Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Residential wooden decks face issues such as frequent cleaning needs, mold and mildew growth, and material degradation, including splitting and distortion, which can lead to costly replacements.
Innovation Solution
A metal deck kit comprising metal joists, rim tracks, connectors, girders, and support posts, along with a method for erecting a metal deck platform that includes securing metal posts, girders, joists, and rim tracks to form a stable and durable platform, optionally with metal stairs and handrails, allowing for the use of non-metallic decking materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If treated wood is used for deck construction, then the deck provides natural appearance and durability, but frequent cleaning and waterproofing are required and material degradation occurs
Solution Approach 1:
The patent changes the material parameter from organic wood to inorganic metal (aluminum or steel), fundamentally altering the chemical and physical properties. This substitution eliminates the need for waterproofing and reduces cleaning frequency while maintaining structural durability, directly resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The deck system uses composite construction combining metal framing members with decking boards that can be either metal or alternative materials. This composite approach allows the structural framework to provide durability while the decking surface can be selected for low maintenance, simultaneously achieving both reliability and ease of operation
2Ease of operation
If polymer-based materials are used for decking, then waterproofing is not required and cleaning frequency is reduced, but localized swelling and fiber blousing occur near fastener holes
Solution Approach 1:
The patent changes the material parameter from polymer-based composite to metal (aluminum or steel) for the decking boards. This substitution eliminates the localized swelling and fiber blousing issues that occur with polymer materials near fastener holes, while maintaining the low maintenance advantage, thus resolving the contradiction between ease of operation and material stability
Solution Approach 2:
The metal decking boards provide uniform material properties throughout, eliminating the localized defects that occur in polymer materials near fastener holes. The consistent material composition and structure prevent localized swelling and blousing, resolving the stability issue while maintaining low maintenance requirements
3Strength
If treated wood posts and girders are used, then the deck structure provides initial strength, but splitting and distortion occur over time requiring replacement
Solution Approach 1:
The patent changes the material parameter from treated wood to metal (aluminum or steel) for the structural framing members including posts, girders, and joists. This substitution provides equal or superior initial strength while dramatically extending the service life by eliminating splitting and distortion issues, thus resolving the contradiction between strength and duration of action
Solution Approach 2:
By using metal framing members, the patent eliminates the need for periodic replacement of wooden posts and girders that suffer from splitting and distortion. The metal components provide long-term durability, reducing lifecycle costs despite potentially higher initial material cost, resolving the contradiction between initial strength and service life
