Mower Protective Cover Retaining Bracket Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mowers face issues with protective cloths flapping and tearing during road transport due to their wide width exceeding maximum permissible vehicle width, leading to uneven folding and potential damage.
Innovation Solution
A mower design featuring adjustable side elements with edge brackets and retaining brackets that pivot and displace to raise the protective cloth, preventing flapping and creasing, and using a retaining strap for stability, allowing the mower to be adjusted from an operating position to a transport position without exceeding vehicle width limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mower width is increased to cultivate fields more economically, then productivity is improved, but the mower exceeds maximum permissible vehicle width for road transport
Solution Approach 1:
The side protective covers are designed to be movable between a working position during mowing operations and a transport position for road travel. This dynamic reconfiguration allows the mower to maintain a wide cutting width for high productivity while complying with road transport width restrictions
Solution Approach 2:
The protective device is divided into modular side elements that can be independently adjusted. Each side element includes an edge bracket and retaining bracket system that can be repositioned to change the overall mower width configuration
2Stability of the object's composition
If the protective cover is tensioned using a pull cord during transport, then the protective flap is prevented from flapping, but the protective flap folds and creases very unevenly and the pull cord can break
Solution Approach 1:
A retaining bracket is introduced as an intermediary component between the edge bracket and the protective cover. This retaining bracket provides a proper attachment point that distributes tension forces evenly across the protective cover, preventing localized stress concentrations that cause creasing and cord failure
Solution Approach 2:
The adjustment mechanism is designed to automatically position the retaining bracket in the holding position when the edge bracket is adjusted to the transport position, eliminating the need for separate manual tensioning operations
3Length of moving object
If the edge bracket is adjusted from operating position to transport position, then the mower width is reduced for road transport, but the protective cover flaps back and forth during transport
Solution Approach 1:
The retaining bracket is designed to dynamically transition from a basic position spaced away from the protective cover to a holding position adjacent to it, automatically engaging to prevent flapping when the mower is in transport configuration
Solution Approach 2:
The adjustment mechanism is designed so that when the edge bracket is moved to the transport position, the retaining bracket is automatically positioned in the holding position in advance, preventing protective cover flapping before transport begins
