Solution Overview
Problem
Existing surface-treatment appliances, such as scrubbing suction machines, face challenges in providing improved handling capabilities, particularly in accessing and cleaning difficult-to-reach surface regions, due to limited movement range and undesirable force influences on the base arrangement.
Innovation Solution
The introduction of an arcuate guide on the base arrangement, which supports a carriage body with at least two spaced-apart supporting points, allowing for linear displacement and improved pivoting capability, enabling easier and more precise control of the guide part, thereby enhancing handling and reducing undesirable force influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide part is rigidly connected to the base arrangement, then structural simplicity is maintained, but handling capability and access to difficult-to-reach areas are limited
Solution Approach 1:
The connection between the guide part and base arrangement is segmented into multiple independent components: the arcuate guide, carriage body, and guide part. This segmentation allows each component to perform its specific function while improving overall handling capability through independent movement capability.
Solution Approach 2:
The connection is made dynamic through the arcuate guide and carriage body mechanism, which allows the guide part to pivot and move relative to the base arrangement. This dynamic connection adapts to different operational requirements while maintaining structural integrity.
2Adaptability or versatility
If the guide part is rigidly connected to the base arrangement, then manufacturing simplicity is maintained, but pivoting range and access to hard-to-reach areas are limited
Solution Approach 1:
The arcuate guide employs a curved geometry instead of a straight rigid connection. This curvature enables the guide part to pivot through a wide angle range while maintaining a compact structure that is relatively simple to manufacture using standard curved profile extrusions or bent metal sections.
Solution Approach 2:
The pivoting motion is achieved by moving the guide part along the arcuate path, effectively adding a rotational degree of freedom in a different dimension rather than requiring complex multi-axis mechanisms.
3Ease of operation
If forces are applied to the guide part for manual control, then positioning capability is achieved, but undesirable moments and forces are transmitted to the base arrangement
Solution Approach 1:
The carriage body acts as an intermediary between the guide part and the arcuate guide. It receives and transmits forces in a controlled manner, allowing manual positioning forces to be applied to the guide part while filtering out undesirable moments from reaching the base arrangement through the arcuate guide's geometric constraints.
Solution Approach 2:
The undesirable pitching moments and force components are extracted or isolated from the force transmission path. The arcuate guide geometry and carriage body support structure selectively transmit only the useful positioning forces while preventing the transmission of harmful moments to the base arrangement.

AI summary
Surface-treatment appliance having a base arrangement, which in a functional position can be displaced on a surface which is to be treated, and having a guide part articulated on the base arrangement and intended for controlling the base arrangement manually. An arcuate guide is provided on the base arrangement, on which can be displaced in a linear manner a carriage body. The carriage body is connected to the guide part and is supported on the arcuate guide, at least in the radial direction, by at least two supporting points, which are spaced apart from one another along the arcuate guide.
