Tipping arrangement of a movable cleaning unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning units require significant user force and awkward lifting positions to empty containers, with previous solutions either necessitating container lift or requiring sturdy base units to act as counterweights, and often failing to reduce initial pivoting force effectively.
Innovation Solution
A tipping arrangement featuring a movable base unit and rotatable container with a track system where a second element moves along a first track, shifting the pivot point towards the container's center of gravity, reducing the force needed to rotate the container and providing a stable emptying process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is pivotally mounted to the base unit to allow emptying by pivoting, then the container can be emptied without lifting, but the user must apply a large amount of force at the beginning to pivot the container
Solution Approach 1:
The base unit is designed to function as a counterweight to the container during the emptying process. The base unit's weight and positioning create a balancing effect that reduces the initial force required to pivot the container, allowing the container to rotate more easily around the pivot point.
Solution Approach 2:
The invention introduces a tipping arrangement that adds a rotational dimension to the emptying process. Instead of simple lifting or linear movement, the container rotates around a pivot point located at the lower end of the base unit, creating a tipping motion that leverages gravity and reduces required input force.
2Force
If the base unit acts as a counterweight for the container during emptying, then the pivoting force is reduced, but the base unit and mounting structure must be very sturdy to carry the weight
Solution Approach 1:
The base unit serves as a counterweight that balances the container's weight during emptying. By positioning the pivot point at the lower end of the base unit and utilizing the base unit's mass, the system creates a leveraged balancing effect that reduces structural stress while maintaining the ability to support the container.
3Ease of operation
If the container is lowered to the ground and removed from the support structure to empty it, then awkward lifting positions are avoided, but the container still requires lifting to empty
Solution Approach 1:
The invention transforms the emptying operation from vertical lifting to rotational tipping. The container rotates around a pivot point located at the lower end of the base unit, creating a tipping motion that allows contents to pour out without requiring the user to lift the container vertically or assume awkward lifting positions.

AI summary
A tipping method for a tipping arrangement which includes a first element (1) and a second element (2), arranged between a moveable base unit (4) and a rotatable container (3). The container (3) is rotated by moving the second element (2) along a first track (7) on the first element (1). The second element (2) is moved along the track (7) by rotating the second element (2) relative to the first element (1). A number of engaging parts (9, 10) may be arranged on the tracks (7, 8) of the elements (1, 2), respectively. An interlocking arrangement may be arranged between the first element (1) and the second element (2) to secure the second element (2) in a starting position. A movable unit includes the tipping arrangement and a section unit, with the container (3) locked in a vertical position by a locking arrangement.
