Rotatable Disc Lifting Frame for Stable Underside Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices are limited in their applications due to their design, which restricts flexibility in handling different types of bodies and locations of use.
Innovation Solution
The lifting device incorporates a holding element with at least one rotatably mounted support element, allowing the body to be rotated even when lifted, and a pivot bearing and drive device for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the holding element is positioned close to the base element, then the tilt angle can be kept smaller and stability improved, but accessibility to the underside of the holding element and the lifted body is insufficient
Solution Approach 1:
The patent introduces a vertical dimension through the rod connection, positioning the holding element at a different vertical level from the base element. This spatial separation in the vertical dimension allows the bearing plane to be vertically spaced from the base element, simultaneously achieving small tilt angles for stability and sufficient clearance for accessibility to the underside of the holding element and lifted body.
2Stability of the object's composition
If the holding element securely encompasses the disc-shaped body, then lateral tipping is prevented, but rotational mobility of the body is restricted
Solution Approach 1:
The patent applies dynamics by making the support elements rotatably mounted on the holding element rather than fixed. This allows the support elements to rotate along with the disc-shaped body, maintaining secure lateral support while enabling free rotational movement. The rotational capability is achieved through pivot bearings that allow the support elements to follow the body's rotation.
3Ease of operation
If the lifting device is designed with a larger tilt angle for better accessibility, then the underside is more accessible, but the stability of the supported body decreases
Solution Approach 1:
The patent resolves this contradiction by utilizing the vertical dimension through the rod connection. The rod creates a vertical offset between the base element and the holding element's bearing plane, allowing the holding element to be positioned such that it provides both accessibility (through vertical spacing) and stability (through small tilt angles). This vertical dimension separation enables simultaneous achievement of both requirements.
