Solution Overview

Problem

Existing agricultural tillage devices face challenges in adjusting the throwing angle of skimmers due to complex and error-prone mechanisms, leading to unintentional changes in working parameters and reduced work quality, especially under varying environmental conditions.

Innovation Solution

A carrier device with two carrier bodies that change their longitudinal rotation angle relationships between two assembly positions, eliminating the need for additional components like wedges or complex adjusting devices, simplifying the throwing angle adjustment and reducing maintenance and manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an adjustment device with connecting rods and lever arms is used to adjust the throwing angle of skimmers, then the throwing angle can be adjusted, but the device complexity increases due to the large number of moving components

Engineering Contradiction:

Improvethrowing angle adjustmentVSAvoidnumber of moving components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex adjustment device (connecting rods, lever arms, multiple joints) from the skimmer assembly. Instead, it uses a simple longitudinal rotation of the carrier body relative to the plough body to achieve throwing angle adjustment, removing unnecessary moving components while preserving the adjustment function.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a complex mechanism to actively adjust the throwing angle through multiple moving parts, the invention inverts the approach by using a simple rotational degree of freedom of the carrier body. The adjustment is achieved passively through the relative longitudinal rotation between carrier body and plough body, rather than through an active adjustment mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If an adjustment device with multiple components is used to adjust the throwing angle of skimmers, then the throwing angle can be adjusted, but the susceptibility to errors and failures increases due to wear and contamination of mechanical components

Engineering Contradiction:

Improvethrowing angle adjustmentVSAvoidsusceptibility to errors and failures

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent removes the vulnerable mechanical adjustment components (joints, connecting rods, lever arms) that are susceptible to wear and contamination. The throwing angle adjustment is achieved through the inherent longitudinal rotation capability of the carrier body, eliminating parts that could fail due to mechanical wear or soil contamination.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If an adjustment device with additional components is used to adjust the throwing angle of skimmers, then the throwing angle can be adjusted, but the manufacturing and maintenance costs increase

Engineering Contradiction:

Improvethrowing angle adjustmentVSAvoidmanufacturing and assembly costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention extracts and eliminates the need for separate adjustment device components (wedges, clamps, bolts, connecting rods). The throwing angle adjustment functionality is integrated into the basic carrier body structure through its longitudinal rotation capability, reducing manufacturing steps and assembly operations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The carrier body's longitudinal rotation capability serves multiple functions: it provides the throwing angle adjustment while also serving as the basic mounting structure for the skimmer. This multi-functionality eliminates the need for separate adjustment mechanisms, reducing both manufacturing and assembly costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If an adjustment device with additional components is used to adjust the throwing angle of skimmers, then the throwing angle can be adjusted, but the maintenance work becomes more difficult

Engineering Contradiction:

Improvethrowing angle adjustmentVSAvoidmaintenance work

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The patent removes all adjustment components that would require maintenance (wedges, clamps, bolts, connecting rods, lever arms). The throwing angle is adjusted through the simple longitudinal rotation of the carrier body, which has no moving parts requiring lubrication, tightening, or replacement.

Inventive Principle:

Principle #2Taking out (Extraction)
