Vacuum-Suction Holder for Stable Grip and Easy Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders that use suction cups to secure foodstuff receptacles on countertops can be difficult to remove due to strong attachment, making it challenging to manipulate items without applying force or risking tilting.
Innovation Solution
A holder with a suction port on the bottom face that creates a partial vacuum, allowing for easy removal by ending the vacuum action and using a large suction pad for secure adherence, featuring a vacuum pump driven by an electric motor and gaskets for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction cups are used to secure the holder to the countertop, then the holder is prevented from moving or tilting during item manipulation, but the holder becomes difficult to remove requiring application of force
Solution Approach 1:
The suction system transitions from a static strong attachment (suction cups) to a dynamic controllable attachment (vacuum pump with on/off control). The vacuum pump can be activated to create strong suction for stability during use, and deactivated to release the holder for easy removal, making the attachment strength adjustable rather than fixed.
Solution Approach 2:
The invention extracts the suction function from permanent suction cups and relocates it to a controllable vacuum pump system. This separates the suction generation function from the attachment mechanism, allowing the suction to be activated only when needed for stability and deactivated when removal is required.
2Strength
If a large suction pad is used to secure the holder, then stronger adherence force and more rigid connection are achieved, but the suction area increases making the holder larger
Solution Approach 1:
The invention uses a vacuum pump to create a partial vacuum within the suction pad, utilizing pneumatic pressure differential to generate strong adherence force. The vacuum pump creates negative pressure that pulls the suction pad against the countertop surface, achieving strong attachment without requiring a large physical pad area.
Solution Approach 2:
The invention changes the pressure parameter within the suction pad by creating a partial vacuum environment. By reducing the pressure inside the suction pad relative to atmospheric pressure, strong adherence force is generated without increasing the physical dimensions of the holder or suction pad.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure attachment and easy removal of the holder from the countertop without applying force, providing a stronger and more rigid connection to prevent inadvertent movement or tilting, facilitating one-handed use and efficient item handling.
