Solution Overview

Problem

Existing vacuum lifting devices lack an ergonomic and compact control system, leading to inefficient operation and handling of loads, particularly in manual applications where response time and weight distribution are critical.

Innovation Solution

A modular, socket-shaped distributor block with integrated valve devices allows for fluid connections and quick response times, enabling precise control of vacuum lifting devices with a compact and ergonomic design, protecting components from external influences and facilitating even weight distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a compact distributor block design is used, then the response time of valve devices is optimized, but the device complexity increases

Engineering Contradiction:
Improveresponse timeVSAvoiddevice complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines multiple flow channels (first, second, and third flow channels) and valve devices into a single integrated distributor block. This merging of components into one compact unit reduces the overall response time by eliminating multiple connection points and potential leak paths, while the modular internal structure manages the complexity through systematic integration rather than scattered components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distributor block employs a nested structure where multiple flow channels are arranged concentrically or in nested patterns within the single block body. The first flow channel connects to the second, which connects to the third, creating a nested flow path architecture that minimizes external connections while maintaining functional separation, thus reducing response time without proportionally increasing complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a modular distributor block is used, then the vacuum lifting device becomes more versatile, but the manufacturing precision requirements increase

Engineering Contradiction:
ImproveversatilityVSAvoidmanufacturing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The distributor block is designed as a universal component that can be applied to various vacuum lifting device configurations. By integrating multiple flow channels and valve connections into one standardized block, the same component can serve different application requirements, enhancing versatility. The standardized接口 design allows the block to adapt to different suction hose configurations without requiring custom-manufactured parts, thereby managing manufacturing precision requirements.

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

3Reliability

If the distributor block is integrated within the suction hose, then the device becomes more compact and reliable, but the ease of repair decreases

Engineering Contradiction:
ImprovereliabilityVSAvoidease of repair
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The distributor block is integrated within the suction hose assembly, merging the control functions into the existing structural envelope. This integration eliminates external wiring and connection points that could fail, improving reliability. The block utilizes the suction hose's existing protective environment, so the merging leverages the hose's inherent protection rather than requiring separate protective structures.

Inventive Principle:
Principle #5Merging (Combining)
