Solution Overview

Problem

Existing air seeders and fertilizer spreaders face complex linkage systems requiring disassembly and rotation of diverter valves for routing adjustments, leading to inefficiency and potential air leakage due to incorrect internal partitioning.

Innovation Solution

A spring-loaded outlet selector valve with a divider plate and parallel springs allows easy manual adjustment of the valve position without tools, ensuring air and product flow direction through an inverted 'Y'-shaped housing, preventing air leakage and simplifying operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex linkage system with common actuating rod is used to control diverter valves, then the valves can be linked together for routing adjustments, but the system requires disassembly and rotation of multiple components, increasing operation time and complexity

Engineering Contradiction:
Improverouting adjustment capabilityVSAvoidlinkage system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the routing control into independent sectional valves, each controlled by its own actuator. This segmentation eliminates the need for a complex common linkage system, allowing each valve to be adjusted independently without disassembling or rotating other components, thus reducing operational complexity while maintaining routing versatility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs adjustable and repositionable diverter valves that can be dynamically reconfigured. The valves are designed to be rotated and repositioned to different angular positions (e.g., 0°, 45°, 90°, 135°) to achieve different routing configurations, providing adaptability without requiring a fixed complex linkage system

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple diverter valves are linked together with a common actuating rod, then routing can be adjusted, but the operation requires extra effort and time for disassembly and rotation

Engineering Contradiction:
Improverouting configuration flexibilityVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

By segmenting the control system into independent valves with individual actuators, the patent eliminates the time-consuming disassembly and rotation operations required by linked systems. Each valve can be quickly adjusted independently, significantly reducing the total time for routing reconfiguration

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The diverter valves are designed with self-contained adjustment mechanisms that allow operators to reconfigure routing without requiring disassembly or complex manipulation. The valves can be directly rotated to desired positions, enabling operators to perform routing adjustments themselves without needing to disassemble linked components

Inventive Principle:
Principle #25Self-service

3Reliability

If internal partitions are not correctly positioned in the linkage system, then routing adjustment is difficult, but air leakage continues to occur

Engineering Contradiction:
Improveair tightnessVSAvoidinternal partition positioning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses multiple independent sectional valves instead of a single complex linkage system with internal partitions. Each valve independently controls its section, eliminating the difficulty of positioning internal partitions while maintaining air tightness through proper valve sealing mechanisms

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent incorporates visual indicators (such as colored markers or position indicators) on the diverter valves to show their current angular position and routing configuration. This makes it easy for operators to verify correct positioning and ensures air-tight sealing by preventing operation when partitions are misaligned

Inventive Principle:
Principle #32Color changes
