Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trailers are heavy and bulky, leading to reduced fuel economy due to increased weight and wind drag, and require specialized tools and extensive welding for assembly, which is inefficient and costly.
Innovation Solution
A lightweight trailer floor design with structural reinforcements, including sidewalls and cross-members that inhibit flexion, allowing the use of thinner materials while maintaining the same weight-bearing capacity as conventional trailers, and enabling easier assembly without specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavier floor material and cross-members are used, then weight bearing capacity increases, but trailer weight increases leading to reduced fuel economy
Solution Approach 1:
The floor panel is segmented into multiple components: a base panel, vertical sidewalls extending from the panel edges, and cross-members positioned within slots formed by the sidewalls. This segmentation allows each component to perform its specific function efficiently, distributing structural loads through the sidewalls to the cross-members while using lighter gauge material for the base panel.
Solution Approach 2:
The invention adds vertical dimension by extending sidewalls upward from the base panel, creating a three-dimensional structural framework. This vertical dimension allows the sidewalls to act as load-bearing elements that transfer forces from the base panel to the cross-members, enabling the use of thinner base panel material while maintaining overall structural strength.
2Stability of the object's composition
If thicker floor material is used, then flexion resistance improves, but trailer height increases resulting in more wind drag
Solution Approach 1:
The floor structure is divided into a thin base panel and separate vertical sidewall elements. The sidewalls, rather than increasing base panel thickness, provide the necessary structural support against flexion by acting as stiffening ribs that transfer loads to the cross-members, thus maintaining flexion resistance without increasing overall panel height.
Solution Approach 2:
The invention creates a composite structural system combining a thin base panel with vertical sidewall extensions and horizontal cross-members. This composite structure achieves superior flexion resistance through the synergistic interaction of its components, where the sidewalls and cross-members provide rigid support while the thin base panel provides a continuous load-distributing surface.
3Strength
If conventional floor construction is used, then structural strength is achieved, but assembly requires specialized tools and extensive welding
Solution Approach 1:
The floor system is segmented into modular components (base panel, sidewalls, cross-members) that can be manufactured separately and assembled through simple mechanical connections. The sidewalls include integrated slots that receive cross-members, eliminating the need for welding or specialized assembly tools while maintaining structural integrity through the interlocking design.
Solution Approach 2:
The sidewalls are designed with built-in slots that automatically position and support the cross-members during assembly. The cross-members fit into these slots and are retained by the sidewall structure, creating a self-aligning, self-supporting assembly system that requires no external tools or specialized welding procedures.
4Weight of moving object
If lighter floor material is used, then trailer weight decreases improving fuel economy, but weight bearing capacity is reduced
Solution Approach 1:
By transitioning from a two-dimensional flat panel to a three-dimensional structure with vertical sidewalls, the invention enables lighter base panel material to be used. The sidewalls provide the additional structural support in the vertical dimension, transferring loads to the cross-members and allowing the base panel to be constructed from lighter gauge material while maintaining weight bearing capacity.
Solution Approach 2:
The invention employs a composite construction where a thin, lightweight base panel is combined with vertical sidewall elements and horizontal cross-members. This composite structure distributes loads throughout the entire assembly rather than relying on the base panel alone, enabling the use of lighter materials while achieving the required weight bearing capacity.

AI summary
A panel for constructing a trailer floor is provided. The panel includes a platform from which a plurality of sidewalls extend from a first edge and a second edge, with slots therebetween for receiving cross members. The sidewalls engage with the cross members to inhibit movement of the sidewalls away from the slots, which simultaneously inhibits the panel from flexing. The inhibition of flexure of the panel increases the load carrying capacity of the panel, allowing utilization of lighter materials to achieve the same load carrying capacity as heavier materials.
