Vacuum Pump Connector Attachment Member Phase Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum pumps face difficulties in changing the phase of attachment of the control power source with respect to the pump main body, limiting flexibility in equipment layout and requiring additional connection ports, which complicates the attachment process and increases costs.
Innovation Solution
A vacuum pump design featuring a connector device with detachable connector members and a shutter flange-like connector attachment member that allows for flexible attachment phases, enabling the power source unit to be positioned coaxially with the pump shaft center at various angular phases, thus simplifying the attachment process and eliminating the need for additional adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection port is newly provided at a different position to change the phase of attachment of the control power source, then the phase of attachment can be changed, but the device complexity increases and additional connection ports are required
Solution Approach 1:
The connector attachment member is designed with multiple connection ports positioned at different phases (e.g., 0° and 180°) relative to the pump shaft center. This allows the same member to accommodate different attachment phases for the control power source without requiring multiple different members or increasing overall system complexity. The single member serves multiple attachment configurations.
2Ease of operation
If the connector attachment member is attached at a fixed position, then the attachment process is simple, but the flexibility in equipment layout is reduced
Solution Approach 1:
The connector attachment member is designed with rotational flexibility, allowing it to be attached to the pump main body at multiple predetermined phases (e.g., 0° and 180°) relative to the pump shaft center. This dynamic attachment capability enables the control power source to be positioned at different angular locations while maintaining simple attachment procedures through standardized connector interfaces.
3Adaptability or versatility
If additional adapters are used to change attachment phase, then phase flexibility is achieved, but the cost and height of the pump system increase
Solution Approach 1:
The connector attachment member integrates the phase-change functionality directly into the pump main body assembly, eliminating the need for separate adapter components. By combining the connector member with the pump main body structure, the design achieves attachment phase flexibility without adding external adapters that would increase system height and cost.

AI summary
A vacuum pump includes: a pump main body; a control unit which drives and controls the pump main body; a connector device including a first connector member on the pump main body side and a second connector member on the control unit side, at least one of power and a control signal being input and output between the pump main body and the control unit; and a connector attachment member attached to the pump main body coaxially with the pump shaft center between the pump main body and the control unit, the first connector member being attached to the connector attachment member. The connector attachment member is attached to the pump main body at one of a first phase of attachment and a second phase of attachment depending on a phase of attachment of the pump main body and the control unit.
