Solution Overview
Problem
Existing self-moving cleaning devices experience poor stability when the water tank is removed, leading to shaking and impaired performance during operation.
Innovation Solution
A self-moving cleaning device with a roller assembly that retracts into a groove when the water tank is mounted and extends when removed, utilizing a torsion spring for automatic support, ensuring stability and contact with the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water tank is detachably mounted on the shell, then the ease of operation is improved, but the stability of the device deteriorates when the water tank is removed
Solution Approach 1:
The roller assembly is designed to dynamically change its state between retracted and extended positions based on the presence or absence of the water tank. When the water tank is mounted, the roller assembly retracts into the groove; when the water tank is removed, the roller assembly extends to provide support. This dynamic adaptation resolves the contradiction by allowing the device to maintain stability in both operational modes.
2Stability of the object's composition
If the roller assembly is fixed in position, then the stability is improved, but the adaptability to different operational modes deteriorates
Solution Approach 1:
The roller assembly transitions from a fixed position design to a dynamic position design, capable of moving between retracted and extended states. This is achieved through a groove structure that guides the roller assembly's movement and an elastic element that provides the restoring force, enabling the device to adapt to different operational modes while maintaining stability in each mode.
Solution Approach 2:
The roller assembly is designed to automatically extend and retract based on the presence or absence of the water tank without requiring manual intervention. The elastic element provides the self-service mechanism by automatically pushing the roller assembly into the extended position when the water tank is removed and facilitating retraction when the water tank is mounted, thereby adapting to operational modes autonomously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents unsteady operation by providing continuous support to the device, enhancing stability and smooth movement even after the water tank is removed.
Implementation Method 1
the elastic element drives the roller bracket and the roller into the extended state when the water tank is removed from the shell
Implementation Method 2
the elastic element is a torsion spring, a support part of the torsion spring is arranged on the mounting part, and a torsion coil part of the torsion spring is fitted over the pivot shaft

AI summary
Provided is a self-moving cleaning device, including a shell, a water tank, a groove, and a roller assembly. A mounting part is arranged at the bottom of the shell; the water tank is detachably mounted on the mounting part; the groove is provided in the mounting part and/or the groove is provided in the water tank at a position cooperating with the mounting part; and the roller assembly is mounted on the mounting part and can extend and retract. When the water tank is mounted on the shell, the roller assembly retracts into the groove and is in a retracted state, and when the water tank is removed from the shell, the roller assembly is in an extended state.
