Solution Overview

Problem

In water treatment systems, the use of distributor baskets leads to issues during servicing, where water treatment media settlement causes difficulties in resecuring the valve assembly, resulting in water leakage and media disturbance, affecting treatment performance.

Innovation Solution

A distributor plate with radial slits in a thermoplastic polymeric disk is used, allowing for fluid flow that swirls around a central opening, supporting water treatment media and enhancing backwashing efficiency by ensuring optimal media contact and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a distributor basket with narrow slits is used to prevent media from flowing into the dip tube, then media prevention is improved, but during servicing media settlement occurs making it difficult to re-secure the valve assembly

Engineering Contradiction:
Improvemedia preventionVSAvoidvalve assembly resecuring
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The distributor basket is segmented into multiple vertical sections or levels, each with progressively wider openings from bottom to top. This segmentation allows media to be contained effectively at lower levels during operation while providing adequate clearance and access at upper levels during servicing, resolving the contradiction between media prevention and ease of valve assembly resecuring.

Inventive Principle:
Principle #1Segmentation

2Reliability

If high pressure water is pumped through the dip tube to flush media away from the distributor basket, then media disturbance is reduced, but water leakage onto the floor occurs creating a mess

Engineering Contradiction:
Improvemedia distributionVSAvoidwater leakage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

A removable access plate or service cover is introduced as an intermediary component between the distributor basket and the external environment. This intermediary allows controlled access for flushing media away from the distributor basket during servicing while containing the water flow within the system, preventing water leakage onto the floor while maintaining reliable media distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the distributor basket is positioned to allow media flow, then media distribution is achieved, but water treatment performance is adversely affected

Engineering Contradiction:
Improvemedia distributionVSAvoidwater treatment performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The distributor basket incorporates adjustable or movable components that allow the system to dynamically adapt between operational mode (optimized for media distribution) and servicing mode (optimized for maintenance access). This dynamic adjustment enables the system to achieve both effective media distribution during operation and proper media containment during servicing, maintaining water treatment performance while enabling productivity.

Inventive Principle:
Principle #15Dynamics
