A hand-guided floor treatment device with a rotatable tool that exerts permanent linear propulsion, allowing the bottom part to move automatically in a straight line, and an articulated arrangement that enables torque transmission in various angular positions, simplifying control and reducing operator effort, suitable for both dry and wet operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pushing or pulling is used to maneuver the floor treatment device, then the device can be moved to different locations, but the operator effort required is significant
Solution Approach 1:
The rotatable tool serves dual functions: it performs floor treatment while simultaneously generating linear propulsion to move the bottom part forward automatically, eliminating the need for operator pushing or pulling
Solution Approach 2:
The manual mechanical pushing/pulling system is replaced with an automatic propulsion system where the rotatable tool's rotation directly generates linear movement through mechanical conversion
2Adaptability or versatility
If the guide part is made highly pivotable in all directions, then the device can access difficult areas, but the torque transmission to the bottom part becomes limited
Solution Approach 1:
The articulated arrangement provides dynamic torque transmission that adapts to different angular positions, maintaining effective force transmission while allowing extensive guide part mobility for accessing difficult areas
3Productivity
If the rotatable tool is designed for linear propulsion, then automatic forward movement is achieved, but the tool can only rotate in the direction of propulsion
Solution Approach 1:
The rotatable tool is designed with multi-functionality, serving both as the floor treatment tool and as the propulsion mechanism, where its rotation in the propulsion direction simultaneously drives both functions
