Suction Cup Pressure Relief Assembly for Easy Vacuum Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction cups require inconvenient manual operation to break vacuum, which hampers efficiency in applications like ski edge sharpening devices.
Innovation Solution
A pressure relief device for suction cups, comprising a rod body with an air pipeline and a pressure relief assembly that includes a blocking end and a pressure relief member, allowing the blocking end to be controlled to either close or open the air hole, facilitating easy transition between vacuum and non-vacuum states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to break vacuum of suction cup, then the suction cup can be released from vacuum, but the operation is inconvenient and reduces efficiency
Solution Approach 1:
The suction cup system performs the vacuum breaking operation automatically through the elastic member that pushes the blocking end away from the air hole when the suction cup is detached from the workpiece, eliminating the need for manual intervention and enabling the system to serve itself
Solution Approach 2:
The manual mechanical operation of breaking vacuum is replaced by an automatic mechanical mechanism consisting of the elastic member and blocking end that respond automatically to the suction cup's attachment and detachment states
2Ease of operation
If automatic pressure relief mechanism is added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The pressure relief function is merged with the existing suction cup structure by integrating the blocking end and elastic member into the rod body, combining multiple functions (sealing, pressure relief, and actuation) into a unified structure rather than adding separate components
Solution Approach 2:
The rod body serves multiple functions: it provides structural support, contains the air pipeline, houses the blocking end, and incorporates the elastic member for automatic actuation, making a single component perform multiple roles to reduce overall system complexity
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 efficient operation of multiple suction cups by allowing easy release from vacuum, improving operational efficiency in applications such as ski edge sharpening devices.
Implementation Method 1
Suction cups are a kind of items attached to an object by virtue of a difference in internal and external atmospheric pressures
Implementation Method 2
the first blocking end can block the first air hole under the drive of the first pressure relief member to close the air pipeline
Implementation Method 3
the first blocking end can be separated from the first air hole under the drive of the first pressure relief member to make the air pipeline in communication with the outside
