Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The chassis of existing containers for transporting synthetic resin is easily damaged due to poor arrangement reasonability of cross beams, leading to high transportation costs and cargo loss.
Innovation Solution
A container chassis design with varying heights of cross beams, including first and second cross beams, where the height ratio is between 0.5 and 0.8, and strategically arranged support assemblies to enhance structural strength and reduce weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a universal structure with uniform cross beams is used in the chassis, then the manufacturing is simple, but the structural strength is insufficient and the chassis is easily damaged
Solution Approach 1:
The patent applies local quality by varying the heights of cross beams at different positions along the chassis. The first cross beam has a first height and the second cross beam has a second height different from the first height, creating localized structural variations that optimize strength distribution according to the actual load requirements of different chassis sections, thereby resolving the contradiction between uniform simplicity and localized strength requirements.
Solution Approach 2:
The patent segments the cross beam structure into multiple groups (first cross beam group, second cross beam group, etc.) with different configurations. Each group contains cross beams with specific height variations arranged in sequences, allowing the chassis to be divided into functional zones with optimized structural properties for different transportation scenarios.
2Strength
If more cross beams are added to increase structural strength, then the chassis becomes stronger, but the weight increases
Solution Approach 1:
The patent uses local quality to vary cross beam heights rather than uniformly increasing all beam dimensions. By creating localized height variations (first height vs. second height) in specific cross beam groups, the structure achieves enhanced strength where needed while maintaining lower weight in other areas, optimizing the strength-to-weight ratio.
Solution Approach 2:
The patent introduces dynamic adaptability through different arrangement sequences of cross beams with varying heights. The first arrangement sequence and second arrangement sequence provide different structural characteristics that can be selected based on transportation requirements, allowing the chassis to optimize its strength-weight characteristics for different operational conditions.

AI summary
The present invention provides a container chassis and a container with the container chassis. The container chassis includes a chassis part, the chassis part including a first side beam; a second side beam, the second side beam and the first side beam being arranged at an interval; a plurality of cross beam groups arranged between the first side beam and the second side beam at intervals, each of the plurality of cross beam groups including a plurality of first cross beams; and a plurality of second cross beams, at least one second cross beam being arranged between any two adjacent cross beam groups of the plurality of cross beam groups, wherein the height of the first cross beam is less than the height of the second cross beam. The technical solution of the present application effectively solves the problem that the chassis is easily damaged due to the fact that the arrangement reasonability of cross beams in a container chassis in related technologies is poor.
