Vehicle Hoist Winch With Adjustable Boom Support Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoisting systems for all-terrain vehicles lack the ability to drag loads to the vehicle, have fixed boom height and angle, are not compatible with dumping beds, and lack electrical winch operation, limiting their functionality in retrieving and lifting heavy loads, especially in remote locations.
Innovation Solution
A hoist assembly with a motor-driven winch, a rotatable boom, and adjustable boom support cable that allows for variable boom height and angle, enabling the system to drag, lift, and place loads into a vehicle's cargo area, with the winch positioned near the front end for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed boom height and angle system is used, then the device structure is simple, but the adaptability to different loading positions is poor
Solution Approach 1:
The boom is designed with variable height and angle capabilities through hydraulic cylinders and telescopic sections, allowing dynamic adjustment to different positions. This enables the system to adapt to various loading scenarios while maintaining a manageable structural complexity through modular design.
Solution Approach 2:
The system changes physical parameters of the boom including height, angle, and extension length to accommodate different loading positions. These parameter adjustments are achieved through hydraulic actuation and telescopic mechanisms that modify the boom's geometric configuration.
2Adaptability or versatility
If the winch is attached to the boom, then the lifting function is achieved, but the dragging function to pull loads to the vehicle is not provided
Solution Approach 1:
The winch system is designed to perform multiple functions including both dragging loads horizontally to the vehicle and lifting loads vertically. This multi-functionality is achieved by coordinating the winch cable system with the boom's variable positioning capabilities, allowing a single integrated system to replace what would otherwise require separate dragging and lifting devices.
Solution Approach 2:
The dragging and lifting functions are merged into a single integrated system where the winch, boom, and cable work together. The winch cable can first drag the load horizontally along the ground, then as the boom extends and positions itself, the same cable system transitions to lifting the load vertically, combining two distinct operations into one unified mechanism.
3Productivity
If the winch lifts only the weight and not the boom, then the system is simpler, but the productivity is reduced due to sequential operations
Solution Approach 1:
The boom lifting mechanism and load lifting mechanism are merged into a single coordinated system. The hydraulic system that raises the boom simultaneously supports the load through the cable system, eliminating the need for separate sequential operations. This integration allows the boom and load to be lifted together, significantly improving loading productivity.
Solution Approach 2:
The system maintains continuous useful action by coordinating the boom elevation with the load lifting process. As the boom is raised, the cable system continuously supports and elevates the load without interruption or idle periods. This continuous operation eliminates the downtime that would occur if the boom were positioned first and then the load was lifted separately.
4Adaptability or versatility
If the hoist assembly is located at the rear or side of the vehicle, then the structure is simpler, but it is not compatible with the use of a dumping bed
Solution Approach 1:
The hoist assembly is positioned at the front of the vehicle with the boom extending over the dumping bed, creating a localized functional arrangement optimized for bed compatibility. This front-mounted configuration allows the boom to clear the bed while the winch and control systems remain accessible, providing local adaptation that enables dumping bed operation without requiring a complete redesign of the entire system.

AI summary
A hoist assembly having a winch with a motor, a boom that rotates upward and downward, and a boom support cable which prevents the boom from rotating downwards below a desired level. The boom support cable is connected to an adjustment bar which adjusts the length of the boom support cable to fix the boom position at a desired angle. Alternatively, a boom hook can be used to fix the boom position at a desired angle. The winch and boom are attached at a front end of a cargo receiving area of a vehicle and are constructed to retrieve a load to the vehicle, lift the load, and place the load into the cargo receiving area. The winch is constructed to lift both the load and the boom simultaneously.
