Solution Overview

Problem

Existing plumbing systems require separate distribution devices for hot and cold fluids, which can be complex and inefficient, especially when integrating both types in a single installation.

Innovation Solution

A one-piece distribution device with a hot side and a cold side, separated by a wall section, allowing for simultaneous distribution of hot and cold fluids, optionally with thermal insulation and mounting means, and connected via clamping rings made of cross-linked polyolefin with memory properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate distribution devices are used for hot and cold fluids, then each device can be optimized for its specific function, but the overall system complexity increases and installation becomes less efficient

Engineering Contradiction:
Improvedistribution capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines separate hot and cold distribution devices into a single integrated distribution device. The device includes a hot fluid distribution section with hot outlets and a cold fluid distribution section with cold outlets, both within one unified structure. This merging reduces the number of separate components needed in the plumbing system while maintaining the ability to distribute both hot and cold fluids independently to multiple locations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distribution device is designed to perform multiple functions simultaneously - distributing both hot and cold fluids through a single device. The universal design allows one distribution device to replace what would traditionally require two separate devices, thereby reducing system complexity while preserving full distribution capability for both fluid types.

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

2Loss of energy

If hot and cold fluid lines are distributed separately, then thermal insulation is improved, but the installation process becomes more time-consuming and labor-intensive

Engineering Contradiction:
Improvethermal insulationVSAvoidinstallation time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

By integrating hot and cold distribution functions into a single device with a unified structure, the patent reduces installation time and labor requirements. The combined design allows installers to mount one device rather than coordinating installation of multiple separate devices, while the internal structure maintains proper thermal insulation between hot and cold sections.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distribution device incorporates thermal insulation specifically where needed - between the hot fluid distribution section and the cold fluid distribution section. This localized insulation approach maintains thermal efficiency without requiring insulation throughout the entire device, balancing energy conservation with installation efficiency.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If a one-piece structure is used for the distribution device, then manufacturing and installation are simplified, but adaptability to different configuration requirements may be reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidconfiguration flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent creates a one-piece integrated distribution device that combines hot and cold distribution sections into a single manufactured component. This unified structure simplifies manufacturing processes and installation procedures while incorporating multiple outlets and distribution pathways that provide configuration flexibility for different plumbing layouts.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Within the one-piece structure, the distribution device is segmented into distinct functional sections - hot fluid distribution areas and cold fluid distribution areas - with separate outlet configurations. This internal segmentation allows the single device to accommodate various configuration requirements while maintaining manufacturing simplicity through integrated production.

Inventive Principle:
Principle #1Segmentation
