Centrifugal Pump Rotary Guide for Reorientable Operating Part

Solution Overview

Problem

Existing pump designs require complex and risky electrical disconnections for reorienting the operating part, which can lead to damage and safety issues, especially when handled by untrained personnel.

Innovation Solution

The operating part is connected to the pump housing via a non-detachable rotary guide, allowing for rotation into different fixing positions without disconnection of the electrical connection, thus simplifying and safer reorientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the operating part is detached and reconnected via plug connection to change position, then the pump can be reoriented, but the electrical connection becomes complex and risky

Engineering Contradiction:

Improvereorientation capabilityVSAvoidelectrical connection complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the mechanical connection function and electrical connection function into a single integrated rotary guide mechanism. The rotary guide simultaneously provides rotational movement capability and maintains continuous electrical connection through integrated cable routing, eliminating the need for separate plug connections and strain relief means.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rotary guide acts as an intermediary mechanism that enables position change while maintaining electrical connection. It serves as a mediator between the operating part and pump housing, allowing rotation while continuously guiding the cable to prevent disconnection or damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the operating part is detached and reconnected to change position, then the pump can be reoriented, but safety risks increase for untrained personnel

Engineering Contradiction:

Improvereorientation capabilityVSAvoidconnection safety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines the mechanical connection function and electrical connection function into a single integrated rotary guide mechanism. The rotary guide simultaneously provides rotational movement capability and maintains continuous electrical connection through integrated cable routing, eliminating the need for separate plug connections and strain relief means.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rotary guide acts as an intermediary mechanism that enables position change while maintaining electrical connection. It serves as a mediator between the operating part and pump housing, allowing rotation while continuously guiding the cable to prevent disconnection or damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the operating part is completely separated from the pump housing, then position can be changed, but the process becomes slower and more complex

Engineering Contradiction:

Improveposition change capabilityVSAvoidrelocation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines the mechanical connection function and electrical connection function into a single integrated rotary guide mechanism. The rotary guide simultaneously provides rotational movement capability and maintains continuous electrical connection through integrated cable routing, eliminating the need for separate plug connections and strain relief means.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rotary guide is pre-configured with integrated cable routing and guiding elements that automatically maintain electrical connection during rotation. This preliminary design eliminates the need for manual disconnection and reconnection steps, allowing operators to simply rotate the operating part to the desired position.

Inventive Principle:

Principle #10Preliminary action
