with expansion and contraction parts, a cylindrical forward and backward movement unit, and a power transfer system using a motor or handle to open and close the flow passage, minimizing turbulence and abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex configuration with multiple components (sleeve gate, dual screw shaft, bearing housing, spraying guide cover) is used, then the valve can achieve flow control functionality, but the manufacturing difficulty increases and operational complexity increases
Solution Approach 1:
The valve body is divided into left and right body units with distinct functions (inlet and outlet), and the cone is segmented into expansion and contraction parts. This segmentation allows each component to perform its specific function efficiently while simplifying the overall manufacturing process compared to monolithic designs.
Solution Approach 2:
The cone integrates multiple functions into a single component: it serves as both the flow control element and the sealing element through its expansion and contraction parts. The cylindrical forward and backward movement unit combines the actuation mechanism with the cone positioning, reducing the need for separate actuation components.
2Reliability
If a complex configuration with multiple components is used, then the valve can achieve flow control functionality, but the manufacturing procedure becomes hard to implement
Solution Approach 1:
Dividing the valve into modular left and right body units allows for independent manufacturing and assembly, simplifying the production process. The cone's expansion and contraction parts can be manufactured separately and then assembled, reducing manufacturing complexity.
Solution Approach 2:
The cone serves multiple functions (flow control, sealing, and structural support) through its different parts, reducing the total number of components needed. This multi-functionality simplifies the manufacturing procedure by eliminating the need to produce and assemble multiple separate components for each function.
3Productivity
If the cone reciprocates forward or backward to open or close the flow passage, then the valve can control fluid flow, but turbulence occurs and valve seat abrasion increases
Solution Approach 1:
The cone's expansion part and contraction part are designed with specific local geometries that optimize fluid flow at different positions. The expansion part creates a gradual flow transition to minimize turbulence, while the contraction part directs flow efficiently toward the outlet, reducing overall turbulence and abrasion.
Solution Approach 2:
The conical shape with curved surfaces provides smooth flow transitions compared to sharp edges or flat surfaces. The curved geometry of the expansion and contraction parts reduces flow separation and turbulence, minimizing valve seat abrasion during operation.
4Productivity
If the cone reciprocates forward or backward to open or close the flow passage, then the valve can control fluid flow, but the opening and closing operations are slow
Solution Approach 1:
The cylindrical forward and backward movement unit is designed to enable rapid linear motion of the cone along the axial direction. The dynamic design of the movement unit allows for quick response to actuation signals, enabling fast opening and closing operations while maintaining flow control capability.

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 design simplifies manufacturing and operation, reduces turbulence and valve seat abrasion, and lowers maintenance costs by allowing the cone to reliably open and close the flow passage with fewer components.
Implementation Method 1
a cone (300) which is installed inside a hollow body unit (100) through which fluid flows, wherein since the cone (300) reciprocates forward or backward, a flow passage can be opened or closed
Implementation Method 2
left and right valve inclination surfaces (170, 180) which are inclined corresponding to an inclination surface of the cone (300) and disposed at ends of the left and right bodies (150, 160)
