Hoist-it Engine Removal System for Solo Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lifts and engine hoists require multiple individuals for operation and occupy significant space, making them expensive and inefficient for single-person use in repair facilities.
Innovation Solution
A hoist system with vertically positioned supports and a horizontal member, equipped with winches and chain drives, allowing a single individual to lift and remove vehicle engines by securing the hoist to the engine and using a winch to lift it from the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle lift and engine crane-hoist are used to remove an engine, then the engine can be removed from the vehicle, but two or more individuals are required to operate the equipment
Solution Approach 1:
The patent combines the vehicle lift and engine crane-hoist into a single integrated hoist system. The hoist includes a horizontal member with vertical supports that can both lift the vehicle and position the engine, eliminating the need for separate equipment and multiple operators. This merging of functions allows one individual to perform tasks that previously required two or more people.
2Productivity
If a vehicle lift and engine crane-hoist are used, then engine removal is enabled, but significant space is required for mounting and positioning the equipment
Solution Approach 1:
The hoist system is designed to perform multiple functions within a single compact structure. The horizontal member with vertical supports can function as both a vehicle lift and an engine positioning device. The winch system can lift both the vehicle and the engine, eliminating the need for separate dedicated spaces for vehicle lifts and engine cranes, thereby reducing the overall facility space requirement.
3Productivity
If separate vehicle lift and engine crane-hoist are used, then engine removal is possible, but the equipment is expensive to purchase and accommodate
Solution Approach 1:
The patent integrates the vehicle lift and engine crane-hoist into a single hoist system with a horizontal member, vertical supports, and winch mechanism. This consolidation reduces the number of separate expensive pieces of equipment needed, lowering both purchase and maintenance costs while maintaining full engine removal capability.
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
Enables a single person to safely and efficiently remove vehicle engines, reducing space requirements and operational costs by allowing solo operation and flexible positioning of the hoist.
Implementation Method 1
a cable 40C having a second end connected to the hook 24... permitting the hook 24 to be raised vertically a predetermined distance
Implementation Method 2
A first chain drive 18C is positioned within the first substantially vertical support 12 for raising the first vertical lift 18... A second chain drive 19C is positioned within the second substantially vertical support 13 for raising the second vertical lift 19

AI summary
A hoist for removing an object to enable an individual to work on the object includes a first substantially vertical support mounted on a floor surface. A second substantially vertical support mounted on the floor surface and being spaced a predetermined distance away from the first substantially vertical support. The first and second substantially vertical supports include an upper surface. A substantially horizontal member extending across the upper surfaces of the first and second substantially vertical supports. A first vertical lift is operatively positioned within the first substantially vertical support. A second vertical lift is operatively positioned within the second substantially vertical support. The first and second vertical lifts selectively raising the member relative to the floor surface. A winch is operatively mounted on the substantially horizontal member for lifting the object relative to the member for enabling an individual to work on the object.
