Sweeper Brush with Automatic Drive Control via Rod Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brooms lack ease of operation and versatility due to complex mechanisms and the need for manual switching of the brush roller drive, making them difficult to use for various cleaning tasks and storage.
Innovation Solution
A broom design featuring a fixing device coupled with a blocking device that automatically stops the brush roller drive when the rod device is locked into a specific position, allowing for easy operation and storage without the need for manual switches, and enabling flexible pivoting for enhanced cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual switch is provided to control the brush roller drive, then the drive can be stopped when the rod assembly is in storage position, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system automatically controls the drive motor based on the rod assembly position. The fixing device detects whether the rod assembly is in the fixed storage position and automatically stops or activates the drive motor without requiring manual intervention. This eliminates the need for separate switches and makes the system self-regulating.
Solution Approach 2:
The fixing device provides feedback about the rod assembly position to the drive control system. When the rod assembly is detected to be in the fixed position, the system receives feedback to stop the drive motor; when moved away, feedback triggers motor activation. This closed-loop control eliminates manual switching complexity.
2Adaptability or versatility
If the rod assembly is made pivotable for height adjustment, then adaptability improves, but device complexity increases
Solution Approach 1:
The rod assembly is designed with a pivot connection to the sweeping head, allowing it to be dynamically adjusted to different heights and angles. This pivotable connection enables the rod assembly to adapt to various user heights and cleaning situations while maintaining structural simplicity through a single rotational degree of freedom.
3Adaptability or versatility
If the rod assembly is made rotatable for lateral positioning, then versatility improves, but device complexity increases
Solution Approach 1:
The second part of the rod assembly is designed to rotate relative to the first part about a rod rotation axis. This rotational capability allows the sweeping brush to be positioned laterally offset from the operator during cleaning operations, enabling access to difficult-to-reach areas while maintaining a simple two-part rotational joint structure.
