Adjustable Lifting Device for Motor Vehicle Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for motor vehicle assemblies, such as transmissions and engines, lack adaptability to different vehicle types, requiring multiple devices for various assemblies and increasing storage space needs in workshops.
Innovation Solution
A lifting device with a longitudinally movable coupling unit and an adjustable load carrying unit connected to a crane or hoist unit, allowing for tiltable and pivotable support arms to accommodate various motor vehicle assemblies, eliminating the need for multiple assembly-specific lifting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lifting device is designed for a specific motor vehicle assembly type, then it can reliably remove that assembly, but it cannot adapt to different assembly types requiring multiple devices
Solution Approach 1:
The lifting device is divided into modular components: a base unit with hoist mechanism and interchangeable support arms. Each support arm can be detached and replaced based on the specific assembly type, allowing the device to adapt to different motor vehicle assemblies without redesigning the entire system.
Solution Approach 2:
The base unit is designed with universal mounting interfaces and adjustment mechanisms that can accommodate multiple types of support arms. This multi-functional design allows a single base unit to serve various lifting applications by simply changing the support arm configuration.
2Adaptability or versatility
If multiple lifting devices are kept for different assembly types, then all assembly removal tasks can be covered, but storage space requirements increase
Solution Approach 1:
Multiple support arms are stored in a nested configuration within the base unit when not in use. The support arms can be collapsed or stacked inside the base structure, significantly reducing the storage volume compared to keeping multiple separate lifting devices.
3Adaptability or versatility
If the coupling unit is fixed on the support arm, then the structure is simple, but it cannot be adjusted to different positions for different assemblies
Solution Approach 1:
The coupling unit is designed with movable and adjustable features, including sliding mechanisms and pivot joints that allow it to be repositioned along the support arm. This dynamic design enables the coupling unit to adapt to different mounting positions required by various assembly types.

AI summary
A lifting device is provided for an assembly of a motor vehicle that can be adapted to lift various assemblies. The lifting device includes a load carrying unit having at least one support arm, and a coupling unit arranged on the support arm for releasably connecting the support arm to the assembly of a motor vehicle. The lifting device can be used as an engine hoist and/or a transmission hoist for removing and installing engines and/or transmissions and can be used to remove a wide range of assemblies, at least different engines and/or transmissions of different types of vehicles. The coupling unit is mounted on the support arm in a longitudinally movable manner. The load carrying unit is designed to be connected to a crane unit, and in particular has a crane hook holder, and/or is adjustably connected to a support unit arrangeable on a hoist unit.
