Cleaning Head Tilting Joint for Stable Two-Surface Floor Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices are not optimized for effective pressure distribution and user comfort, leading to increased physical effort and potential instability during use.
Innovation Solution
Incorporation of a tilting system between the cleaning head and articulation, allowing the articulation to move between two positions for improved force application and stability, reducing user effort and tilting risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the articulation is positioned away from the center of the cleaning head, then the device structure is simpler, but the pressure distribution becomes non-uniform and user effort increases
Solution Approach 1:
The articulation axis is made movable relative to the cleaning head surfaces through a tilting system, allowing it to dynamically reposition between a first position (when first surface contacts ground) and a second position (when second surface contacts ground). This dynamic positioning optimizes pressure distribution and reduces user effort while maintaining structural simplicity.
Solution Approach 2:
A tilting system acts as an intermediary mechanism between the cleaning head and the articulation, enabling the articulation axis to tilt and reposition. This intermediary system facilitates smooth transitions between cleaning surfaces while maintaining optimal force application points, resolving the contradiction between operational ease and structural complexity.
2Stability of the object's composition
If the articulation is fixed in one position, then the device structure is simpler, but stability decreases and unexpected tilting may occur
Solution Approach 1:
The articulation axis dynamically adjusts its position relative to the cleaning head through the tilting system, moving to the appropriate position depending on which surface contacts the ground. This dynamic adaptation prevents unexpected tilting and maintains stability without requiring a complex fixed positioning mechanism.
Solution Approach 2:
The position parameter of the articulation axis is changed based on the operational state (which surface is contacting the ground). The tilting system enables this parameter change, allowing the articulation to maintain optimal stability characteristics for each cleaning surface while avoiding the complexity of multiple fixed positioning systems.
3Ease of operation
If the articulation does not tilt between surfaces, then the device structure is simpler, but the transition between cleaning surfaces becomes difficult
Solution Approach 1:
The tilting system enables the articulation axis to dynamically tilt between a first position and a second position as the cleaning head transitions between cleaning surfaces. This dynamic tilting motion facilitates smooth and easy transitions between surfaces while maintaining a relatively simple device structure.
Solution Approach 2:
The tilting system introduces an additional degree of freedom (tilting motion) to the articulation mechanism. This dimensional change allows the articulation axis to reposition itself in space, enabling easy transitions between cleaning surfaces without requiring complex multi-axis positioning systems.
