Solution Overview

Problem

Existing centrifugal spreaders face challenges such as manual adjustment difficulties, exposure to grit dust leading to corrosion, complex and time-consuming operation, and high manufacturing costs due to numerous individual parts, making simultaneous adjustment of feed point and dosage quantity cumbersome and costly.

Innovation Solution

The adjusting device and dosing device are connected to a horizontal control panel with a feed point scale on the container's back, allowing for ergonomic operation with fewer steps and reduced exposure to grit, featuring a one-piece metering slide and stop lever, hydraulic, pneumatic, or electrical drive, and a guide shoe for easy assembly and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the adjusting device is arranged near the distribution disk for easy access, then the adjustment operation is convenient, but the adjusting device is exposed to grit dust leading to corrosion

Engineering Contradiction:
Improveadjustment operation convenienceVSAvoidcorrosion resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjusting device is extracted from the area near the distribution disk and relocated to the rear of the spreader where it is not exposed to grit dust. The control panel is positioned at the rear above the distribution disk, allowing operators to adjust settings from a protected location rather than from beneath the distribution disk where corrosion occurs.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the control panel is positioned low for easy access, then the operator can reach it easily, but the operator must bend down causing ergonomic issues and grit exposure

Engineering Contradiction:
Improvecontrol panel accessibilityVSAvoidoperator exposure to grit
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The control panel is repositioned from a low horizontal position to a higher vertical position at the rear of the spreader. This dimensional change allows the operator to remain in an upright position while accessing the controls, eliminating the need to bend down and reducing exposure to upward-spraying grit particles.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple individual parts are used for the adjusting device and dosing device, then the devices can be adjusted independently, but the manufacturing cost increases and assembly becomes time-consuming

Engineering Contradiction:
Improveindependent adjustment capabilityVSAvoidmanufacturing cost and assembly time
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adjusting device and dosing device are merged into a single integrated control panel assembly located at the rear of the spreader. This unified structure combines multiple functions (feed point adjustment and dosage quantity control) into one assembly, reducing the total number of separate parts while maintaining independent adjustability of each function.

Inventive Principle:
Principle #5Merging (Combining)

4Measurement precision

If the feed point and dosage quantity are adjusted separately requiring location changes, then each parameter can be adjusted precisely, but the adjustment process becomes time-consuming

Engineering Contradiction:
Improveparameter adjustment precisionVSAvoidadjustment time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

Both the feed point adjustment mechanism and dosage quantity control mechanism are combined in a single control panel assembly at the rear of the spreader. This allows the operator to adjust both parameters sequentially without leaving the location, maintaining precise adjustment capability while eliminating time loss from moving between adjustment points.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A centrifugal spreader for spreading material, comprising a spreading material container (1) with a funnel-shaped lower section (2) tapering towards a base and at least one discharge opening (9) arranged in the base (4), includes a metering device consisting of a metering plate (11) with a metering opening (10) and a metering slide (18), and an adjustment device (23) for the metering device (10, 11, 18) for repositioning the application point of the spreading material onto a distribution disc equipped with throwing vanes, which rotates below the base (4). The adjustment device (23) and the metering device (10, 11, 18) are operatively connected to a substantially horizontal operating panel (34) for adjusting the application point and the metering quantity, which is guided on a container-fixed application point scale (30, 31) on the rear of the container (1).
