Solution Overview

Problem

Conventional three-chamber tube feeders face challenges in water distribution due to complex and costly flange connections, requiring long screws and DIN components, which restricts variability and increases assembly difficulties and material costs.

Innovation Solution

A transition block with a through bore and branching transverse bore is used for water distribution, eliminating the need for flanges and allowing for easier assembly and shorter screws, enabling larger bore diameters and reduced material costs, and can be integrated with a vent hole and pressure equalization connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If flange connections with T-pieces are used for water distribution, then reliable water distribution is achieved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvewater distribution reliabilityVSAvoidconnection structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the T-piece and flange connection components into a single integrated transition block. The transition block combines the water distribution function (T-piece) and the connection function (flange) into one component, eliminating the need for separate T-pieces and reducing the number of connection points. This integration simplifies the overall structure while maintaining reliable water distribution.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transition block serves multiple functions simultaneously: it acts as a T-piece for water distribution, provides flange connections for piping, and integrates the connection structure. This multi-functionality reduces the number of separate components needed, simplifying the device while maintaining reliability.

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

2Reliability

If flange connections with T-pieces are used, then water distribution is achieved, but assembly difficulty increases due to long screws and lack of space

Engineering Contradiction:
Improvewater distributionVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By combining the T-piece and flange into a single transition block, the patent eliminates the need for long screws that would be required to fasten separate T-pieces to flanges. The integrated design allows for shorter, easier-to-install fasteners and reduces the assembly space requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transition block is designed as a modular component that can be installed as a single unit, simplifying the assembly process. The segmented design allows for easier installation compared to assembling multiple separate components (T-piece, flanges, screws) in sequence.

Inventive Principle:
Principle #1Segmentation

3Reliability

If T-pieces with flange connections are used, then water distribution is achieved, but material and production costs increase

Engineering Contradiction:
Improvewater distributionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent reduces material costs by merging multiple components (T-piece, flanges, screws) into a single transition block. This integration eliminates the need for separate components, reducing the total material quantity required and lowering manufacturing costs while maintaining water distribution functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transition block performs multiple functions (water distribution, connection, support) within a single component, reducing the total number of parts that need to be manufactured and assembled. This multi-functionality directly reduces material and production costs compared to assembling separate T-pieces and flanges.

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

4Reliability

If flange connections are used, then water distribution is achieved, but bore diameter is restricted due to flange requirements

Engineering Contradiction:
Improvewater distributionVSAvoidbore diameter variability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

By eliminating the flange connection structure and integrating it into the transition block body, the patent removes the constraint on bore diameter. The streamlined design allows for larger bore diameters that were previously limited by flange dimensions, enabling better water flow characteristics.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transition block design allows for optimization in the bore diameter dimension without being constrained by flange dimensions. This dimensional freedom enables larger bore diameters that improve flow efficiency while maintaining the same connection functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The feeder (1) has a rectangular or box-shaped transition block (21) with a through-hole (26) and a branching cross-hole (27), and arranged on ends of a pipe chamber (2) for distribution of water to a high pressure line or a low pressure line. The transition block is provided with a vent hole to the pipe chamber, and comprises a connection to a pressure balancing slide and a hydraulic cylinder connection for actuation of a locking unit i.e. valve (32).
