Rotatable Brush Head Locking Mechanism for Adjustable Cleaning Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning tools lack the ability to adjust the angle of the brush head, limiting their versatility and convenience in cleaning tasks.
Innovation Solution
A rotatable adjusting cleaner is designed with a rotational adjusting mechanism between the brush head mounting handle and the rotational handle, featuring an adjusting cavity, teeth rows, and a restoring elastic member, allowing for adjustable angle settings and secure locking, along with a detachable brush head and extension rod for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed brush head structure is used, then the device structure is simple, but the adaptability to different cleaning needs is poor
Solution Approach 1:
The brush head structure transitions from a fixed state to a dynamically adjustable state through the rotational adjusting mechanism. The adjusting tooth can move between engaged and disengaged states with the cooperating tooth, enabling the brush head to rotate and lock at different angles according to cleaning needs, thus achieving adaptability while maintaining structural simplicity.
Solution Approach 2:
The adjusting mechanism is segmented into discrete components: adjusting tooth, cooperating tooth, restoring elastic member, and adjusting piece. This segmentation allows each component to perform its specific function independently while working together to achieve the overall angle adjustment capability, resolving the contradiction between functionality and complexity.
2Ease of operation
If the adjusting tooth is always clamped by the cooperating tooth, then the connection is stable, but the angle adjustment is impossible
Solution Approach 1:
The adjusting tooth periodically engages and disengages with the cooperating tooth during the adjustment process. When adjustment is needed, the adjusting piece pushes the adjusting tooth to disengage from the cooperating tooth, allowing rotation. After adjustment, the restoring elastic member pushes the adjusting tooth back to engage with the cooperating tooth, providing stable locking. This periodic engagement-disengagement cycle enables both adjustability and stability.
Solution Approach 2:
The restoring elastic member automatically pushes the adjusting tooth back into engagement with the cooperating tooth after adjustment, providing self-locking functionality. The system uses its own elastic member to restore the connection stability without requiring additional locking mechanisms or manual intervention, thus maintaining reliability while enabling easy adjustment.
