Sweeper head and hand-held sweeper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held sweepers have a single operating mode and a complex structure, making them difficult to operate in various working conditions, and their shields do not adaptively protect the user from different operating modes and conditions.
Innovation Solution
A sweeper head with a cleaning device, transmission shaft, shield, and connecting rod, where the shield has a specific design with a front and rear surrounding portion ratio, reinforcing ribs, and adjustable installation states to accommodate different operating modes, ensuring effective protection and efficient debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single operating mode is used in existing hand-held sweepers, then the structure can be simplified, but the adaptability to different working conditions deteriorates
Solution Approach 1:
The shield is designed with adjustable positioning capability, allowing it to switch between different installation states (first installation state and second installation state) to adapt to different operating modes. The shield can be positioned at different locations relative to the cleaning element, enabling the sweeper to handle both light debris and heavy debris effectively.
Solution Approach 2:
The shield serves multiple functions: it provides protection against debris, allows adjustment between different operating modes, and can be positioned to accommodate various cleaning scenarios. This multi-functionality resolves the contradiction by enabling a single device to handle diverse working conditions without requiring multiple specialized components.
2Adaptability or versatility
If a complex structure with multiple operating modes is used, then the adaptability to different working conditions is improved, but the ease of operation deteriorates
Solution Approach 1:
The shield's adjustable design allows users to switch between different installation states depending on the operating mode. In the first installation state, the shield provides comprehensive protection for heavy debris scenarios. In the second installation state, it optimizes performance for light debris. This dynamic adjustment capability enables the device to adapt to different conditions while maintaining operational simplicity.
3Device complexity
If the shield has a single protection mode, then the structure can be simplified, but the protection effectiveness against different debris types deteriorates
Solution Approach 1:
The shield can be installed in different states to provide appropriate protection for different debris types. The first installation state offers enhanced protection for heavy debris scenarios, while the second installation state is optimized for light debris. This dynamic reconfiguration capability ensures reliable protection effectiveness across various operating conditions without requiring a overly complex shield structure.

AI summary
A sweeper head includes a cleaning device, a transmission shaft, and a shield. The cleaning device includes a rolling member rotatable about a first axis and a cleaning element. The transmission shaft is rotatable about a second axis. The shield includes a surrounding portion for surrounding at least a part of the cleaning element. The surrounding portion includes a front surrounding portion and a rear surrounding portion located on two sides of a first plane and the first plane passes through the second axis and is parallel to the first axis. The ratio of a maximum measurement of the front surrounding portion in a direction parallel to the first axis to a maximum measurement of the rear surrounding portion in the direction is greater than or equal to 2 and is less than or equal to 3.
