Solution Overview
Problem
Existing thumb pump systems for suction cups are inefficient and hazardous due to independent operation of multiple pumps, requiring manual and time-consuming pressure application and release, especially in high locations, which can be dangerous and inconvenient.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple independent thumb pumps are used for multiple suction cups, then each suction cup can be independently operated, but the operation becomes time-consuming and hazardous especially in high locations
Solution Approach 1:
Multiple suction cups are connected to a common vacuum source through a vacuum distribution manifold, allowing a single thumb pump to control all suction cups simultaneously. This merging of previously independent pump-suction cup pairs into a unified system eliminates the need to operate multiple pumps individually, significantly reducing operation time and improving ease of use.
Solution Approach 2:
The vacuum distribution manifold serves multiple functions: it distributes vacuum from a single pump to multiple suction cups, provides a centralized pressure release mechanism, and offers a convenient location for the pressure release tab that is accessible regardless of the orientation of individual suction cups. This multi-functional component resolves the time-loss contradiction by consolidating control operations.
2Ease of operation
If multiple independent thumb pumps are used for multiple suction cups, then each suction cup can be independently operated, but the operation becomes hazardous especially in high locations
Solution Approach 1:
By merging multiple suction cup controls into a single centralized system with one thumb pump and one pressure release tab, the invention eliminates the need for operators to repeatedly position themselves at different locations around the workpiece. This is particularly hazardous when working at heights, as it minimizes the operator's exposure to dangerous positioning and movement.
Solution Approach 2:
The vacuum distribution manifold acts as an intermediary between the single thumb pump and multiple suction cups, and between the single pressure release tab and all suction cups. This intermediary component enables centralized control and pressure release, eliminating the need for direct manual intervention at each suction cup location, thereby reducing operational hazards.
3Adaptability or versatility
If pressure release tabs are positioned on each suction cup, then each can be independently released, but the tabs may be rotated and blocked by the frame making them inaccessible
Solution Approach 1:
The pressure release function is extracted from the individual suction cups and consolidated into a separate, centralized pressure release tab on the vacuum distribution manifold. This extracted function is positioned in a location that is always accessible to the operator, independent of the orientation or position of individual suction cups, eliminating the accessibility problems caused by rotation and frame obstruction.
Solution Approach 2:
The vacuum distribution manifold serves as an intermediary that decouples the pressure release function from the individual suction cup orientations. By providing a centralized pressure release tab on the manifold, the system allows all suction cups to be released simultaneously through a single accessible point, regardless of how the suction cups or frame are positioned or rotated.
