Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners with integrated rotation and translation motion structures are complex and often fail to accurately follow user movement, leading to inaccurate cleaning path alignment and potential collisions with obstacles.
Innovation Solution
A vacuum cleaner system with a moving device, suction device, detection device, and controller that adjusts movement based on distance and obstacle detection, using ultrasonic waves and current sensors to determine necessary actions, allowing the cleaner body to follow user movement and avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a structure integrating rotation and translation motions is provided, then the vacuum cleaner can move and clean simultaneously, but the structure becomes complicated
Solution Approach 1:
The patent divides the motion control into separate functions: the moving device handles translation movement independently, while the suction device handles cleaning operations. The detection device separately monitors handle position and translates it to cleaner body movement, avoiding the need for a complex integrated rotation-translation structure.
2Ease of operation
If movement is detected by mechanical operation, then the driving unit is moved, but actual user movement is not accurately detected
Solution Approach 1:
The patent replaces mechanical operation detection with an ultrasonic detection system. The detection device uses ultrasonic waves to measure the distance between the handle and cleaner body, converting mechanical movement into electronic signals for precise tracking of user movement without relying on mechanical sensors.
3Ease of operation
If the cleaner body follows user movement directly, then user convenience is improved, but collision with obstacles cannot be avoided
Solution Approach 1:
The patent implements a feedback control system where the detection device continuously monitors both handle position and obstacle locations. The controller adjusts the cleaner body's movement in real-time based on this feedback, allowing the cleaner to follow user movement while automatically detecting and avoiding obstacles by modifying its path when obstacles are detected.

AI summary
Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body including a moving device for moving, a suction device connected to the cleaner body to suction dusts and air and guide the suctioned dusts and air to the cleaner body, the suction device including a handle, a detection device for detecting a distance between the handle and the cleaner body, and a controller determining whether movement of cleaner body is necessary on the basis of the distance between the cleaner body and the handle, the controller controlling the moving device when the movement of the cleaner body is necessary. The controller controls the moving device to allow the cleaner body to avoid an obstacle when it is determined that an operation for avoiding the obstacle is necessary while the moving device operates.
