Solution Overview
Problem
Traditional deck construction methods are time-consuming, costly, and require specialized skills, making them inaccessible to most homeowners, and often result in substandard outcomes due to lack of standardized, user-friendly solutions and proper installation techniques.
Innovation Solution
A subfloor system comprising pre-notched beams, joists, and frame units that automatically square and secure without manual measurements, using fastening means like screws and brackets, allowing DIY construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional deck construction methods are used, then structural strength and reliability are improved, but construction time and cost increase significantly
Solution Approach 1:
The deck construction system is divided into modular components including pre-cut beams with notches, pre-cut joists with notches, and standardized frame units. These segmented modules can be independently manufactured and assembled, dramatically reducing construction time while maintaining structural integrity through standardized connection points.
Solution Approach 2:
Critical structural elements such as beams and joists are pre-notched during manufacturing to ensure precise fit and proper structural alignment. This preliminary action eliminates the need for on-site measuring and cutting, allowing homeowners to assemble the deck framework quickly while ensuring professional-grade structural strength without requiring specialized skills.
2Stability of the object's composition
If traditional deck construction methods are used, then structural stability is improved, but ease of operation deteriorates due to specialized skill requirements
Solution Approach 1:
The system segments the construction process into simple assembly tasks using pre-prepared modules. Homeowners only need to perform basic assembly operations like fitting pre-notched components together and securing them with fasteners, eliminating the need for complex measuring, cutting, and squaring operations that traditionally required specialized carpentry skills.
Solution Approach 2:
The pre-notched design allows the structural components to self-align and self-square during assembly. The notches are precisely positioned to automatically guide proper placement of beams and joists, enabling homeowners to achieve structurally stable construction without needing professional training in deck building techniques.
3Ease of manufacture
If standardized pre-notched components are used, then ease of manufacture is improved, but manufacturing precision requirements increase
Solution Approach 1:
The notches are manufactured in advance during the component production process using automated cutting equipment. This preliminary action allows for precise notching under controlled factory conditions, ensuring consistent fit and alignment while simplifying the overall manufacturing process compared to on-site customization.

AI summary
The invention describes a subfloor or a split subfloor system for use in the construction of a portable deck. The proposed subfloor system can be installed without any special skill set or tools. The subfloor comprises of several footings that are arranged on the ground, at least two pre-notched beams that are placed on the footings, at least two pre-notched joists that rest perpendicularly on the pre-notched beams, at least two frame units that rest perpendicularly on the pre-notched beams in a direction parallel to the pre-notched joists, and at least one rim joist secured to each end of the pre-notched joists and the frame units. These components of the subfloor system could also be split in two or more pieces for a split subfloor system that makes transportation easier. A kit comprising the components of the subfloor system and a method of construction is also provided.
