Vacuum suction device
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 unintentional detachment and potential damage, and require urethane gel for sufficient suction, which shortens the product's service life.
Innovation Solution
A vacuum suction device with a disk-shaped suction plate, a cylindrical rotor, and a base member, featuring a specific structure that allows for easy attachment and detachment while maintaining strong suction, using a soft synthetic resin material and a disk-shaped insert with coupling protrusions, and a cap that rotates to lift the rotor and insert, ensuring firm fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a cover is mounted on the suction plate to provide stronger suction, then suction power is improved, but the structure becomes more complex and parts may be damaged during rotation operation
Solution Approach 1:
The device is divided into separate functional components: a suction plate for generating suction force, a rotor for rotation operation, and a base member for support. This segmentation allows each part to perform its specific function independently, reducing overall structural complexity while maintaining strong suction capability.
Solution Approach 2:
The cover structure is removed entirely from the design. Instead of mounting a cover on the suction plate, the patent uses a simplified configuration where the rotor rotates directly on the suction plate with guide protrusions that engage with guide grooves in the base member, eliminating the complex cover assembly.
2Force
If urethane gel is applied to the suction surface to provide sufficient suction power, then suction performance is improved, but the service life of the product is shortened
Solution Approach 1:
The patent avoids using urethane gel entirely, which is a consumable material with limited service life. Instead, the design relies on the mechanical structure of the rotor with guide protrusions and the base member with guide grooves to maintain suction, eliminating the need for replacement gel and extending product service life.
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 and service life is shortened
Solution Approach 1:
The rotor is designed to rotate dynamically on the suction plate, with guide protrusions that engage with guide grooves in the base member. This dynamic rotation mechanism allows easy attachment and detachment while the guided movement prevents excessive stress on parts, maintaining reliability during repeated operations.
