Solution Overview

Problem

Existing systems for supplying foam precursors to multiple foam machines are complex and expensive, requiring cumbersome piping and pumping systems, which complicates recycling and maintenance.

Innovation Solution

An apparatus comprising intermediate bulk containers with batcher stands and pumps that connect to foam machines via supply lines, allowing for efficient and flexible delivery of foam precursors, with quick connect fittings and remote batcher stands for reduced handling and increased recycling potential.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a complicated system of piping and pumps is constructed to supply foam precursors to multiple machines, then the foam machines can be supplied efficiently, but the system becomes expensive and difficult to maintain and recycle

Engineering Contradiction:
Improvesupply efficiency to multiple machinesVSAvoidpiping and pumping system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the foam precursor supply into separate intermediate bulk containers (IBCs) for each machine, with each IBC equipped with its own batcher pump. This segmentation eliminates the need for complex interconnected piping systems while maintaining efficient supply to multiple machines, as each machine has its dedicated supply pathway.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each foam machine is paired with its own IBC and batcher pump, creating a self-contained supply unit. The batcher pump automatically meters and transfers foam precursor from the IBC to the machine without requiring external control systems or complex piping, enabling autonomous operation and simplifying maintenance.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If totes are returned and recycled, then environmental sustainability is improved, but the pumping system prevents recycling

Engineering Contradiction:
Improvetote recycling capabilityVSAvoidpumping system interference
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The batcher pump is extracted from the IBC structure and positioned externally, connected only through simple bottom outlet connections. This separation allows the IBC totes to be easily detached, cleaned, and recycled without any pumping system components attached, while the pumps remain as separate reusable assets.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables easy discarding of used foam precursor from the IBC and recovering/recycling of the IBC tote itself. The simple connection design allows rapid detachment of totes for recycling programs, while the batcher pumps are recovered and reused with new totes.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If batcher pumps are inserted into the top opening of the tote, then the pumps can supply foam precursor, but the pumps must be handled during every tote change

Engineering Contradiction:
Improvepump insertion and removalVSAvoidtime for pump handling during tote changes
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system segments the pump from the tote by providing each IBC with its own dedicated batcher pump that connects at the bottom outlet. This eliminates the need to insert or remove pumps through top openings during tote changes, as pumps remain permanently mounted to their respective IBCs or are automatically connected through bottom outlets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The batcher pumps are pre-positioned and pre-connected to the IBC bottom outlets before tote changes occur. When a tote is replaced, the new tote is already configured with its batcher pump connected at the bottom, eliminating the time-consuming process of inserting pumps during tote changes.

Inventive Principle:
Principle #10Preliminary action
