Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines have a large angle between the machine body and the horizontal plane, making them prone to collisions with objects when cleaning areas such as below low cabinets.
Innovation Solution
A push-pull connection mechanism is introduced, featuring a rotating member and a first connecting member with a rotation axis parallel to the machine body's axis, allowing for controlled movement of the machine head in different directions and reducing the angle between the machine body and the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional connection structure is used to connect the machine body and machine head, then the connection is simple and robust, but the angle between the machine body and horizontal plane becomes large, causing collisions with objects in tight spaces
Solution Approach 1:
The connection structure is divided into multiple functional segments: a rotating member on the machine head, a first connecting member with parallel rotation axis, and a second connecting member with perpendicular rotation axis. This segmentation allows independent control of different rotational degrees of freedom, enabling the machine body to maintain a small angle with the horizontal plane while the machine head can be precisely oriented, thus improving maneuverability in tight spaces without excessive structural complexity.
Solution Approach 2:
The connection structure incorporates dynamic rotational capabilities through two distinct rotation axes. The first connecting member rotates parallel to the machine head's rotation axis, while the second connecting member rotates perpendicularly. This dynamic configuration allows the operator to adjust the machine head's orientation independently from the machine body's angle relative to the floor, enabling operation in tight spaces with low clearance while maintaining cleaning effectiveness.
2Object-affected harmful factors
If the angle between machine body and horizontal plane is reduced for better access to low areas, then collision risk decreases, but control precision over machine head direction becomes difficult
Solution Approach 1:
The connection structure employs asymmetric rotational arrangements with two distinct rotation axes at different orientations. The first connecting member's rotation axis is parallel to the machine head's rotation axis, while the second connecting member's rotation axis is perpendicular. This asymmetric design allows the machine body to be positioned at a low angle for accessing tight spaces while the machine head can be independently oriented with high precision through the dual-rotation mechanism, thus reducing collision risk without sacrificing directional control.
Solution Approach 2:
The first and second connecting members act as intermediary elements between the machine body and machine head. These intermediaries provide the necessary rotational degrees of freedom, allowing the machine body to maintain a small angle with the horizontal plane for safe operation in tight spaces, while simultaneously enabling precise control of the machine head's direction through coordinated rotation of the connecting members.
3Adaptability or versatility
If the machine body is positioned at a small angle to the floor for cleaning low areas, then accessibility improves, but the structural stability and force transmission may be compromised
Solution Approach 1:
The connection structure introduces an additional rotational dimension through the second connecting member, whose rotation axis is perpendicular to the first connecting member's axis. This dimensional addition allows the machine body to be positioned at a small angle to the floor for accessing low areas, while the machine head can be independently oriented through rotation in the perpendicular dimension, thereby maintaining structural stability and proper force transmission geometry even when the machine body is at a low operating angle.

AI summary
A push-pull connection mechanism for a floor cleaning machine, and a floor cleaning machine. The push-pull connection mechanism comprises: a rotating member rotatably mounted on a machine head; and a first connecting member rotatably mounted on the rotating member by means of a rotating shaft, a rotation axis of the first connecting member being parallel to a rotation axis of the rotating member. A machine body rotatably matches the first connecting member, and a rotation axis of the machine body is perpendicular to the rotation axis of the first connecting member. The rotation axis of the first connecting member of the push-pull connection mechanism is parallel to the rotation axis of the rotating member, i.e., eccentric arrangement is performed, so that an operator can control the machine head to move in different directions by applying forward, backward, leftward, and rightward force to the machine body.
