Solution Overview
Problem
Existing cleaning robots lack adaptability as their cleaning modules cannot be lifted or lowered relative to the main body, limiting their ability to effectively clean various surfaces.
Innovation Solution
A cleaning assembly with a rotating shaft and gear part connected to a rotation transmission mechanism, allowing the cleaning module to be lifted or lowered axially, driven by a rotation drive motor, and featuring a lifting mechanism that adjusts the lifting angle of the cleaning module using a gear system, enabling self-adaptive floating and improved adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning module is made fixed relative to the main body, then the structure is simple and stable, but the adaptability to different surfaces is poor
Solution Approach 1:
The cleaning module is designed to be dynamically adjustable relative to the main body through a lifting mechanism. The module can be raised or lowered along the axial direction of the rotating shaft, allowing adaptation to different surface heights and cleaning requirements. This dynamic adjustment capability resolves the contradiction by enabling structural flexibility without compromising overall stability.
Solution Approach 2:
The cleaning assembly is segmented into independent components: the main body, the rotating shaft, the cleaning module, and the lifting mechanism. This segmentation allows the cleaning module to be independently adjusted and lifted, providing adaptability to different surfaces while keeping the overall structure organized and manageable.
2Adaptability or versatility
If a lifting mechanism is added to enable the cleaning module to move axially, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The lifting mechanism is integrated with the rotating shaft assembly, sharing common structural elements and mounting points. The cleaning module is connected to both the rotating shaft for rotation and the lifting mechanism for axial movement, merging multiple functions into a coordinated system that reduces overall complexity.
Solution Approach 2:
The rotating shaft serves multiple functions: it supports the cleaning module, enables rotational movement for cleaning, and works in conjunction with the lifting mechanism for axial positioning. This multi-functionality reduces the need for separate dedicated components, thereby controlling complexity while enhancing adaptability.
3Ease of manufacture
If the gear part is fixedly connected to the rotating shaft, then the manufacturing is simple, but the axial movement relative to the transmission gear is limited
Solution Approach 1:
The connection between the gear part and the rotating shaft is designed to allow controlled axial movement. While the gear part is fixedly connected for rotational stability, the assembly permits axial displacement relative to the transmission gear during lifting operations, achieving both manufacturing simplicity and movement capability.
Solution Approach 2:
The gear transmission system is segmented into the gear part on the rotating shaft and the transmission gear on the fixed structure. This segmentation allows the gear part to move axially relative to the transmission gear while maintaining rotational engagement, balancing ease of manufacture with adaptability.
