Self-Contained Jettison Means for Demountable Vehicle Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-based jettison systems for implements have limitations, particularly in allowing for efficient detachment and replacement of damaged or obsolete equipment, as they rely solely on vehicle-mounted mechanisms, which can be complex and costly.
Innovation Solution
The implement is equipped with self-contained jettison means, such as close-fitting pins and wedges, which can be hydraulically, electrically, or pneumatically operated, allowing it to be detached from the vehicle without requiring onboard jettisoning capabilities, enabling easy replacement or change of implements like bulldozer blades, rollers, or mine ploughs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle-based jettison system is provided, then the vehicle can eject implements, but the system becomes complicated and expensive
Solution Approach 1:
The implement is equipped with its own jettison means (pins, wedges, or other release mechanisms) that enable it to be detached from the vehicle independently. The implement essentially serves itself by providing the detachment functionality rather than relying on the vehicle's systems.
Solution Approach 2:
Instead of the vehicle providing the jettisoning capability (vehicle-based system), the invention inverts the approach by placing the jettison means on the implement itself. This reverses who provides the detachment function - the implement rather than the vehicle.
2Ease of operation
If a vehicle-based jettison system is provided, then the vehicle can eject implements, but the cost increases
Solution Approach 1:
The implement is equipped with its own jettison means (pins, wedges, or other release mechanisms) that enable it to be detached from the vehicle independently. The implement essentially serves itself by providing the detachment functionality rather than relying on the vehicle's systems.
Solution Approach 2:
The jettison means on the implement (such as pins or simple mechanical release mechanisms) are simpler and less expensive compared to a full vehicle-based jettison system. The implement can be designed with these simpler, more cost-effective detachment components.
3Adaptability or versatility
If the implement has self-contained jettison means, then the implement can be detached independently, but the implement structure becomes more complex
Solution Approach 1:
The jettison function is segmented into separate components (pins, wedges, or other release mechanisms) that are distinct from the main implement structure. This allows the detachment functionality to be added as modular elements rather than integrating complexity throughout the entire implement.
Solution Approach 2:
The jettison means are localized to specific positions on the implement (such as at the mounting interface with the vehicle) rather than being distributed throughout the entire structure. This concentrates the added complexity only where needed for detachment functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables a family of interchangeable, jettisonable implements that can be selectively mounted or demounted from a vehicle, reducing the need for separate lifting equipment and allowing for efficient maintenance and task adaptation by providing the jettisoning functionality directly on the implement, thereby simplifying operations and reducing costs.
Implementation Method 1
The jettison means may be at least partly hydraulically and/or electrically and/or pneumatically and/or explosively operated. A hydraulic power pack may, for example, be provided on or by the implement.
Implementation Method 2
The pins (which may be close-fitting) may be intended to be fitted into pin receivers, such as lugs with holes, provided on a vehicle.
Implementation Method 3
In some embodiments the pins may be used in conjunction with wedges, abutments or the like to hold the implement in place. In this type of system the wedges hold the implement in position
