Solution Overview

Problem

Existing portable vacuum generator devices are inconvenient for transport and operation due to inadequate protection of the vacuum pump during transit and use, as they are not properly secured or insulated.

Innovation Solution

A portable vacuum generator device featuring a transport container with a capsule insert that securely encapsulates the vacuum pump, providing mechanical, electrical, and soundproof protection, with the pump remaining inside the container during operation and featuring a detachable cover for maintenance access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vacuum pump is transported in a transport container, then the pump is protected during transport, but the pump is inadequately protected from damage and electrical insulation is not maintained

Engineering Contradiction:
Improveprotection of vacuum pumpVSAvoidelectrical insulation and mechanical protection
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The vacuum pump is nested within a capsule insert that is received in the transport container. The capsule insert acts as an inner protective shell that encapsulates the pump, providing both mechanical protection and electrical insulation while maintaining a compact nested structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The capsule insert serves as an intermediary element between the vacuum pump and the transport container. It provides electrical insulation to prevent contact with the container walls and mechanical cushioning to protect the pump from impact during transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the vacuum pump is removed from the transport container for operation, then the pump is accessible for use, but the pump loses protection during operation and maintenance

Engineering Contradiction:
Improveaccessibility of vacuum pumpVSAvoidprotection of vacuum pump
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system transitions from a static protected state (pump in container) to a dynamic operational state (pump removed with capsule insert). The capsule insert remains attached to the pump during removal, dynamically maintaining protection while allowing operational accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The protective system is segmented into the capsule insert that stays with the pump and the transport container that remains stationary. This segmentation allows the pump to be removed for operation while retaining its protective encapsulation.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If the transport container is opened for maintenance access, then the pump is accessible for maintenance, but the pump is exposed to damage during access

Engineering Contradiction:
Improvemaintenance access to vacuum pumpVSAvoidexposure to damage
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The maintenance access system is segmented into three levels: the transport container opening, the capsule insert enclosure, and the pump itself. The capsule insert can be accessed through the container opening while remaining encapsulated, allowing maintenance without full exposure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The capsule insert is nested within the transport container, creating a hierarchical protection structure. Maintenance can be performed on the inner capsule without removing it from the outer container, maintaining protection while enabling access.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Reliability

If additional protective conductor cable is required for electrical safety, then electrical safety is improved, but the device complexity and installation requirements increase

Engineering Contradiction:
Improveelectrical safetyVSAvoidprotective conductor cable requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The capsule insert provides self-service electrical insulation by its very nature as an insulating enclosure. The insulating material of the capsule itself serves the protective function, eliminating the need for additional protective conductor cables or complex electrical safety systems.

Inventive Principle:
Principle #25Self-service

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

The solution ensures the vacuum pump is protected from damage and electrical insulation is maintained, eliminating the need for a protective conductor cable, while allowing easy maintenance and operation without exposing components during transit, enhancing the device's robustness and usability.

Implementation Method 1

The capsule insert expediently has a mechanical damping effect. For example, the capsule insert is elastic and / or acts as mechanical protection, in the manner of a shock absorber.

Methodology Applied
Scientific EffectMechanical damping: Damping

Implementation Method 2

It is also advantageous if the capsule insert is electrically insulating. In this way, for example, an ungrounded outer housing of the vacuum pump can be electrically insulated, so that no additional protective conductor cable is required.

Methodology Applied
Scientific EffectElectrical insulation: Electrical Resistance
