Portable SUV Hardtop Removal Device with Pedal Lift Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing and installing SUV hardtops are cumbersome, requiring multiple people due to their weight and size, and are not portable, making them unsuitable for owners without a garage or for use outside their home, especially with newer models like the Jeep Gladiator that present unique removal challenges.
Innovation Solution
A portable device with a wheeled base unit, vertical support structure, and top frame assembly, featuring a ball-style coupler for swiveling and adjustable casters, along with a pedal lift mechanism for easy lifting and locking, allowing single-user operation and side or front removal and storage of hardtops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed overhead lift is used to remove and install hardtops, then the hardtop removal and installation process is simplified, but the device requires a garage or support structure and is not portable
Solution Approach 1:
The device employs a movable platform that can be positioned at different locations along the vehicle and adjusted to various heights, transforming the static overhead lift into a dynamic, adaptable system that maintains ease of operation while enabling portability and versatility across different environments including garages, driveways, and camping locations
2Weight of moving object
If a group of four people is used to lift and remove or install a removable hardtop, then the weight load is shared, but the process becomes more complex and time-consuming
Solution Approach 1:
The device incorporates a lifting mechanism with mechanical advantage that enables a single operator to lift and position the heavy hardtop independently, eliminating the need for multiple people and reducing operational complexity while effectively managing the weight load through engineered mechanical assistance
3Ease of operation
If a fixed position lift device is used, then the hardtop can be removed and installed, but the vehicle cannot be parked in the garage while the hardtop is affixed to the device
Solution Approach 1:
The movable platform can be repositioned along the vehicle and adjusted to different heights, allowing the vehicle to remain accessible and parkable in the garage while the hardtop is affixed to the device, eliminating the restriction imposed by fixed position lift devices
