Solution Overview

Problem

Existing vacuum devices in the beverage industry, particularly those with single vacuum pumps, face limitations in adjusting vacuum or suction power, leading to increased costs, inefficient operation, and limited flexibility due to the need for multiple pumps and spare parts for different power requirements.

Innovation Solution

A vacuum device comprising multiple identical vacuum pumps operating in parallel, with the total suction power controlled by adjusting the speed and number of active pumps, allowing for efficient power management and reduced storage costs through frequency control and redundant systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single vacuum pump is used with fixed capacity, then the system is simple and cost-effective, but the vacuum performance cannot be adjusted over a wide range and efficiency deteriorates under varying load conditions

Engineering Contradiction:
Improvevacuum performance adjustment rangeVSAvoidnumber of vacuum pumps
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vacuum system is segmented into multiple identical vacuum pumps that can operate independently or in combination. Each pump is a separate module with the same design and performance characteristics, allowing the system to be divided into functional units that can be activated based on the required vacuum capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the number of active vacuum pumps based on the required suction capacity. The control system activates or deactivates individual pumps to match the current operational demands, enabling the vacuum performance to be adjusted over a wide range while maintaining optimal efficiency.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple different vacuum pumps are provided for varying vacuum performance, then the vacuum device can adapt to different requirements, but storage costs and spare parts inventory increase

Engineering Contradiction:
Improvevacuum performance variation capabilityVSAvoidnumber of different vacuum pumps and spare parts
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system uses multiple identical vacuum pumps with uniform design, performance parameters, and interchangeability. All pumps are homogeneous in their construction and operational characteristics, which simplifies storage, maintenance, and spare parts inventory management compared to using different types of pumps for different performance levels.

Inventive Principle:
Principle #33Homogeneity

Solution Approach 2:

Each vacuum pump is designed as a universal unit that can perform the same function in different configurations. The identical design allows any pump to replace any other pump in the system, providing versatility in system configuration without requiring multiple specialized pump types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the vacuum pump speed is adjusted to accommodate changes in suction capacity, then some flexibility is achieved, but efficiency becomes poor under certain operating conditions

Engineering Contradiction:
Improvesuction capacity adjustmentVSAvoidvacuum pump efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Instead of running a single pump at variable speeds, the system activates only the necessary number of pumps at their optimal operating speed. This partial action approach ensures that each active pump operates efficiently without being overloaded or underloaded, avoiding the energy losses associated with speed adjustment.

Inventive Principle:
Principle #16Partial or excessive action
