Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed drills face challenges in efficiently and easily transitioning between working and maintenance positions, requiring complex hydraulic or pneumatic mechanisms, which can be cumbersome and limit access to components.
Innovation Solution
A sowing unit with a collapsible quadrangle or double quadrangle tilting mechanism that connects the frame to the chassis, allowing the frame to move between lowered and raised positions without hydraulic or pneumatic assistance, providing stable access and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic or pneumatic mechanisms are used to move the frame between working and maintenance positions, then the frame can be moved reliably, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent removes hydraulic or pneumatic assistance systems from the frame tilting mechanism, extracting the complex powered components while retaining the essential tilting function through a simplified mechanical linkage system consisting of links and pivots
Solution Approach 2:
The frame tilting mechanism is designed to be manually operable through mechanical links and pivots, allowing operators to move the frame between working and maintenance positions without requiring external hydraulic or pneumatic power systems
2Ease of operation
If hydraulic or pneumatic mechanisms are used to move the frame, then the frame can be moved between positions, but the ease of operation decreases due to complexity
Solution Approach 1:
The patent removes hydraulic or pneumatic assistance systems from the frame tilting mechanism, extracting the complex powered components while retaining the essential tilting function through a simplified mechanical linkage system consisting of links and pivots
Solution Approach 2:
Instead of using powered systems to force the frame into position, the mechanism uses gravity and mechanical advantage through links and pivots to allow the frame to tilt naturally between positions, inverting the approach from active powered movement to passive mechanical guidance
3Ease of repair
If complex hydraulic or pneumatic mechanisms are used, then the frame can be moved between positions, but maintenance accessibility is limited
Solution Approach 1:
The patent removes hydraulic or pneumatic assistance systems from the frame tilting mechanism, extracting the complex powered components while retaining the essential tilting function through a simplified mechanical linkage system consisting of links and pivots
Solution Approach 2:
The tilting mechanism is divided into discrete mechanical links and pivots that can be independently accessed and maintained, with the frame itself being movable between working and maintenance positions to provide access to components

AI summary
Systems and methods for distributing granular products onto or into the soil, comprising a chassis, a first assembly for distributing a first granular product comprising a main hopper, fixed to a frame, which can move in relation to said chassis and is able to adopt a position known as the “lowered” position, which is the working position of said sowing unit, and a position known as the “raised” position, which is the maintenance position of said sowing unit, and that is able to move from said “lowered” position to said “raised” position and vice versa, said sowing unit also comprising a mechanism for tilting said frame and comprising a collapsible quadrangle or double quadrangle that connects said frame to said chassis, said tilting mechanism being arranged substantially perpendicular to the plane X-X′ formed by said chassis, and maintained substantially perpendicular to said plane X-X′in said “lowered” and “raised” positions and when moving from one position to the other, and vice versa. The systems may include a seed drill comprising one or more sowing units.
