Multi-Suction Vacuum Device with Segmented Plate to Prevent Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum suction devices experience reduced suction power over time due to external forces applied to the center portion, leading to unintended detachment and damage, especially when repeatedly attached and detached, requiring urethane gel application for sufficient suction.
Innovation Solution
A vacuum suction device with a disk-shaped suction plate, a cylindrical rotor, and a base member, featuring a specific structure that includes a disk-shaped insert, rotor, and a cap, allowing for easy attachment and detachment while maintaining strong suction through a combination of injection grooves, anti-slip ribs, and guide protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vacuum suction device with a cover and height adjustment member is used, then the device can be attached to smooth surfaces, but the suction power decreases over time when external force is applied to the center portion
Solution Approach 1:
The suction plate is divided into a rigid peripheral portion and a flexible central portion. The peripheral portion maintains the vacuum seal against the attachment surface, while the central portion flexes independently to maintain contact under external loads, preventing loss of suction power.
Solution Approach 2:
Different regions of the suction plate have different mechanical properties: the peripheral region is rigid to maintain sealing, while the central region is flexible to adapt to external forces. This local differentiation allows the plate to maintain both seal integrity and contact pressure under various loading conditions.
2Force
If urethane gel is applied to the suction surface to provide sufficient suction power, then strong suction is achieved, but the device complexity increases
Solution Approach 1:
The flexible central portion of the suction plate automatically adjusts its shape and contact pressure in response to external forces and surface irregularities, maintaining effective suction without requiring additional materials like urethane gel or complex adjustment mechanisms.
3Ease of operation
If the vacuum suction device is repeatedly attached and detached through rotation operation, then ease of operation is improved, but parts may be damaged thereby shortening service life
Solution Approach 1:
The rotor and cap assembly is extracted as a separate detachable unit from the suction plate. This allows the suction plate to remain stationary on the attachment surface while the rotor-cap unit is easily removed or rotated for detachment, reducing mechanical stress and wear on the suction plate during repeated operations.
