Reversible Plough Side-Mounted Holder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reversible plows face issues with clogging and contamination due to attachments and fastening areas that project beyond the plow frame, reducing the free passage and increasing the risk of blockages.
Innovation Solution
The functional part holders are attached only to one or two side walls of the plow frame, keeping the areas above and below the frame free of attachments, with screws passing through the frame to avoid contact with wall parts, and using form-fitting attachment elements for secure connection, along with a movable lever for adjusting the working width and absorbing impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If brackets for plow bodies and functional parts are attached to the bottom and top of the plow frame, then the functional parts can be securely mounted, but the free passage between the plow frame and ground surface is reduced, increasing the risk of clogging
Solution Approach 1:
The patent relocates the mounting brackets from the vertical dimension (top and bottom of the plow frame) to the horizontal dimension (side walls of the plow frame). This dimensional shift allows functional parts to be mounted securely while maintaining clear vertical passage between the plow frame and ground surface, thereby eliminating clogging risk without compromising mounting capability.
2Strength
If attachment lugs and fastening areas project beyond the plow frame, then functional parts can be firmly fastened, but the space above and below the plow frame is impaired, significantly increasing clogging risk
Solution Approach 1:
The patent extracts the mounting function from the vertical space (top and bottom areas) and relocates it to the horizontal side walls. By removing the protruding attachment lugs from the critical passage areas, the design maintains strong fastening capability through lateral mounting while completely clearing the vertical passage of obstructions that cause clogging.
3Reliability
If multiple attachment elements are provided on the holder, then the holder can be securely connected to the plow frame, but the complexity of the device increases
Solution Approach 1:
The patent combines multiple attachment functions into a single integrated bracket structure mounted on the side walls. Rather than adding multiple separate attachment elements that would increase complexity, the design uses one well-positioned bracket with inherent mounting features that provides secure connection while maintaining structural simplicity.

AI summary
The plough (1) has plough blade series (4) and plough arms (5) arranged in sides of a plough frame (2) and provided with a plough body (6). The plough body, a supporting wheel (3), a cultivation gantry and/or plough-like functional parts are fastened to the frame by holding units (7). The holding units are fastened to side walls of the frame by functional parts e.g. headstock, of the frame and adjoin to the side walls of the frame in an operative position of the plough. Wall regions of the frame pointing away from the ground are freely formed by the holding units from the functional parts.
