Modular Sheet Metal Shipping Base for Repairable Logistics

Solution Overview

Problem

Current shipping bases, particularly wooden pallets, are often disposable and costly to repair or replace due to damage from handling, and they pose challenges in international shipping due to the risk of pest transport, necessitating more expensive alternatives like plastic or metal pallets that are also costly and not easily repairable.

Innovation Solution

A modular shipping base made from stamped or cut sheet metal components that can be easily repaired by replacing damaged parts using a tab system, adhesive, or welding, allowing for quick and cost-effective maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wooden pallets are used for shipping, then they are inexpensive and easy to manufacture, but they are disposable and costly to repair or replace when damaged

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The shipping base is divided into multiple replaceable components including a deck pan, four corner supports, and side panels. Each component can be independently removed and replaced if damaged, eliminating the need to replace the entire base. This segmentation enables cost-effective repair by allowing only the damaged portion to be substituted.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design allows damaged components to be discarded and replaced with new or refurbished parts. The modular structure facilitates easy removal of damaged components and attachment of replacement parts, making the repair process economical and efficient compared to traditional wooden pallets that require complete replacement.

Inventive Principle:
Principle #34Discarding and recovering

2Object-affected harmful factors

If plastic or metal pallets are used to avoid pest transport, then pest transport risk is eliminated, but they are costly and not easily repairable

Engineering Contradiction:
Core Design Contradiction:
Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The base is constructed from metal components that can be segmented into replaceable parts. This segmentation combined with the use of non-organic metal materials eliminates pest transport risk while maintaining ease of repair through component replacement, resolving the contradiction between pest prevention and repairability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shipping base uses metal materials (such as steel or aluminum) that are non-organic and resistant to pest infestation. These metal components maintain structural integrity and can be repaired or replaced, combining the pest-resistant properties of metal with the repairability enabled by modular design.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If traditional wooden pallets are used, then they are inexpensive initially, but labor and logistics costs for repair exceed replacement costs

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

By segmenting the base into standardized, interchangeable components, the design enables rapid replacement of damaged parts without requiring complex repair procedures. This reduces labor time and logistics costs associated with repair, making the overall system more economically efficient despite potentially higher initial component costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design changes the economic parameters by shifting from a low-initial-cost/high-repair-cost model (wooden pallets) to a balanced model where moderate initial costs are offset by significantly reduced repair costs and extended service life through component replacement and refurbishment capabilities.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If shipping bases are designed for reusability, then shipping costs are reduced, but damaged components cannot be easily replaced

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The modular architecture with independently replaceable components directly enables reusability while maintaining ease of repair. When a component becomes damaged, only that specific component needs to be replaced rather than the entire base, thereby extending the operational life of the base and reducing shipping costs through repeated reuse.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design facilitates discarding only the damaged component while recovering and retaining the undamaged portions of the base. This selective replacement approach maximizes reusability by keeping the majority of the base structure in service while eliminating damaged parts, thereby reducing overall shipping costs through extended base utilization.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

A re-usable, returnable, stackable, modular shipping base incorporates replaceable components to make the base relatively quick and cost effective to repair. The shipping base is formed from a number of stamped or cut sheet materials (e.g., sheet metal) that are then folded and attached to one another using a tab system. When a component is damaged, the damaged component may be removed from the base and replaced with another mass produced, stamped sheet material component. Components are attached to one another via adhesive, stitch welding, skip welding, spot welding, or any other applicable process. Some components (e.g., a center support) may also be assembled using a tab (from the center support) and slot (in a deck pan) system.
