Removable SUV Door Handling Device with Wheeled Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Removable SUV doors are heavy and unwieldy, making them difficult for a single person to install or remove, especially for disabled individuals or those with limited strength, and existing solutions often damage the doors or pose injury risks.
Innovation Solution
A wheeled base unit with adjustable casters and a U-shaped vertical frame that supports multiple doors, featuring door slots and a top clamp system to immobilize and secure doors during removal and storage, allowing for efficient handling and storage of multiple doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If removable SUV doors are designed to be safety-driven and heavy, then door strength and safety are improved, but ease of operation deteriorates as single persons struggle to hold and maneuver the heavy doors
Solution Approach 1:
The patent introduces a door holding device as an intermediary tool between the operator and the heavy door. This device includes a base unit with a door holding structure that can support the door's weight, allowing the operator to work with the door without directly bearing its full weight. The holding structure comprises a holding surface and a clamping mechanism that secures the door in place during installation or removal operations.
2Ease of operation
If overhead lifts or pulleys are used to aid door removal, then ease of operation is improved, but device complexity and risk of damage or injury increase due to ungainly structures
Solution Approach 1:
The door holding device is segmented into distinct functional components: a base unit providing stability, a door holding structure with a holding surface for supporting the door, and a clamping mechanism for securing the door. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure simple and manageable, avoiding the complexity of overhead lifts or pulleys.
3Ease of operation
If a structure is used to support door weight during removal, then ease of operation is improved, but floor space requirements increase
Solution Approach 1:
The door holding device incorporates a mobile base unit with casters or wheels, transforming it from a static structure to a dynamic, movable system. This allows the device to be easily repositioned around the vehicle as needed and stored in a compact space when not in use, minimizing floor space requirements while maintaining its door-supporting function during operation.
