Solution Overview

Problem

Existing soil working machines lack the ability to adjust working depth precisely, accommodate differentiated disc wear, and work effectively across the entire width of the chassis, limiting their operational efficiency and depth adjustment capabilities.

Innovation Solution

The design incorporates multiple rows of oscillating discs with movable disc-carrying beams that allow for independent adjustment of working depth and wear compensation, featuring a system with pivoting supports and actuators for precise axial movement and visual wear indicators for easy adjustment, enabling simultaneous working of the ground by multiple rows during a single pass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple rows of discs are added to increase working width, then productivity increases, but device complexity increases and soil cultivation quality deteriorates due to inability to adjust depth independently

Engineering Contradiction:
Improveworking widthVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The machine divides the disc system into multiple independent rows, each with its own adjustable beam. This segmentation allows each row to be controlled independently for depth adjustment while maintaining overall system manageability despite increased complexity from multiple rows

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements movable beams that can dynamically adjust their position vertically to control disc depth. Each beam is equipped with adjustment mechanisms allowing real-time depth modification during operation, transforming a static structure into a dynamic, adaptable system

Inventive Principle:
Principle #15Dynamics

2Reliability

If disc wear varies between rows, then reliability deteriorates, but adjustment capability is limited in known machines

Engineering Contradiction:
Improvedisc wear compensationVSAvoiddepth adjustment capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by allowing each row's beam to be adjusted independently based on local wear conditions. Each row can have its depth customized to compensate for specific wear patterns in that area, rather than requiring uniform adjustment across all rows

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system enables parameter changes by allowing independent modification of the vertical position parameter for each beam. This changes the operational parameters of each row to compensate for wear, maintaining consistent cutting depth despite varying disc conditions

Inventive Principle:
Principle #35Parameter changes

3Productivity

If working depth is increased for better soil cultivation, then productivity improves, but ease of operation deteriorates due to lack of precise adjustment

Engineering Contradiction:
Improvesoil cultivation qualityVSAvoiddepth adjustment precision
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by providing adjustment mechanisms that allow depth to be set and optimized before operation begins. The beams can be pre-adjusted to the required depth positions, ensuring optimal soil cultivation from the start of operation

Inventive Principle:
Principle #10Preliminary action
