Transmission Hoist Conversion for Higher, Stable Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transmission jacks have a high center of gravity, are bulky, and do not elevate high enough, forcing mechanics to bend into awkward positions, which can cause pain and injury, and they occupy significant space in automotive shops.
Innovation Solution
A transmission hoist device that converts an engine hoist into a transmission jack by using a 2″×2″ sleeve that slides onto the engine hoist boom, featuring an adjustable plate and tilt adjustment knobs for securement and angle modification, allowing for higher elevation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional transmission jack is used, then it can support the transmission, but it has a high center of gravity and forces mechanics to bend into awkward positions
Solution Approach 1:
The patent combines the transmission jack functionality with an engine hoist structure into a single integrated device. The hoist assembly includes a hoist motor, boom, and transmission jack components merged together, allowing the transmission to be supported at a higher, more comfortable working elevation while maintaining stability through the hoist's lower center of gravity and wider base.
Solution Approach 2:
The device serves multiple functions: it acts as both an engine hoist for lifting engines and a transmission jack for supporting transmissions. The integrated design allows a single device to perform both functions, eliminating the need for separate tools and providing ergonomic working positions for both types of maintenance work.
2Area of stationary object
If a conventional transmission jack is used, then it can hold the transmission, but it is bulky and occupies significant space in the shop
Solution Approach 1:
By merging the transmission jack with the engine hoist into a single integrated device, the patent reduces the total number of separate tools needed in the shop. The combined device occupies less space than two separate tools would require, while maintaining full transmission support capability through the integrated jack mechanism.
3Length of moving object
If a conventional transmission jack is used, then it can support the transmission, but it does not elevate high enough requiring mechanics to bend over
Solution Approach 1:
The integration of the engine hoist boom with the transmission jack allows the transmission to be elevated to a higher position. The boom structure provides additional height, enabling mechanics to work at a more ergonomic elevation rather than bending over, while the hoist's structural strength maintains support capability.

AI summary
A transmission hoist device is disclosed for converting an engine hoist and a transmission jack into a transmission hoist device. The transmission hoist device comprises a conventional transmission jack with, for example, a 2″×2″ sleeve that slides around a boom of an engine hoist. The steel adapter slides into the arm of the hoist and features an adjustable plate to hold a transmission for removal, repair, and/or replacement. Thus, the transmission hoist device combines a transmission jack and an engine hoist into one convenient tool.
