Cleaning Tool Cover with Crossed Thread Planes for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools with mesh cover members vibrate excessively during ultrasonic cleaning, causing the to-be-cleaned objects to be dislodged and leading to insufficient cleaning due to restricted movement of threads and obstruction of cleaning solution and ultrasonic waves.
Innovation Solution
A cleaning tool design featuring a cover member with tensioned thread-like members forming two plane sections, where the second plane section crosses and stabilizes the first plane section to prevent vibration while allowing free movement of cleaning solutions, ensuring thorough cleaning without dislodging the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the rigidity of the thread is enhanced by increasing the tension or making the mesh finer and tighter, then the vibration of the net is reduced and objects are less likely to be dislodged, but the warp threads and woof threads become obstructions that prevent the cleaning solution or ultrasonic wave from reaching the device
Solution Approach 1:
The net is divided into two separate plane sections (first plane section with threads in first direction, second plane section with threads in second direction) instead of a single braided mesh. This segmentation allows each plane section to maintain stability in its respective direction without creating the obstructive braided structure, enabling cleaning solution and ultrasonic waves to pass through more effectively.
Solution Approach 2:
The invention transitions from a two-dimensional braided mesh to a three-dimensional structure with two parallel plane sections. The second plane section is positioned above the first plane section, creating a spaced configuration that allows cleaning solution and ultrasonic waves to reach the device through the gap between the sections, while both sections collectively provide enhanced stability.
2Reliability
If the net is made with lower tension and coarser mesh to allow free movement of cleaning solution, then cleaning effectiveness is improved, but the net vibrates excessively during cleaning causing objects to be dislodged
Solution Approach 1:
The net is segmented into two separate plane sections with threads running in different directions. Each plane section can be made with lower tension and coarser mesh for better cleaning solution penetration, while the combination of both sections provides enhanced overall stability to prevent excessive vibration and object dislodgement.
Solution Approach 2:
Two plane sections with different thread orientations are merged into a single cover member structure. The first plane section with threads in the first direction and the second plane section with threads in the second direction work together to provide both stability and cleaning effectiveness, combining the benefits of both configurations.
3Adaptability or versatility
If the volume of the space is increased to accommodate larger objects, then versatility is improved, but the objects may come out from the accommodating space during cleaning
Solution Approach 1:
The cover member with its two-plane-section net structure provides a dynamic balance between space volume and containment stability. The net configuration allows the space volume to be adjusted for different object sizes while maintaining sufficient stability to prevent objects from being dislodged during ultrasonic cleaning vibrations.

AI summary
A cleaning tool has a tray 10 and a cover member 20. The tray has a space for individually accommodating a to-be-cleaned object D. The cover member has a frame 21, and thread-like members 22 and 23. The thread-like members 22 are tensioned to the frame along a first direction so as to form a first plane section that defines the top portion of the space. The thread-like members 23 are tensioned to the frame along a second direction so as to form a second plane section above the first plane section. When the thread-like members 22 are about to vibrate during the cleaning, the thread-like members 23 restrict this vibration. Further, each thread-like member can relatively freely move in each plane section.
