Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld floor cleaners face issues with torque transmission flexibility and synchronicity due to the need for multiple hinged components, leading to increased part count and cost, and inefficient cleaning direction control.
Innovation Solution
A simplified design with a guide part and bottom part connected via a guide member and connecting part, forming hinge axes for flexible torque transmission without eccentricity, using either circular connecting structures or a ball-groove connection, allowing synchronous rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a double vertical hinge connecting member is used to connect the guide part and bottom part, then the cleaner can achieve flexible steering control, but the number of components increases and the cost increases
Solution Approach 1:
The patent merges the guide member and connecting part into a single integrated component that directly connects the guide part and bottom part. This integrated structure eliminates the need for separate double vertical hinge connecting members, reducing component count while maintaining the ability to achieve flexible steering control through direct connection with formed hinge axes.
Solution Approach 2:
The guide member and connecting part serve multiple functions simultaneously: they provide structural connection between guide part and bottom part, form hinge axes for rotation, enable torque transmission, and allow steering control. This multi-functionality replaces what previously required multiple specialized components.
2Ease of operation
If a double vertical hinge connecting member is used to connect the guide part and bottom part, then the cleaner can achieve flexible steering control, but the cost increases
Solution Approach 1:
By combining the guide member and connecting part into one integrated component, the patent reduces the total number of parts that need to be manufactured, assembled, and inventoried. This directly lowers manufacturing costs while maintaining steering control flexibility through the direct connection design.
3Stability of the object's composition
If multiple hinged components are used for connection, then the cleaner can achieve rotation, but the torque transmission is not synchronous and flexible due to eccentric point transmission
Solution Approach 1:
The patent extracts and eliminates the intermediate hinged components that caused eccentric torque transmission. By using a direct connection between the guide member and connecting part, the design removes the problematic intermediate elements while preserving the essential rotation capability through directly formed hinge axes.
Solution Approach 2:
The direct connection structure acts as an ideal intermediary that enables synchronous torque transmission between the guide part and bottom part. By eliminating multiple hinged components, the connection becomes a direct mediator that transmits torque without eccentricity, improving synchronicity and flexibility.

AI summary
Provided is a handheld floor scrubber, comprising a guide part (1) and a base part (2); the guide part (1) has a guide portion (106), and the base part (2) has a connecting portion (201), the guide part (1) and the base part (2) being directly connected by means of the guide portion (106) and the connecting portion (201); the guide part (1) and the base part (2) jointly achieve adjustment in a cleaning direction and in a direction perpendicular to the cleaning direction; the guide portion (106) and the connecting portion (201) are directly connected and then have a hinge axis (G1) in the cleaning direction and a hinge axis (G2) crossing the cleaning direction. In the handheld floor scrubber, the two rotating parts are simply and efficiently connected, and thus can transmit torque and can also rotate about the central axes of respective rings; in addition, the rotations about the two axes are very close, such that the eccentric distance is small, achieving flexible and reliable torque transmission, thus reducing floor scrubber costs.
