Galvanized Truck Deck Assembly Using Fastened Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot dip galvanization methods require a large vat to accommodate the entire assembled deck assembly, which is inefficient and costly, especially for uniquely shaped or sized assemblies, and welding during assembly can compromise the integrity of the galvanized components.
Innovation Solution
Hot dip galvanization is performed on individual or grouped components of the deck assembly, which are then assembled using fasteners instead of welds, allowing the use of a smaller vat and reducing costs while maintaining corrosion protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire assembled deck assembly is hot dip galvanized, then complete corrosion protection is achieved, but a large and costly vat is required
Solution Approach 1:
The deck assembly is divided into individual components or subassemblies that are hot dip galvanized separately in a smaller vat, then assembled after galvanization using fasteners rather than welding. This segmentation allows complete corrosion protection of all metal surfaces while using a much smaller, more cost-effective galvanizing vat.
2Strength
If components are welded together before galvanization, then structural integrity is maintained, but the galvanized coating integrity is compromised
Solution Approach 1:
Components are hot dip galvanized individually before assembly, establishing the protective coating first. Then components are assembled using fasteners that do not require welding, thereby preserving the integrity of the galvanized coating while maintaining structural integrity of the deck assembly.
3Volume of stationary object
If individual components are hot dip galvanized, then a smaller vat is used reducing costs, but components must be assembled after galvanization
Solution Approach 1:
The deck assembly is segmented into individual components or subassemblies that can be hot dip galvanized separately in a smaller, more cost-effective vat. After galvanization, components are assembled using fasteners rather than welding, which maintains structural integrity while preserving the protective coating. This segmentation approach reduces vat size requirements and overall manufacturing costs.
4Reliability
If the assembled deck assembly is hot dip galvanized, then all surfaces are protected, but manufacturing costs increase
Solution Approach 1:
Individual components or subassemblies are hot dip galvanized separately rather than galvanizing the complete assembled deck assembly. This segmentation allows use of a smaller vat, reducing capital equipment costs and manufacturing expenses while achieving complete corrosion protection of all metal surfaces through subsequent assembly of galvanized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the size of the required galvanization vat and lowers manufacturing costs by enabling the assembly of components post-galvanization, ensuring effective corrosion protection without the limitations of welding.
Implementation Method 1
In hot dip galvanization, component(s) are coated with a material comprising zinc to protect against corrosion. Component(s) may be positioned in a vat holding molten material comprising zinc.

AI summary
A deck assembly for a truck body of a vehicle is provided. The deck assembly is formed by a process. This process comprises hot dip galvanizing a first component that comprises metal, comprises hot dip galvanizing a second component that comprises metal, and attaching the first component and the second component together using fasteners. When the first component and the second component are attached together using fasteners, the components are not attached together using welds. Hot dip galvanization may result in the deposition of material comprising zinc onto the first component and the second component to prevent corrosion in the first component and the second component. All metal components of the deck assembly may be hot dip galvanized separately and then fastened together.
