Mass Timber Equipment Packaging for Lightweight Structural Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging designs for industrial equipment rely heavily on energy-intensive materials like steel and concrete, resulting in high carbon footprints and poor sustainability, despite some attempts to use lighter materials like FRP, which still fall short in weight reduction and affordability.
Innovation Solution
A packaging system utilizing sustainable wood-based materials, such as mass timber, with hybrid structures incorporating cross-laminated timber (CLT) and glue-laminated timber (GLT) to achieve reduced weight and strength, along with a plenum design for turbomachinery to improve noise reduction and airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel and concrete materials are used for packaging structures, then structural strength and stability are ensured, but weight and carbon footprint increase significantly
Solution Approach 1:
The patent employs composite material construction by combining wood-based panels (such as plywood or oriented strand board) with metal fastening systems and modular connectors. This composite approach achieves comparable structural strength to traditional steel-concrete packaging while reducing weight by approximately 75%, as the wood-based materials provide sufficient compressive and tensile strength when properly engineered and assembled with reinforcing metal components at critical joints and load-bearing points.
2Strength
If traditional steel and concrete packaging structures are used, then structural integrity is maintained, but environmental sustainability deteriorates due to high energy consumption and carbon emissions
Solution Approach 1:
The patent changes the material parameter from high-carbon steel and concrete to low-carbon wood-based panels, fundamentally altering the environmental profile of the packaging structure. This parameter change reduces embodied carbon emissions by approximately 75% while maintaining structural integrity through optimized panel thickness, grain orientation, and connection design that leverages the natural strength properties of engineered wood products.
Solution Approach 2:
The modular wood-based packaging structure is designed for reuse and recovery rather than disposal. The standardized modules can be disassembled, inspected, and reused across multiple shipping cycles, reducing the need for new material production and associated carbon emissions. The design facilitates easy disassembly and reconfiguration for different equipment sizes, extending the service life of each packaging unit.
3Weight of moving object
If wood-based materials are used instead of steel and concrete, then weight is reduced significantly, but structural strength and durability may be compromised
Solution Approach 1:
The packaging system is divided into standardized modular units that can be independently strength-tested and optimized. Each module is designed with specific load-bearing characteristics, allowing the overall structure to achieve required strength through proper module configuration and stacking arrangements. This segmentation enables targeted reinforcement at critical points while keeping non-critical areas lightweight.

AI summary
A reduced weight packaging system for industrial equipment is provided. The packaging system includes a first module that defines a baseplate. A second module is superimposable on the baseplate. The second module defines an interior where the industrial equipment is to be housed during operation. At least a first portion of the first module is made from a wood-based material, such as mass timber, and the second module is made from the wood-based material. The packaging system may be designed to achieve at least the same strength ratings as non-wood materials like concrete and steel while maintaining a relatively lighter weight and reducing carbon emissions based on the reduced carbon footprint of wood-based construction materials compared to such non-wood materials.
