Solution Overview

Problem

Existing transport and storage containers for liquids have a high empty weight, which affects stability and increases transportation costs, and they are not adequately designed to handle aggressive liquids.

Innovation Solution

A transport and storage container with a plastic injection-molded base featuring longitudinal and transverse beads for enhanced stability, allowing for reduced material thickness, lower tare weight, and the use of recycled plastic, along with a skid pallet design that increases nominal volume without altering external dimensions, and incorporates a drainage system for aggressive liquids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the base material thickness is increased to improve stability, then the stability is improved, but the empty weight and manufacturing cost increase

Engineering Contradiction:
Improvebase stabilityVSAvoidempty weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The base is segmented into multiple functional layers including a drainage layer, intermediate layer, and upper layer, each with specific thicknesses and properties. This segmentation allows optimization of stability without requiring uniform thick material throughout, reducing overall weight while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a vertical dimension to base design by creating a multi-layered structure with drainage channels and varying thicknesses at different heights and positions. This dimensional approach provides enhanced stability through structural complexity rather than simply increasing material thickness uniformly

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

2Stability of the object's composition

If the base material thickness is increased to improve stability, then the stability is improved, but the manufacturing cost increases

Engineering Contradiction:
Improvebase stabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The base is divided into multiple manufacturable layers that can be produced separately and assembled, allowing for cost-effective manufacturing of complex structures without requiring expensive monolithic thick-base production

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention optimizes various parameters including layer thicknesses, material densities, and structural configurations to achieve the required stability at minimum manufacturing cost, rather than simply increasing all parameters uniformly

Inventive Principle:
Principle #35Parameter changes

3Volume of moving object

If the external dimensions are increased to improve volume, then the nominal volume is increased, but the handling requirements and ground clearance requirements change

Engineering Contradiction:
Improvenominal volumeVSAvoidhandling requirements
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The invention increases volume by utilizing vertical space through multi-layered base structures and optimized internal configurations rather than increasing horizontal footprint, maintaining compatibility with standard handling equipment and ground clearance requirements

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

AI summary

The container (1) has an inner container (2) made of plastic, and an outer casing (14) made of metal grating or sheet metal. A base frame (17) is made of plastic and formed with a runner pallet (18) or a frame pallet. The base frame has a base (21) supported on support legs e.g. central support legs (25), of a central runner (22) and two outer runners (23, 24). The base is made of plastic and formed as an injection molded part. The base has a longitudinal corrugation and a transverse corrugation that are provided for reinforcing the base and as a support for the inner container.
