Suction Pad Lid Mechanism for Rapid Pressure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction pads face challenges in quickly releasing suction of lighter objects, as they tend to remain attached for longer periods compared to heavier objects due to the time required for negative pressure to return to atmospheric pressure.
Innovation Solution
A suction pad design featuring a hollow pad main body with an intake hole, negative pressure generating holes, a negative pressure breaking hole, and a lid section, where the lid section is moved to open the negative pressure breaking hole, allowing air inside the pad to escape and breaking the negative pressure more quickly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the negative pressure is broken by simply stopping gas jetting, then the device complexity is reduced, but the suction release time increases especially for lighter objects
Solution Approach 1:
The negative pressure breaking hole is prepared in advance within the pad main body, and the lid section is positioned ready to block or unblock it. When suction release is needed, the lid section is moved to unblock the hole, allowing rapid pressure equalization. This preliminary preparation enables fast suction release without requiring complex external systems.
Solution Approach 2:
The lid section acts as an intermediary element that controls the negative pressure breaking hole. By moving the lid section between blocked and unblocked positions, the system can rapidly transition between suction holding and suction release states, solving the contradiction between simple device structure and fast suction release.
2Speed
If the lid section is moved to open the negative pressure breaking hole, then the suction release speed is improved, but the device complexity increases
Solution Approach 1:
The lid section is designed to be movable under its own weight or with minimal actuation force. The gravity or spring mechanism allows the lid section to automatically move between blocked and unblocked positions, enabling fast suction release without requiring complex external actuation systems.
Solution Approach 2:
The lid section transitions from a static blocked state to a dynamic unblocked state when suction release is needed. This dynamic configuration allows the system to maintain simple structure during normal operation while enabling rapid suction release when required.
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
This design enables faster release of suction for both heavy and light objects by actively opening the negative pressure breaking hole, reducing the time required for suction release compared to simply stopping the gas jetting.
Implementation Method 1
a negative pressure generating hole provided in a bottom wall section on a side facing a suction object in the pad main body, the negative pressure generating hole being for generating a negative pressure between the bottom wall section and the suction object by jetting the gas flowing in from the intake hole
Implementation Method 2
when the negative pressure breaking hole opens, air on the inside of the pad main body flows to outside from the negative pressure breaking hole, whereby the negative pressure that had been generated between the bottom wall section of the pad main body and the suction object is broken
